The Northwest of Iran, covering the three provinces of Ardabil, East Azerbaijan and West Azerbaijan, is a special area that, due to its particular geographical and climatic conditions has a rich biodiversity. The present study was conducted with the aim of studying the habitat, substrate type, feeding, conservation and distribution of lizards in this area from 2003 to now. Our results have revealed that there are 20 lizard species belonging to 13 genera and 5 families in this area. Lacertid lizards have the highest species diversity with 12 species. We also found that high ranges of habitats with a different substrate types are inhabited by lizard species. The number of species in pine regions compared with other types of area is considerably greater. The conservation status of lizards is unknown and requires further study.

Northwestern Iran has unique geographical and climatic conditions that support a rich flora and fauna. In view of the lack of in-depth studies on the lizards of the region, an investigation was started in the northern part of Ardabil Province for an inventory of this component of the fauna and their habitats. Collections were made from October 2003 to June 2005 and 165 specimens were collected and identified. Five families, 12 genera and 15 species are represented, including Agamidae: Laudakia caucasia, Phrynocephalus persicus, Trapelus ruderatus; Lacertidae: Lacerta media media, Lacerta strigata, Lacerta brandtii, Darevskia raddei raddei, Eremias strauchi strauchi, Eremias arguta, Ophisops elegans; Scincidae: Mabuya aurata transcaucasica, Eumeces schneiderii princeps, Abelepharus bivittatus; Anguidae: Pseudopus apodus and Gekkonidae: Cyrtopodion caspium caspium. Comparing this list to the data provided by Anderson (1999), it seems that most of the lizards are being reported for the Province for the first time. The families Gekkonidae and Anguidae are newly recorded, and the gecko Cyrtopodion caspium is first recorded from the west and northwest of Iran. With seven species represented in the area, lacertids have the highest species diversity among the lizard families and need further study. Habitat features also have been given for all species.

The Iranian Plateau is an area of highly complex landscape and incredibly diverse habitats, from salt deserts to temperate forests. Such a heterogeneous environment, at the crossroads of Asia, Europe, and Africa, fuels the high diversity and uniqueness of the Iranian fauna and flora. Nevertheless, our understanding of the historical processes that shaped the Iranian biodiversity remains limited. In this context, we revisit the evolutionary history of the two most widespread lizard species on the Iranian Plateau (Eremias persica and Mesalina watsonana) to explore whether these two taxa of similar ecology have been subjected to similar historical processes. To achieve that, we performed a series of phylogenetic analyses and thoroughly tested all possible alternative topologies based on available mitochondrial sequences (cytochrome b and 12S ribosomal RNA). Additionally, we estimated the number of mitochondrial clusters based on a novel single-locus delimitation method and the time of their divergence, using recently inferred evolutionary rates for lacertid species. The results indicate that the two taxa have been shaped by similar physiographic and climatic barriers since both phytogenies split into similar geographical clusters. However, E. persica has twice as long evolutionary time on the Iranian Plateau than M. watsonana. The first divergence of E. persica was estimated in the Middle Miocene (~13 Mya), at the time of the major uplift of the Zagros mountain range. The Upper Miocene tectonic rearrangement that resulted in the uplift of the Alborz mountains coincides with the original split in M. watsonana (~6.6 Mya) and several contemporaneous splits within E. persica.

We studied, for the first time, the age structure of Eremias strauchi strauchi (Kessler, 1878) from a sample (18 adults) of a population living in the vicinity of Iğdır (eastern Turkey) using the skeletochronological method. The maximum observed longevity was 7 years for males and 5 years for females. The age of males ranged from 4 to 7 years (mean 4.91, n = 12), while that of females ranged from 4 to 5 years (mean 4.66, n = 6). The average snout–vent length (SVL) was 61.10 mm in males and 60.82 mm in females. The differences in mean age and SVL between sexes were not statistically significant. Intersexual differences in body size were male-biased, but this state was not statistically significant. Age and SVL were positively correlated in both sexes.

Morphologic diversity was studied in 129 species of lacertid lizards and their relationship with ecology by means of comparative analysis on seven linear morphometric measurements. Body size is the most important variable determining, a continuum among small bodied species and larger ones independently evolved through the lacertid phylogeny. This variable is strongly and positively correlated with the others masking the patterns of morphologic diversity. Multivariate analysis on size-adjusted variables show a negative covariation among relative tail and limb length. Remarkably, arboreal and semiarboreal species (Takydromus and the Equatorial African clade) appeared two times independently during the evolution of lacertids and are characterized by extremely long tails, and relatively long forelimbs in comparison with hindlimb length. The arboreal and glider lizard Holaspis with their short tail constitute the only exception. Another case of convergence is found by some species dwelling into dense vegetation or grass (Tropidosaura, Lacerta agilis, Takydromus amurensis or Zootoca) which have long tails and short limbs. On the opposite, species living in deserts, steppes or scrublands with scarce vegetation isolated into extended open areas have developed long hindlimbs and short forelimbs to achieve higher speed and maneuverability This is especially the case of Acanthodactylus and Eremias.

Morphometric evaluation of limb proportions in five sympatric desert lacertas of the genus Eremias, namely E. velox, E. grammica, E. intermedia, E. lineolata, and E. scripta inhabiting southern Balkhash Lake region (Sary-Ishyk-Otrau desert), Kazakhstan, was made. Considerable species differences in proportions of some limb segments associated with locomotion adaptations (burrowing, climbing etc) of these lizards have been found as well as sexual dimorphism and age variability. Associations among morphometric peculiarities (limb proportions), locomotion activity, spatial, temporal, and trophic characteristics of ecological niches of sympatric species are discussed.

The scientific biography of the outstanding herpetologist and specialist in zoogeography Sergei Alexandrovich Chernov (1903–1964) was reconstructed on the base the study of archival materials and literature sources. The text is divided into four parts, reflecting the main stages of his biography: 1903–1930 – Kharkiv, the beginning of the scientific career; 1930–1941 – relocation to Leningrad, Tajik-Pamir expedition; 1941–1945 – Great Patriotic War and evacuation; 1945–1964 – period after the Great Patriotic War. In the paper, we emphasize the line of teacher–student continuity begun by A.M. Nikolsky and S.A. Chernov in the herpetology department of the Zoological Institute of the Russian Academy of Sciences. The appendix contains a list of his publications (52 ti- tles), taxa, described by him (11) and named in his honor (6). In majority of his publications, Chernov was the sole author; most of them were published in Russian; only one paper was written in a foreign (German) language. One of the main achievements of Chernov should be recognized a publication of the Guide of amphibians and reptiles of the USSR together with P.V. Terentyev. He made the greatest contribution to the study of the systematics of lizards and snakes, composition, zoogeography, and the history of the formation of the herpetofauna of Central Asia. According to his studies, the fauna of Central and Central Asia are subsidiaries of the once united region, what contradicted the views of his teacher Nikolsky, who developed the concept of M.A. Menzbir about the young postglacial origin of the Aral-Caspian deserts and the ancient, Eocene origin of the deserts of Central Asia.

Twenty-four species of lacertid lizards were examined at 31 sites in western Yogoslavia, Greece and Iberia. Comparative observations were made on over 4500 individual lizards, noting such features as times of activitiy, hunting methods, diet, micro- and macrohabitat, refuges used and body temperature. These data are used as a basis for assessing resource partition in related sympatric species, for find out whether different systematic groups have characteristic types of niche, and for comparing cumminity structures in the peninsulas of southern Europa.

Differences in surface structure (ober- hautchen) of body scales of lacertid lizards involve cell size, shape and surface profile, presence or absence of fine pitting, form of cell margins, and the occurrence of longitudinal ridges and pustular projections. Phylogenetic information indicates that the primitive pattern involved narrow strap-shaped cells, with low posteriorly overlapping edges and relatively smooth surfaces. Deviations from this condition produce a more sculptured surface and have developed many times, although subsequent overt reversals are uncommon. Like variations in scale shape, different patterns of dorsal body microornamentation appear to confer different and conflicting performance advantages. The primitive pattern may reduce friction during locomotion and also enhances dirt shedding, especially in ground-dwelling forms from moist habitats. However, this smooth microornamentation generates shine that may compromise cryptic coloration, especially when scales are large. Many derived features show correlation with such large scales and appear to suppress shine. They occur most frequently in forms from dry habitats or forms that climb in vegetation away from the ground, situations where dirt adhesion is less of a problem. Microornamentation differences involving other parts of the body and other squamate groups tend to corroborate this functional interpretation. Microornamentation features can develop on lineages in different orders and appear to act additively in reducing shine. In some cases different combinations may be optimal solutions in particular environments, but lineage effects, such as limited reversibility and different developmental proclivities, may also be important in their genesis. The fine pits often found on cell surfaces are unconnected with shine reduction, as they are smaller than the wavelengths of most visible light.

In this paper we deal on the ultraviolet color (invisible to us): where we can find it, the capability of animals to see it and the advantages that this color perception offers to them. As the simplest way to detect it is the photography, we describe and review how to photograph the UV, as a result of 15 years of amateur experience, searching and testing nearly in complete blindness due to the lack of practical information about “how to do it”. We describe the different kinds of photography (chemical and digital); the cameras and objectives suitable (both astronomically expensive ones and cheap options); what are the best characteristics that the objectives should have for this purpose; the films suitable for their use in chemical photography; the different filters (current or discontinued) manufactured along the years; and the subtle combinations among the different materials to obtain pure UV photographs. This kind of scientific photography is mainly used in forensics, forgery detection, art dermatology and less in Natural History, despite the fact that a great part of animals see this color and use it in important questions of their biology as the social behavior, mate choice or the food search.

Animals communicate via a variety of sensory channels and signals. Studies on acoustic and visual communication systems suggest that differences in the physical environment contribute to the variety of signalling behaviour, with species investing in those signals that are transmitted best under the local conditions. Whether or not environmental tuning also occurs in chemical communication systems has received much less attention. In the present study, we examined the effect of several aspects of the physical environment on the chemical communication system of lacertid lizards (family Lacertidae). The numbers of femoral pores are used as a proxy reflecting how much a particular species invests in and relies upon chemical signalling. Femoral pores are specialized epidermal structures that function as a secretion channel for the waxy substance produced by glands. In some lacertid species, the secretion carries infochemicals that play an important role in social communication. The number of femoral pores varies considerably among species. We have compiled data on femoral pore numbers for 162 species and tested for the effects of climate and substrate use. After correcting for body size and taking the phylogenetic relationships among the species into account, we found no effect of climate conditions or latitude on species pore numbers. Substrate use did affect pore numbers: shrub-climbing species tended to have fewer femoral pores than species inhabiting other substrates.

A new species of Eremias has been described from the Cholistan Desert of Pakistan. It constitutes the first record of the genus Eremias from the Oriental (Indian) region. The species has been named Eremias cholistanica, after the Cholistan Desert of Pakistan. This striped desert lacerta is not only different from all its congeners in several morphological characteristics but has been collected from an area distant from the previous known range of Eremias.

×

Present studies are aimed to document the herpetofauna of Cholistan Desert and study its ecology. During the last three years from 2001 to 2003, attempts have been made to collect and observe the amphibians and reptiles in different parts of Cholistan Desert. More than four thousand specimens belonging to 44 species have so far been collected/observed from the study area. Among different collecting techniques adopted for these studies, “Pit-fall” traps and “Hand Picking” showed best results. The voucher specimens have been catalogued and are presently lying with Pakistan Museum of Natural History, Islamabad.

Background. The purpose of the work is to clarify the species of turtles, lizards and snakes that P. S. Pallas noted in the Volga river basin and the Volga-Ural inter fluve. Pallas’s data on the reptile fauna of the region are compared with current data Materials an methods. The basis of the study was the analysis of Pallas’s publications. The names of reptiles used by Pallas with their modern names are identified. Results. From the Volga region, Pallas described two species of reptiles that are new to science: “Coluber melanis” (black forest-steppe form of the Vipera berus) and “Lacerta pipiens” (Alsophylax pipiens). From the interfluve of the Volga and the Ural Pallas described two species yet: “Lacerta apoda” (Pseudopus apodus) and “Lacerta mystacea” (Phrynocephalus mystaceus). The great naturalist noted in the Volga region also reptiles, whose modern names are: Emys orbicularis, Phrynocephalus helioscopus, Phrynocephalus guttatus, Phrynocephalus mystaceus, Eremias velox, Lacerta agilis, Natrix natrix, Natrix tessellata, Hierophis caspius, Gloydius halys, Vipera berus, Vipera renardi. At the beginning of the XXI century, one species of turtles, 11 species of lizards and 10 species of snakes reliably inhabit the region. Conclusions. The species of reptiles noted by Pallas, except for the Pseudopus apodus and the Gloydius halys, reliably inhabit the region at present. The data of the Pallas serve as a basis for studying the dynamics of species composition, distribution, abundance and phenology of reptiles in the Volga basin.

Nine reptile species inhabited on the five sites in the Orenburgsky State Nature Reserve, these are Emys orbicularis, Eremias arguta, Lacerta agilis, Zootoca vivipara, Natrix natrix, N. tessellata, Coronella austriaca, Elaphe dione, and Vipera renardi. Lacerta agilis is the only abundant species. Over the last 20-25 years, the abundance of at least three species (Emys orbicularis, Zootoca vivipara, Natrix natrix) has decreased in some clusters of the reserve.

The information about the northern range boundary of the steppe-runner Eremias arguta (Pallas, 1773) has changed in recent decades. Based on the reliable recordins in 2001-2020 from 12 locations the northern range boundary between Volga and Ural was specified. It runs through the Engelsky District of the Saratov Region, through the Stavropolsky, Kinelsky, Bogatovsky and Borsky Districts of the Samara Region, through the Buzuluksky and Tashlinsky Districts of the Orenburg Region of Russia. The northern limit of the range should be considered the Volga above-floodplain slope in the left-bank part of the Stavropolsky district in Samara region. All specimens encountered had body coloration typical of Eremias arguta deserti (Gmelin, 1789). The locations of steppe-runner are confined to open spaces treeless and without a dense herbaceous vegetation on the southern sandy slopes.

Ilya S. Darevsky co-described 70 taxa (three genera, 46 species, 21 subspecies) in 44 publications belonging to five orders, eight families of amphibians and reptiles during his career in herpetology. Of this number, three taxa are fossil and 57 taxa are currently considered as valid. By the regions where new taxa were discovered Southeast Asia and Western Asia (includes Caucasus and Asia Minor) dominates. The largest number of descriptions was published in the Russian Journal of Herpetology.

A complete catalogue is provided for the type specimens of lacertid lizards in the herpetological collection of the Zoological Museum, Berlin, as of December, 1993. The collection contains a total of 514 type specimens, representing 63 taxa, of which 42 are currently regarded as valid at the specific or subspecific level. Types representing an additional four taxa appear to have been lost from the collection. The collections are especially rich in African lacertid types and in historically significant specimens collected early in the Nineteenth Century by Pallas, Eversmann, and Hemprich & Ehrenberg. Also present are the type series of many subspecies of Podarcis lilfordi and P. pityusensis described by Eisentraut.

Research of the herpethofauna of the Lower Volga area began by academic expeditions of the 18 century. As a result of these researches, many new species of amphibians and reptiles were described. Some of these species descriptions are recognized as the priority ones. The earliest data on amphibians and reptiles in the territory of the current Volgograd region were collected at the beginning of the 19 century (Kondratyev, 1885). Important data on the Sarepta amphibians and reptiles were also published by A. Becker (1855). Later, a new viper species was described on the basis of the Sarepta materials (Christoph, 1861). At the beginning of the 20 century, materials on amphibians and reptiles were collected by V. Kiziritsky in the territory of the Tsaritsyn (currently Volgograd) region (1913). The results of these works are reflected in A. M. Nikolsky`s reports (1915, 1916, and 1918). A next stage of research began in the middle of the 20 century by works of the Stalingrad zoologists (N. A. Kosareva, B. S. Kubantsev, T. I. Zhukova, N. N. Kolyakin, etc.). Later, zoologists from Moscow and other Russian cities conducted their research there as well. The results of all these studies on inventory of the herpethofauna of the Volgograd region are summarized in Professor B.S. Kubantsev’s works (1996, 2003, etc.). Now, local zoologists continue studying the amphibian and reptile fauna of the Volgograd region. A significant contribution to our knowledge on distribution, number and ecology of reptiles was brought by Saratov researchers. But the herpethofauna inside a considerable territory of the Lower Volga area is still poorly studied. Key words: amphibians, reptiles, fauna, study, history, Volgograd region, Russia.

Animals must cope with and be able to move effectively on a variety of substrates. Substrates composed of granular media, such as sand and gravel, are extremely common in nature, and vary tremendously in particle size and shape. Despite many studies of the properties of granular media and comparisons of locomotion between granular and solid substrates, the effects of systematically manipulating these media on locomotion is poorly understood. We studied granular media ranging over four orders of magnitude in particle size, and differing in the amount of particle shape variation, to determine how these factors affected substrate physical properties and sprinting in the generalist lizard Eremias arguta. We found that media with intermediate particle sizes had high bulk densities, low angles of stability and low load-bearing capacities. Rock substrates with high shape variation had higher values for all three properties than glass bead substrates with low shape variation. We found that E. arguta had the highest maximum velocities and accelerations on intermediate size particles, and higher velocities on rock than glass beads. Lizards had higher stride frequencies and lower duty factors on intermediate particle size substrates, but their stride lengths did not change with substrate. Our findings suggest that sand and gravel may represent different locomotor challenges for animals. Sand substrates provide animals with an even surface for running, but particles shift underfoot. In contrast, gravel particles are heavy, so move far less underfoot, yet provide the animal with an uneven substrate.

Locomotor performance in lizards is strongly affected by structural habitat. Understanding this relationship allows us to predict species distributions across habitat types. However, little information is available about the ecological role of the locomotion of multiocellated racerunner (Eremias multiocellata) in the desert steppe ecosystem of Inner Mongolia, China. Herein, we studied the effects of habitat structure on the locomotor performance of this lizard species in the field. We found that the sprint speed of this lizard declined significantly with increasing vegetation coverage. Manipulative experiments were further conducted to examine the effects of branch barriers and surface substrates on the sprint speed of the lizard. We found that the sprint speed was significantly influenced by the surface substrates and branch barriers, and there were no interactions between them. Branch barriers impeded sprint speed, and E. multiocellata showed better locomotor performance on sandy rather than loamy substrates. Our results indicate that E. multiocellata tends to occupy open areas with sandy substrates, but its locomotor performance is not closely associated with habitat preference.

The current book provides a synthesis of the information concern- ing field identification of all the species and subspecies of Amphibia and Reptilia hitherto registered in Bulgaria. It comprises 61 species and 23 subspecies, among which 5 species (Pelophylax lessonae, P. kurtmuelleri, Hemidactylus turcicus, Eremias arguta, Montivipera xanthina) that have not been found yet on the territory of the country, but which are known from sites in proximity to Bulgar- ian frontiers. The frogs and toads are represented with 14 spe- cies, newts and salamanders with 6 species, turtles and tortoises with 7 species (Trachemys scripta introduced; Caretta caretta and Chelonia mydas considered extinct), and snakes with 19 species (Vipera aspis and V. ursinii considered extinct). The structure of each species’ description includes the following headings: Name, Diagnosis, General Distribution, Distribution in Bulgaria, Habitats, and Biology. Besides in Bulgarian and Latin, all species are sup- plemented with their English, French, German and Russian names. All synonyms in the main herpetological literature are listed after the currently accepted Latin name. Original keys for identification of the families, genera and species, based entirely on morphologi- cal characters of adult specimens, as well as on the structure of amphibians’ eggs and larvae, are elaborated to facilitate the users. A photo gallery, comprising original colour photos shot in nature, and numerous line drawings of different key characters are made for better distinction between the species. For purely conservation- al reasons, the distribution maps not only indicate the scientifically confirmed species distribution in the country, but also show the areas with suitable habitats where a given species is likely to oc- cur. The degree of suitability is indicated with a different degree of shading: optimal (black); suboptimal (80% gray); suitable (60% gray); less suitable (20% gray); white means unsuitable. The guide is also introducing the readers to some general aspects of the tax- onomy, systematics, morphology, biology and ecology of herpeto- fauna. Special chapters are devoted to the methods of observation and capture of amphibians and reptiles, first aid after a snake’s bite, and the relationship between herpetofauna – humans. The status of each species according to main biodiversity conservation acts and conventions is given in Table 1. Being the first publication of its kind, the book is intended for professional herpetologists, students or nature lovers.

Reproductive mode data were extracted piecemeal from the literature and superimposed over currently accepted phylogenies to permit estimation of the minimum frequencies with which viviparity (live-bearing) has evolved in lizards, aswell as to facilitateanalysisoffactors hypothesizedto inlluencethis evolution. Viviparity has arisen on at least 45 separate occasions in the Sauria. Each ofthese origins is pinpointed phylogeneticallyas far as is now possible. Ofthese origins, 22 have occurred in the Scincidae, ten in the Iguanidae, five in the Anguidae, two each in the Lacertidae and Gekkonidae, and one each in the Chamaeleontidae, Xantusiidae, Agamidae, and Cordylidae. Further origins may be detected in the Scincidae, Iguanidae, and Diploglossa as phylogenetic relationships are elucidated. Over 19 % of the saurian species are live-bearing, and about 2/3 of the viviparous species are skinks. Most of the sub-generic saurian origins ofviviparity have occurred in cold climates, possibly as an adaptation to facilitate maternal thermoregulation of the developing embryos. Phylogenetic distributions of these origins are consistent with hypotheses that genetic sex-determination of the male-heterogametic type as weil as a tendency towards egg`retention preadapt a lineage for viviparity. Evolution of the live-bearing mode may be constrained by temperature-dependent sex determination, female heterogamety, and formation of highly calcified eggshells.

By the PAAG electrophoretic spectra of Coomassi-stained 61-73 bands from 4 “tissues” (heart, skeletal muscle, kidney, liver proteins) for each of 17 specimens representing at least 3 or 4 species, (Eremias vermiculata Blanf., E. przewalskii Str., E. sp. and E. multiocellata Gunther) were compared.Most of the specimens were collected in Mongolia. Their tree, based on several measures of genetic distances, showed the order of the species listed above, with E. sp., the closest to the point of divergency, and situated between E. przewalskii and the specimen of E. multiocellata from several localities and biotypes. The genetic similarity of the biotypes of the last species is discussed in regard with other data on the body size and proportion, pholidosis, coloration.

In 2018–2019, isolated sandy habitats in the Ferghana oasis were surveyed. The reptile communities in the sands had a similar structure and very high population density, reaching up to 144 ind./ha. In all habi- tats, two racerunner species absolutely predominated, namely, Eremias velox and Eremias scripta, which accounted from 56.9 to 94.5% of the total abundance. In some habitats the dominants included Rusta- mov’s plate-tailed gecko and Strauch’s toad-headed agama. Three endemic lizard species (Phrynocephalus strauchi, Eremias scripta pherganensis, and Teratoscincus scincus rustamowi) had high population density and were classified as common or numerous. They accounted for an average of 52% (34–74%) of the total reptile abundance. The relationship among reptiles and their distribution in their biotopes were described. The current status of the habitats was assessed and few factors affecting the number of reptiles were considered. Due to plowing and watering, the area of sand habitats has decreased by 3.7 times since 1960 (down to about 180 km2). The only protected area (the Yazyavan natural monu- ment) is not enough to maintain the biodiversity of these isolated desert habitats. It is necessary to enlarge the protected area by including several large massifs in several parts of the Fergana Valley. The total area of refuges in this case will be about 95 km2.

Population density of reptiles in four desert areas of southwestern Tajikistan was es- timated in spring 2018–2019. The structure of reptile communities in seven typical landscapes was described. The highest species diversity and population density were observed in sandy landscapes. Seven species of psammobionts formed the basis of these reptile communities. Among them Phrynocephalus interscapularis (56.4), Crossobamon eversmanni (27.8), Eremias lineolata (15.6), Eremias scripta (13.0) had the highest distribution and high population density (individuals/hectare). The relationship of cohabitating species was considered. The highest total population density of reptiles (89.0 ind./ha) was discovered on sandy ridges along the Amu Darya. On the loamy plain the population density of four species was 8.4 ind./ha, and on the foothill plain 2.4 ind./ha. Eremias nigrocellata (2.0 ind./ha) dominated in reptile communities on solid ground. In total, 25 species of reptiles inhabit the desert plains of Southwestern Tajiki- stan. 17 out of 25 (68%) species are included in the national Red Data Book. The level of en- demism and similarity of reptile fauna in desert areas were high. Fauna similarity indices calcu- lated according to Sørensen were 0.9–0.8. These values indicate close contact and connection between desert communities. The formation of the reptile fauna in southwestern Tajikistan oc- curred as a result of dispersal of Turanian species across the left bank of the Amu Darya River from Turkmenistan. They moved to the right bank due to the changes in the riverbed at the Pleistocene Epoch. The absence of some reptile species (Teratoscincus scincus, C. eversmanni, Phrynocephalus mystaceus, E. lineolata, Eremias grammica, E. scripta, etc.) in Northern Af- ghanistan along the border with Tajikistan is explained by the lack of herpetological study of this territory. Their habitat in the area is highly probable. Isolation and autonomy of desert are- as in the Amu Darya valley create the opportunity for formation of new taxonomic forms. Ex- amples are lizards E. scripta ladzinni and P. interscapularis sogdianus. The desert plains of Southwest Tajikistan have a small area and are subjected to significant anthropogenic pressure. Protection of small species, including lizards (Phrynocephalus raddei, P. mystaceus, Varanus griseus) and snakes (Eryx tataricus, Spalerosophis diadema, Boiga trigonatum, Naja oxiana, Echis carinatus) is needed. For widespread and numerous psammobiont species (P. interscapu- laris, E. lineolata, E. grammica, E. scripta, C. eversmanni) there is no threat of extermination at the moment.

Terrestrial route counts of reptiles in 24 localities of the plateau Ustyurt were carried out in 2007 – 2008. 474 individuals of 15 species were found along a total of 243.5 km passed. Based on the results of our survey, the reptile population structure has been clarified in 12 landscapes. The low specific diversity and population density of reptiles were observed everywhere. 2 to 8 species with a population density of 1.9 – 8.4 individuals per ha were found in certain landscapes. In terms of abundance, the reptiles belonged to rare or common species. The steppe agama Trapelus sanguinolentus and the Central Asian tortoise Agrionemys horsfieldii were the most abundant. Four racerunner species (Eremias) had a pronounced confinement to various types of substrate, which allowed them to occupy the dominant position in the landscapes by numbers. Four main landscape complexes of reptile communities were identified, which changed zonally in the latitudinal direction. The attitude of the reptiles to their environmental conditions is discussed. The plasticity of the Eremias species to substrates is estimated, and to distinguish its types is suggested.

The book summarizes studies related to the herpetofauna of Kazakhstan that were carried out in the 18th century. The first fragmentary information on this topic refers to the middle of this century (J.G. Gmelin, P.I. Rychkov). The greatest scientific value were the results of the academic expeditions (P.S. Pallas, I.I. Lepekhin, S.G. Gmelin, J.P. Falk, J.G. Georgi, N.P. Rychkov) between 1768 and 1774, especially the field data obtained by P.S. Pallas. This information served as a basis for the inclusion of data on amphibians and reptiles inhabiting the territories of present-day Kazakhstan (mainly the western Caspian region) into foreign herpetological reviews on a global scale as well as the zoological manuals established by West- European naturalists (e.g., P.L.S. Müller, G.H. Borowski, B.-G.-É. Lacepède, P.-G. Bonnaterre, J.F. Gmelin, F.A. Меyer, J.A. Donndorff, G.A. Suckow, I. Schneider, J.M. Bechstein, W. Тurton). Тhese studies concluded with the first summaries of the herpetofauna of the Russian Empire compiled by J.G. Georgi (1801) as well as by P.S. Pallas in his “Zoographia Rosso-Asiatica” (1814). Short biographies of all mentioned authors are presented in this volume, and annotated lists of species they noted for Kazakhstan as well.

Many regions of the former USSR still re- ceive little attention from Western visitors, herpetologists not excluded. For the Cau- casus Mountains this is all the more sur- prising since the area forms a zone where northern and Middle Eastern flora and fauna meet, and which is thus of considera- bly zoogeographical interest. Presently we find three larger states in the Caucasus: Georgia, Azerbaijan and Arme- nia. Turkey borders to the southwest, Iran to the southeast, and in the north it is the Russian federation. Various smaller parts claim independence. The Black Sea forms the natural western boundary, the Caspian Sea the eastern one. Herpetologically the Caucasus is historically well-known because of the work of Darev- sky and collaborators on the rock lizards (at the time still in the large genus Lacerta, now in Darevskia) and the discovery of the first case of parthenogenesis in vertebrates (DAREVSKY, 1967; DAREVSKII, 1978; DAREVSKY & KULIKOVA, 1961). Below we will concentrate on the results of our field trip to Georgia during the last two weeks of June 2003. Predictably, because of our common interest in the group, the lacertids will receive the most attention.

A phylogenetic-comparative approach was used to assess and refine existing secondary structure models for a frequently studied region of the mitochondrial encoded large subunit (16S) rRNA in two large lizard lineages within the Scincomorpha, namely the Scincidae and the Lacertidae. Potential pairings and mutual information were analyzed to identify site interactions present within each lineage and provide consensus secondary structures. Many of the interactions proposed by previous models were supported, but several refinements were possible. The consensus structures allowed a detailed analysis of rRNA sequence evolution. Phylogenetic trees were inferred from Bayesian analyses of all sites, and the topologies used for maximum likelihood estimation of sequence evolution parameters. Assigning gamma-distributed relative rate categories to all interacting sites that were homologous between lineages revealed substantial differences between helices. In both lineages, sites within helix G2 were mostly conserved, while those within helix E18 evolved rapidly. Clear evidence of substantial site-specific rate variation (covarion-like evolution) was also detected, although this was not strongly associated with specific helices. This study, in conjunction with comparable findings on different, higher-level taxa, supports the ubiquitous nature of site-specific rate variation in this gene and justifies the incorporation of covarion models in phylogenetic inference.

The National University of Mongolia, the Mongolian State University of Education, the University of Nebraska, and the University of Kansas conducted four collaborative expeditions between 2010 and 2014, resulting in accounts for all species of lacertid and agamid, except Phrynocephalus kulagini. These expeditions resulted in a range extension for Eremias arguta and the collection of specimens and tissues across 134 unique localities. In this paper we summarize the species of the Agamidae (Paralaudakia stoliczkana, Ph. hispidus, Ph. helioscopus, and Ph. versicolor) and Lacertidae (E. argus, E. arguta, E. dzungarica, E. multiocellata, E. przewalskii, and E. vermiculata) that were collected during these four expeditions. Further, we provide a summary of all species within these two families in Mongolia. Finally, we discuss issues of Wallacean and Linnaean shortfalls for the herpetofauna of the Mongolian Gobi Desert, and provide future directions for studies of community assemblages and population genetics of reptile species in the region.

From the perspectives of biodiversity conservation and management, there is an urgent need to have at hand current synopses of classification and distributions of species. In this paper, we review and summarize the classifications, Chinese and English names, type specimens, type localities and distributions of China’s lizard fauna to promote scientific exchange and species conservation among relevant people in China and internationally. As of December 31, 2020, a total of 230 species of lizard, belonging to 44 genera and 12 families, have been recorded from China, including 4 invasive species: 2 in the family Gekkonidae, 1 in Iguanidae and one in Dactyloidae. There are 115 endemic species, accounting for 50% of this group. The proportion of endemic species to China was the highest in the family Eublepharidae (84.62%), and the number of endemic species to China was the highest in the family Agamidae (42 species). The species distributions and classification in the “Fauna Sinica (Reptilia 2): Squamata (Lacertilia)” were updated. Among the provincial administrative units, there is a larger number of species in the southern provinces, such as Yunnan, Guangdong, Guangxi and Taiwan. Sichuan, Yunnan, and Taiwan harbour relatively more endemic species than others. A total of 154 species of lizards were first discovered in China, and the type localities of these species are concentrated in Yunnan, Taiwan, Tibet, Xinjiang, and Sichuan.

We discuss three aspects of the thermal biology of lacertid lizards. First, we provide an overview of the available data on field body temperatures (Tb), the thermal sensitivity of various performance functions and selected body temperatures in different species of lacertid lizards. We also briefly summarise information on the mechanisms of thermoregulation. Second, we discuss recent developments to estimate the »precision« of thermoregulation, and the contribution of distinct behavioural mechanisms. Finally, we revise available evidence for the existence of evolutionary adjustments of thermal characteristics in lacertid lizards. Existing studies have mainly dealt with within- and among-species differences in thermoregulatory behaviour (selected temperatures) and thermal physiology of adults (optimal temperatures, heating rates). Available data provide only limited evidence for clear-cut evolutionary shifts in thermal physiology characteristics along climatic gradients.

The disturbance of the thyroid system and elimination of chiral pyrethroid pesticides with respect to enantioselectivity in reptiles have so far received limited attention by research. In this study, bioaccumulation, thyroid gland lesions, thyroid hormone levels, and hypothalamus-pituitary-thyroid axis-related gene expression in male Eremias argus were investigated after three weeks oral administration of lambda-cyhalothrin (LCT) enantiomers. In the lizard liver, the concentration of LCT was negatively correlated with the metabolite-3-phenoxybenzoic acid (PBA) level during 21 days of exposure. (+)-LCT exposure induced a higher thyroid follicular epithelium height than (−)-LCT exposure. The thyroxine levels were increased in both treated groups while only (+)-LCT exposure induced a significant change in the triiodothyronine (T3) level. In addition, the expressions of hypothalamus-pituitary-thyroid axis-related genes including thyroid hormone receptors (trs), deiodinases (dios), uridinediphosphate glucuronosyltransferase (udp), and sulfotransferase (sult) were up-regulated after exposure to the two enantiomers. (+)-LCT treatment resulted in higher expression of trs and (−)-LCT exposure led to greater stimulation of dios in the liver, which indicated PBA-induced antagonism on thyroid hormone receptors and LCT-induced disruption of thyroxine (T4) deiodination. The results suggest the (−)-LCT exposure causes higher residual level in lizard liver while induces less disruption on lizard thyroid activity than (+)-LCT.

Dermal exposure is regarded as a potentially significant but understudied route for pesticides uptake in terrestrial reptiles. In this study, a native Chinese lizard was exposed to control, diflubenzuron or flufenoxuron contaminated soil (1.5 mg kg−1) for 35 days. Tissue distribution, liver lesions, thyroid hormone levels and transcription of most target genes were examined. The half-lives of diflubenzuron and flufenoxuron in the soil were 118.9 and 231.8 days, respectively. The accumulation of flufenoxuron in the liver, brain, kidney, heart, plasma and skin (1.4–35.4 mg kg−1) were higher than that of diflubenzuron (0–1.7 mg kg−1) at all time points. The skin permeability factor of flufenoxuron was more than 20-fold greater than that of diflubenzuron at the end of exposure. However, the liver was more vulnerable in the diflubenzuron exposure group. The alterations of triiodothyronine (T3) and thyroxine (T4) level after diflubenzuron or flufenoxuron exposure were accompanied with the changes in the transcription of target genes involved not only in hypothalamus-pituitary-thyroid (HPT) axis (sult, dio2, trα and udp) but also in metabolism system (cyp1a and ahr). These results indicated that flufenoxuron produced greater body burdens to lizards through dermal exposure, whereas both diflubenzuron and flufenoxuron have the potential to disturb metabolism and thyroid endocrine system.

Lambda-cyhalothrin (LCT) is a widely used pyrethroid with neurotoxicity. However, little is known about the toxicokinetics of LCT in reptiles. In this study, the absorption, distribution, metabolism and excretion of LCT in Chinese lizards (Eremias Argus) were determined following a single dose (10 mg kg−1) treatment. In the liver, brain, gonads and skin, LCT levels peaked within several hours and then decreased rapidly. However, the concentration of LCT gradually increased in the fat tissue. More than 90% of the LCT dose was excreted in the faeces. One LCT metabolite, 3-phenoxybenzoic acid (PBA), was detected in lizard plasma and tissues. PBA preferentially accumulates in the brain and plasma. The half-life of PBA in the brain was 3.2 days, which was 35.4-fold greater than that of LCT. In the plasma, the concentration of PBA was significantly higher than that of LCT. The bioaccumulation of LCT in tissues was enantioselective, and the enantiomeric fractions (EF) ranged from 0.72 to 0.26. The preferential accumulation of enantiomers changed according to exposure time, but the reasons behind this phenomenon were not clear. For pathological analysis, vacuolation of the cytoplasm and large areas of necrosis were observed in the liver sections after 168 h of dosing. The liver tissues exhibited both decreases in the hepatosomatic index and histopathological lesions during the exposure period. In this study, the effect concentration of LCT in lizards was 200-fold lower than its LD50 value used in risk assessments for birds. These results may provide additional information for the risk assessment of LCT for reptiles and indicate that birds may not be an ideal surrogate for reptile toxicity evaluation.

Flufenoxuron is a widely used pesticide to inhibit the synthesis of chitin during insect development and its effect on the growth of lizards has been little addressed. The hypothalamus-pituitary-thyroid (HPT) axis plays an important role on the development of lizards. In this study, the lizards at different development stages (proliferation and resting stages) were exposed to flufenoxuron for 21 days. The plasma thyroid hormone levels, thyroid gland histopathology and expression profiles of thyroid hormone receptors (trα, trβ), deiodinases (dio1, dio2), and transthyretin (ttr) genes were measured to evaluated the toxic effect of flufenoxuron on the HPT axis at different stages. The flufenoxuron exposure showed more seriously effect on the triiodothyronine (T3) level at resting phase than that at proliferation stage. The follicle epithelium cell height in the thyroid was only significantly increased when the exposed male lizards were at proliferation stage. The alteration of HPT axis-related genes expression was gender and tissue dependent after flufenoxuron treatment. The lizards exposed to flufenoxuron showed that the trα, trβ, dio1, dio2, and ttr genes in the female liver were more sensitive at the proliferation stage than that at the resting stage. In the male brain, the expressions of trα, trβ, dio1, and dio2 gene were significant decreased at proliferation stage while significant increased at resting stage after flufenoxuron exposure. Therefore, the thyroid endocrine system of lizards could be affected by the flufenoxuron exposure and the different development stage should also be considered when study the toxic effect of contaminants on the lizards.

More and more studies are focusing on toxic effect of pesticides on lizards. However, the responses of different life-stage lizards to pesticides have not been reported. In this study, according to RNA-seq library data, thyroxine 5′-deiodinase activity showed significant difference between mature and immature lizard liver. In addition, triiodothyronine (T3) level in immature lizard serum was higher than that in mature lizard serum. Thus, we investigated the thyroid disruption of flufenoxuron with different concentrations (0, 5, 20 mg/kg) to both mature lizards and their offspring. No significant differences were observed in immature lizard body weight compared between control and exposure groups while the body weight of mature lizards was significantly decreased after flufenoxuron exposure. Moreover, the levels of thyroid hormones and the expression of thyroid related genes changed with exposure concentration of flufenoxuron and exhibited different regulation mechanism between mature and immature lizards. In immature lizard liver, trα, trβ, dio1 and ugt genes controlled the thyroid hormone levels interfered by flufenoxuron. In contrast, the thyroxine (T4) pathway in mature lizard liver was significantly disrupted especially by 20 mg/kg flufenoxuron exposure. This study elucidated the different thyroid disruption effects of flufenoxuron to lizards based on different exposure doses and lizard life stages.

Benzoylurea pesticides (BPUs) are widely used to control the locust, but the toxicokinetics and hepatotoxicity of BPUs in lizards have not been investigated. In this study, the tissue distribution, metabolism and liver toxicity of diflubenzuron and flufenoxuron were assessed in the Eremias argus following a single oral exposure. Diflubenzuron preferred to accumulate in the fat and brain (>1.0 mg kg−1) and was rapidly eliminate in other tissues. In the liver, 4-chloroaniline was one of diflubenzuron metabolites, although with a concentration less than 0.05% of the accumulated diflubenzuron. No significant difference was observed in the liver histopathology between the control and diflubenzuron exposure group. The expressions of Cyp1a and Ahr gene which control the cell apoptosis were also equal to the control level. After flufenoxuron exposure, biomodal phenomenon was observed in the liver, skin, brain, gonad, kidney, heart and blood circulation was an important route for the flufenoxuron penetration. The concentrations of flufenoxuron in all tissues were greater than 1.0 mg kg−1 at 168 h. The excretion of flufenoxuron in the faeces was 1.5 fold higher than diflubenzuron. The hepatocytes in the flufenoxuron treated group showed vacuolation of cytoplasm and decreased nucleus. In addition, the Cyp1a and Ahr genes were significantly up-regulated in the flufenoxuron exposure group. These results suggested that the higher hepatotoxicity of flufenoxuron may be attributed to the higher residual level in the lizard tissues and the Cyp1a and Ahr genes can serve as biomarkers to assess the liver toxicity.

Reptiles are sensitive to temperature changes as ectotherm animals. The climate warming may pose more serious threat to reptiles. Although the behavior effect and reproduction biology have been well studied, little information is available about the adaptation mechanisms of reptiles to temperature stress. In this study, the native Chinese species, Eremias argus were incubated at 15 (cold stress), 25 (control group) and 35 C (thermal stress) for 24 h. The transcriptome and metabolome technology were applied to investigate the molecular regulation mechanisms of lizards to acute temperature changes. The CIRBP and HSPA8 were hub genes in response to temperature adaptation. The increased expression of PER gene in lizard circadian rhythm is associated with tyrosine metabolism after cold or thermal stress. The poly-unsaturated fatty acids in female lizard liver were significantly increased with up-regulation of FASN and ACACA genes after thermal stress, which proved the disruption of fatty acid biosynthesis pathway in corporation with the altered body weight. The cortisol and testosterone were important steroid hormones in response to temperature changes especially in male lizard liver. The increased CIRBP gene expression in lizard gonads suppressed the KDM6B gene, which regulates the testis development and may induce sex reversal in male lizard after thermal stress. The adaptation responses of lizards to temperature stress may threaten the health status of wild population.

Although the thyroid effects of pyrethroids on non-target organisms have been well studied, research on the toxic effects of pyrethorid metabolites is still limited. In this study, a type of representative Chinese lizards was used as the model and exposed to environmentally relevant concentrations of lambda-cyhalothrin (LCT) and 3-phenoxybenzoic acid (PBA) through cultivation on 3 and 15 μg/g soil to evaluate and compare their disruption effects on lizard hypothalamus-pituitary-thyroid (HPT) axis. The alterations occurred in lizards were examined through histopathology analyses, hormone level and gene expression measurements, the molecular binding interactions were analyzed in silico as well. The results showed that LCT exposure increased the plasma triiodothyronine (T3), thyroxine (T4) levels and the follicular epithelium heights of thyroid glands, whereas PBA induced no or much less degree of alterations. The ugt and dio2 gene expression in lizard liver was significantly up-regulated by LCT, but PBA caused less or opposite effects. The in silico homology simulation illustrated that LCT binds to TRα in the similar way of T3, while PBA binds to TRβ in the same manner of T3. The results demonstrated that both LCT and its metabolite-PBA could disrupt lizard HPT axis but through distinct mechanisms. The information would facilitate the comprehensive environmental safety assessment of pyrethroids.

Diflubenzuron (DFB) is a potential endocrine-disrupting chemical. However, its thyroid endocrine effect on reptiles has not been reported. In this study, immature lizards (Eremias argus) were exposed to 20 mg kg−1 DFB once a week for 42 days through oral or dermal routes. Their body weight, plasma thyroid hormone levels, thyroid gland histology and the transcription of hypothalamic–pituitary–thyroid (HPT) axis-related genes in different tissues were assessed to explore the effects of DFB on the HPT axis of lizards. The body weight decreased significantly only after the dermal exposure to DFB. Triiodothyronine (T3) to thyroxine (T4) ratio in the male plasma also significantly increased after the dermal exposure. After oral exposure, the activity of thyroid gland was positively related to the thyroid hormone levels. Furthermore, the alterations in thyroid hormone levels affected the HPT axis-related gene expression, which was tissue dependent and sexually selected. The thyroid hormone receptor genes (trα and trβ) in the brain and thyroid were more sensitive to oral exposure. However, only the dermal treatment affected the trα, trβ and type 2 deiodinase (dio2) genes in the male liver. These results suggest that DFB exposure caused sex-specific changes in the thyroid function of lizards, and the dermal treatment may be an important route for the risk assessment of reptiles.

In this study, the different metabolic pathways of lambda-cyhalothrin (LCT) enantiomers in Eremias argus feces and enantioselective disruption on hypothalamus-pituitary-gonad (HPG) system were investigated. After 7 days oral exposure to LCT enantiomers, the concentration of 3-phenoxybenzoic acid (PBA), hydroxylated and sulfated LCT were higher in the (+)-LCT exposure group than that in the (−)-LCT exposure group, which indicated a higher metabolic rate of (+)-LCT than (−)-LCT. Although no significant differences were seen on lizard body weight after enantiomers’ exposure, the gonadosomatic index was dramatically decreased. The testicular impacts such as increased seminiferous tubule diameters were only observed in the (+)-LCT exposure group. Consistent with this result, the expression of ar gene in the (+)-LCT exposure was significantly higher than that in the (−)-LCT exposure group. In addition, the stronger binding affinity of AR with (+)-LCT further demonstrated the more serious disruption of (+)-LCT on lizard HPG axis than (−)-LCT. This study first elucidated the metabolic pathway and endocrine effects of LCT in lizards at enantiomeric level and provided some evidence for lizard population decline.

This study was conducted to find the sexual size dimorphism(SSD) in morphometric characters of three species , Eremias argus, Takydromus amurensis and T. wolteri in lacertid lizard from Korea. Six external traits, snout‐vent length, tail length, head length, head width, forelimb length and hind-limb length were focused to compare two sexes among the each three lizards. Student`s t‐test was used to compare the adult SVL between the sexes for each species. For the other parts of the body, a one‐way analysis of covariance(ANCOVA) with SVL as the covariate was used. In all these species, males have longer tail and head than females like general lacertid lizard. In addition, male E. arugus have broader head and longer forelimbs and hind-limbs than conspecific females. Likewise, male T. wolteri have broader head than females. In the three lacertid lizards from Korea, snout‐vent length did not significantly differ between the sexes. To understand the causes for SSD in SVL, ecological information, such as the presence/absence of male-male combat and the correlation between the SVL of female and litter size, is required. Therefore, further ecological study on the three species of lacertid lizard from Korea will make it possible to explain the reason SSD is not found in SVL.

The endangered species Mongolian racerunner (Eremias Argus), with a limited distribution in South Korea, is found only in sanddunes near waterside and forests. Therefore, species trends in this particular habitat are directly affected by habitat contaminationand destruction. In this study, we examined the effects of coastal sand dune restoration on the distribution and population ofE. argus. We conducted a field survey in Baramarye special protection zone, called Baramarye Coast, a part of the TaeanhaeanNational Park, during April and June 2016. We searched and recorded the location ofE. argusand tagged them using the toeclipping method. The size of theE. arguspopulation was estimated using the Peterson method. After the restoration of coastalsand dunes in Baramarye Coast, the population size ofE. argusincreased by 126–137 (21.1–55.7%) compared with that in 2008.The home range ofE. argusin coastal sand dunes was significantly expanded by 4.8-fold for 95% Kernel density (KD) and 3.6-fold for 50% KD compared with that in 2008. Moreover, we confirmed that the distribution ofE. arguswas expanded to therestored area. Our study showed that in situ conservation is effective for endangeredE. argus,distributed in particular environ-ments such as coastal region. This study provides one more reason why coastal region must be conserved.

The Variegated Racerunner, Eremias vermiculata, is widespread in Northwest China, southern Mongolia, and Zaisan Basin of Kazakhstan. In this study, a nearly complete mitochondrial genome (17,972 bp in length) of E. vermiculata from the Dunhuang Basin in Northwest China was determined by next-generation sequencing. Similar to the typical mtDNA of vertebrates, it contained two ribosomal RNA genes, 13 protein-coding genes (PCGs), 22 transfer RNA genes, and one control region (CR). With exception to the CR, all of the 37 genes were completely recovered. The concatenated PCGs were used to conduct Bayesian phylogenetic analyses together with mitogenome data of lacertids in GenBank. The resulting phylogenetic tree confirmed the monophyly of genus Eremias and its viviparous species as well as E. vermiculata, respectively. The mitogenome presented here will contribute to the examination of phylogeographic structure for E. vermiculata and understanding of mitochondrial DNA evolution in Eremias.

Numerous studies suggested that reptiles are sensitive to environmental pollution and the abundance of many species are in decline. Our research is aim to assess the toxic effects of pesticide in reptiles. And we also want to supply some data about nondestructive samples for environmental risk assessment in reptiles. Lizards were orally administered a single-dose of beta-cypermethrin (BCP) or myclobutanil (MC) at the concentration of 20 mg/kg body weight (bw). The results showed that pesticides could induce changes in enzymatic activities (SOD, CAT, LDH, AChE) and MDA levels in organs or tissues of lizards. BCP could cause more severe oxidative damage than that of MC. Salivary enzymes activities showed sensitivity changes to the toxicity of pesticides. We could use saliva to reflect whether the reptiles are toxic by pesticides. We also agree that buccal swabs could be used as a tool for saliva sampling.

Eleven polymorphic microsatellite loci are described for the multi-ocellated racerunner Eremias multiocellata (Squamata: Lacertidae). Loci were screened in 33 individuals of E. multiocellata. The number of alleles ranged from 11 to 17. The observed heterozygosity ranged from 0.515 to 0.939, and the expected heterozygosity from 0.875 to 0.925. These microsatellite markers provide a valuable set of tools for population genetic studies of E. multiocellata.

In recent years, serious environmental pollution has caused a decrease in the abundance of many species worldwide. Reptiles are the most diverse group of terrestrial vertebrates. There are large amounts of toxicological data available regarding myclobutanil, but the adverse effects of myclobutanil on lizards has not been widely reported. In this study, treatment groups were orally administered a single-dose of myclobutanil (20mg/kg body weight (bw)). Subsequently, it was found that there were differences in myclobutanil levels between the different tissues and concentrations also changed with degradation time. The tissue concentrations of myclobutanil decreased in the order of: stomach > liver > lung > blood > testis > kidney > heart > brain. Based on our results, the liver and testis were considered to be the main target organs in lizards, indicating that the myclobutanil could induce potential hepatic and reproductive toxicity on lizards. Meanwhile, it was also demonstrated that the toxic effects of myclobutanil was different in different species, and the distribution of different pesticides in lizards were different.

Soil contamination caused by the widespread use of pesticides is one of the main environmental problems facing conservation organizations. (S)-metolachlor (SM) is a selective pre-emergent herbicide that poses potential risks to soil-related organisms such as reptiles. The present study elucidated the toxic effects of SM (3 and 30 mg/kg soil weight) in Eremias argus. The results showed that growth pattern was similar between the sexes in breeding season. For males, both kidney coefficient (KC) and testis coefficient in the exposure group were significantly different from those in the control group, while only KC in the high-dose group was significantly higher for females. Based on histopathological analysis, the livers of female lizards were more vulnerable than those of males in the exposure group. A reduction in total egg output was observed in SM exposed lizards. Accumulation studies indicated that skin exposure may be an important route for SM uptake in E. argus, and that the liver and lung have strong detoxification abilities. In addition, the body burdens of the lizards increased with increasing SM concentration in the soil.

Beta-cypermethrin (BCYP), a synthetic pyrethriod (PYR) pesticide which is a mixture of the alpha- and theta- cypermethrin, have been reported various toxicological profiles to non-target organisms. But little is known about assimilation, accumulation and toxic effects of BCYP in reptiles. The present study firstly elucidated absorption, tissue distribution, excretion of BCYP in Eremias argus . Treated group were administered orally with BCYP 20 mg/kg body weight (bw) dissolved in corn oil. Neurotoxicity was observed at 24 h after gavage, and the poisoning symptom ameliorated at 72 h. The changes of BCYP concentration depended on degradation time and tissues. Lizards had a strong capacity to eliminate BCYP with different tissue distribution. The tissues concentration of BCYP from high to low were intestine, stomach, heart, kidney, blood, lung, liver and brain. Bimodal phenomena were observed in lung, liver and kidney. These results may be due to the activities of enzymes, circadian rhythm, and enterohepatic circulation in lizards. Based on the results of organ coefficient and histopathology analysis in liver, the liver was confirmed as the main target organ.

Variants of estimating the number of different lizard species in natural populations are proposed. In one sense or another, we are talking about an accounting site of a known area. But depending on the biological features of different lizard species, the accounting indicators may be different: either it is a fixation of the total number of lizards living on the accounting site (which is possible for the toad-headed agama Phrynocephalus mystaceus), or it is a fixation of the number of lizards encounters on accounting routes of a certain length and width, i.e. a certain area (which is possible for the steppe runner Eremias arguta). Correction coefficients should be introduced into the accounting results, which should take into account that: 1) the distribution of lizards across the territory is uneven due to microbiotopic differences (K1), 2) not all lizards that live in the this territory may be active on the surface every day (K2), 3) when using different registration methods, primary accounting data allow registering a different proportions of lizards from their total number inhabiting this site (K3). After such an adjustment of the accounting results, it is possible to calculate the density of lizard settlements and the absolute number of lizards for any separate sections of entire territories. As a result of our work, we have so far determined the composition of these coefficients. Subsequent studies should lead to the development of standardized methods for determining these coefficients. According to our calculations, the density of the population of toad-headed agamas in the area of their most compact habitat on the large Sarykum dune can be up to 125 individuals/ha, and their total number can be estimated at about 7000-7500 individuals. For steppe runners, their population density in places of compact habitat in the vicinity of the small Sarykum dune can be 18.0-23.4 ind./ha, and their total number in the area of about 9 ha, where we carried out our research work, could be 180-220 individuals. By standardizing the methods of evaluating different species of lizards, it is possible to organize correct long-term monitoring of the state of their populations.

Background. The reptilian thermobiology is the most important factor determining their ecology, spatial and temporal structure of activity and biotopical distribution. But the mechanisms of this process are poorly understood. This article describes the results of studies illustrating the specific mechanisms of the influence of certain thermophysiological characteristics and characteristics of thermoregulation in two sympatric species of racerunners on their ecology and their biotopical selection in Kyzylkum desert. Materials and methods. In the Kyzylkum desert we studied the thermophysiological characteristics of the full activity and temperature stabilization ranges, as well as the thermoregulation techniques in two species of racerunners. Also, in this area we studied the climatic conditions in different biotopes. All the data obtained were associated with observations of the spatial and temporal structure of the daily activity of lizards and their biotopical preferences. Results. The aralo-caspian racerunner is noticeably less thermophilic in thermobiological indicators than the striped racerunner. The temperatures of full activity in the aralo-caspian racerunner are 32,3–39,0º, the range of temperature stabilization is 34,0–35,5º. In the striped racerunner, these indicators are 34,5–41,0º and 35,5–37,0º, respectively. For some morphological and physiological reasons, under the same conditions, the body in aralo-caspian racerunner heats up faster than in striped racerunner. Striped racerunners, unlike aralo-caspian ones, can actively use the lower branches of bushes for thermoregulation, i.e. to separate their body from the hot soil during the warmest part of day. Conclusions. The thermobiological characters and the manner of thermoregulation lead to differences in the spatial-temporal activity structure and biotopical differences between aralo-caspian and striped racerunners: the striped racerunners have the ability to use and actually use more open spaces for activity and a hotter time of day, while aralo-caspian ones use more matted areas with openwork or dense shadow, with shrubs and trees, and are active at more fresh time of day.

Sexual dimorphism, age and geographical variability of 254 specimens of Eremias velox from 20 localities of Kazakhstan and Uzbekistan were studied. Sexual dimorphism found to be clearly manifested in some metric characters, amount of abdominal shields and peculiarities of preanal region pholidosis. It is suggested to use males for the examining of ecological relations, as they demonstrate more adaptive peculiarities of given characters, whereas females are more suitable for phylogenetic analysis. Some peculiarities of age variability are demonstrated. Cline variability is shown from west to east for the following characters: body length, head length, head width, rear limb length. The rate of cline variability is less in Alakol Depression. Females, however, demonstrated the decreasing of body length meaning from west to east. The largest body size in South-East Kzyl-Kum population suggesting, probably, that the most favorable conditions for this species is located in the region mentioned. Contrary, the conditions in the Alakol Depression are less favorable. Variations of coloration are described for E. velox. It is shown that the specter of head pholidosis is distinct from other species within Eremias genus, having 1-7 scales in between of parietal and interparietal shields. Eastern Kazakhstan populations are distinct from others by several characters, including peculiarities of pholidosis.

407 specimens of Eremias arguta, 140 specimens of E. intermedia and 271 specimens of E. velox from Kazakhstan and adjacent areas were examined in respect of pholidosis variability. 24 pholidosis characters of head and preanal region and 2 pholidosis characters of rear limbs were analyzed. Resulting from analysis, we divide E. arguta into three main groups. First group comprises animals from Volgograd District (Russia) and, partially, animals from Western Kazakhstan. Second group includes the rest of Western Kazakhstan samples, North Aral Sea Region, Eastern Kazakhstan and some specimens from Semirechje. Specimens from Kzylkum sands, Karatau ridge and environs of Kopa station were referred to as third group. The rate of specimens with increased amount of shields before the 2nd supraocular shield trends to gradual grow westward and southward. E. intermedia shows no significant differences within range of species distribution in Kazakhstan. Most variable E. velox from Western Kazakhstan are characterized with absente or only single scute between frontal and supraocular shields. Most variable temporal region were documented for eastern samples.

In present work the data on morphological variability of the Stepperunner from 6 populations of the Aral Sea Basin are resulted. Data analysis has shown that the lizards from the northern regions of Aral Sea Basin reliably differ from those inhabited the southwestern regions in length and width of a head, attitude of head length to length of a trunk, length of hind limb and its attitude to trunk length, number of scales around 9-10 tail segments and pattern of coloration.

77 specimens of the Sand Racerrunner, Eremias scripta (Strauch, 1867) from 5 populations of Kazakhstan were studied and compared in respect of 9 metric and 6 pholidosis characters. The differences between the lizards from Aral Sea Basin and Balkhash Lake Basin regions have been shown in number of scales around body (Sq), scales around 9-10 tail rings (SQCD) and color pattern. The differences in number of SQCD and color pattern were also revealed between the specimens from the sands of South Balkhash Region and isolated Barmakkum Sands in Alakol Depression.

Phenotypic traits are usually correlated with the environment where organism occurs. In this study, the distribution of Eremias velox in the eastern periphery of its range was specified, and its morphological variation was analyzed. Linear dimensions, pholidosis, coloration and pattern features were compared among 135 specimens from nine populations inhabiting the Balkhash, Ili and Alakol basins, Junggar and Turpan depressions in the territory of Southeast Kazakhstan and Xinjiang, Northwest China. The populations from the Junggar Depression (Kuytun, Shihezi and Urumqi) were characterized by higher mean values of linear characters, the number of scales across the middle of the body and gular, and were similar in the dominant coloration patterns. Small size, dark coloration and almost complete dominance of the striped-type coloration pattern among the specimens from the Alakol Lake islands seem to have an adaptive significance associated with the isolation of the population and type of their habitats. The subspecies Eremias velox roborowskii (endemic to the Turpan Depression) is elevated to species level, as supported by morphological divergence congruent with molecular and geographical data, including its peculiar type of coloration pattern, significantly lower amount of femoral pores and a higher percentage of specimens with one enlarged preanal scale (72.7%). These results together confirm a high degree of variability in morphology for E. veloх in the eastern periphery of its range, reflecting a complex orography and the existence of multiple geographical barriers in this territory.

Morphology and subspecies of Eremias arguta (PALLAS, 1773), in Kazakhstan. The external morphology of Eremias arguta in Kazakhstan was examined. Three metric and ten meristic characters as well as the dorsal pattern of 206 individuals from 13 populations of southern, south-eastern and eastern Kazakhstan were analyzed. Sexual dimorphism was found to occur in relative tail length (fem. > males), number of longitudinal gular scales (fem. < males), and number of femoral pores (fem. < males). Clinal variation exists in the number of dorsals, gulars, femoral pores, and scales between femoral pores. Most of populations studied revealed a pattern of large white spots and transverse dark strips. Some specimens from eastern Kazakhstan are characterized by small white spots and interrupted, somewhat fused dark strips. Most southern populations show elongated white spots and irregular black spots scattered along the dorsum. Subspecies status of the steppe-runners from eastern Kazakhstan is still unclear and needs future clarification. Populations from south-eastern Kazakhstan are closer to E. arguta potanini. Southernmost populations belong to E. a. uzbekistanica.

The ecological-niche models for two sympatric species, Eremias lineolata (Nikolsky, 1897) and Eremias scripta (Strauch, 1867), reveal evidence of spatial and temporal disjunction in the actual niches of both species. Eremias lineolata demonstrates a wide range of adaptations and, at the same time, has a greater need for winter precipitation and minimal temperature than E. scripta. Possible explanations for the thermal diversity of both species are provided. Thermal variables (monthly temperatures, monthly solar radiation, etc.) are traditionally important for ectotherm animals. Interestingly, as many as half of the key variables in both species are related to different aspects of environmental water balance (precipitation, air humidity, vapor pressure). There are several ways in which moisture may impact the lizard’s life cycle. Soil humidity is related to soil temperature and may be important during winter hibernation. In summer, soil humidity may support successful embryogenesis. Precipitation during the warm months is a key factor in maintaining the moisture content of the soil. In winter, snow cover provides a better thermal balance of the soil’s top layers where winter shelters are housed. Ecological niche modeling (ENM) is an interdisciplinary approach combining the geographical, climatic, ecological, and biological aspects of the wellbeing of species. This interdisciplinary approach lifts biological studies onto a new, integrative level, providing a comprehensive view on species biology and answering the questions that might not be answered if the traditional methods for studying animals were used alone.

e reptile fauna of Romania comprises 23 species, out of which 12 species reach here the limit of their geographic range. We compiled and updated a national database of the reptile species occurrences from a variety of sources including our own eld surveys, personal communication from specialists, museum collections and the scienti c literature. e occurrence records were georeferenced and stored in a geoda- tabase for additional analysis of their spatial patterns. e spatial analysis revealed a biased sampling e ort concentrated in various protected areas, and de cient in the vast agricultural areas of the southern part of Romania. e patterns of species richness showed a higher number of species in the warmer and drier regions, and a relatively low number of species in the rest of the country. Our database provides a starting point for further analyses, and represents a reliable tool for drafting conservation plans.

In Dobrudja we encountered 10 species of amphibians (Triturus dobrogicus, Bombina bombina, Hyla arborea, Pelobates fuscus, Pelobates syriacus, Bufo bufo, Bufo viridis, Rana dalmatina, Rana ridibunda, Rana lessonae), 16 species of reptiles (Emys orbicularis, Testudo graeca, Ablepharus kitaibelli, Lacerta agilis, Lacerta viridis, Lacerta trilineata, Podarcis taurica, Podarcis muralis, Eremias arguta, Coronella austriaca, Zamensis longissimus, Elaphe quatuorlineata, Dolichophis caspius, Natrix natrix, Natrix tessellata, Vipera ammodytes) and also Rana kl. esculenta populations. Some species of amphibians (Pelobates fuscus, Pelobates syriacus) that were only previously known inform the lower regions of the Danube’s meadow and in the vicinity of the Black Sea, were recorded in the high areas of northern Dobrudja. Also here, all three forms of the green frogs’ complex documented for Romania have been encountered, but Rana lessonae and Rana esculenta are very rare, being found only in the north. The central sectors of Dobrudja are severely impacted by human activities, almost completely cleared as a result of agriculture and showed very low number of herpetofauna species as being present. The most important areas for the herpetofauna are the northern and south-western regions.

This paper analyzed the morphological differences among the 8 Eremias species distributed in China.258 specimens were collected and measured.15 countable characters were selected to principal component analysis of data reduction.Based on the loudings of the first three principal components, scatterplots were figured out for further analysis.The results showed that 8 species located in three different regions in the scatterplots.They were E. argus species group (E. argus and E. brenchleyi), E. velox species group (E. velox and E. vermiculata), and E. multiocellata species group (E. multiocellata, E. arguta, E. przewalskii and E. grammica).The main differences between E. argus species group and other two species groups were presented on fn、pfa、scc、nvll and fprs, and it indicated that E. argus and E. brenchleyi were distinctly different from other species of Eremias.E. velox species group could be distinguished from E. multiocellata species group mainly by the character vbfp.The character pfa was found unstable in E. argus, and in 107 specimens there are five types on the numbers of prefrontal and most of them have 4 prefrontals.This article suggested that the character of prefrontal in E. argus was in the stage of intensive evolution, which indicated the formatting of new subspecies of E. argus.This research also agreed that E. quadrifrons Strauch (1876) was an invalid species.The character sisl could be used to distinguish E. argus from E. brenchleyi, which was regarded as a valid species and this character was treated as the difference to classify different species.E. velox and E. vermiculata could be easily distinguished by the characters nvll and clov.The character oa indicated E. grammica should be a group independent among all 8 species.The research showed that the difference between E. m. yarkandensis and E. m. multiocellata was sisl and larger than the differences in E. m. multiocellata、E. arguta and E. przewalskii.We speculated that E. m. yarkandensis should be a valid species but not a subspecies of E. multiocellata.E. m. multiocellata and E. przewalskii were so similar that it was difficult to distinguish them by morphological countable characters.We doubted the validity of the E. przewalskii.Finally based on the results of this research, 8 species were divided into four species groups: E. argus group (E. argus and E. brenchleyi), E. velox group (E. velox and E. vermiculata), E. multiocellata group (E. multiocellata, E. arguta and E. przewalskii), and E. grammica group.

Based on the Giemsa-dyeing karyotypes and silver-staining bands of 15 populations from different localities in China belonging to 6 species of the genus Eremias , We found all species studied have 19 pairs of chromosomes, the size of chromosomes reduces gradually and there are no marked differences between the arranged pairs of macrochromosomes except the last pair of microchromosome. There are the same karyotype formula as 2n=38=36I+2m with NF=38 in E. argus, E. multiocellata, E. velox, E. arguta and E. grammica; but the karyotype formula of E. vermiculata is different as 2n=38=12V+2sI+22I+2m with NF=50. The NOR are all located on one small pair in female of E. velox, and E. arguta , in male of E. grammica and E. vermiculata ,and in both male and female of E. multiocellata. We have not found two or more than two pairs of NOR. Having one pair of NOR may be common in Genus Eremias and also the trait of Eremias. We speculate that the derivation of the karyotype of E. vermiculata had two possible way: one experienced the stage of triploid, and later the Robertsonian transposal of chromosomes; the other way was through the inversions between the arms on the chromosome and the phenomenon of inversions might occur during or subsequently after the upheaval of the Tibet and Qinghai plateau and the founding of the Tianshan . With regard to the trend of the evolution of chromosomes in the lizards ([1]), the karyotype of E. vermiculata is more advanced. Making specialties of E. vermiculata will help in building the phylogenic tree of Eremias. In both male and female of the species studied, the heteromorphic sex-chromosomes were not found.

The reptile and mammals fauna of North-East of Iran were investigated and the contraction and fragmentation of some species due to climatic changes and human activities were analyzed. The sampling was carried out in selected stations throughout the Great Khorsan. The results showed that there are approximately 71 reptiles (including 39 species of lizards, 32 snakes and one turtle) and 83 species of mammals. The exact number of vulnerable and threatened reptile and mammal species in Khorasan provinces is not clear, but there are at least 33 reptiles and 10 mammals categorized as threatened species. The distribution and population size of some species has greatly changed during recent years, most probably as a result of recent global warming, i. e. temperature rise, decrease of precipitation, drought and human harmful activities. The human activity in this region, especially urbanization, agricultural activities and cutting of shrubs has caused fragmentation and serious decline of population size in some species and even elimination of some local endemic population of relict species. The conservation of mammals and reptiles in the North-East of Iran demands organized collaborations including education of native people for protection of valuable vertebrate faunae of the area.

The evolution of body size, both within and between species, has been long predicted to be influenced by multifarious environmental factors. However, the specific drivers of body size variation have remained difficult to understand because of the wide range of proximate factors that consistently covary with ectotherm body sizes across populations with varying local environmental conditions. Here, we used a widely distributed lizard (Eremias argus) collected from different populations situated across China to assess how climatic conditions and/or available resources at different altitudes shape the geographical patterns of lizard body size across populations. We used body size data from locations differing in altitudes across China to construct linear mixed models to test the relationship between lizard body size and ecological and climate conditions across altitudes. Lizard populations showed significant differences in body size across altitudes. Furthermore, we found that variation in body size among populations was also explained by climatic and seasonal changes along the altitudinal gradient. Specifically, body size decreased with colder and drier environmental conditions at high altitudes, resulting in a reversal of Bergmann’s rule. Limited resources at high altitudes, as measured by net primary productivity, may also constrain body size. Therefore, our study demonstrates that the intraspecific variation in female lizards’ body size may be strongly influenced by multifarious local environments as adaptive plasticity for female organisms to possibly maximise reproductive ecology along geographic clines.

Identifying how reproductive strategies such as the trade-off between clutch size versus egg mass vary with elevational gradients is essential for our understanding of life-history evolution. We studied lacertid lizards (Eremias argus) in China, from six populations at different altitudes, to assess elevational variation in reproductive strategy. We found significant between-population variation in maternal body size and clutch mass, but these variations were not explained by elevational differences. However, high-elevation females tended to produce smaller clutches of larger eggs compared with their low-elevation counterparts, demonstrating an elevational change in the trade-off between egg size and number. The egg size-number trade-off is a reproductive strategy that may favor large offspring, better enabling them to survive severe and unpredictable environments found at high elevations.

The evolution of body size within and among species is predicted to be influenced by multifarious environmental factors. However, the specific drivers of body size variation have remained difficult to understand because of the wide range of proximate factors that covary with ectotherm body sizes across populations with varying local environmental conditions. Here, we used female Eremias argus lizards collected from different populations across their wide range in China, and constructed linear mixed models to assess how climatic conditions and/or available resources at different altitudes shape the geographical patterns of lizard body size across altitude. Lizard populations showed significant differences in body size across altitudes. Furthermore, we found that climatic and seasonal changes along the altitudinal gradient also explained variations in body size among populations. Specifically, body size decreased with colder and drier environmental conditions at high altitudes, reversing Bergmann`s rule. Limited resources at high altitudes, measured by the low vegetative index, may also constrain body size. Therefore, our study demonstrates that multifarious environmental factors could strongly influence the intraspecific variation in organisms` body size.

The effects of the degree of urbanization on the composition and mean abundance of helminth species and the structure of helminth communities in the Mongolian racerunner were investigated along a rural–urban gradient in the region of Ulan-Ude city (the Republic of Buryatia, Russia) and neighbouring rural districts. Racerunners were obtained from key areas and categorized into three grades based on the degree of urbanization. In this study, a total of 208 lizards were examined. The helminth communities in the Mongolian racerunner were studied at the infracommunity and component community levels. The nematode Spauligodon pseudoeremiasi was a sensitive bioindicator of the degree of urbanization in our study. All parameters of helminth infracommunities in the Mongolian racerunner were significantly reduced with increasing degree of urbanization of the key areas. Two parameters of helminth component communities (the proportion of hosts infected with parasites and the Shannon index) were significantly reduced with increasing degree of urbanization. The decline recorded in parameters of helminth infracommunities and component communities in the Mongolian racerunner were probably connected with the attenuation of the relationships between helminths, having a complex life cycle with intermediate hosts along the rural–urban gradient.

New finds of the lizards of Eremias multiocellata complex became known for extreme southeast of Kazakhstan. In 2006-2007 re recorded the lizards in the mountain valleys of Kegen and Tekes Rivers creossing an intermountain depression located between Ketmen’ and Terskey-Alatau at altitude 1850-1950 m a.s.l. Morphological analysis revealed the reliable differences of the specimens collected from other species of multiocellata complex inhabited the close areas – E. stummeri from Issyk-Kul’ Depression and E. kokshaaliensis from Sary-Dzhaz River Basin of Kyrgyzstan. Morphological peculiarity of the populations recorded may be caused by their isolative position in extreme southeast of Kazakhstan and needs future elucidation.

The paper presents data on the histology and ultrastructure of the liver of two lizard species, Lacerta agilis and Eremias arguta, inhabiting the territory of the former Semipalatinsk Test Site (Eastern Kazakhstan). An LM study has shown the presence of pathological changes expressed in irregular vascular filling of the liver and venous, local discomplexation of hepatocyte, vacuole and adipose dystrophies and an increase of the local micronecroses where the lymphocyte, resident macrophage and Kupffer cell infiltrations have been registered. An EM investigation has revealed the features of glycogenolysis and decreasing of the lipid embeddings, the phenomenon of hydropical dystrophy and intracellular swelling in the certain part of the hepatocytes, significant hemosiderin accumulations in the liver cells appeared because of intensified catabolism of the phagocyted erythrocytes. The high level of metabolism processes was provided by utilization of the lipid embeddings, the high level of nucleoprotein synthesis and intensification of phosphorylating function of the mitochondria. The functional activity of Kupfer’s hyperplastic cells was directed to the synthesis of pigment granules, the mostimportant role among which belongs to melanin as a strong antioxidant protecting the body against free radicals.

The distribution and habitat characteristics of two Eremias species (E. arguta and E. stummeri) from contiguous areas of southeastern Kazakhstan, northeastern Kyrgyzstan, and western Xinjiang, China, were analyzed using GIS modeling. We show that both species are dry-steppe-adapted xerophilous lizards with sclerophilic and partially petrophilic specialization. In spite of the visible similarity of the ecological niches (ENs) occupied by E. arguta and E. stummeri, the latter differs in a number of key variables. While most of the precipitation variables, the radiation of the winter and off-season months, and afternoon (PM) humidity are most important for E. arguta habitats, the habitats suitable for E. stummeri are limited by temperature variables, radiation during most of the year, and morning (AM) humidity. Differences on this scale indicate the way in which these lizards are adapted to different ecosystems — E. arguta to the plains and E. stummeri to the mountains — and support the views on their different zoogeographical accessory. Avisible correspondence of the distributional pattern of the two Eremias species to the mountain piedmonts and low foothills, with Pliocene-Quaternary concreted pebble deposits and the loess strata, permit us to consider mountain trails as the most likely means by which the species expanded in the Late Cenozoic period. Pronounced isolation of the populations in the Northern and the Central Tien Shan intramontane depressions appears as a factor from at least the Late Pliocene (E. stummeri) and the Middle Pleistocene (E. arguta) periods; and the association of the lizard habitats with loess deposits has given rise to the suggestion that there was an absence of serious change in their ranges during the Last Glacial Maximum (LGM). Low precipitation, a high annual temperature range and the high aridity of the climate in general beyond the ENM optimum of E. arguta all point to severe conditions for lizards surviving already in the eastern part of the Ily Basin and explain the limited species distribution in the highly arid deserts of Xinjiang. In terms of methodology, our data highlights the lack of a ‘generalized set’ of BIOCLIM parameters in the ecological niche modeling of the mountain species. In particular, moisture and solar radiation as well as the relief variables play an important role in the ecological health of the poikilothermic xerophilous species inhabiting mountain areas.

We have studied the terrestrial reptile fauna of the northwest Yazd province (Iran) and present here some of the characters that we examined for common species in the region. In total, 50 specimens from eight families (six lizard families and two snake families) were collected from the region. The collected lizards belonging to 13 species were Laudakia nupta, Phrynocephalus maculatus, Phrynocephalus scutellatus, and Trapelus agilis (Agamidae); Agamura persica and Bunopus crassicaudus (Gekkonidae), Teratoscincus bedriagai (Sphaerodactylidae); Eremias fasciata, Eremias persica, Mesalina watsonana, and Ophisops elegans (Lacertidae); Varanus griseus (Varanidae), and finally Uromastix asmussi belonging to the Uromastycidae. The two species of snakes were Spalerosophis diadema schiraziana (Colubridae) and Psammophis schokari (Lamprophiidae). Based on these results, Agamidae and Lacertidae are the families with highest number of genera and the genera Eremias and Phrynocephalus had the most species. Among the collected lizards, Trapelus agilis, Mesalina watsonana, and Bunopus crassicaudus were the most abundant species in the northwest Yazd province.

Although reptiles are the most diverse group of terrestrial vertebrates, crucial data on their extinction risks are lacking. The reptile species assessed by IUCN are only a fraction of those at risk of extinction. Thus, conservation planning and management decisions are hindered by the lack of ecological information on the species’ distribution patterns and their habitat requirements. Pleske’s racerunner (Eremias pleskei) is a rare and critically endangered species known to occur exclusively in the eastern Anatolian Montane Steppe ecoregion. In this study, we used ten species distribution model algo- rithms and 62 climate change scenarios (from 19 global climate models under four representative concentration pathways) to predict future habitat suitability for Pleske’s racerunner in the Anatolian Montane Steppe ecoregion. Our results indicate that this species may in future migrate from its current distribution range towards the central and western areas of the Anatolian Montane Steppe ecoregion. Our results also show that the variation in the temperature-related variables in suitable habitats will increase in future as compared with the current conditions. It seems that due to climate change, in future, deserts will be appropriate for this species. The same mechanisms, however, will make some of its current habitats unsuitable. Dealing with uncertainties in climate change and species distribution modeling is a major challenge when planning strategies for species’ conservation. We recommend conservation measures to be implemented to make sure that E. pleskei’s current habitats are suitable for it also in future.

A specially optimized restriction analysis of highly repetitive DNA elements, called DNA taxonprint, was applied for phylogenetic study of primates and lizards. It was shown that electrophoretic bands of DNA repeats revealed by the taxonprint technique have valuable properties for molecular systematics. Approximately half of taxonprint bands (TB) are invariable and do not disappear from the genomes during evolution or change spontaneously. Presumably these invariable bands are restriction fragments of dispersed DNA repeats. Another group represents variable taxonprint bands that differ even between closely related species. These variable bands are probably represented by tandem DNA repeats and could be used as species-specific markers. It was shown that taxonprint bands are independent characters since the appearance of a new taxonprint band does not change the previous band pattern. Phylogenetic reconstruction carried out on taxonprint data demonstrated that this approach could be of general utility for molecular systematics and species identification.

Unterscheidungsmerkmale für adulte Eremias strauchi und E. suphani sind das Vorhandensein einer doppelten oder einfachen, die Schuppen des dritten Submaxillariapaares trennenden Gulariareihe bei E. suphani (drittes Submaxillariapaares bei E. strauchi in Kontakt), das Vorhandensein von vergrößerten Gularia am dritten Submaxillariapaares bei E. strauchi (keine vergrößerten Gularia bei E. suphani), das Vorhandensein einer ventrolateralen Reihe scharf abgrenzender, großer, runder, weißer Flecken, die zu einem Band zusammenfließen können bei E. suphani (diffus angrenzende, kleine, längliche Flecken oder eine diffuse Längslinie bei E. strauchi) sowie verschiedene Dorsalzeichnungen. In der Türkei leben die Arten schwerpunktmäßig in zwei unterschiedlichen Steppenklimata, die durch jeweils vier humide, semihumide und aride Monate (E. strauchi) beziehungsweise acht humide und vier aride Monate (E. suphani) gekennzeichnet sind. E. strauchi und E. suphani treffen in der Senke von Doğubayazit aufeinander, wo sie parapatrisch leben. Die Habitate beider Arten sind ähnlich; es werden jeweils hat verbackene, lehmige Böden oder lockere, sandige Substrate mit einer spärlichen Vegetationsdecke besiedelt.

A phylogeny of the family Lacertidae was derived from mtDNA gene sequence data. Seventeen species, representing 16 currently recognized genera and subgenera, were included in the analysis. A total of 954 bp was obtained and aligned from 12S and 16S partial gene sequences. A preferred tree was selected based on weighted parsimony and functional ingroup and outgroup analyses. Decay analysis, bootstrapping, and permutation tail probability were used to evaluate support for the recovered nodes. The genus Gallotia was resolved as the basal taxon and the sister group of all remaining lacertids.Takydromus branched off next. All African lacertids grouped together and formed a monophyletic clade with the Eurasian genera Eremiasand Ophisops. The remaining Eurasian lacertids sequentially branched off near the base of the tree in a “comb-like” fashion. The basal position of Gallotia and the monophyly of African lacertids are consistent with previous hypotheses. The European-origin hypothesis of lacertids is favored, and the distribution of lacertids in Africa is likely a Miocene dispersal event. Most of the extant European lacertids probably arose after the Eocene. The classification of the family needs to be revised.

A phylogeny of the family Lacertidae was derived from DNA sequences of six mitochondrial genes. Only a few nodes were confidently resolved using maximum parsimony, although the data yielded a total of 1664 phylogenetically informative characters. The lacertids grouped into two subfamilies, the Gallotiinae which includes genera Gallotia and Psammodromus, and the Lacertinae which includes the remaining lacertids. The Lacertinae split into two additional groups. The African group included all African and Arabian lacertids and two Eurasian genera, Eremias and Ophisops; the remaining Eurasian lacertids were included in the Eurasian group. Most of the relationships within the African and Eurasian groups cannot be confidently resolved. A permutation tail probability test suggested that there is very little character covariance in the data to support these unresolved relationships. A recent explosive speciation hypothesis was invoked to explain the lack of structure of the data. The common ancestor of the Eurasian group, as well as the ancestor of the African group, experienced simultaneous, or almost simultaneous, multiple speciation events, which left none or very few characters fixed on the internodes. The phylogenetic reconstruction at the family level will be very difficult, if not impossible. Future phylogenetic research should focus on lower levels.

It is known that parasitic worms are an integral part of the natural ecosystem, performing a complex regulatory function. The aim of our study was to investigate the pathological changes that occur in the tissues of lizards exposed to parasites. In histological specimens of small intestine we observed cross sections of nematodes. The bodies of parasites with vaguely expressed organ structure and rounded formations of a small size, were surrounded by a wide strip of acellular eosinophilic mass; in the central parts there was a single rounded basophilic inclusion. On this basis we can assume that there is a formation of fibrosis, a protection against the parasite. Intestinal nematode parasitism in the studied lizards causes building of a xenoparasite barrier. The formation of the xenoparasite barrier is due to the adaptation of a parasitic agent and the host.

Squamata or scaled Reptiles are the largest order of new Reptiles including Lizards, Snakes and Amphisbaenia. They have formed 95 precent of new Reptiles. Our goal is Lizard Biodiversity of Torbat-e Heydaryeh in Razavi Khorasan Province. The study of Lizards Biodiversity of Torbat-e Heydaryeh in Razavi Khorasan Province was carried out in 2012 until 2013. In this research 132 specimens were collected and observed and identified on the basis of morphological, morphometric and meristic characters. The collected and observated Lizards belonging to 5 families: Agamidae, Lacertidae, Scincidae, Gekkonidae and Varanidae including 8 genera and 12 species. Results showed that Agamidae and Lacertidae families have the most frequency. The Agamidae family has the most genera and Lacertidae family has the most species. laudakia caucasia, laudakia microlepis, Trapelus sanguinolentus and Mesalina watsonana were the dominant species in this region and had a wider distribution rang in coparision with other species.

Karyological studies were conducted using bone marrow cell preparations from four species of Lacertidae and Scincidae from Iran: Eremias persica Blanford, Eremias kopetdaghica Szczerbak, Ophisops elegans Ménétries (Lacertidae), and Eumeces schneiderii princeps (Eichwald) (Scincidae). Eremias persica was diploid with 2n = 38 chromosomes. The karyotype consisted of eighteen pairs of acrocentric macrochromosomes and two microchromosomes. Eremias kopetdaghica was also diploid with 2n = 38 comprising one pair of metacentric macrochromosomes, seventeen pairs of acrocentric macrochromosomes, and one pair of microchromosomes. The chromosome count for these two species is reported for the first time herein. The chromosome count for Ophisops elegans (2n = 38) was in agreement with a previous report and was the first for the herpetofauna of Iran. Eumeces schneiderii princeps showed 32 macro- and microchromosomes, representing the first report for this subspecies.

The present paper proves that the endangered steppe runner (Eremias argutadeserti) still exists in the “Hanu Conachi River Sand Dunes” Nature Reserve. Prior to thisstudy it had not been recorded for almost 40 years and had been reported as extinct inthis region by the Romanian Red Data Book of Vertebrates. However, the majority of itsnatural habitat has been destroyed by the Robinia pseudoacacia plantations from thereserve. In order to ensure the survival of Eremias arguta deserti in the reserve, and inRomanian Moldavia, urgent measures have to be taken to reconstruct its natural habitatthrough the development of a management plan under the supervision and guidance ofexperts. At present, the steppe runner population from Hanu Conachi is extremelythreatened.

Iran contains 36 named endemic reptile species in 17 genera and seven families. The most endemic and speciose family is the Gekkonidae, followed by the Lacertidae. These two families collectively dominate with 22 species (or 60.1%) of the total endemic herpetofauna. Twenty one endemics are known only from a single location or restricted area within a single physiographic region. An analysis of endemicity is given in terms of systematics and distribution.

The genus Eremias, Fitzinger, 1834, with 35 species of mostly sand, steppe, and desert dweller lizards, is one of the most specious genera of the diverse family of Lacertidae. Here, we record E. fasciata from Hormozgan Province, a new location in southern Iran, and describe the specimens morphometrics. Previously published localities for E. fasciata in Iran lie between 450 and 1700 m elevation, while the elevation of this new locality is at about 15 m a.s.l.

Background.The Central Black-Earth region is an extensive territory with vari-ous physiographic conditions where the distribution and morphology of the steppe-runner are studied rather incompletely. And in particular, when carrying out this re-search our goal was to specify the habitat of the steppe-runner within the Central Black-Earth region and to study the features of external morphology of this species. Materials and methods. The research was conducted during field seasons of 2007–2017 in the territory of two regions of the Central Black-Earth region – Belgo-rod region and Voronezh region. For studying of external morphological features 28 individuals of the steppe-runner from two localities of Voronezh region were used. In the analysis of variability of proportions of a body and a pholidosis 17 signs were considered. The statistical analysis was carried out by means of the Statistica 10.0 program. Results and conclusions. As a result of the conducted research it has been estab-lished that the distribution of the steppe-runner within the Central Black-Earth re-gion coincides with sands of pine-forest terraces of the rivers. The northern border of the species’ habitat in the explored territory passes across Belgorod and Voronezh regions between 50 and 52° n.l. In the analysis of the quantitative and qualitative signs of the steppe-runner was found out that males authentically differ from fe-males in the tail length and the body-tail length ratio. When comparing with east and southern populations, the steppe-runners studied by us have rather smaller sizes of the tail and a smaller number of femoral pores.

The steppe racerunner (Eremias arguta) is one of the most widespread species of the Eurasian racerunners (genus Eremias), inhabiting steppes and semi-deserts of eastern Europe and central Asia from Romania to Mongolia and western China. Historically, 6 subspecies are recognized, and with 2 subspecies occurring in China; however, the taxonomical status of some subspecies is still controversial due in part to their high morphological variability. The present study deals with the intraspecies systematics of 28 samples representing 4 populations in Bole city and Ili River Valley, Xinjiang Uyghur Autonomous Region, China, through morphological comparison and phylogenetic analysis based on mitochondrial DNA cytochrome b (Cyt b) gene. Cyt b gene sequences of E. arguta available in the GenBank were compiled for comparison with the obtained haplotypes. Tree-based subspecies delimitation was achieved by using maximum parsimony, maximum likelihood and Bayesian phylogenetic analyses. Bayes factors (BF) were used to test the competing hypotheses for E. arguta by comparing the unconstrained Bayesian tree topology to Bayesian trees with `hard` constraints. The morphological features of steppe racerunner population in Bole city matched the description of those from the Ili River Valley, with specific dorsal pattern characterized by the presence of bright blue or green ocelli in breeding males. Phylogenetic trees congruently indicated that the haplotypes from Bole city belong to the Ili River Valley clade, which represents a separate lineage with undescribed subspecies (E. arguta ssp.). The 3 hypotheses that populations from the Ili River Valley belong to the subspecies E. a. arguta, or E. a. potanini, or E. a. uzbekistanica were rejected with very strong evidence (2lnBF>10), respectively. The Ili River Valley clade is most likely the sister taxon to E. a. uzbekistanica and E. a. darevskii; meanwhile, there is no reliable evidence to reject the alternative hypothesis that E. arguta ssp.is sister to the remaining lineages of E. a. arguta (2 < 2lnBF < 6). In addition, the reciprocal monophyly of E. a. potanini and E. a. arguta was recovered albeit with low bootstrap values and moderate Bayesian posterior probabilities. An alternative topology with samples of E. a. potanini nested within the E. a. arguta clade was not rejected with very strong evidence (6 < 2lnBF < 10). In conclusion, our results demonstrate that:(i) the steppe racerunner in Bole city is not E. a. potanini, but belongs to the Ili River Valley clade and thus represents a new record of E. arguta ssp. in Junggar Basin, Xinjiang, China; (ii) the populations from the Ili River Valley should not be classified as E. a. arguta or E. a. potanini or E. a. uzbekistanica, but belong to a cryptic clade (an undescribed subspecies); (iii) the phylogenetic placement of the novel clade (subspecies) is unclear and needing further clarification with integrative taxonomic approach. Finally, in combination with morphological variability, the validity of the E. a. potanini subspecies was discussed.

The tail regeneration frequency in 55 lizards from the Volgograd region was analyzed, among which were 12 steppe-runners (Eremias arguta (Pallas, 1773)) and 43 sand lizards (Lacerta agilis Linnaeus, 1758). The following cases of tail regenerates were observed: 0) a normal tail; 1) regeneration in the distal third; 2) a tail regenerated from the middle part; and 3) autotomy near the base (the proximal third). The majority of the lizards had normal tails (60.0% of E. arguta and 83.2/57.1% of L. agilis in females/males). Only 16.7% of the steppe-runners had regenerated tails in the distal part whereas 8.4% of females and 28.6% of males had autotomy with subsequent regeneration in the proximal third of the tail; 5.6% of females and 14.3% of males had regenerated autotomy in the distal part, and 2.8% of females had it in the middle part of the tail. Two lizards with bifurcated tails were found and described: a male of E. arguta and a female of L. agilis. A case of complicated abnormality of tail regeneration in a male of L. agilis is also described. An X-ray study has shown that caudal bifurcation may appear as a result of both the primary and secondary (in the cartilage tube) regeneration.

Multiple band patterns of DNA repeats in the 20–500-nucleotide range can be detected by digesting genomic DNA with short—cutting restriction endonucleases, followed by end labeling of the restriction fragments and fractionation in nondenaturing polyacrylamide gels. We call such band patterns obtained from genomic DNA ‘‘taxonprints’’ (Fedorov et al. 1992). Here we show that taxonprints for the taxonomic groups studied (mammals, reptiles, fish, insects—altogether more than 50 species) have the following properties: (1) All individuals from the same species have identical taxonprints. (2) Taxonprint bands can be subdivided into those specific for a single species and those specific for groups of closely related species, genera, and even families. (3) Each restriction endonuclease produces unique band patterns; thus, five to ten restriction enzymes (about 100 bands) may be sufficient for a statistical treatment of phylogenetic relationships based on polymorphisms of restriction endinuclease sites. We demonstrate that taxonprint analysis allows one to distinguish closely related species and to establish the degree of similarity among species and among genera. These characteristics make to use this phenomenon for phylogenetic aims (Cooke 1975; Christie and Skinner 1979; Brown and Dover 1979, 1980; Elizur et al. 1982; Hembelen et al. 1982; Buckland 1983; Dandieu et al. 1984; Lima de Faria et al. 1984; Shubina and Mednikov 1986; Turner et al. 1991), but this approach has not been extensively applied. In this paper we have reexamined the problem on the basis of our own preliminary results, partly published in Russian journals, confirming the ideas about possible correlations between evolution of DNA repeats and speciation (Fedorov et al. 1992; Grechko et al. 1993; Potapov and Ryskov 1993). We have demonstrated that the modified method designated ‘‘DNA taxonprint’’ (Fedorov et al. 1992) can be effectively used for revealing species—specific genomic markers in different taxonomic groups. These taxonprint markers are found to be helpful for evaluation of the degree of species similarity between species, genera, and families. More than 50 species from different taxa were studied.

Residual yolk is assumed to be an important source of energy and nutrients during early life in nonmammalian amniotes. Available data show that the mean size of residual yolk is far smaller in lizards than in turtles, snakes, crocodiles, and birds, raising a question of whether residual yolk is of functional significance in lizards. Here, we compared data from 26 lizard species with those from other nonmammalian amniotes to test the hypothesis that residual yolk is functionally less significant in species producing more fully developed offspring. In our sample, species mean offspring water contents ranged from 73% to 84% of body wet mass; species mean proportions of carcass dry mass, fat-body dry mass, and residual yolk dry mass to offspring dry mass ranged from 84% to 99%, 0% to 5.0%, and 0% to 14.4%, respectively. Lizards are, on average, more fully developed at hatching or birth than snakes, as revealed by the fact that the mean proportion of carcass dry mass to body dry mass and offspring water contents were both higher in lizards than in snakes. We conclude that the functional significance of residual yolk during early life is generally less evident in lizards. Even in the lizards where residual yolk is of potential functional significance, this portion of yolk contributes little, if any, to postembryonic growth. Future work could usefully collect data across a wider spectrum of reptile taxa to establish a precocial–altricial continuum and test the hypothesis that species with a smaller amount of residual yolk are closer to the precocial end of the continuum.

Eremias, or racerunners, is a widespread lacertid genus occurring in China, Mongolia, Korea, Central Asia, Southwest Asia and Southeast Europe. It has been through a series of taxonomic revisions, but the phylogenetic relationships among the species and subgenera remain unclear. In this study, a frequently studied region of the mitochondrial 16S rRNA was used to (i) reassess the phylogenetic relationships of some Eremias species, (ii) test if the viviparous species form a monophyletic group, and (iii) estimate divergence time among lineages using a Bayesian relaxed molecular-clock approach. The resulting phylogeny supports monophyly of Eremias sensu Szczerbak and a clade comprising Eremias, Acanthodactylus and Latastia. An earlier finding demonstrating monophyly of the subgenus Pareremias is corroborated, with Eremias argus being the sister taxon to Eremias brenchleyi. We present the first evidence that viviparous species form a monophyletic group. In addition, Eremias przewalskii is nested within Eremias multiocellata, suggesting that the latter is likely a paraphyletic species or a species complex. Eremias acutirostris and Eremias persica form a clade that is closely related to the subgenus Pareremias. However, the subgenera Aspidorhinus, Scapteira, and Rhabderemias seem not to be monophyletic, respectively. The Bayesian divergence-time estimation suggests that Eremias originated at about 9.9 million years ago (with the 95% confidence interval ranging from 7.6 to 12 Ma), and diversified from Late Miocene to Pleistocene. Specifically, the divergence time of the subgenus Pareremias was dated to about 6.3 million years ago (with the 95% confidence interval ranging from 5.3 to 8.5 Ma), which suggests that the diversification of this subgenus might be correlated with the evolution of an East Asian monsoon climate triggered by the rapid uplift of the Tibetan Plateau approximately 8 Ma.

The complete mitochondrial genome (mitogenome) of the Kyrghyz racerunner (Eremias nikoskii Bedriaga, 1905) from Kyrgyzstan was determined for the first time by next-generation sequencing. The mitogenome was 20,840 bp in length and comprised the standard set of 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, 22 transfer RNA genes, and a control region. The 13 concatenated PCGs were used to implement Bayesian phylogenetic analyses together with some congeners and three representative lacertids retrieved from GenBank. The monophyly of both Eremias and its viviparous group was recovered in the Bayesian phylogenetic tree, while the subgenus Pareremias was paraphyletic with respect to E. nikoskii. The mitogenome of E. nikoskii will faciliate the research on species delimitation, molecular evolution, and phylogenetic inference in the racerunner lizards.

Eremias argus often produces two clutches per breeding season in Chuzhou, Anhui Province, with females laying 2 to 5 eggs per clutch. Clutch size and clutch mass was positively correlated to female size (SVL); relative clutch mass was independent of female size; egg was independent of clutch size. There was no inter-clutch difference in clutch size, clutch mass and egg mass. Egg length was positively correlated to egg width. Egg length was negatively correlated to clutch size; and egg width was independent of clutch size. Females increased reproductive output mainly through increasing clutch size.

Reptiles are known hosts of a wide variety of parasites, including haemoparasites. Species of Lankestrella (Apicomplexa; Haemococcidia) have been described from the blood of lizards distributed in American and western European areas. In the present study, we characterized morphologically and molecularly the haemococcidian parasites (sporozoites) that infect the blood cells of Eremias persica and Ophisops elegans, two species of lacertid lizards from central Iran. By the microscopic examination of the smears, we identified parasites as the genus Lankestrella. In total, two positive samples of each species have investigated the basis of the partial 18S rRNA gene analyses. The result of similarity analysis with our sequences using the Basic Local Alignment Search Tool (BLAST) indicated a11 four parasites belonging to one haplotype of Lankestrella sp. The phylogenetic analysis revealed that the new Lankestrella sp is related to Lankestrella sp identified from two lizards belonging to Spain and Socotra Archipelago. This is the first report of Lankestrella parasites in the new lizard`s host. The present study provided additional information about the new host of Lankestrella species and added new knowledge to clarify the future phylogenetic relationship between these parasites. Our results emphasize the importance of screening haemococcidian parasites in Iran.

Reptiles are especially vulnerable to climate warming because their behavior, physiology, and life history are highly dependent on environmental temperature. In this study, we envisaged new probable mechanisms underlying the high vulnerability of lizards, wherein heat exposure induces oxidative stress and leads to immunosuppression. To test this hypothesis, we conducted a warming experiment on a lizard (Eremias multiocellata) from a desert steppe in Inner Mongolia from May to September using open-top chambers set up in their natural habitat and compared the components of oxidative stress (antioxidant ability [Superoxide dismutase (SOD) activity], extent of oxidative damage [malondialdehyde (MDA) content]), and immunocompetence (white blood cells [WBC] counts and immunoglobulin M [IgM] expression) between the warming and control groups. At the end of the experiment, the warming treatment did not affect the survival rate of the lizards. However, MDA content, but not SOD activity, was significantly higher in the warming group than in the control group. The WBC counts and IgM expression were significantly lower in the warming group than in the control group. Our results verified our hypothesis and provided novel cues and methods for the investigation of the mechanisms behind the high probability of extinction of other ectotherms under warming conditions.

We used the Mongolian racerunner Eremias argus as a model animal to evaluate the effects of constant versus fluctuating incubation temperatures on hatching success and hatchling phenotypes. Eggs were incubated under four constant [24, 27, 30 and 33 (±0.3) °C] and one fluctuating temperature regimes. Hatching success did not differ among treatments, and incubation temperature did not affect the sexual phenotype of hatchlings. Incubation length decreased exponentially as incubation temperature increased, and eggs incubated at fluctuating temperatures took a longer time to complete development than did those incubated at constant temperatures with the same mean. Of the hatchling phenotypes examined, body dry mass, carcass dry mass, residual yolk dry mass and locomotor performance of hatchlings were more likely to be affected by incubation temperature. Overall, locomotor performance was best in the low temperature treatments (24 °C and 27 °C) and worst in the high temperature treatment (33 °C), with the moderate temperature treatments (30 °C and fluctuating temperatures) in between. Our data show that: (1) daily exposure of eggs to extreme temperatures that are potentially lethal to embryos for brief periods does not have detectable adverse effects on hatching success and morphological phenotypes in E. argus; and (2) thermal fluctuations exert no positive effects on locomotor performance of hatchlings but influence incubation length differently than constant temperatures with the same mean.

Enantioselective toxicokinetics, accumulation, and toxicity of myclobutanil were investigated by oral exposure of myclobutanil enantiomers to lizards. After a single oral administration, the absorption half-lives () and elimination half-lives () were in the range of 0.133–14.828 and 3.641–17.682 h, respectively. The absorption and elimination half-lives of (+)-myclobutanil showed no significant differences from those of (-)-myclobutanil in lizard blood, whereas preferential enrichment of (-)-enantiomer was observed in the liver, fat, skin, intestine, lung and kidney. In the bioaccumulation experiments, the residue of (-)-myclobutanil was detected in most tissues at 7, 14, and 28 days, while (+)-myclobutanil was found only in lizard skin, at a concentration lower than that of (-)-myclobutanil. Thus, (-)-myclobutanil was preferentially accumulated in lizards. The transcriptional responses of metabolic enzyme genes indicated that cytochrome P450 1a1 (cyp1a1), cyp2d3, cyp2d6, cyp3a4 and cyp3a7 played a crucial role in the metabolism of (+)-myclobutanil, whereas cyp1a1, cyp2d3, cyp2d6, cyp2c8, and cyp3a4 contributed to the metabolism of (-)-myclobutanil. The difference in metabolism pathways may be a reason for the enantioselectivity of myclobutanil in lizard. Myclobutanil also affected the expression of antioxidant enzyme genes, and the (+)-myclobutanil treatment might produce higher oxidative stress in lizard liver when compared with its antipode. Hepatic histopathological changes such as hepatocellular hypertrophy, nuclear pyknosis, vacuolation, and non-zonal macrovesicular lipid accumulation were observed in the liver of lizards for both (+)-myclobutanil and (-)-myclobutanil treatments. Thus, myclobutanil could affect lizard liver upon multiple exposure. The findings of this study provide specific insights into the enantioselective metabolism and toxicity of chiral triazole fungicides in lizards.

The enantioselective accumulation, elimination and metabolism of fenbuconazole in lizards were determined following a single-dose (25 mg/kgbw) exposure to racemic or enantiomeric fenbuconazole. Accumulation of fenbuconazole was found in lizard fat with rac-form > enantiopure enantiomers. The enantiomer fractions (EFs) were higher than 0.5 in the blood, while EFs were less than 0.5 in the liver, brain, skin and stomach. There was conversion from (+)-fenbuconazole to (−)-fenbuconazole in lizard liver and conversion from (−)-fenbuconazole to (+)-fenbuconazole in lizard liver and blood. The results showed that enantioselective accumulation appeared in lizards, but the direction varied among blood and different tissues. The elimination half-lives (t1/2) of (+)-fenbuconazole were higher than those of (−)-fenbuconazole in the blood and liver, suggesting that (−)-fenbuconazole eliminated faster than (+)-fenbuconazole in these tissues. In addition, both (+)-fenbuconazole and (−)-fenbuconazole eliminated faster in the liver and stomach exposed to racemate than those exposed to enantiopure enantiomers. On the contrary, the form of racemate decreased the elimination rate of fenbuconazole in lizard fat. Synergistic elimination may occur when two enantiomers coexisted in lizard liver and stomach, while the racemate produced antagonistic elimination in lizard fat. Simultaneously, three metabolites, RH-6467, RH-9029&RH-9030 and keto-mchlorophenol, were discovered in lizard liver. Only two metabolites, RH-6467 and RH-9029&RH-9030, were found in lizard blood. RH-9029&RH-9030 were the major metabolites. The discovered enantiomers of (+)-fenbuconazole metabolites were different from those of (−)-fenbuconazole. The findings of this study may provide a better understanding of the enantioselective behaviors of chiral triazole fungicides in reptiles.

1.As postulated by life‐history theory, not all life‐history traits can be maximized simultaneously. In ectothermic animals, climate warming is predicted to increase growth rates, but at a cost to overall life span. Maternal effects are expected to mediate this life‐history trade‐off, but such effects have not yet been explicitly elucidated. 2. To understand maternal effects on the life‐history responses to climate warming in lizard offspring, we conducted a manipulative field experiment on a desert‐dwelling viviparous lacertid lizard Eremias multiocellata, using open‐top chambers in a factorial design (maternal warm climate and maternal present climate treatments × offspring warm climate and offspring present climate treatments). 3. We found that the maternal warm climate treatment had little impact on the physiological and life‐history traits of adult females (i.e. metabolic rate, reproductive output, growth and survival). However, the offspring warm climate treatment significantly affected offspring growth, and both maternal and offspring warm climate treatments interacted to affect offspring survival. 4. Offspring from the warm climate treatment grew faster than those from the present climate treatment. However, the offspring warm climate treatment significantly decreased the survival rate of offspring from maternal present climate treatment, but not for those from the maternal warm climate treatment. 5. Our study demonstrates that maternal effects mediate the trade‐off between growth and survival of offspring lizards, allowing them to grow fast without a concurrent cost of low survival rate (short life span). These findings stress the importance of adaptive maternal effects in buffering the impact of climate warming on organisms, which may help us to accurately predict the vulnerability of populations and species to future warming climates.

DNA sequences from parts of the 12S, 16S and cytochrome b mitochondrial genes, which totalled 1049 aligned base pairs, were used to estimate the relationships of 49 species of Lacertidae, including representatives of 19 out of the 23 recognized genera and 23 species of the paraphyletic genus Lacerta. These data were used, together with morphological information, to estimate the relationships within the family. Molecular evidence corroborates the monophyletic status of many genera and species groups originally based on morphology. It indicates that Psammodromus forms a clade with Gallotia, which is the sister taxon of all other lacertids. These comprise three units: the primarily Afrotropical armatured group; the largely Oriental Takydromus; and the west Palaearctic Lacerta and its derivatives, Podarcis and Algyroides. Morphology also supports the first three assemblages, but suggests that they are derived from a paraphyletic Lacerta. Within Lacerta and its allies, DNA sequence analysis corroborates the affinity of some members of each of the subgenera Lacerta s. str. and Timon, and of the L. saxicola group. It also supports the relationship of L. monticola, L. bonnali and L. horvathi, and suggests that the L. parva–L. fraasi clade and L. brandti are not related to Psammodromus–Gallotia, as morphology indicates, but instead are associated respectively with the L. danfordi and L. saxicola groups. DNA sequence data provide additional evidence that the eastern Arabian `Lacerta` jayakari and `L.` cyanura are members of the armatured clade and also sister species. Our analysis supports an origin for present lacertids in west Eurasia. The armatured clade invaded Africa, probably in the mid-Miocene, spreading widely and evolving increasingly xeric-adapted forms, one lineage of which later moved back into the Palaearctic. `Lacerta` jayakari and `L.` cyanura are assigned to Omanosaura, Lutz and Mayer 1986. The name Gallotiinae Cano, Baez, Lopez-Jurado and Ortega, 1984 is available for the Gallotia–Psammodromus clade, Eremiainae Shcherbak 1975 for the armatured clade and Lacertinae for Lacerta, Podarcis and Algyroides. Two new subgenera of Lacerta are proposed here: Caucasilacerta for L. saxicola and its allies, and Parvilacerta for L. parva and L. fraasi.

Den Iran als Urlaubsziel zu wählen, dies dürfte wohl den wenigsten Deutschen einfallen. Dabei verfügt dieses riesige Land über eine reichhaltige Kultur und ist auch unter herpetologischen Gesichtspunkten sehr interessant. Andererseits bietet der Iran fast keine touristische Infrastruktur und ist dem Tourismus auch nicht wirklich aufgeschlossen - angefangen dabei, dass Kreditkarten nicht akzeptiert werden, bis hin zur Kopftuchpflicht für alle Frauen, egal welcher Nationalität oder Glaubensrichtung sie angehören. Dies alles schreckte uns jedoch nicht davon ab, per Fahrrad ca. 3600 Kilometer von Istanbul bis nach Tehran zu fahren, weitestgehend entlang der alten Seidenstrasse.

The evolutionary diversification of many terrestrial vertebrate groups is strongly linked to climatic events in the Cenozoic, the period from 65 Million years ago to today when modern animals first appeared. I investigated the effects of Cenozoic climate change on the taxonomic and morphological diversification of the Old World lizard family Lacertidae, with particular emphasis on the African radiation. African lacertids exhibit an unusual pattern of diversification, in which their highest species richness occurs in deserts north and south of the equator, despite being spread throughout the continent. This disparity is particularly surprising given that desert lacertids are thought to be evolutionarily younger than their mesic-dwelling relatives, suggesting increased diversification rates in arid habitats. To identify the evolutionary factors underlying this pattern, I use a combination of phylogenetic, morphological and ecological techniques. In Chapter 1, I apply Bayesian methods and fossil-based calibrations to molecular sequence data to construct a time-calibrated phylogeny for Lacertidae. I estimate that the family arose in the early Cenozoic, with the majority of their African radiation occurring in the Eocene and Oligocene. In Chapter 2, I describe changes in lacertid body shape across biomes and substrates, and find widespread morphological convergence in similar habitat types. I suggest that in addition to foraging demands, fluctuating and extreme climatic conditions, largely driven by precipitation and temperature, contribute to morphological convergence across independent arid-dwelling clades. Finally, I test if ancestral transitions in ecology, morphology, and rates of diversification temporally coincide with paleoclimatic events in the Cenozoic. I use High Resolution X-ray Computed Tomography to characterize changes in the skull related to life in arid habitats, and apply maximum likelihood methods to test if the origins of those traits temporally coincide with significant shifts in habitat, diversification rates and climatic changes. My results show that African lacertids experienced three major peaks in diversification, accompanied by the evolution of suites of arid-adapted morphological traits. These changes coincide with climatic shifts in Africa, including the transition from closed forests to open grasslands and savanna in the late Oligocene, prior to the peak temperatures of the mid-Miocene Climatic Optimum, and following the formation of the Benguela current leading to hyper-aridity in southern Africa. I conclude that deserts are important centers for reptile evolution, but that expected changes in climate due to global warming may outpace the ability of arid-dwelling species to adapt and persist in the future.

Background: Although current molecular clock methods offer greater flexibility in modelling evolutionary events, calibration of the clock with dates from the fossil record is still problematic for many groups. Here we implement several new approaches in molecular dating to estimate the evolutionary ages of Lacertidae, an Old World family of lizards with a poor fossil record and uncertain phylogeny. Four different models of rate variation are tested in a new program for Bayesian phylogenetic analysis called TreeTime, based on a combination of mitochondrial and nuclear gene sequences. We incorporate paleontological uncertainty into divergence estimates by expressing multiple calibration dates as a range of probabilistic distributions. We also test the reliability of our proposed calibrations by exploring effects of individual priors on posterior estimates. Results: According to the most reliable model, as indicated by Bayes factor comparison, modern lacertids arose shortly after the K/T transition and entered Africa about 45 million years ago, with the majority of their African radiation occurring in the Eocene and Oligocene. Our findings indicate much earlier origins for these clades than previously reported, and we discuss our results in light of paleogeographic trends during the Cenozoic. Conclusion: This study represents the first attempt to estimate evolutionary ages of a specific group of reptiles exhibiting uncertain phylogenetic relationships, molecular rate variation and a poor fossil record. Our results emphasize the sensitivity of molecular divergence dates to fossil calibrations, and support the use of combined molecular data sets and multiple, well-spaced dates from the fossil record as minimum node constraints. The bioinformatics program used here, TreeTime, is publicly available, and we recommend its use for molecular dating of taxa faced with similar challenges.

While global variation in taxonomic diversity is strongly linked to latitude, the extent to which morphological disparity follows geographical gradients is less well known. We estimated patterns of lineage diversification, morphological disparity and rates of phenotypic evolution in the Old World lizard family Lacertidae, which displays a nearly inverse latitudinal diversity gradient with decreasing species richness towards the tropics. We found that lacertids exhibit relatively constant rates of lineage accumulation over time, although the majority of morphological variation appears to have originated during recent divergence events, resulting in increased partitioning of disparity within subclades. Among subclades, tropical arboreal taxa exhibited the fastest rates of shape change while temperate European taxa were the slowest, resulting in an inverse relationship between latitudinal diversity and rates of phenotypic evolution. This pattern demonstrates a compelling counterexample to the ecological opportunity theory of diversification, suggesting an uncoupling of the processes generating species diversity and morphological differentiation across spatial scales.

The aim of this study is to detect areas of endemism in lizards in Iran. This is the first study of its kind focusing on this subject. Areas of endemism for two families of lizards (Lacertidae and Gekkonidae) that have the highest number of endemic species than other lizard families in Iran were identified by Parsimony Analysis of Endemicity (PAE). Distribution data were collected from previous studies on the Iranian lizards and also from the recent literature on the descriptions of new endemic species. A total of 81 species of lizards were available for analysis. The study area was divided into a 2° × 2° grid of 63 Operational Geographic Units (OGUs). PAE was applied to the data matrix to detect areas of endemism and detected eight areas of endemism in southwestern Iran and near the Persian Gulf. Southern Iran is the main region where most species from Arabia came into Iran and were stopped in their dispersal. Two grids in southern and northeastern Iran were recognized as the areas with the highest density of species in the studied families. Lacertidae and Gekkonidae did not have a shared endemic species in the region (cells 59 and 60) but the area of endemism identified by PAE in the Persian Gulf region suggests that exchange between Iranian and Arabian herpetofauna was very high during interglacial periods. The distribution pattern of the endemic species of these families is concentrated in the region of the Alborz and the Zagros Mountains, but the single area of endemism in southern Iran has an important role in the historical biogeography of the Iranian herpetofauna. During interglacial periods, the Persian Gulf acted as a corridor between the herpetofauna of the two sides and this suggests the importance of this area of endemism for the Gekkonidae family. Also, the OGUs with the highest density of species are located around the country and, the lowest density is in the Central Plateau. PAE detected eight areas of endemism in southwestern Iran, but according to the number of species per units, two OGUs can be identified as high density in northeastern and southern Iran.

During a field survey in the Sistan region of Iran in October 2011, habitat of Eremias acutirostris was surveyed and four specimens of the species were collected. We report a locality situated along the road from Zabol to Doost Mohammad, near the town of Bonjar. The fragile habitat, consist of immobile sand dunes, is situated in proximity to an industrial zone, placing this remnant population under threat of pollution and other anthropogenic edge effects. We call the Zabol Environmental Protection Agency to act and insure the species’ future in Iran.

Eremias lalezharica MORAVEC, 1994 was until recently known only from its terra typica near Lalehzar village in the Lalehzar Mountains, in the center of Kerman province, Iran. During a recent survey, a new locality was found for Eremias lalezharica on the road from Jiroft to Darb-e Behesht, in the Babgorgi region, 100 km to the south-east of the terra typica along the Lalehzar Mountains, with coordinates 29º 05’ N and 57º 32’ E, and an elevation of 2890 m (8670 ft). This new locality is also mountainous with relatively rich vegetation.

In Iran Eremias grammica is a critically endangered lacertid lizard only known from a single population in the east of Khorasan Razavi province. During a new survey of this area (September 2011) it has become clear that this population of Eremias grammica no longer exists, due to habitat destruction. However, a new population of Eremias grammica was found in similar sand dunes around Jangal city, and habitat protection is suggested.

Eremias intermedia and Eremias lineolata are two species from the genus Eremias that are found in the Sarakhs region (at the border of Iran and Turkmenistan) (N: 36º 19’ 32.4” ; E: 61º 08’ 35.4”; altitude: 330 m). That particular region has very unfavorable conditions for lizards. Aridity and Human activity (agriculture) affected on their habitat. A water channel was being constructed to carry water to the city and for this reason, machines were employed which destroyed the sand dunes.

Eremias strauchi strauchi and Eremias strauchi kopetdaghica are genetically and morphologically distinct and are distributed allopatrically in northeastern and northwestern Iran. E. s. strauchi is distinguishable by having green spots on lateral parts of the body, while E. s. kopetdaghica is characterized by white spots and irregular black dots on lateral parts of the body. Recent molecular studies have suggested that these are two distinct species, but other types of analyses leave their classification unclear. In this study, we evaluated their taxonomic status using additional data (including ecological niches) to confirm the hypothesis that they are two species. All known records of their occurrence were employed to predict and evaluate the suitable areas where they may be expected to be found in Iran. We then performed niche similarity tests (niche identity and background tests) and point-based analyses to compare their ecological niches and explain ecological differentiation. Niche models of E. s. strauchi and E. s. kopetdaghica had good results and powerful performance based on high area under the curve (AUC) values [E. s. strauchi = 0.992, standard deviation (SD) = ± 0.008; E. s. kopetdaghica = 0.978, SD = ± 0.032]. Ecological differentiation has been found across the entire range, indicating that ecological differentiation had an important role in species differentiation. Environmental conditions for the species diverged along environmental variables, as precipitation of coldest quarter for the “Strauch” subspecies and precipitation of warmest quarter for the “Kopet dagh” subspecies were most important in determining habitat suitability, respectively. These two factors are important in niche differentiation between the two species and influenced their genetic divergence. Finally, our results confirmed the niche differentiation between E. s. strauchi and E. s. kopetdaghica and added new insights into the taxonomic distinction between E. s. strauchi and E. s. kopetdaghica.

In north Khorasan province, Iran, we compared the effectiveness of two types of traps for collecting reptiles: funnel traps and pitfall traps. Three stations were monitored over three 10-day periods and in total 544 individuals (including 200 re-captures) belonging to 5 species and 4 families of lizards (Lacertidae) were collected. Funnel traps with 280 captures were more efficient than pitfall traps with 264 captures, but the differences between the two traps are not significant. Three species were captured most often in the three different stations respectively: station 1, Bunopus crassicauda (22% relative frequency); station 2, Eremias fasciata (29% relative frequency); and station 3, Trapelus agilis (32% relative frequency). Shannon species richness indices were higher for pitfall than funnel traps (i.e., 1.45 vs. 1.40), but the difference was not significant. Pitfall traps were better for capturing species that search widely for food, while the funnel traps preferentially captured species that climb plants, such as Trapelus agilis. We recommend using both types of trap to capture the various types of species in any one region.

Outbreaks of grasshoppers (Orthoptera: Acrididae) often cause serious ecological damage. Recently, there has been interest in using natural enemies of grasshopper for their biological control. This study examined the biology and predation on grasshoppers by Eremias argus, a common lizard in Inner Mongolia. Its developmental duration and life history are consistent with adaptation to grasshopper phenology. The diet structure of E. argus included grasshoppers, beetles, ants, leafhoppers, moths, bees and spiders. A positive correlation between E. argus population numbers and grasshopper population numbers was highly significant. We built models describing the functional response and intraspecific competition for E. argus adults. The functional feeding response of E. argus on grasshopper was classed as Holling type III. The maximum number of grasshoppers consumed by female and male adults were 11.2 and 7.0 individuals per day, respectively. Predatory ability was strongest in female adults, with the second and third instars of Oedaleusasiaticus preferred. The predation ratios(E) of E. argus on grasshoppers declined with increasing lizard density, especially for female adult E. argus. E. argus could play an important role in grasshopper control and maintaining a population of E. argus in the grassland ecosystem could effectively control low-density grasshopper populations on grassland. Suggestions on how E. argus could fit into an IPM programme for biological control of grasshopper are discussed.

In this study, we aimed to determine the amphibian and reptile species distributed in Agri province (Turkey), as well the major factors threatening the species. For this purpose, we conducted 4 field excursions (20 days totally) at 223 different point, covering all the squares of 1:25.000 layout map. As a result of the literature and field survey, we recorded 4 anuran (Pseudepidalea variabilis, Pelophylax ridibundus, Rana camerani, R. macrocnemis), 2 chelonian (Mauremys caspica, Testudo graeca), 16 lizard (Paralaudakia caucasia, Phrynocephalus horvathi, Ablepharus bivittatus, Trachylepis aurata, Darevskia bendimahiensis, D. raddei, D. valentini, D. sapphirina, D. unisexualis, D. uzzelli, Eremias suphani, E. strauchi, E. pleskei, Lacerta media, Ophisops elegans, Parvilacerta parvd) and 14 snake (Typhlops vermicularis, Dolichophis jugularis, D. schmidti, Eirenis eiselti, E. modestus, E. collaris, Coronella austriaca, Hemorrhois ravergieri, Natrix natrix, N. tessellata, Platyceps najadum, Eryx jaculus, Montivipera wagneri, M raddei) species in Agri province, which is totally 4 amphibians and 32 reptiles. Three Anatolian endemic species (Darevskia sapphirina, Eirenis eiselti, Montivipera wagneri) and 7 species more was recorded in Agri as s first time in the literture. Taking into account the very limited herpetofaunal information available in the literature for Agri province, a significant contribution was made with this work. This study was conducted as a part of `The Ministry of Forestry and Water Affairs, General Directorate of Nature Conservation and National Parks National Biodiversity Inventory and Monitoring Project`.

The life and work of the Alsatian Louis Amédée Lantz (1886-1953), a pioneer of European herpetology. A trained and professional research-chemist, the Alsatian Louis Amédée Lantz was an active and particularly dynamic herpetologist. His residence of nearly twelve years in Russia enabled him to make several field trips to regions such as the Caucasus and Iran. He always carried with him a home made telescopic net that he used to catch lizards. That net became symbolic of Lantz for most people around him. He realized significant herpetological collections mainly deposited in the Museum of the Zoology Institute of the Russian Academy of Sciences in St. Petersburg. Soon after the Russian Revolution in 1917, he had to leave the country and stayed for a few years in France before joining England. During this period, Lantz visited the French Pyrenees and the Mediterranean border (Hyeres Islands, Bandol), enabling him to discover for the first time oviparous populations of common lizard and also to describe a new species of lizard from the French Pyrenees. Lantz is also at the origin of the discovery of unisexual reproduction by parthenogenesis in reptiles. His collaboration with the Swedish amateur herpetologist Otto Cyrén, whom he met through the German herpetologist Willy Wolterstorff, was particularly successful throughout his career. Lantz died at the age of 66 years, in Switzerland, as he was about to join the team of herpetologists at the Natural History Museum in Paris.

Several recent papers have reviewed the life and work of French herpetologist Louis Amédée Lantz. They have detailed the composition of his collections deposited in several museums. However, since then, several other im- portant specimens from his collections have come to light. We here identify the syntypes of Eremias zarudnyi Lantz, 1928, which were located in Russia. We provide data on the type series, an English translation of the French description of E. zarudnyi and designate and describe a lectotype for the species.

Several recent papers have reviewed the life and work of French herpetologist Louis Amédée Lantz. They have detailed the composition of his collections deposited in several museums. However, since then, several other important specimens from his collections deposited at the Natural History Museum (NHM, UK) have come to light and we here present all of them in detail. We discovered paralectotypes of Lacerta saxicola obscura Lantz & Cyrén (BMNH 1918.11.21.5–7), syntypes of Lacerta boemica Sukhov (BMNH 1960.1.4.26–30, BMNH 1965.337–342) and Lacerta viridis media Lantz & Cyrén (BMNH 1960.1.4.25, 1966.512). We also identified numerous specimens from the French Mediterranean islands in Lantz’s collection deposited at the NHM, some of which represent the first reported specimens of their species from certain islands. We here provide data on all these specimens. We also place the Mediterranean island specimens from the Lantz collection in their historical context and emphasize the historical and taxonomic value of these collections.

Takhar Province of Afghanistan was previously known to harbour only two species of amphibians and eight species of reptiles with no record of snake species. From 2020 to 2021, we collected herpetological data from the Province and identified 14 species and specimens representing species complexes (Bufotes viridis complex and Trapelus agilis complex), with first records of Testudo hors fieldii (Testudinidae), Paralaudakia badakhshana (Agamidae), Pseudopus apodus (Anguidae), Tenuidactylus caspius (Gekkonidae), Eumeces schneideri (Scincidae) and Varanus griseus (Varanidae). In addition, we report the first province records of snakes, includ ing Eryx tataricus (Erycidae), Hemorrhois ravergieri (Colubridae), Natrix tessellata (Natricidae) and the venomous species Naja oxiana (Elapidae). These records connect and supplement previously obtained data of these species from surrounding provinces and neighbouring countries. Our data reveal that Takhar Province is home to at least 20 species of amphibians and reptiles with a strong affiliation to the Turanian chorotype. All these data are a significant source of information for the diversity of herpetofauna in Afghanistan and subsequent biodiversity research in the Central Asiatic region.

This study provides observation on 21 species of amphibians and reptiles obtained during various field trips in Afghanistan from 2007 to 2018. The core of this study is distributional data collected mostly by the second author of this paper that were systematically evaluated. Our records show a notable expansion of the current distribution range for several species and highlight the need for more extensive further sampling within the entire country. The first record of Cyrtopodion agamuroides (Nikolsky, 1900) complex for Afghanistan is presented here, increasing the number of herpetofauna in the country to 117 species.

In order to analyze food item of Eremias argus collected in Taeanhaean national park, we analyzed six specimens, 4 females and 2 males, and these specimens maesured the morphological characteristics such as Snout-vent length (SVL), Head width (HW) to 0.01 mm using digital caliper. Additionally we analyzed statistical analysis by SPSS 11.0 program. As a results, Food item of E. argus appeared 8 orders, 13 families in stomach content, then food item composed Lepidoptera (30.6%), Araneae (20.4%), Dermaptera (18.4%), Amphipoda (10.2%), Coleoptera (8.2%), Homoptera (6.1%), Orthoptera (4.1%) and Neuroptera (2.0%).

Eremias argus, which specifically inhabits riverside or coastal sand dune, is an endangered species designated by the Ministry of Environment of Korea because it has been drastically decreasing due to the destruction of habitat and the human activities. Therefore, it is required to prepare a countermeasure for the strategic and systematic solutions for the conservation of the E. argus. This study analyzed mtDNA cytochrome oxidase subunit I (COI) gene of E. argus inhabiting Yoobu-do island and Sohwang sand dune. This study aims to provide fundamental genetic information through phylogeographical analysis between two regions. Of 11 individuals of E. argus used in the analysis, the total 652~656 bp of mtDNA COI genes for 3 individuals of Takydromus wolteri as `out group` were analyzed. Intraspecific genetic distance for E. argus was shown to be the same result of 0.000. As for T. wolteri, it was 0.005, showing very similar result. T. wolteri inhabiting Gapcheon stream in Daejeon metropolitan city was found to be the highest intraspecific genetic distance (0.008). The NJ tree of E. argus and T. wolteri indicated there was almost no genetic difference between habitat for E. argus. For T. wolteri, however, there was slight difference between the individuals inhabiting Yoobu-do island and those inhabiting Gapcheon stream in Daejeon metropolitan city. Therefore, it is necessary to prepare conservation strategies to increase genetic diversity of E. argus in Yoobudo island in the future because it is highly presumed that the population of E. argus in Yoobu-do island have been flown from nearby coastal sand dune.

Little is known about altitudinal distribution of lizards in Iran. In the present study we studied distribution pattern of members of family Lacertidae along the eleveatinal gradient in Iran. To determine environmental drivers of distribution pattern of 48 lizard species, all known valid members of family Lacertidae, along elevational gradient in Iran. Firstly, we classified Iran digital elevation model (DEM) based on 100m intervals, that resulted in 56 altitudinal bands and number of species in each band was recorded. Secondly, we extracted mean value of following variables; altitude, slop, area, solar radiation index (SRI), normalized differences vegetation index (NDVI), annual precipitation, precipitation of wettest month, precipitation of driest month precipitation, precipitation of wettest quarter, precipitation of driest quarter, and precipitation of warmest quarter, and using VIF measure correlated variables were removed. Finally, we performed a multiple regression and found that area and precipitation of warmest quarter are the most important drivers of distribution pattern of family Lacertidae along elevational gradient in Iran. General distribution pattern of family Lacertidae was unimodal and maximum number of species living from 1475 m to 1675 m.

Spatial gradients of species richness can be shaped by the interplay between historical and ecological factors. They might interact in particularly complex ways in heterogeneous mountainous landscapes with strong climatic and geological contrasts. We mapped the distribution of 171 lizard species to investigate species richness patterns for all species (171), diurnal species (101), and nocturnal species (70) separately. We related species richness with the historical (past climate change, mountain uplifting) and ecological variables (climate, topography and vegetation). We found that assemblages in the Western Zagros Mountains, north eastern and north western parts of Central Iranian Plateau have the highest number of lizard species. Among the investigated variables, annual mean temperature explained the largest variance for all species (10%) and nocturnal species (31%). For diurnal species, temperature change velocity shows strongest explained variance in observed richness pattern (26%). Together, our results reveal that areas with annual temperature of 15–20 °C, which receive 400–600 mm precipitation and experienced moderate level of climate change since the Last Glacial Maximum (LGM) have highest number of species. Documented patterns of our study provide a baseline for understanding the potential efect of ongoing climate change on lizard diversity in Iran.

the Lacertidae is one of the most diverse and widespread lizard families throughout Eurasia and Africa. Several studies so far have attempted to unravel the phylogeny of Lacertidae using morphological and mole- cular data. However, the intra-family relationships remain unclear. in an effort to explore the phylogenetic relationships within the family Lacertidae, a concatenated dataset of 5727 bp from six genes (two nuclear and four mitochondrial) and 40 genera was assembled based on GenBank database. Phylogenetic inference analy- ses were conducted using Maximum Parsimony (MP), Bayesian inference (Bi) and Maximum Likelihood (ML), revealing that even a combined dataset of both mitochondrial and nuclear genes is not able to resolve the phylogenetic relationships of the Lacertidae family under the tribe level.

This work presents data on reproductive features of Ukrainian fauna Lacertidae lizards in laboratory conditions and comparative data on lizards clutches in wild nature. Terms of egg incubation of these lizards in the laboratory in a stable, relatively low temperatures can significantly exceed those in nature, which allows to obtain embryonic material with a smooth, long process of development. The most prolific representatives of different major types - green lizard (Lacerta viridis) and nimble (Lacerta agilis). Females sand lizard can be aggressive towards other females clutches, which is manifested in the destruction of nests.

Aims The Zagros Mountains are a part of the 20th global hotspot, the Irano-Anatolian biodiversity hotspot. In this study, we aim to develop a comprehensive checklist of endemic herpetofauna species in the Zagros Mountains as one of the biodiversity hotspot regions, to provide more information about this important area and the necessity of conservation programs to protect it. Materials & Methods The Zagros Mountains, with an area of about 533,543km2, ranges from Turkey and Iraq to western and southwestern Iran along the eastern edge of the Persian Gulf. A list of endemic species has been collected from the literature review. Findings This region contains 3 species and 7 subspecies of endemic amphibians belonging to three genera and two families, the Salamandridae (8) and the Bufonidae (2). Neurergus and Calliopersa are endemic to this hotspot. There are 40 species and 6 subspecies of endemic reptiles belonging to 24 genera and 10 families. The families with the greatest number of endemic species are the Gekkonidae, Phyllodactylidae, and Colubridae. Three genera, Asaccus, Mediodactylus, and Eirenis, dominate the region, with 32 endemic taxa. There are also two endemic genera, Parsigecko and Lakigecko. Conclusion Many amphibians in the Zagros Mountains, especially all the species of the genus Neurergus, are categorized in IUCN (the International Union for Conservation of Nature) Red List and CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora). The habitats of the Zagros Mountains herpetofauna, especially those of endangered and endemic species, should be protected and managed to maintain or restore populations of the declining species.

Eremias Fitzinger, 1834 is a speciose Eurasian genus of true lizards with approximately 40 species. Eremias species occurring in Pakistan have never been examined before using molecular genetics. In the present study, six out of seven morphologically defined taxa distributed in Pakistan (E. acutirostris, E. aporosceles, E. cholistanica, E. kakari, E. persica, and E. scripta) were studied using mitochondrial (16S rRNA, cytochrome c oxidase subunit I, cytochrome b) and nuclear (Rag1) genes. Data of 29 individuals were included in phylogenies using ENA/GenBank sequences. With a maximum of 20 species per analyzed data set, this study represents the most complete phylogeny of the genus to date. Maximum Likelihood and Bayesian analyses were run for concatenated (3,528 bp) and single-locus data sets and supported by uncorrected p distance calculations to evaluate the phylogenetic placement and divergence of Pakistani taxa. Among the Pakistani taxa, we detected six mostly well-supported and deeply divergent clades (A-F) differing by uncorrected p distances of up to 23.8% for mtDNA (cytb) and 3.3% for the nuclear Rag1 locus. Despite morphological differences between E. aporosceles and E. acutirostris (both clade A), no unambiguous genetic support was found for these two taxa. Therefore, we regard E. aporosceles as a synonym of E. acutirostris. On the other hand, E. persica was found to represent a species complex with deeply diverged clades (E and F) in Pakistan. Eremias cholistanica (clade D) and E. kakari (clade B), two morphologically defined endemic taxa of Pakistan, were revealed as phylogenetically clearly distinct. Eremias scripta (clade C) from Pakistan was found to be genetically deeply divergent compared to sequences of this taxon from Afghanistan and Uzbekistan. Our study provides evidence that the current taxonomy of Eremias does neither reflect the genetic diversity nor the evolutionary history of the genus, necessitating a comprehensive integrative taxonomic revision of the whole genus.

Materials and methods. Observations of Amphibians and Reptiles were carried out during two tourist trips in March 2016 and in May 2018 in the Iranian provinces of Gilan and Ardebil.
Results. New data on the distribution of 6 species of Amphibians (Bufo eichwaldi, Bufotes variabilis, Hyla orientalis, H. savignyi, Pelophylax ridibundus, Rana pseudodalmatina) and 21 species of Reptiles (Emys orbicularis, Paralaudakia caucasia, Trapelus ruderatus, Darevskia chlorogaster, D. defilippii, D. raddei, Eremias strauchi, Iranolacerta brandtii, Lacerta strigata, Ophisops elegans, Ablepharus bivittatus, Heremites auratus, Pseudopus apodus, Eryx jaculus, Eirenis punctatolineatus, Hemorrhois ravergieri, Platyceps najadum, Telescopus fallax, Xerotyphlops vermicularis, Natrix natrix, N. tessellata) in the study area were obtained. The author compares the obtained data with the results of other Herpetological researches in the region.
Conclusions. In general, the herpetofauna of the Caspian slopes of the Talysh Range in Iran is an inseparable part of mesophilic herpetocomplexes with the prevalence of gyrcan elements common from the north-western foothills of Talysh in Azerbaijan to the Western Kopetdag in Turkmenistan.

Information about the mating behaviors of an endangered species is critical for the understanding of the natural history of the species as well as in situ and ex situ breeding programs designed to rehabilitate field populations. We describe the mating behaviors of the Mongolian racerunner (Eremias argus), an endangered species in South Korea. The mating of this species consists of precopulatory, copulatory, and postcopulatory stages and is composed of 12 different mating behaviors. During the postcopulatory stage, other males or females not involved in mating show more interference behaviors than during the precopulatory and copulatory stages. The male E. argus has an extraordinarily long postcopulatory bite, which may function as a type of mate-guarding behavior. This study is the first report on the mating behavior of a South Korean reptile.

To understand oviposition and egg hatching of the Mongolian racerunner (Eremias argus) in the laboratory and field, we allowed 21 female lizards to lay their eggs, collected eggs, measured mass, length, and width of the eggs, incubated the eggs, and measured mass and snout-vent length (SVL) of hatchlings. Females laid about 3 eggs per clutch over two clutches in a breeding season between late May and early July, 2010, and buried the eggs in the sand at approximately 15 – 20 cm depth. Mass, length and width of the eggs from the first and second clutches in the laboratory were not different. The relative clutch mass (total egg mass/gravid female mass) of the first clutch in the laboratory was smaller as 0.26 than 0.39 of the second clutch in the field. The incubation period of eggs in a common used incubator was shorter as 38 days than 50 days of a hand-made incubator although the former showed about 5% hatching failure. Mass and SVL of hatchlings were not different depending on the incubator types, common used and hand-made incubators, and on the first and second clutches in the laboratory.

Information on habitat use is critical in sizing protected areas for endangered reptile species.To investigate habitat use,home range,and hibernaculum of the endangered Mongolian Racerunner (Eremias argus),we radio-tracked 40 specimens in a coastal sand dune in South Korea.Of the 163 locations recorded during the breeding season,150 (92.0％) were in grass sand dunes,and the rest (8.0％),all associated with the same lizard,were in shrub sand dunes.All of the 123 locations recorded during the non-breeding season were in grass sand dunes.No lizards were found in the grasslands abutting the dunes.The four lizards with identifiable hibernation sites were found under an average of 17.8 cm of sand and were all located in grass sand dunes.The lizards moved approximately 5 m daily and used 162 m2 of home range (computed by minimum convex polygon,MCP) during the breeding season,and they moved approximately 2 m and used 68 m2 of home range during the non-breeding season.However,the mean daily moved distances and MCP home ranges were not statistically significantly different between the seasons or between males and females.Our results suggest that in coastal sand dunes,E.argus uses grass sand dunes as its main habitat throughout the year.This finding could be used to determine the appropriate habitat size and to designate for the conservation of this endangered species.

In this study, we have evaluated the physical characteristics of neonate, female, and male Mongolian racerunners (Eremias argus) and determined the age structure of a population of the species in a field located in Taean-gun, Chungnam, South Korea. The physical parameters of females and males, including snout-vent length (SVL), head length, head width, and body mass were found to be significantly interrelated. Male Mongolian racerunners exhibited significantly longer heads than the females, but other physical parameters, such as SVL, head width, and body mass did not differ between the female and male specimens. In the study population, the females ranged in age from two to eleven years old and the males ranged between two to eight years of age. The number of females and males, when separated into different age classes, did not differ within each age class. Male Mongolian racerunners evidenced greater SVL growth coefficients than the females, but asymptotic SVL did not differ between the females and males.
