Sesonal dynamics of the phytoplankton and ecology of dominatil algaes in ponds, from the various degree of anthropogenous loading

The comparative analysis of seasonal dynamics of a phytoplankton in ponds, with various degree of anthropogenous loading is carried out. It is shown that in various ponds the course of seasonal dynamics is distinguished both under quantitative characteristics of development of a phytoplankton, and on structure of a dominating complex of species of algaes. In lake with low degree of anthropogenous loading in a phytoplankton during all season Chryzophyta, with high - smallcells Cyanophyta (on number) algaes, on a biomass - "casual" species prevailed.
