Altitudinal effects on the life history of the Anatolian lizard ( Apathya cappadocica , Werner 1902) from southeastern Anatolia, Turkey

Abstract

Altitudinal gradients are an important variable in testing the life history traits (e.g., longevity, age at maturity, and body size) of organisms. In this study, the life history traits of the Anatolian lizard Apathya cappadocica were examined from 3 populations from diferent altitudes (Kilis, 697 m; Şanlıurfa, 891 m; Diyarbakır, 1058 m) from southeastern Anatolia, Turkey. Age structure was determined by using skeletochronology. Males in all populations were the larger sex; therefore, the populations showed male biases that were negative by the sexual size dimorphism index. Males in Diyarbakır (high altitude) were also younger than males in the other populations. Tere were no signifcant diferences between the males and females of all 3 populations in terms of either age or snout– vent length except in the Şanlıurfa population, in which males were larger than females. Life history traits of A. cappadocica across altitudinal gradients may be afected by climatic factors, as males from the middle altitude population in Şanlıurfa, which inhabits a warmer and more arid environment, tended to be larger than males and females in Kilis and Diyarbakır.
