What can we learn from Daphnia filtering screens?

Received on December 21, 1997; accepted on April 3, 1998 The relative filtering setae length (RFSL the length of filtering setae on the third pair of thoracic limbs expressed as a per cent of carapace length) was determined in three developmental categories of a reservoir population of Daphnia galeata and its relationship to phytoplankton fluctuation. RFSL of adult females immediately after moulting reflects the current food conditions in the reservoir (higher RFSL at lower food level, and vice versa), whereas RFSL of adult females close to moulting reflects the food conditions several days or weeks ago. RFSL of juvenile animals reacts the most quickly to changing food conditions, provided the temperature allows frequent moulting. Higher RFSL can also indicate poor-quality food for daphnids, in situations when food quantitative parameters (such as chlorophyll a) show high values.
