Abstract: | Life tables of Moina macrocopa (Straus) cultured at seven foodconcentrations (FC) (Scenedesmus sp., 1.49–1490 mg wet weightl-1, 104–106 cellml-1) were investigated for animals of the first generation(nonadapted animals) and for animals of the third generation (adaptedanimals) cultivated at these FC. Adapted animals showed a trophicpreferendum, i.e. a narrow FC-range at which maximal Rovalues were observed in comparison with nonadapted animals. In adaptedanimals, the maximal Ro was 115.3 individual, observed at 20°C and a FC of 74.5 mg wet weight l-1. |
