Title: Environmental factors influencing the feeding behavior of <i>Daphnia magna</i> Straus
Abstract: Feeding behavior of Daphnia magna on the food organism Saccharomyces cerevisiae, determined by electronic measurement of frequency of thoracic appendage movements (FTA), differs between groups cultured in lake, river, and dechlorinated tap water. FTA also varied between similar Daphnia cultured at different times in water collected from a common source. It is suggested that variability in water quality or physiological changes, possibly influenced by thermal history of the animal, alters feeding behavior. The concept of a "normal filtering rate" (McMahon and Rigler 1965) is reevaluated.
