T1 Phytoplankton of the Lower Section of the Southern Bug River as the Index of Its Ecological State JF Hydrobiological Journal JO HYD YR 2016 FD 2016-09-30 VO 52 IS 4 SP 19 OP 31 K1 phytoplankton K1 numbers K1 biomass K1 chlorophyll a K1 nutrients, bioindication AB The present publication is a continuation of a cycle of publications dealt with the study of the ecological state of the Southern Bug River. Results of the study of the peculiarities of plankton algae development in the lower section of the Southern Bug River are given in the paper. Relationship between qualitative (species richness and diversity) and quantitative (numbers and biomass) characteristics of phytoplankton and the content of inorganic compounds of nitrogen and phosphorus in the water has been analyzed. The trophic level of the studied section of the river, and also the indices of contamination and river ecosystem state, was determined.
