Analysis of mitochondrial variability and historical demography. The number of sequences (N), number of haplotypes (h), haplotype (gene) diversity with one Standard Deviation (Hd), number of polymorphic (segregating) sites (S), nucleotide diversity (in %; with one Standard Deviation) (π), average number of nucleotide differences (k), Tajima’s D (with significance at P < 0.05 denoted by asterisk), Fu’s FS (with significance at P < 0.01 denoted by asterisk), Ramos-Onsins and Rozas R2 (with significance at P < 0.05 denoted by asterisk), onset of population expansion assuming the stepwise growth model (τ Arl, with 95% confidence interval), τ DnaSP (the moment estimator of time to the expansion), sum of squared deviations (SSD)and the probability of observing a less good fit between the model and the observed distribution by chance (P_SSD) and the mismatch observed mean (ObsMean)
