Abstract

The results of the investigation of zoobenthos and zooperiphyton in two rivers in the basin of the middle reach of the Ob River are presented. Comparative analysis of two ecological groups of hydrocoles in zoobenthos and zooperiphyton showed differences in their taxonomic composition and dominating complexes. The similarities in total abundance and biomass of zoobenthos and zooperiphyton in a large river were detected, and higher values of the quantitative development of zooperiphyton in the medium river were observed.
