Pleistocene speciation and isolation-by-distance within North American mud and rainbow snakes

Understanding phylogeographic structure is a key step in examining the processes related to lineage divergence and speciation. It is often expected that wide-ranging taxa will be composed of deeply divergent lineages and that codistributed species will have similar population genetic structure. Within the southeastern coastal plain of North America, a biodiversity hotspot, the evolutionary processes that have led to the accumulation of diversity are underexplored. Several process within this region could be responsible for species diversification, including past changes in climate, fluctuating sea levels, and the formation of river systems. However, it is also possible that a pattern of isolation-by-distance can explain population genetic structure found in widely distributed species, which can serve as a null hypothesis for observed genetic structure. We generate a reduced representation genomic dataset with population level sampling for two sister species of snakes endemic to the sout..., , README: Pleistocene speciation and isolation-by-distance within North American Mud and Rainbow snakes
