Neither is the action of invertebrate predators. The results, obtained from the study indicate that the possible causes of changes in the zooplankton numbers, biomass and structure should be found on the one hand in changes in the size structure and biomass of the phytoplankton, and on the other – in the nature of the relationship between the phytoplankton and zooplankton.}, type={Text}, title={Pelagic zooplankton (Rotatoria + Crustacea) variation in the process of lake eutrophication. 2, Modifying effect of biotic agents}, URL={http://rcin.org.pl/Content/70171/PDF/WA058_87285_P2840-T33_Eko-Pol-A-Nr-4.pdf}, volume={33}, number={4}, journal={Ekologia Polska}, publisher={Polish Scientific Publishers}, keywords={lakes, zooplankton, Rotatoria, Crustacea, eutrophication, zooplankton grazing, invertebrate predators, fish pressure}, }
