(p(SDD) = sum of square deviations; p(hg) = Harpending's raggedness index; Tajima's D (D) and respective p value; Fu's Fs test (Fs) and respective p value; Ramos-Onsis R2 (R2) and respective p value). Statistics that do not suggest range expansion are shown in bold font. Results for the spatial genetic structure estimated with GEODIS are also shown. Statistics that do not show evidence for spatial genetic structure are shown in italic font.

(a) Dataset using haplotypes inferred by PHASE with probability threshold > 0.60 (208 haplotypes)

(b) Reduced dataset using haplotypes inferred by PHASE with probability threshold > 0.90 (192 haplotypes)
