AB: This study investigates two species of stoneflies with potentially opposing dispersal capabilities and genetic structure within four watersheds in the Lake Erie drainage system of Northeast Ohio. This research is two fold; it provides information on genetic variation of two understudied aquatic invertebrate species and the impact of human land-use practices on this variation. Populations of Allocapnia recta, a winter emerging stonefly are predicted to have the least genetic variation within the four watersheds and most differences among sites due to its rudimentary wing structure and winter emergence. Leuctra tenuis is predicted to have greater genetic variability within sites and fewer differences among sites because of its higher migration potential. In both species, models of isolation by distance will be tested. Distinct polymorphisms exist within the 16s rRNA region of A. recta suggesting that this fragment has sufficient variation to address these questions.
