Abstract

We studied 84 specimen of the green frog complex (Pelophylax esculentus complex) caught in the area of Bjelovarsko-Bilogorska county, in the period from May 2nd until May 6th 2007. We isolated the stomach content and one femural bone from each individual. The purpose of the study was to determine the content of the diet and to do the age analysis of each species within the P. esculentus complex. Also, we wanted to determine the age at maturity for each P. esculentus complex species. Results showed that all three species base their diet on the prey from the class Insecta. The youngest individuals (two years) belong to the P. kl. esculentus and P. lessonae species while the oldest individual (13 years) belongs to the P. ridibundus species. The latter species reach sexual maturity by the age of 3 to 4 years. This study highlights the differences among P. esculentus complex species.
