Free-living Planktonic Infusoria of the Dnieper-Bug Liman and their Role in Production-destruction Processes

ABSTRACT

In the taxonomic composition of pelagic and benthic plankton of the Dnieper-Bug liman, 107 species and varieties of free-living infusoria were revealed. Their quantitative development and functional activity was estimated for different areas of the liman. The essential role of this ecological group in consumption of primary production and in destruction of organic substance is demonstrated. This activity decreased considerably in autumn.
