RT Journal Article ID 47070c8f2a81db8b A1 Gromova, Yu. F. T1 The Structure and Composition of Pelagic Communities of the Estuarine Region of the Vita River JF Hydrobiological Journal JO HYD YR 2001 FD 2001-02-01 VO 37 IS 1 OP 11 AB The structure and composition of phytoplankton, zooplankton, and fish fauna of the estuarine region of the Vita river were studied. It has been found that periodic fluctuations in the direction and velocity of flow essentially influence the formation of plankton communities. The maximum quantitative indices of development of the biota were registered in semi-flowing water bodies. On the whole, plankton of the estuarine region is more diverse in its species composition than that registered in the river taken alone, and also than plankton occurring in the adjacent sections of the Kanev reservoir.
