ABSTRACT
We examined the food composition of the marsh frog, Rana ridibunda, populations inhabiting Turkey’s Lake District. Stomach contents of 82 (32 ♂♂, 50 ♀♀) adult individuals were investigated. It was found that the species mainly fed on invertebrates and especially on terrestrial preys belonging to arthropod groups (75.17%). The most frequently consumed preys with respect to numeric proportion were Diptera (19.85%), Coleoptera (12.72%) and Hymenoptera (10.02%). There are no differences in diet between sexes and among the populations examined.
