ABSTRACT

It has been analyzed the dynamics of phytoplankton development in three water bodies of the Dnieper tandem storage reservoir system for the period of 30 years. The comparisons showed that the intensity of water ‘bloom’ caused by blue-green algae (cyanoprokaryotes) was evidently higher, and this process was prolonged, in the years of lower solar activity. The ‘bloom’ intensity decreases in years of high solar activity (11-year cycle). Such effect is connected with the peculiarities in the structure and photochemical activity of pigment phothosystems in different taxonomic groups of algae.
