ABSTRACT

Comparative analysis of the functional characteristics of phytoplankton of the Baikal and Khanka lakes, and also of the reservoirs of the Volga and Yenisey rivers, differing in their energetic and mineral resources has shown that their algae cenoses differ in the dimensional composition of dominant species. It has been found that the development of phytoplankton depends on the content of nutrients, its photosynthesizing activity - on the content of nutrients and light regime, whereas the intensity and relationship between the processes of production and decomposition - on hydrological conditions and morphometric peculiarities of water bodies.
