    A skeletochronological study of age, growth and longevity in two freshwater turtles, Emys orbicularis and Mauremys rivulata from Mediterranean Turkey (Reptilia: Testudines).

    We 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.

    Skin Pigmentation of Stellagama stellio (L. 1758) (Reptilia: Agamidae) Depends on Climate Conditions and Altitude
    (2017-09-01) Çiçek, Kerim; KUMAŞ, MELTEM; Ayaz, Dinçer; KUMAŞ, MELTEM
    We studied skin pigmentation characteristics of the starred agama, Stellagama stellio, at different altitudes and climate conditions from Anatolia, Turkey. The epidermis was composed of stratum corneum and stratum basale, while the dermis occupied a much larger area. Melanophores were only found in the dermis and melanin pigments exhibited different distribution patterns in cells. Our results indicated that the skin pigmentation of S. stellio varied among populations depending on the altitude and climatic conditions. At higher altitudes, the melanophores in dorsal skin were larger and its melanin pigments aggregated in melanophores. The aggregation of the melanin pigments indicated the skin had lighter colour. The melanin pigments tended to be dispersed at lower altitudes. The skin of populations inhabiting hot climates and lower altitudes was more pigmented, while populations from steppe and higher altitudes exhibit lower pigmentation when comparing melanophores areas.

    Age, Growth and Longevity of Kotschy-s Gecko, Mediodactylus kotschyi (Steindachner, 1870) (Reptilia, Gekkonidae) from Central Anatolia, Turkey

    We 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.
