Abstract
The relationship between the birthrate and biomass of different-group phytoplankton was analyzed during the summer for Daphnia cucullata and Bosmina logirostris in the mesotrophic Drysviaty Lake. The high cross-correlation coefficients were obtained for the birthrate and phytoplankton with a size from 5 to 20 µm. There is no correlation between the birthrate and seston with a size of ≤50 µm. Our results suggest that the total biomass of phytoplankton and seston do not reflect the food availability of cladocerans.
