Abstract

As a consequence of their evolutionary diversity in form and function the protista of aquatic ecosystems exhibit a great variety of complex trophodynamic interactions, which confounds attempts to produce gross estimates of their in situ feeding rates. It is our view that studies of trophic behaviour at species and taxon level and quantification of community ingestion rates, are needed to develop an understanding of how food webs operate. New behavioral observations (e.g. veil/pallium feeding in dinoflagellates, Gaines and Taylor 1984, Jacobson and Anderson 1986, or small, aloricate planktonic ciliates feeding on bacteria, Sherr and Sherr 1987) suggest possible directions for future quantitative studies.
