Results of the ecological analysis have shown that benthic and planktonic-benthic organisms were represented by the largest number of species. Algal species - indicators of slowly flowing and moderately warm waters, alkaliphiles and also indifferent organisms in relation to water salinity prevailed in epiphyton of the studied reservoirs. Among diatoms - indicators of the type of nutrition, nitrogen-autotrophic taxa tolerating elevated concentrations of organically bound nitrogen were represented by the largest number of species. Eurysaprobes and β-mesosaprobionts predominated among the indicators of organic contamination, whereas eutraphentic organisms - among the indicators of the trophic state. It has been found that in the Kanev Reservoir the contribution of eutraphentic organisms, nitrogen-autotrophic taxa tolerating elevated concentrations of organically bound nitrogen, and eurysaprobes was higher than that in the Kiev Reservoir. This fact is indicative of a higher degree of contamination of the Kanev Reservoir by nutrients and organic matter. %8 2019-08-09
