- Sample sizes and coalescent simulation results for Fu’s FS, R2, Harpending’s raggedness index (r), and mutation time parameter τ calculated from a sudden-expansion demographic model. Multiple tests supported population expansions for each group of populations (boldface); one test supported a population bottleneck (underlined). Population expansion dates (thousands of years ago, ka) were estimated from τ using a per-locus mutation rate (μ = 8.12 × 10-6) converted from the BEAST cytb estimate. Regional results are only presented for regions with no SAMOVA-inferred subdivision. Brackets contain 95% confidence intervals; ns, not significant; **P < 0.0001 (P < 0.02 for Fu’s FS).
