Abstract

The abundance of functional feeding groups and the species richness of macrozoobenthos are analyzed under different levels of anthropogenic pressure in the Neman River basin. The abundance of species in the different functional feeding groups significantly decreases for predators and active filter feeders at sites subject to anthropogenic pollution compared to the conditions of the absence of anthropogenic pressure. Changes in the species composition of some feeding groups, primarily predators, are identified under anthropogenic pressure.
