Öğe A skeletochronological study of age, growth and longevity in two freshwater turtles, Emys orbicularis and Mauremys rivulata, from Mediterranean Turkey (Reptilia: Testudines)(Taylor & Francis Ltd, 2016) Çiçek, Kerim; Kumaş, Meltem; Ayaz, Dinçer; Tok, Cemal VarolWe estimated growth parameters of Emys orbicularis and Mauremys rivulata in Mediterranean Turkey with the skeletochronological method, using specimens drowned in fyke nets. In adult E. orbicularis, the median age was 8 years in males and 10 years in females. The median age of adult M. rivulata was 10 years for both sexes. Both species reach sexual maturity at an age of 5-7 years. No difference was found in age composition between the sexes.Öğe Conservation activities for European pond turtles (Emys orbicularis) in Turkey(2013) Ayaz, Dinçer; Çiçek, Kerim; Tok, Cemal Varol; Mutlu, Hasan Serdar; Cumhuriyet, O?uzkan; Bayrakci, Yusuf; Kumaş, Meltem[No abstract available]Öğe Preliminary data on the age structure of Phrynocephalus horvathi in Mount Ararat (Northeastern Anatolia, Turkey)(2012) Çiçek, Kerim; Kumaş, Meltem; Ayaz, Dinçer; Tok, Cemal VarolIn this study, the age structure, growth and longevity of 27 individuals (8 juveniles, 8 males and 11 females) from the Mount Ararat (I?dir, Turkey) population of Phrynocephalus horvathi were examined with the method of skeletochronology. According to the obtained data, the median age was 3.5 (range= 2-5) for males and 4 (2-5) for females. Both sexes reach sexual maturity after their first hibernation, and no statistically significant difference in age composition was observed between the sexes. According to von Bertalanffy growth curves, asymptotic body length was calculated as 51.29 mm and growth coefficient k - 0.60. © Biharean Biologist, Oradea, Romania, 2012.
