| Abstract |
|
We used mark-recapture techniques to study survival rates of Emys orbicularis in the Borowiec Nature Reserve (Central Poland, Radom district). About 40 adult and 20 young (3–9 years old) turtles live there. Mean straight carapace length (SCL) and body mass (BM) of adult individuals were respectively: SCL = 163.5 mm, BM = 0.67 kg for males (n = 14) and SCL = 181.8 mm, BM = 0.97 kg for females (n = 21). Based on scute growth rings we estimated that males mature on average with 11 years and females with 15 years. The youngest gravid females were 12 years old. Mean annual survivorship was close to 1.0 for adult turtles, and around 0.8 for young individuals.
