Diverse taxa of freshwater zooplankton can use chemical cues            to discriminate between particles which differ in food value.                   Thus, many planktonic grazers may be more specialized in                        theirdiets than previously suspected.  This research will use                   foodselection experiments, gut analysis, and field                              enclosureexperiments to investigate patterns and strategies of                  chemically.mediated selection, and to evaluate the importance of                thisphenomenon in a natural community.                                                  Foraging theory predicts that decision-based selection                  behavior should be sensitive to nutritional quality, the                        abundance of alternative foods, and hunger.  These predictions                  will be tested with copepods feeding in natural seston.                         Enclosure experiments will be used to test for differences                      between taste-sensitive (Diaptomus) and nondiscriminating                       (Daphnia) grazers in their impacts on natural phytoplankton,                    bacteria, and detritus.  In addition to these basic research                    objectives, undergraduate involvement through the Crooked Lake                  Biological Station is a major asset of the project.
