The effect of altitude, latitude and climatic variables on life-history traits of male Hyla savignyi (AUDOUIN, 1827) from Anatolia (Turkey): a skeletochronological study

Abstract

A total of 127 male individuals of Hyla savignyi (AUDOUIN, 1827) from three populations of different altitudes (Iskenderun - 10 m a.s.l., Sanlrurfa - 476 m, Igdir - 858 m) were studied for age structure and body size using skeletochronology. Due to the small number of females collected, only males were considered in the analysis. the oldest individuals were six years old, both in Sanlrurfa and Igdir, compared to five years in the Iskenderun population. Age upon attaining sexual maturity ranged from one to two years for all sites. Males from higher altitude and latitude populations were larger than individuals from low altitude and more southern populations.
