A laboratory study of functional response of <I>Leptodora kindtii</I> to some cladoceran species and copepod nauplii.

Original language description

Feeding of the predatory cladoceran <I>Leptodora kindtii</I> was studied under laboratory conditions. Functional responses for two size classes of the predator to five prey taxa (<I>Daphnia galeata, Diaphanosoma brachyurum, Ceriodaphnia pulchella, Bossmina coregoni</I> and copepod nauplii) in five prey concentrations were determined and further analysed. Small juvenile <I>Leptodora</I> showed a Hollings' type I functional response in all five experiments, whereas large adult <I>Leptodora</I> showed in 3out of 5 cases a Hollings' type II functional response. The possible significance of these differences is discussed. For all prey categories, the ratio of the basket length of <I>Leptodora</I> to the prey body length considerably influenced maximum predation rates. Prey taxa show different vulnerabilities for predation by <I>Leptodora</I>, hence, during periods of abundance this predator may have a significant structuring effect on the zooplankton community.
