Abstract :	Freshwater bivalves, which are among the most threatened animals in North America, present significant challenges to conservation biologists that attempt to maintain ecological and evolutionary processes within and among populations. Effective management of this rare fauna is often complicated because inadequate information exists for identification of species, subspecies, or distinct population segments. Information regarding basic biology including population structure, host fish identification, and general habitat requirements of the green floater (Lasmigona subviridis) was identified as an acute research need by Region 5, U.S. Fish and Wildlife Service (FWS). To provide the information needed to assess the species status and implement biologically sound management programs, a thorough understanding of the evolutionary relationships among geographic populations of L. subviridis is needed.
