| Popis: | Direct observations were used to study feeding by Daphnia longiremis Sars in the Kurile Lake (South Kamchatka) in terms of structural transformation of phytoplankton in 2008. Spectrum of the daphnia’s food reflects transformations in phytoplankton species structure. Daphnia’s consumption intensity of phytoplankton, where 99.8% were diatom cells, depends on the phytoplankton biomass. It is suggested, that daphnias meet deficient in food when the values of the phytoplankton (plankton diatoms) biomass are less than 48 mgС/m3 and no compensation of plankton bacteria or detritus. |
