Neighbor-joining trees based on proportion nucleotide differences (Nei and Kumar 2000) for different single nucleotide polymorphism (SNP) sets: range-wide putatively neutral (a; N = 14,642) and autosomal candidate adaptive (b; N = 213). Clustering based on SNPs associated with significant GO terms: Epidermal Growth Factor (EGF)-like domain (c; N = 5) is illustrated with the first two principal coordinate (PCoA) axes. Points correspond to individuals color coded by currently recognized subspecies or population. Symbols other than circles (■ or ▲) highlight subdivision or less defined boundaries within subspecies. Support from 1000 bootstraps shown in Figs. B.6 and B.7. Branches with support from <700 boostraps were collapsed.
