In the Petrovaradinski Rit marsh region, the composition, dynamics, and importance of the food components of three syntopic anuran species of the genus Pelophylax were analyzed through all the seasons of their activity in order to determine the vulnerability of each species in the trophic competition. The results of the studies have shown that the trophic niche breadth, according to the importance index of contents, was the smallest for the species Pelophylax kl. esculentus and largest for the species Pelophylax ribibundus, meaning that the species Pelophylax kl. esculentus has the most uniform diet and is therefore most vulnerable to competition by other species.
