The new subspecies differs from the other M. xanthina populations by pholidosis; higher number of intercanthals and lower number of subcaudalia. Also, the whiteness between windings or spots on dorsum pattern were observed in new subspecies, similar to the southern populations. Furthermore, the spots on the ventrals became denser in the mid-body and forms darker colorization at the end of body of the males and the tail tips are yellowish-orange or light orange on both sexes. © 2020, Institute for Biodiversity and Ecology.Öğe A new subspecies, Lyciasalamandra atifi oezi n. ssp. (Urodela: Salamandridae) from Gazipasa (Antalya, Turkey)(Centre for Biodiversity of Montenegro, 2016) Tok, Cemal Varol; Afsar, Murat; Yakin, Batuhan YamanIn this study, a new subspecies of the Lycian salamander, Lyciasalamandra atifi oezi n. ssp., was described from Gazipasa (Antalya, Turkey). The Lyciasalamandra specimens collected in Doganca (Gazipasa, Antalya) are clearly distinguished from the known subspecies of L. atifi by the very small and few white flecks on the dorsal ground pattern or by the absence of the flecks in some specimens. The light coloration, which can be distinctly observed in front of, behind, and under the eye of L. atifi, is indistinct in the new subspecies, unlike the other subspecies. The body length was observed to be shorter than that of the nominate subspecies but close to that of L. a. bayrami. In juveniles, scattered black flecks are striking on the posterior parts of their parotoids and, unlike adults, denser small and white flecks are striking on top of the head as well as on the dorsum, the tail, and the extremities. In addition, scattered yellow flecks in different sizes and shapes are present on the dorsal tail.Öğe A new subspecies, Ophisops elegans budakibarani n. Subsp. (Sauria: Lacertidae) from Mut (Mersin/Turkey)(Universitatea din Oradea, 2017) Tok, Cemal Varol; Afsar, Murat; Yakin, Batuhan Yaman; Ayaz, Dinçer; Çiçek, KerimThis study describes a new subspecies of Ophisops elegans from vicinity of Mut, Mersin, Turkey and named Ophisops elegans budakibarani n. subsp. The new subspecies is distinguished from geographically the closest subspecies O. elegans basoglui, found in the south of its distribution, by having higher number of the longitudinal row of scales+plates at mid-trunk (SPM) and a characteristic venter coloration (whitish coloration instead of lemon yellow color in venter of both sexes during the breeding season) and from O. elegans centralanatoliae, found in the north of its distribution, by having lower number of SPM and a characteristic dorsum color-pattern (less distinct tile reddish-brown coloration in the temporal band, missing large blackish spots in the vertebral and paravertebral area). © 2017 Biharean Biologist, Oradea, Romania.Öğe ADDITIONAL MORPHOLOGICAL DATA ON Vipera (Pelias) cf. darevskii FROM THE VICINITY OF ZEKERIYAKOY (NORTHEASTERN ANATOLIA)(Folium Publ Co, 2018) Tok, Cemal Varol; Afsar, Murat; Cicek, KerimTwo new Viper specimens obtained from Zekeriyakoy (Ardanuc, Artvin) in Northeastern Anatolia were investigated. When obtained data were compared with the related literature, it was observed that pholidosis characteristics and body measurements of the retrieved specimens were similar to both Vipera (Pelias) olguni and Vipera (Pelias) darevskii. The specimens were considered to be V. cf. darevskii since their defining characteristics were more similar to V. darevskii than V. olguni.Öğe Age, Growth and Longevity of Kotschy's Gecko, Mediodactylus kotschyi (Steindachner, 1870) (Reptilia, Gekkonidae) from Central Anatolia, Turkey(Inst Zoology, Bas, 2015) Cicek, Kerim; Afsar, Murat; Kumas, Meltem; Ayaz, Dincer; Tok, Cemal VarolWe studied the age structure of Kotschy's gecko, Mediodactylus kotschyi, from the Sultan Mountains (Central Anatolia, Turkey) using the skeletochronological method. We examined the humeral diaphyseal cross sections of a total of 19 (six males and 13 females) museum specimens. Our results showed that the age structure ranged from three to seven years (mean = 4.2 years, SD = 1.47) in males and from two to eight years (mean = 4.5 years, SD = 1.81) in females. Both sexes reached sexual maturity after their second hibernation, and no statistically significant difference in age composition was observed between the sexes. There was a strong positive correlation between SVL and age (Spearman's correlation coefficient, r = 0.93) and Von Bertalanffy growth curves fitted to the relationships between age (k = 0.80) and SVL (SVLmax = 42.4). In conclusion, M. kotschyi is a short-lived species with a high growth rate.Öğe Amphibians of the Borçka-Karagöl Nature Park (Artvin / Turkey) and Vicinity(2018) Afsar, Murat; Afsar, Birgül; Ayaz, Dinçer; Çiçek, Kerim; Tok, Cemal VarolAmphibian species and their distribution of the Borçka-Karagöl natural park and its environs wasdetermined between 2003-2006 and 2015-2017 by field studies. A total of seven amphibian species were foundin the Karagöl Nature Park and its vicinity, including five species of anurans [Rana macrocnemis, Pelophylaxridibundus, Hyla orientalis, Pelodytes caucasicus and Bufo verrucosissimus] and two newts [Mertensiellacaucasica and Ommatotriton ophryticus]. It has been determined that species of Rana macrocnemis, Pelophylaxridibundus, Hyla orientalis, Pelodytes caucasicus, Bufo verrucosissimus, Mertensiella caucasica and Ommatotritonophryticus inhabits at 1465 meters altitude in Karögöl as syntopically. Between 1465-1750 m, Rana macrocnemis,Pelophylax ridibundus, Hyla orientalis, Pelodytes caucasicus, Bufo verrucosissimus and Ommatotriton ophryticussyntopically inhabits and between 1750 and 2200 m, Rana macrocnemis and Mertensiella caucasica species livetogether. At Karagöl, Pelophylax ridibundus is dominate species while Rana macrocnemis is dominate species inthe forest and subalpine region.Öğe Conservation activities for Mountain viper, Montivipera albizona (Nilson, Andrén and Flärdh, 1990) in Anatolia, Turkey(Union of Scientists in Bulgaria - Plovdiv, 2018) Çiçek, Kerim; Afsar, Murat; Bağda, Efkan; Tok, Cemal VarolThe Mountain viper, Montivipera albizona, is an endemic to Anatolia and distributes in Anatolian Diagonal, Anti-Taurus Mountains and Amanos Mountains. Unfortunately, the species faced serious threats within narrow distribution range. Here, we evaluated the present status and main threats of the Mountain viper by 60-days intensive fieldwork and interviews with locals. According to our data, the Mountain viper prefers the rocky and those mountainous and rugged areas covered with less vegetation and they are active from the beginning of April to end of November. In spring, it is possible to observe 1 to 5 individuals in the suitable habitats depending on its density. We prepared 5-year Action Plan for Turkish General Directorate of Nature Conservation and National Parks and planned the roadmap for sustainability of the species with participation of regional administration, NGOs, and locals. We found that agricultural activities, overgrazing, road constructions, quarries, pet trade, sportive hunting, deliberate or accidental killing, and climatic change are the main threats on the Mountain viper in Anatolia. The main conservation measures include: creating some protected habitats in the high viper density regions, long-term monitoring survey to obtain data on its ecology and population trends, education and awareness raising activities among locals to prevent illegal collection/killing of the vipers. © Ecologia Balkanica.Öğe Conservation strategies for the Caucasus Viper, Vipera kaznakovi Nikolsky 1909, in the East Black Sea Region, Turkey(Aves, 2020) Tok, Cemal Varol; Afsar, Murat; Cicek, KerimWe evaluated the current status and main threats to the Caucasus viper (Vipera kaznakovi Nikolsky 1909), from the East Black Sea Region, Turkey, via 21 days of intensive fieldwork and interviews with locals. We found that habitat loss and destruction, illegal collection, and intentional or accidental killings are the main threats to V. kaznakovi in the region. We prepared a 5-year Action Plan for the Turkish General Directorate of Nature Conservation and National Parks and outline a strategy for promoting the sustainability of the species with participation of regional administrations, non-governmental organizations (NGOs), and locals. The major conservation measures include: (1) creating protected areas in regions with high viper densities (2) preventing and controlling illegal collection, (3) raising awareness among locals to reduce the intentional and accidental killing of vipers.Öğe Cyrtopodion (Mediodactylus) kotschyi (STEINDACHNER, 1870) from Civril, Denizli (western Turkey)(Pensoft Publishers, 2011) Afsar, Murat; Ayaz, Dincer; Afsar, Birgul; Cicek, Kerim; Tok, Cemal Varol[Anstract Not Available]Öğe Data on nocturnal activity of Darevskia rudis (Bedriaga, 1886) (Sauria: Lacertidae) in Central Black Sea Region, Turkey(Institute for Biodiversity and Ecology, 2018) Afsar, Murat; Sahin, Mehmet Kursat; Afsar, Birgül; çiçek, Kerim; Tok, Cemal VarolInteractions between the environment and internal regulation drive the biophysiological dynamics of lizards. Although diurnal lizards are usually heliothermic, they can sometimes be active in the absence of sunlight. Here, we report, for the first time, a case of nocturnal behavior (aided by the artificial light) in the spiny-tailed lizard - Darevskia rudis (Bedriaga, 1886) - a species that normally exhibits diurnal activity. © 2018 Centre for Biodiversity of Montenegro.Öğe More data on the distribution and morphology of Mediodactylus kotschyi bolkarensis (ROsLER, 1994), from Central Anatolia, Turkey(Pensoft Publishers, 2017) Afsar, Murat; Cicek, Kerim; Tok, Cemal VarolFour specimens of the gecko, Mediodactylus kotschyi bolkarensis (ROsLER, 1994), were found in Karapmar (Province of Konya, Turkey), about 50 km north west of the known range. Two male and two female adult specimens collected from this new locality were examined in detail for their pholidosis and color pattern features, and compared with 26 adult (11 male, 15 female) specimens recently collected from Eregli (Province of Konya, TR), the type locality of the subspecies bolkarensis. The comprehensive new materials of M. k. bolkarensis are characterized with regard to metric, meristic and color-pattern traits which are presented in comparison to published data of six neighboring subspecies of M kotschyi.Öğe New record localities of five snake Species in Turkey(Osterreichische Gesellschaft Herpetologie E V, 2013) Afsar, Murat; Cicek, Kerim; Dincaslan, Yumus Emre; Ayaz, Dincer; Tok, Cemal Varol[Anstract Not Available]Öğe New records of Eurasian Blind Snake, Xerotyphlops vermicularis (Merrem, 1820) from the Black Sea region of Turkey and its updated distribution(Universitatea din Oradea, 2016) Afsar, Murat; Çiçek, Kerim; Tayhan, Yahya; Tok, Cemal VarolIn this study, we report two new localities of Xerotyphlops vermicularis from western and central Black Sea Region. With these records, the distribution of the species is extended about 90km to the north. The specimens were examined morphologically and compared with the relevant literature. In addition, on the basis of the new and literature records, the potential distribution of the species was modelled with ecological niche modelling. The main factors affecting the distribution of the species are the annual mean temperature (bio1, 55.3%), precipitation of driest month (bio14, 18.5%), and annual precipitation (bio12, 10.1%) and account for 84% of the distribution model. © Biharean Biologist, Oradea, Romania, 2016.Öğe Observation on defensive behavior of two salamandrids: Ommatotriton vittatus (Gray, 1835) and Triturus ivanbureschi Arntzen & Wielstra, 2013(Editura Universitaria Craiova, 2019) Yakin, Batuhan Yaman; çiçek, Kerim; Afsar, Murat; Tok, Cemal VarolAmphibians developed various defensive strategies in order to be protected from predators and increase their survival success. One of these behaviors is called "immobility", in which during threat of predator attacks, amphibians stand still and then curl their tails and heads inward to show the "threatening" body coloration to the predator. Here, we report two cases of defensive behaviours in Southern banded newt from Mersin (Southern Anatolia) and Balkan crested newt from Manisa (Western Anatolia) under terrestrial stages. © 2019 Editura Universitaria Craiova.Öğe On the Eumeces schneiderii (Daudin, 1802) (Sauria: Scincidae) specimens collected from Northeastern Anatolia, Turkey(Universitatea din Oradea, 2014) Afsar, Murat; Tok, Cemal Varol; Çíçek, KerimIn this study, the specimens of Eumeces schneiderii obtained from the vicinity of Aralik (Igdir) and - for the first time - Digor (Kars) in North-eastern Anatolia were examined morphologically and compared with the literature concerned. According to the obtained results, the specimens under examination resembled subspecies pavimentatus in terms of some characters, whereas they were considered to be E.s.cf. princeps as they were closer to subspecies princeps in terms of the leg index (LI), the number of scales at the mid-body (ScDM), the mean number of scales around (encircling) the left parietal plate (ScP-left) and colour-pattern characteristics that were important in terms of the discrimination of subspecies. © Biharean Biologist, Oradea, Romania, 2014.Öğe Population estimate and body size of European pond turtles (Emys orbicularis) from Pazaragac (Afyonkarahisar/Turkey)(Walter De Gruyter Gmbh, 2007) Ayaz, Dincer; Fritz, Uwe; Tok, Cemal Varol; Mermer, Ahmet; Tosunoğlu, Murat; Afsar, Murat; Cicek, KerimData on population size, adult sex ratio, body size and mass are provided for a population of the turtle Emys orbicularis near Pazaragac (Afyonkarahisar/Turkey). Using the mark-recapture method (triple catch), a population size of 664 turtles was estimated (95% confidence interval, range 332-996), corresponding to a density of 83 turtles per hectare (range 41.5-124.5). The adult sex-ratio was significantly skewed in favor of males (2.02 males: 1 female; P < 0.001). Almost all recorded specimens were adult (98.1%). Mean straight carapace length (SCL) and body mass (BM) of adult turtles were: SCL = 128.65 mm, BM = 345 g for males (n = 168) and SCL = 135.37 mm, BM = 463 g for females (n = 83).Öğe Population size of the marsh frog (Rana ridibunda Pallas, 1771) in Lake Yayla (Denizli, Turkey)(2007) Ayaz, Dinçer; Tok, Cemal Varol; Mermer, Ahmet; Tosunoğlu, Murat; Afsar, Murat; ÇiÇek, KerimThe population size of marsh frogs (Rana ridibunda) was estimated using the mark-recapture method in Lake Yayla (Buldan, Denizli, Turkey). According to the results, the mean estimated population was 14,733 and the sex ratio was female biased (male: female, 0.56). The main limiting factors of the marsh frog population are also outlined. © Tübitak.Öğe The herpetofauna of the Sultan Mountains (Afyon-Konya-Isparta), Turkey(Tubitak Scientific & Technological Research Council Turkey, 2011) Afsar, Murat; Tok, Cemal VarolIn this study, 29 reptile and amphibian species were recorded in 25 different localities in the Sultan Mountains.
