| Abstract |
Assemblages of algae with different concentrations of zooplankters were kept in cylinders suspended in the lake. Analyses of water and both groups of organisms were conducted inside and outside these aquariums. Rotifers exhibiting no consistent vertical migration decreased the daily photosynthesis of algae by 22%. Vertically migrating copepods and cladocerans exerted no significant effect on the photosynthesis. None of the animal groups influenced the photosynthetic efficiency of algae, their carbohydrate production per unit of chlorophyll. Photosynthesis and photosynthetic efficiency were increased several days after rainfall. (Author) |
