| Description | Kairomones from juvenile perch (Perea fluviatilis) enhance phototactic descent of Daphnia to the hypolimnion of lakes following upon light intensity increases at dawn. Kairomones are not present in the hypolimnion and ascent in the evening might be insufficient for the animals to reach the epilimnion again. The hypothesis that sensitization is maintained for some time in the absence of fish exudates was tested. Experiments showed that sensitization was indeed maintained for 5–6 days. Thus a kind of “memory” for fish kairomones exists, resulting in an enhanced ascent from a fishless hypolimnion at sunset. Book Name: Zooplankton: sensory ecology and physiology |
