Özet

The life-history traits of Podarcis siculus were studied by skeletochronology in a population inhabiting an altitude of 28 m a.s.l. in Filyos, Turkey. The mean age was 6.8 years while the minimum and maximum age ranged from 4-12 years in males and 4-10 years in femaleS, respectively. The mean age of the specimens was not significantly different between sexes. The age at sexual maturity was 2-3 years for both sexes. There was a significant positive correlation between snout-vent length (SVL) and age in males, while there was no correlation in females. A strong male-biased sexual size dimorphism (SSD) was observed in the population. For both sexes, the estimated asymptotic SVL was slightly lower than the maximum SVL. The recorded growth coefficient (k) was slightly lower in males than in females (k CI, males: 0.76 +/- 0.22; females: 0.94 +/- 0.22). There was no growth rate difference between both sexes (P = 0.594).
