Population genomics of four co-distributed frog species in a barrier island system

We sequenced new genome-wide sequence data (double digest restriction site-associated DNA sequencing) for four frog species (Anaxyrus terrestris, Hyla cinerea, Hyla squirella and Rana sphenocephala) sampled from two barrier islands and the adjacent mainland of northern Florida. We calculated genomic diversity metrics and analyzed spatial patterns of genomic variation for each species.
