Detection of outlier SNPs using Arlequin 3.5. Assuming a hierarchical model of migration and excluding Lake Clark populations. FST: locus-specific genetic divergence among populations; h0/(1 - FST): a modified measure of heterozygosity per locus. Dashed lines indicate lower and upper 95% confidence intervals for variation in neutral FST as a function of h0/(1 - FST). Filled circles represent candidates for selection; empty circles represent putatively neutral loci. Marker labels have been simplified (the prefix "One_" is missing).
