Abstract

I describe the food and feeding habits of 61 adult palmate newts during their aquatic phase from three localities in NE Iberia. 1 used the stomach-flushing method to obtain the prey, of the newts with 100 % efficacy. Diptera were overall the most important prey of palmate newts. Diptera and Ostracoda were the main prey in two localities, but in the third locality only Ostracoda were the main prey. There was generally an interpopulation trophic segregation. Analyzing the data at different localities demonstrated trophic segregation at Serra de Daró and Canet d'Adri, while Podocopa dominated the diet at Fogars del Tordera.
