Taxonomic diversity of the dominant cyanobacteria species during blooms in water bodies of Russia

An analysis of information about the dominant cyanobacteria taxa during cyanobacterial blooms in the largest water bodies of Russia during the summer period was carried out. As a result, 32 species of cyanobacteria belonging to 17 genera were shown to be among the dominant species in inland water bodies. Of these, Aphanizomenon flos-aquae, Microcystis aeruginosa, Dolichospermum flos-aquae and Dolichospermum lemmermannii were the most frequently encountered taxa during blooms. In marine systems, representatives of 12 species belonging to 9 genera were observed. Among them Aphanizomenon flos-aquae, Trichormus variabilis, Dolichospermum flos-aquae, Microcystis aeruginosa and Nodularia spumigena were the most common. It is noted that Aphanizomenon flos-aquae, Microcystis aeruginosa and Dolichospermum flos-aquae have the widest distribution over the territory of Russia and are found both in water bodies of the Arctic zone of the Russian Federation and the south of the country, as well as in the distributed parts of coastal seas, while Dolichospermum lemmermannii is more typical of water bodies located in regions with subarctic or boreal climate, and is not found as a dominant in regions with temperate climate.
