摘要

Contingencies of different components of freshwater biocenoses in the Don, Volga, Angara, and Northern Azov basins where studied by determination analysis. A positive contingency between the biomass of total phytoplankton or its divisions and the biomass of zooplankton was demonstrated. The most significant contingencies were revealed for zooplankton and green algae, dinoflagellates, and cyanobacteria. As against zooplankton, the biomass of zoobenthos features much less contingencies with the biomass of microalgae as well as zooplankton, since detritus, higher plant tissues, and small animals are the basis of the diet of benthic organisms. Differences in the contingency pattern between different geographical regions and time periods within the same basin have been revealed using the context procedure in determination analysis.
