| Abstract: | Preferential feeding behaviour by Daphnia magna was shown when Daphnia were fed on a mixture of 14C-labelled algae (Chlorella vulgaris or Scenedesmus quadricauda) and 3H-labelled bacteria (Escherichia coli). Daphnia consumption of bacteria was equal or higher in the presence of algae. On the other hand, in the presence of bacteria, algal consumption decreased by 40–70% compared to algal consumption in the absence of bacteria. 14C radioactive uptake was in good agreement with the chlorophyll content and demonstrates the preferential feeding behaviour of Daphnia. |
