N = number of sequences, h = number of haplotypes, S = segregating sites, θW = population mutation rate per site, π = nucleotide diversity per site, DT = Tajima’s D statistic [73]. An asterisk (*) in the DT column indicates a significant deviation from the expected value under neutrality (DT = 0) as calculated from coalescence simulations. DT values in bold obtained for P. jubatus when the divergent sample UVC15842 was excluded. N.A. = Not Applicable. Indels and sites with missing data were not taken into account in pairwise comparisons.
