Geographic variation in host fish use and larval metamorphosis for the endangered dwarf wedgemussel
Abstract Host fishes play a crucial role in survival and dispersal of freshwater mussels (Unionoida), particularly rare unionids at conservation risk. Intraspecific variation in host use is not well understood for many mussels, including the endangered dwarf wedgemussel ( Alasmidonta heterodon ) in...
