Abstract
The zooplankton of the floodplain reservoirs of the Middle Ob, located at various distances from the main channel of the river, has been studied. It is shown that, in floodplain reservoirs, the development of the summer zooplankton complex begins simultaneously with the passage of the flood; in the summer months, the greatest species diversity and the highest biomass are noted in them. The more often a reservoir is filled with high waters, the higher the species diversity and abundance of zooplankton in it. Factors have been identified that statistically significantly determine the development of zooplankton in floodplain reservoirs: frequency of flooding, water temperature, content of organic substances, and (for a number of taxa) gas regime. It is confirmed that the zooplankton of floodplain reservoirs differs significantly from the communities of the mother river and from the lakes of the terrace above the floodplain in significant faunal diversity, increased species richness, and specific species structure.
