Lake Michigan is being invaded by a predator new to the                 Nearctic.  Bythotrephes cederstroemii, was first found in the                   Laurentian Great Lakes in December, 1984.  By August 1986, the                  species had spread to Southern Lake Michigan, and was doubling in               abundance every 10 days.  Bythotrephes is invading aggressively,                particularly in the offshore region, but is so far avoiding                     habitats occupied by glaciomarine relict species.  As an invading               plankton species joining an existing community, it represents a                 rare opportunity to study manipulation of a food web at the                     middle trophic level.  Judging from its persistence and success                 in deep European lakes, Bythotrephes will probably become a                     permanent member of zooplankton communities in the Nearctic.                                                                                                            This proposal seeks to study the trophic dynamics of this               community-level perturbation across the physical and ecological                 gradients between inshore and offshore regions.
