Clustering results for adaptation (among populations, Belize, Honduras, and Panama), speciation (among species, Hypoplectrus puella, H. nigricans, and H. unicolor, from Puebla et al. 2014), and simulated data (panmictic, migration rate m = 0.5, and structure, migration rate m = 0.02). In each case, the entire dataset (~40,000 SNPs) is presented above, followed by the SNPs above the 90^th F _st percentile, between the 80^th and 90^th F _st percentiles, between the 70^th and 80^th F _st percentiles, and between the 60^th and 70^th F _st percentiles (~8000 SNPs in each case).
