Dispersal of Exotic Species in the Great Lakes: Crayfish as a Model System for Benthic Species

Major Goals and Objectives

  • Reconstruct the chronology of invasions of Orconectes rusticus and other nonnative crayfishes into the Great Lakes
  • Use genetic analyses of the regions in Lake Michigan where O. rusticus is displacing O. propinquus
  • Predict the future distribution of O. rusticus in the Great Lakes by comparing the environmental requirements of O. rusticus (especially substrata) with the characteristics of Great Lakes littoral zones
