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 different 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. There were no significant differences 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 affected 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.
