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 A preliminary study on micronuclei and nuclear abnormalities in the erythrocytes of some Colubrid snakes from Turkey(Universitatea din Oradea, 2014) Hayretda?, Sibel; Mert, Gürkan; Yakin, Batuhan Yaman; Tok, Cemal VarolThe mean micronucleated erythrocyte (MNE) frequencies and nuclear abnormalities in the peripheral blood erythrocytes of Coronella austriaca, Dolicophis schmidti and two Natrix tessellata specimens collected from Vize (K?rklareli), K?z?lcahamam (Ankara) and Digor (Kars) are reported for the first time in the present study. Different numbers of micronuclei were recorded in all snake specimens examined. In addition, three types of nuclear abnormalities were detected: nuclear bud, notched, and blebbed nuclei. The mean MNE frequency (%) was determined to be highest (0.300.08) in the N. tessellata specimen caught from K?z?lcahamam, the lowest (0.130.07) in the D. schmidti specimen caught from Digor. Nuclear abnormalities were encountered in different numbers in the specimens under examination. As a result of this examination on snakes inhabiting three regions of Turkey with different demographical and physical geographical characteristics (Thrace, Central Anatolia, and Eastern Anatolia), we conclude that similar genotoxic effects reported in the erythrocytes might occur widely due to environmental pollutant impacts. © Biharean Biologist, Oradea, Romania, 2014.Öğe A skeletochronological analysis of a population of the Anatolia Newt, Neurergus strauchii (Steindachner, 1887) (Caudata: Salamandridae), in Eastern Anatolia, Turkey(Taylor & Francis Ltd, 2015) Yakin, Batuhan Yaman; Cicek, Kerim; Koyun, Mustafa; Gurkan, Mert; Hayretdag, Sibel; Tok, Cemal VarolThis study presents data on age, growth and longevity of a population of Neurergus strauchii in Eastern Anatolia (Bingol, Turkey) based on skeletochronological data. The phalangeal diaphyseal cross-sections of 54 individuals studied (12o, 42f) showed that females are on average older than males: the ages ranged from 6 to 14 years, with an average age of 8.8 years in males and 10.9 years in females. Sexual maturity is reached at an age of 4-5 years in both sexes. The slow growth and the longevity make the species vulnerable.Öğe ABUNDANCE OF WESTERN CASPIAN TURTLE, Mauremys rivulata (VALENCIENNES, 1833) IN GOKCEADA (IMBROS), TURKEY(Folium Publ Co, 2016) Bayrakci, Yusuf; Ayaz, Dincer; Yakin, Batuhan Yaman; Cicek, Kerim; Tok, Cemal VarolIn this study, we present data on the population of Western Caspian Turtle, Mauremys rivulata, from Gokceada (Imbros) located at the westernmost of Turkey. The species is distributed almost all around the island, particularly in the western part, with a very low density. Distribution of the species on the island was mapped and a total of 73 individuals were captured and marked in Buyukdere, the largest river of the island. Population size was estimated at 135 individuals (SE - 11, range - 117 - 161) and density was calculated as 68 ind/ha. Moreover, Emys orbicularis, another freshwater turtle species, which cohabits in the west Anatolia, was observed again on the island after 15 years. Tourism, creeks with irregular flow regime and holding water in the dams negatively affect populations of aquatic species, primarily M. rivulata on the island.Öğe Age estimation of Anatololacerta anatolica (Werner, 1902) in the vicinity of Canakkale by skeletochronology(Tubitak Scientific & Technological Research Council Turkey, 2015) Yakin, Batuhan Yaman; Tok, Cemal VarolIn this study, age estimation using skeletochronology was done in 43 specimens (6 male male, 29 female female, 8 juv.) of Anatololacerta anatolica living in the vicinity of Canakkale. When the cross-sections taken from phalanges were examined, the median age for the Canakkale population was 4 years. The maximum age was calculated as 10 years for female individuals, and the maximum snout-vent length (SVL) of female individuals was measured as 74.18 mm. The mean SVL was 57.39 (SD = 4.6) mm for males and 63.62 (SD = 8.62) mm for females. The age at sexual maturity was determined as 3 years for both sexes of this species. As a result of correlation analysis, a strong correlation was found for both males (r: 0.845) and females (r: 0.886) in terms of age and SVL. These specimens were also examined for morphological properties and pholidosis characters.Öğe Herpetofauna of the Lake District around Burdur(Tubitak Scientific & Technological Research Council Turkey, 2015) Ege, Oguzhan; Yakin, Batuhan Yaman; Tok, Cemal VarolThis study investigated the amphibian and reptilian fauna of the Lake District around Burdur, Turkey. A total of 21 amphibian and reptile species were identified, consisting of two anurans, two turtles, one tortoise, seven lizards, and nine snakes. A zoogeographical assessment was also carried out in which the chorotypes and the IUCN criteria of the species were added.Öğe New records and rediscovery of some snakes from Gökçeada (Imbros), Turkey(Universitatea din Oradea, 2018) Yakin, Batuhan Yaman; Şahin, Utku; Günay, Ulvi Kerem; Tok, Cemal VarolIn this study, we rediscovered some snake species after quite a long time during the fieldwork in 2014 and 2015 on Gökçeada (Imbros). Natrix tessellata (Laurenti, 1768), which was found in Kaleköy, and Elaphe sauromates (Pallas, 1811), which was detected and photographed around the Education and Resting Association, Ministry of Justice, Republic of Turkey in the vicinity of airinköy, were new records for the island's snake fauna. All specimens except E. sauromates (Pallas, 1811), were found dead in the field. Morphological features of N. tessellata were examined in detail and results were compared with previous studies. Locality information and measurable and countable features of the other specimens are given. © Biharean Biologist, Oradea, Romania, 2018.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 Range extension and morphology of the Italian wall lizard, Podarcis siculus (Rafinesque-Schmaltz, 1810) (Squamata: Lacertidae), from Turkey(Tubitak Scientific & Technological Research Council Turkey, 2015) Tok, Cemal Varol; Cicek, Kerim; Hayretdag, Sibel; Tayhan, Yahya; Yakin, Batuhan YamanA record of the Italian wall lizard, Podarcis siculus (Rafinesque-Schmaltz, 1810), from Atakum (Samsun, Central Black Sea Region) is provided in this study. In addition, 5 specimens (3 male male and 2 female female) from Atakum (Samsun) and 14 specimens (7 male male and 7 female female) from Gelibolu (Canakkale, Thrace), with records provided recently, were evaluated in terms of measurements, pholidosis, and color and pattern. With the record from Samsun, the Italian wall lizard's distributional range has been extended about 360 km eastwards. The specimens examined from both localities were determined to resemble P. s. hieroglyphicus (Berthold, 1840), distributed in Thrace and Anatolia. Moreover, some information on the breeding biology of the specimens is provided.
