*p < 0.05; **p < 0.01; ***p < 0.001.Shown is (n), number of individuals; (h), haplotype diversity, (π), nucleotide diversity; (τ), mutational time since demographic expansion; (theta) the mutation parameter per sequence as observed and (theta₀) prior to expansion; TSE, Time since the last population expansion; (Tajima’s D), Tajima’s statistics (1989); (R²), Ramos-Onsins and Rozas statistics (2002); (F_s), Fu’s statistics (1997); (the estimated time since expansion is only given for those clades/taxonomic units with significant population growth identified by more than one method (Tajimas’s D, R², or F_s), using different divergence rates.
