Abstract
Studies on phosphorus regeneration by zooplankton occupying the Krutynia River - lake Kujno transitory zone showed the zone to consist of three parts. In the first one, under strong impact of river waters, P regeneration rate was low and dominated by small, pelagic rotifers. Species diversity index calculated for phosphorus regeneration was also low. In the second part, densely covered with macrophytes, the role of large-bodied littoral zooplankton in P regeneration became more important and the rate of the process and species diversity index markedly higher. The third part, a type of littoral-pelagic belt, was characterized by the highest P regeneration and species diversity index and a relatively higher contribution of pelagic forms of zooplankton to the process of phosphorus regeneration.
