Much of the organic matter produced in lakes sinks to                   profundal sediments where it supports a community of benthic                    detritivores, often dominated by larvae of the Chironomidae.                    These insects (midges) are an important trophic link between                    phytoplankton and fish.  It is generally thought that lakes more                productive of phytoplankton will have higher secondary production               by this detritivore community, and ultimately by fish.  We do not               know how closely these ecosystem components are linked, nor do we               understand possible trophic and life history mechanisms for such                coupling.                                                                               This research asks whether production by profundal                      chironomids reflects the food supply to this community, or                      whether population densities are often too low to fully utilize                 available resources.                                                                    Pilot experiments will develop techniques for manipulating              food supply and larval recruitment to the profundal benthos to                  test hypotheses regarding factors that may limit profundal insect               production.  A model of secondary production by a dominant                      profundal species will also quantify the loss of production to                  fish through predation on ascending pupae.  This work will                      clarify the role of the profundal benthos in the trophic linkage                between primary production and fish.
