| Abstract |
|
Emys orbicularis was studied 1999–2004 in the Kharkiv region of Ukraine. There, it inhabits oxbows, main riverbeds, springs, swamps, and artificial ponds. Egg-laying takes place at the end of May to the middle of July. The majority of nesting sites are situated on sandy terraces of rivers, on southfacing slopes with steppe-meadow vegetation. The most frequent clutch size is 9–11 eggs but it varies from 6–22 eggs (maximum for Ukraine). Hatchlings migrate to permanent water bodies in autumn or the next spring following terrestrial hibernation. Post-mortem examination of migrating hatchlings in spring revealed the presence of terrestrial insect remains in their digestive tracts.
