  1. These analyses are based on 815 bp of CYTB. N number of individuals, S number of segregating sites, H number of haplotypes, Hd haplotype (gene) diversity ± SD, Pi nucleotide diversity (in%), k average number of nucleotide differences, θ Watterson’s estimate of theta (per site) from S, τ the parameter of onset of population expansion assuming the stepwise growth model (τ = 2 t*MU; t = time in years, MU = mutation rate per locus). Fu’s Fs significance p < 0.01 is marked by *, Tajima’s D significance p < 0.05 is marked by *, R2 significance p < 0.05 is marked by *, p < 0.01 by **.
