要約

A total of 227 taxa of free-living Ciliata was found in floodplain water bodies of the Dnieper reservoirs in 1982−1985. It has been found that pH of water essentially influences the quantitative indices of plankton Ciliata development. The highest quantitative indices of Ciliata development were observed in summertime in the water bodies of the first group. To specify the classification of the studied water bodies, the discriminant analysis of the quantitative indices of development of microinvertebrates of 6 groups was used. Nematoda and Rotatoria dominated in terms of the quantitative indices of their development. Among protozoo- and microzoobenthos, Ciliata predominated in terms of their functional significance. Ciliata, and Copepoda predominated in terms of their functional significance in periphyton.
