As compared to limnetic sites, the stations located in the lotic part of the reservoir were marked for a steadier course of zooplankton abundance dynamics, a smaller contribution of Crustacea to zooplankton, a smaller fecundity of the dominating crustacean species, but greater – of rotifers, a smaller share of plant food in zooplankton diet, a weaker pressure of invertebrate predators on small bodied zooplankton and about a two-time longer turnover time of total P and phosphorus contained in food in effect of phosphorus regeneration by zooplankton.}, title={Densities structure and the role of zooplankton in phosphorus cycling in limnetic and lotic parts of Zegrzyński Reservoir}, type={Text}, URL={http://rcin.org.pl/miiz/Content/81784/PDF/WA058_88120_P2840-T37_Eko-Pol-A-Nr-3-4.pdf}, volume={37}, number={3-4}, journal={Ekologia Polska}, publisher={Polish Scientific Publishers}, keywords={dam reservoir, zooplankton density, species structure and diversity, predator pressure, phosphorus regeneration, phosphorus sedimentation}, }
