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.

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.

The final part of a series of papers on the lizards of the Caucasus, that have been published in previous years. The paper reports on the life habits, capture and keeping in terraria of several lizards of Soviet Transcaucasia. In these respects the agamid Phrynocephalus helioscopus persi- cus and three species of the lacertid genus Eremias occuring in that area (i. e. strauchi, velox, pleskei) are discussed. Finally a !ist of all lizard species and subspecies actually known to occur in this region is given.

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.

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.

In this investigation, a total of 44 racerunner lizard samples (Eremias pleskei, Eremias strauchi, and Eremias suphani) collected from eastern part of Turkey were examined for the first time for helminths. Eremias pleskei was harboured 1 species of acanthocepalan (in cystacanth stage), E. strauchi was harboured 2 species of nematodes, and E. suphani was harboured 3 species of nematodes and 1 species of cestode. E. strauchi represents a new host record for Spauligodon eremiasi, and Spauligodon saxicolae E. suphani represents a new host record for Spauligodon eremiasi, S. saxicolae, Physaloptera sp., and Oochoristica tuberculata, and also, E. pleskei represents a new host record for unidentified acanthocepalan (in cystacanth stage). Also, Turkey is a new locality record for Spauligodon eremiasi.

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.

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.

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.

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.

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.

Turkey is biogeographically diverse and consequently has a rich herpetofauna. As a result of active herpetological research, the number of species has steadily increased in recent years. I present here a new checklist of amphibian and reptile species distributed in Turkey, revising the nomenclature to reflect the latest taxonomic knowledge. In addition, information about the systematics of many species is also given. In total 35 (19.4%) amphibian and 145 (80.6%) reptile species comprise the Turkish herpetofauna. Among amphibians, 16 (45.7%) anurans and 19 urodelans (54.3%) are present. Among reptiles, 11 (7.6%) testudines, 71 (49%) saurians, 3 (2.1%) amphisbaenians and 60 (41.3%) ophidians are considered part of the herpetofauna. The endemism rate in Turkey is considered relatively high with a total of 34 species (12 amphibian species – 34.3% and 22 reptile species – 15.2%) endemic to Turkey, yielding a total herpetofaunal endemism of 18.9%. While 38 species have not been threat-assessed by the IUCN, 92 of the 180 Turkish herpetofaunal species are of Least Concern (LC), 13 are Near Threatened (NT), 10 are Vulnerable (VU), 14 are Endangered (EN), and 7 are Critically Endangered (CR). In addition, 6 species are in the DD (Data Deficient) category.

The albumins from 41 species of the family Lacertidae representing a substantial part of genera as well as infrageneric groups of the collective genus Lacerta s.l. were investigated by means of the MCF technique. The data allow a chronological estimation of the most important radiation events and their correlation with paleogeographical facts. Our results are in remarkable contradiction to the phylogeny presented by ARNOLD (1989a) based mainly on morphological characters. The most important phylogenetic relationships are: 1. The genera Gallona and Psammodromus are already isolated from the other taxa since the Oligocene. We assess these main branches as subfamilies Gallotiinae and Lacertinae. 2. Lacerta s.str. and Lacerta subgenus Zootoca form the sister group of the remaining Lacertinae. 3. A colonization of Africa in the Lower Miocene has led to a separation in two lines, with mainly Eurasian and African members respectively. 4. ARNOLD`S (I.e.) `Ethiopian and advanced Saharo-Eurasian clade` proved to be a paraphyletic unit, one group of genera being more closely related to European taxa. All techniques applied to the systematics of Lacertidae hitherto are critically discussed. An area-time- hypothesis concerning the phylogeny of Lacertidae is presented. Key words: Lacertidae, phylogeny of; Gallotiinae subfam. nov.; Lacertinae subfam. nov.; micro complement fixation; albumin evolution.

The family Lacertidae encompasses more than 250 species distributed in the Palearctis, Ethiopis and Orientalis. Lacertids have been subjected in the past to several morphological and molecular studies to establish their phylogeny. However, the problems of convergent adaptation in morphology and of excessively variable molecular markers have hampered the establishment of well supported deeper phylogenetic relationships. Particularly the adaptations to xeric environments have often been used to establish a scenario for the origin and radiation of major lineages within lacertids. Here we present a molecular phylogenetic study based on two nuclear marker genes and representatives of 37 lacertid genera and distinct species groups (as in the case of the collective genus Lacerta). Roughly 1600 bp of the nuclear rag1 and c-mos genes were sequenced and analyzed. While the results provide good support to the hitherto suggested main subfamilies of Gallotiinae (Gallotia and Psammodromus), Eremiainae and Lacertinae [Harris, D.J., Arnold, E.N., Thomas, R.H., 1998. Relationships of lacertid lizards (Reptilia: Lacertidae) estimated from mitochondrial DNA sequences and morphology. Proc. R. Soc. Lond. B 265, 1939–1948], they also suggest unexpected relationships. In particular, the oriental genus Takydromus, previously considered the sister-group to the three subfamilies, is nested within Lacertinae. Moreover, the genera within the Eremiainae are further divided into two groups, roughly corresponding to their respective geographical distributions in the Ethiopian and the Saharo-Eurasian ranges. The results support an independent origin of adaptations to xeric conditions in different subfamilies. The relationships within the subfamily Lacertinae could not be resolved with the markers used. The species groups of the collective genus Lacerta show a bush-like topology in the inferred Bayesian tree, suggesting rapid radiation. The composition of the subfamilies Eremiainae and Lacertinae as well as their phylogeography are discussed.

Aim Body size is instrumental in influencing animal physiology, morphology, ecology and evolution, as well as extinction risk. I examine several hypotheses regarding the influence of body size on lizard evolution and extinction risk, assessing whether body size influences, or is influenced by, species richness, herbivory, island dwelling and extinction risk. Location World-wide. Methods I used literature data and measurements of museum and live specimens to estimate lizard body size distributions. Results I obtained body size data for 99% of the world`s lizard species. The body size–frequency distribution is highly modal and right skewed and similar distributions characterize most lizard families and lizard assemblages across biogeographical realms. There is a strong negative correlation between mean body size within families and species richness. Herbivorous lizards are larger than omnivorous and carnivorous ones, and aquatic lizards are larger than non-aquatic species. Diurnal activity is associated with small body size. Insular lizards tend towards both extremes of the size spectrum. Extinction risk increases with body size of species for which risk has been assessed. Main conclusions Small size seems to promote fast diversification of disparate body plans. The absence of mammalian predators allows insular lizards to attain larger body sizes by means of release from predation and allows them to evolve into the top predator niche. Island living also promotes a high frequency of herbivory, which is also associated with large size. Aquatic and nocturnal lizards probably evolve large size because of thermal constraints. The association between large size and high extinction risk, however, probably reflects a bias in the species in which risk has been studied.

Aim Temperature influences most components of animal ecology and life history – but what kind of temperature? Physiologists usually examine the influence of body temperatures, while biogeographers and macroecologists tend to focus on environmental temperatures. We aim to examine the relationship between these two measures, to determine the factors that affect lizard body temperatures and to test the effect of both temperature measures on lizard life history. Location World-wide. Methods We used a large (861 species) global dataset of lizard body temperatures, and the mean annual temperatures across their geographic ranges to examine the relationships between body and mean annual temperatures.We then examined factors influencing body temperatures, and tested for the influence of both on ecological and life-history traits while accounting for the influence of shared ancestry. Results Body temperatures and mean annual temperatures are uncorrelated. However, accounting for activity time (nocturnal species have low body temperatures), use of space (fossorial and semi-aquatic species are ‘colder’), insularity (mainland species are ‘hotter’) and phylogeny, the two temperatures are positively correlated. High body temperatures are only associated with larger hatchlings and increased rates of biomass production. Annual temperatures are positively correlated with clutch frequency and annual longevity, and negatively correlated with clutch size, age at first reproduction and longevity. Main conclusions Lizards with low body temperatures do not seem to have ‘slower’ life-history attributes than species with high body temperatures. The longer seasons prevalent in warm regions, and physiological processes that operate while lizards are inactive (but warm enough), make environmental temperatures better predictors of lizard life-history variation than body temperatures. This surprisingly greater effect of environmental temperatures on lizard life histories hints that global warming may have a profound influence on lizard ecology and evolution.

The etymology of the reptiles, especially the lizards of Iran has not been completely presented in other published works. Iran is a very active geographic area for any animals, and more especially for lizards, due to its wide range deserts and ecology. We have attempted to ascertain, as much as possible, the construction of the Latin binomials of all Iranian lizard species. We believe that a review of these names is instructive, not only in codifying many aspects of the biology of the lizards, but in presenting a historical overview of collectors and taxonomic work in Iran and Middle East region. We have listed all recorded lizards of Iran according to the order of the scientific names in the book of Anderson, The Lizards of Iran. All lizard species and types have been grouped under their proper Families, and then they have been alphabetically ordered based on their scientific binominal nomenclature. We also examined numerous published works in addition to those included in the original papers presenting each binomial.

The global struggle to conserve as many species as possible with limited resources requires an improvement of our knowledge on the distribution of biodiversity. In Iran, the state of knowledge is poor for most groups of organisms, except few vertebrate groups and vascular plants. Reptiles are one of the best known, most diverse vertebrate groups in Iran, with a high rate of endemism (ca. 29%), but distribution patterns and related environmental drivers remain poorly understood. In the present study, based on a large publicly available dataset, we use general additive modelling (GAM) to identify explanatory variables for species richness of reptiles in Iran. Results indicate heterogeneity parameters (range +entropy) as the variables with the highest explanatory values. Based on the grid cells of the predicted environmental richness, using hotspot analysis, we suggest seven hotspots of reptile diversity (HRDs) across the country. Our results corroborate the previously recognized HRDs and detect three additional ones, located alongside the major mountain ranges around the central deserts plateau, particularly in the Zagros Mountains. Four of the largest HRDs (ca. 90%) situate within the Irano-Anatolian and Caucasus global biodiversity hotspot. In addition, our results reveal a large gap between identified HRDs and the current network of protected areas (PAs) in the country. While three of the detected HRDs in this study are partially touched (ca. 18%) by the PA network, overall, these areas are only covered by less than 10%. Therefore, the effectiveness of the current PAs for the protection of the reptile diversity of Iran is questionable.

Many animals display complex colour patterns that comprise several adjacent, often contrasting colour patches. Combining patches of complementary colours increases the overall conspicuousness of the complex pattern, enhancing signal detection. Therefore, selection for conspicuousness may act not only on the design of single colour patches, but also on their combination. Contrasting long- and short-wavelength colour patches are located on the ventral and lateral surfaces of many lacertid lizards. As the combination of long- and short-wavelength-based colours generates local chromatic contrast, we hypothesized that selection may favour the co-occurrence of lateral and ventral contrasting patches, resulting in complex colour patterns that maximize the overall conspicuousness of the signal. To test this hypothesis we performed a comparative phylogenetic study using a categorical colour classification based on spectral data and descriptive information on lacertid coloration collected from the literature. Our results demonstrate that conspicuous ventral (long wavelength-based) and lateral (short wavelength-based) colour patches co-occur throughout the lacertid phylogeny more often than expected by chance, especially in the subfamily Lacertini. These results suggest that selection promotes the evolution of the complex pattern rather than the acquisition of a single conspicuous colour patch, possibly due to the increased conspicuousness caused by the combination of colours with contrasting spectral properties.

We present an annotated checklist for a total 241 reptiles and 22 amphibians including 5 frogs, 9 toads, 7 newts and salamanders, 1 crocodile, 1 worm lizard, 148 lizards, 79 snakes and 12 turtles and tortoises, includes the most scientific literature up to August 2014 and also based on several field surveys conducted in different Provinces of Iran from 2009 to 2014. We present an up-to-dated checklist of reptiles and amphibians in Iran. We provide a comprehensive listing of taxonomy, names, distribution and conservation status of all amphibians and reptiles of Iran. This checklist includes all recognized named taxa, English names for classes, orders, families, species, subspecies along with Persian names for species, including indication of native and introduced species. For the first time we report two non-native introduced reptiles from natural habitats of Iran. Of the total 22 species of amphibians in Iran, 6 (27.2%) are endemic and of the total 241 species of reptiles, 55 (22.8%) are endemic. Of the 22 amphibians species in Iran, 3 (13%) are Critically Endangered, 2 (9%) are Vulnerable and of the 241 reptile species 3 (1.2%) are Critically Endangered, 4 (1.6%) are Endangered and 10 (4.1%) are Vulnerable. Accordingly, this paper combines significant aspects of taxonomy, common names, conservation status and distribution of the Iranian herpetofauna.

This book shows a comprehensive picture of the reptiles, excluding snakes, living in Europe, North Africa, Middle and Near East and Central Asia. The bulk of the book is an annotated checklist and a distributional atlas of approx 500 species of lizards, crocodiles, turtles and terrapins, and amphisbaenians, living in the Western Palearctic. Information on distribution, subspecies, chorotype and main references are provided for each species, as well as 226 colour maps showing the global distribution of the species on a grid of one degree. For each species map the bibliographic and original sources (more than 850 sources are listed) are indicated. A further 83 maps show the distribution of all genera and main species groups of Palearctic reptiles. Beside the checklist and the atlas, in some additional chapters the following arguments are treated: Materials and methods; status of knowledge on the Palearctic fauna; composition of the Western Palearctic reptile fauna (including a statement on biodiversity and species richness); descriptive biogeography (including a discussion on the Palearctic region boundaries based on reptile distribution and the herpeto-geographic sectors of the Western Palearctic); conservation status. A list of more than 730 references quoted in the text and high quality colour plates including photos of the most of the supraspecific taxa living in the study area completes the book.

We present a comprehensive summary of the distribution of the lizards of Iran accompanied by an annotated checklist. The updated maps of distribution of all 146 species of 41 genera of 11 families are based on all available bibliographic records, catalogues of museum collections and our own field observations. The final dataset used for the distribution maps contains 8525 georeferenced records and cover 41% of the country when plotted on a grid of 0.25° × 0.25° resolution. The dataset is publicly accessible through GBIF portal (http://www.gbif.org/dataset/7db4f705-61ae-4c6e-9de2-06674e7d46b2). Following the latest biogeographic division of the country, ~53% of the species (76 species) inhabit the Iranian Province, ~41% (60 species) the Western Asian mountain transition zone, ~9% (13 species) the Turanian Province, and ~18% (27 species) the Arabian Province. In addition, ~2% (3 species) reach Iran from the Indo-Malay biogeographic region and ~2% (3 species) are believed to have been introduced to Iran by humans. Endemic species (46) represent ~32% of the known species diversity. The most species-rich family of lizards in Iran is Lacertidae with 47 species, followed by Gekkonidae (41), Agamidae (18), Scincidae (15), Phyllodactylidae (10), Sphaerodactylidae (4), Eublepharidae and Uromastycidae (3), Anguidae and Varanidae (2), and Trogonophidae with one representative.

Elements of the herpetofauna are in the author`s opinion of great importance for the zoogeographical division of the Palaearctic region. It is suggested that this region be divided into the following four subregions: 1/ arctic, 2/ boreal Euro-Siberian, 3/ bo- real Himalayan-Manchurian and 4/ Mediterranean-Central-Asiatic.

Composition and density of vegetation are important habitat quality indicators for reptiles. The goal of this note was to determine dominant plant species, optimal size and density in habitats of syntopic lizards in the Goravan Sands Sanctuary. The role of vegetation variables was considered in relation to differences in thermoregulation of syntopic Phrynocephalus persicus, Eremias pleskei, and Eremias strauchi.Microhabitats of P. persicus differed from that of E. pleskei and of E. strauchi by a relatively frequent encounter of the plant Achillea tenuifolia, which is considered as potential habitat quality indicator. Phrynocephalus persicus generally used microhabitats with sparser vegetation. It is supposed that the excessive growth of shading vegetation can have a more negative impact on P. persicus than on E. pleskei.

The results of five expeditions (1995, 1996, 2007, 2011, and 2012) to the north-eastern and eastern Turkey are presented. These data were collected from the Pontic (Lazistan) Ridge, Choroch River basin, and the upper flow basins of the Aras River, Kura River, Euphrates River, Tiger River, Dogankent (Kharshit) River, and the Van Lake basin. In total, 2 Caudata, 6 Anura, 2 Testudines (3 subspecies), 25 Sauria (30 subspecies) and 21 Serpentes species were found.

Knowledge on the spatial distribution of taxa is crucial for the decision-making processes in conservation and management of biodiversity that rely on precise distribution data. We present an annotated list for a total of 37 amphibian (20 caudatans and 17 anurans) and 141 reptile species (11 chelonians, 70 lizards, 3 amphisbaenians and 57 snakes) in Turkey, using both available scientific literature up to December 2020 and our own fieldwork data from 1987 to 2020. We provide a comprehensive listing of taxonomy, names, distribution and conservation status of Turkish amphibians and reptiles. The herpetofauna list will be particularly useful for establishing national conservation priorities as well as for placing Turkish fauna into phylogenetic and biogeographic contexts. We compiled information published in books, journals and various web sources and added our personal data. We projected the data in the WGS84 coordinate system and created an overlay grid with cells of 50x50 km2. The database comprises more than 500 grid cells and 11,913 records. As a result, the distribution of Turkish amphibians and reptiles has been extensively mapped with geographical information systems and a database has been created. The obtained data will be useful in planning future studies on taxonomy, ecology and conservation of Turkish amphibians and reptiles.

In this study, it is aimed to determine Amphibian and Reptilian species of Ararat Mountain and near Environment, threats to species and precautions to be taken against these factors. For these purposes, total of 18 days herpetological trips carried out in Ararat Mountain between 2011-2017. As a result of the trips and literature searches, 4 Anuran (Bufotes variabilis, Pelophylax ridibundus, Hyla savignyi, Pelobates syriacus), 2 Chelonian species (Mauremys caspica, Testudo graeca) 10 lizard species (Paralaudakia caucasia, Phrynocephalus horvathi, Heremites auratus, Eumeces schneiderii, Eremias strauchi, Eremias pleskei, Darevskia valentini, Lacerta strigata, Ophisops elegans, Pseudopus apodus) and 13 snake species (Xertoyphlops vermicularis, Dolichophis schmidti, Eirenis collaris, Hemorrhois ravergieri, Natrix natrix, N. tessellata, Platyceps najadum, Zamenis hohenackeri, Z. longissimus, Eryx jaculus, Malpolon insignitus, Macrovipera lebetina, Montivipera raddei) a total of 4 amphibians and 25 reptilian species belonging to 14 families were determined in Ararat Mountain.
