The effect of temperature and viscosity on the ingestion rate of Daphnia galeata and Chydorus sphaericus was investigated in short-term feeding experiments with 3H-labelled Scenedesmus quadricauda. Viscosity was manipulated independently from temperature by addition of inert polymers in two experiments. In the first experiment, the ingestion rate of D. galeata was found to be 50% lower at 10°C than at 25°C due to the combined effects of increased viscosity and lower temperature. Viscosity alone… CONTINUE READING
