T1 Seasonal Dynamics of the Quantitative Indices of Phytoplankton Development in the Upper Section of the Southern Bug River JF Hydrobiological Journal JO HYD YR 2014 FD 2014-10-31 VO 50 IS 5 SP 16 OP 26 K1 phytoplankton K1 numbers K1 biomass K1 seasonal dynamics K1 species number K1 dominant species K1 the Southern Bug River AB Seasonal dynamics of plankton algae species number, their numbers and biomass, and also of the complex of dominant species, were studied in the upper section of the Southern Bug River located within the territory of the town of Khmelnitskiy. Several peaks of algae development were revealed during the period of investigations. The highest number of phytoplankton species caused by a sharp increase in the number of green algae species was registered in July. The maximum numbers of phytoplankton conditioned by the development of blue-green algae were observed also in July. Seasonal dynamics of phytoplankton biomass were characterized by the presence of two peaks. The first peak conditioned by the development of diatoms was registered in June, whereas the second peak caused by intensive development of Dinophyta and Bacillariophyta − in September.
