Our paper on phylogeography of skinks was just published in the Biological Journal of the Linnean Society! This research was a collaboration between myself, Jeff Streicher, and researchers at the University of Texas Arlington. We analyzed a dataset of both mitochondrial and nuclear loci to show that there has likely been mitochondrial introgression between two skink species (Plestiodon multivirgatus and Plestiodon tetragrammus), but that this introgression only occurred in one geographically delimited lineage of P. tetragrammus. This introgresson had downstream impacts on molecular evolution for each clade, and we used this dataset as an opportunity to talk about how geography can shape the opportunity for hybridization and hencethe impact on patterns of molecular evolution.
