Rivers can act as both islands of mesic refugia for terrestrial organisms during times of aridification and barriers to gene flow, though
evidence for long-term isolation by rivers is mixed. Understanding the extent to which riverine barrier effects can be heightened
for populations trapped in mesic refugia can help explain maintenance and generation of diversity in the face of Pleistocene climate
