AB  - Little is known about the life histories, population connectivity, or dispersal mechanisms of shallow groundwater organisms. Here we used RAD-seq to analyze population structure in two aquifer species: Paraperla frontalis, a stonefly with groundwater larvae and aerial adults, and Stygobromus sp., a groundwater-obligate amphipod. We found similar levels of connectivity in each species between floodplains separated by ~70 river km in the Flathead River basin of NW Montana, USA. Given that Stygobromous lacks the aboveground life stage of P. frontalis, our findings suggest that aquifer-obligate species might have previously unrecognized dispersal capacity.
