|
In 2006, 11 wild and 16 headstarted European pond turtles Emys orbicularis, that hatched in the years 1997–2001 and were marked during previous studies, were recaptured in central Poland. Wild turtles produced one growth ring per year, although variations were observed in headstarted individuals. Some headstarted turtles presented a pattern in which some of the growth rings were composed of false rings. Such a pattern was not observed in wild individuals. However, the growth ring pattern alone is not a reliable criterion for distinguishing between wild and headstarted turtles after being released into the wild.
