Popis: The spatial distribution of zooplankton communities in part of the Volga River (the Cheboksary and Kuibyshev reservoirs), including areas with different hydrological conditions, has been analyzed. The zooplankton composition and species structure gradually changes along the river profile. Littoral communities from different parts are more similar between themselves than with pelagic ones. In the river mouth zone of the tributary, the ecotone effect is manifested as fauna mixing, but not as an increase in species richness. Variations in the community structure are mostly determined by depth and water temperature.
