Geomorphic influence on intraspecific genetic differentiation and diversity along hyporheic corridors

The hyporheic zone of rivers potentially acts as a dispersal corridor for groundwater organisms because it provides a spatially continuous interstitial habitat between isolated aquifers. Yet, the degree to which it can facilitate the movement of organisms has been hypothesized to vary in response to change in sediment regime, which determines channel morphology. In this study, we used microsatellite markers to test for a relationship between the...
