A total of 82 specimens were collected (67 MM and 15 FF). From these we obtained 50 stomachal contents by using the stomach-flushing technique. From stomach contents analysis…
Is the painted frog Discoglossus pictus a declining species in Italy? On the reliability of a distributional atlas approach
