Klymiuk V. Phytoplankton of salt lakes of Slovyansk

The dissertation's studies focuses on the phytoplankton of salt lakes of Slavyansk. A list of the species of lakes includes 336 species (350 species and intraspecific taxa) from nine divisions (Cyanoprokaryota, Euglenophyta, Chrysophyta, Dinophyta, Xanthophyta, Cryptophyta, Bacillariophyta, Chlorophyta, and Charophyta). An analysis of the community species composition shown, that factor of drying is more important than mineralization for the formation of the alga flora of those salt lakes. A bio-indication analysis was done for the first time. It was determined the present nontoxic impact of human on the lakes. The analysis of seasonal dynamics of quantitative characteristics showed that the peaks of algae were in the periods of reducing of salinity. Thus, salinity is negatively affected to the performance of ecosystems. It has been statistically confirmed bio-indication properties of some species in relation to chemical composition of water.
