Abstract

Life history traits of the Yellow-bellied Toad, Bombina variegata (LINNAEUS, 1758), were studied in a population from Enez (Edirne, Turkey) applying skeletochronological techniques to phalangeal bones. In the adult sample (21 males and 22 females) age ranged from two to eight ((x) over bar= 4.35) years. The age at sexual maturity was one to two years. There was a positive correlation between body size and age for both sexes. Sexual size dimorphism was weakly expressed by the slightly bigger snout-vent-length of the females (SDI = 0.04). The growth coefficient (k) was bigger in males than females (k +/- Confidence Interval; males: 0.47 +/- 0.05, females: 0.34 +/- 0.02). There was no difference in growth rate between sexes. The non-significant difference in the size of male and female individuals from Enez may be related to similar longevity, age at maturity and growth rates of both sexes.
