| Abstract |
|
The European pond turtle lives in small, scattered and isolated populations of lowland Poland. Females are bigger than males - the mean straight carapace length (SCL) measures 183 mm (170.3 - 200.1 mm) and 172 mm (159.0 - 186.6 mm) respectively for females and males. Emys orbicularis is active from the end of March to the beginning of September. The mating period lasts from the end of April to the first days of May. Oviposition occurs between the third decade of May to the middle of June. Females lay 7 - 2 3 eggs (mean 14.4) once a year. Eggs weigh 8 - 10 g and mean egg size measures 32.7 x 20.8 mm. Young turtles (SCL = 23.3 - 28.8 mm, body mass 3.7 - 6.1 g) hatch in the second half of August or September. Hatchlings emerge from nests from August until October or overwinter occasionally
