Age Structure and Body Size in a Turkish Population of the Green Lizard, Lacerta viridis (Laurenti, 1768)

Abstract

The present study was designed to obtain information about life history traits of Lacerta viridis in the Belen population with an altitude of 292 m. In the adult sample (21 males and 15 females), the age ranged from 3 – 10 (X = = 6.97) years for both sexes collectively, 5 – 10 (X = 7.43) years in males, 3 – 8 (X = 6.33) years in females and not differed significantly between sexes. Age at sexual maturity was 2 – 3 years for both sexes. However, a confirmation is required with some sexual characters (e.g., the presence of eggs for female, developed hemipenes for male) for age at sexual maturity in both sexes. The mean body size (SVL) was not significantly different between sexes. There was no correlation between SVL and age for males while there was a positive correlation for females. A male-biased sexual size dimorphism (SSD = 0.07) was observed in the population of L. viridis.
