摘要

Data on the species composition, taxonomic structure, and quantitative indices of epiphytic algae development, and also on the peculiarities of their distribution on higher aquatic plants of various ecological groups occurring in the additional net of the Kanev Reservoir, have been generalized for the first time. A total of 216 species of algae represented by 224 infraspecific taxa, including those containing nomenclatural types of species, was found in the reservoir. Bacillariophyta, Chlorophyta, and Streptophyta were represented by the largest number of species. The distribution of epiphytic algae species over the plants belonging to various ecological groups was non-uniform. On submerged plants, the number of algal species was 1.4 times higher than that on half-submerged plants and 1.9 times higher than that on plants with floating leaves. On higher aquatic plants of various ecological groups, the quantitative indices of phytoepiphyton development also significantly varied. On submerged plants, the average numbers of phytoepiphyton were one order of magnitude higher than those on half-submerged and plants with floating leaves, whereas its average biomass was two orders of magnitude higher than that on half-submerged and plants with floating leaves.
