RT Journal Article SR Electronic T1 Genomic data reveal similar genetic differentiation between invertebrates living under and on a riverine floodplain JF bioRxiv FD Cold Spring Harbor Laboratory SP 044073 DO 10.1101/044073 A1 Steve Jordan A1 Amanda DelVecchia A1 Brian K.

Here we offer RAD-seq data to show that levels of connectivity of a winged stonefly with groundwater larvae and an obligate groundwater amphipod show similar levels of connectivity between floodplains separated by 40 km in the Flathead River basin of NW Montana, USA. This may be due to deep phreatic water connections that enhance movement of organisms between these populations.
