ABSTRACT

Data on species composition, distribution, and abundance of Cyanoprokaryota in plankton of rivers and lakes of the middle portion of the Irtysh River (Omsk Priirtyshye) are presented. A brief floristic analysis and the ecological and geographical characteristics of found species are given. In water bodies of the Omsk Priirtyshye cyanoprokaryotes have high species diversity and abundance. In the summer-autumn period water blooms caused by cyanoprocaryotes, including toxic species, were recorded in many reservoirs.
