Myself, along with my advisor (Adam Leaché) and collaborators in Texas, Mexico, and Colombia, have just submitted a manuscript for review that examines the spatial and temporal extent of gene flow in the Sceloporus spinosus group. We have made the pre-print article available online at Biorxiv, and you can find the article here! If you have any questions on the manuscript or would like to see the supplemental files, let me know!
