^aData from this study, concatenated matK and trnT-trnL-trnF data set, see Table 1.

^bData from this study, the autosomal Slop gene, see Table 1.

^cData from Ironside and Filatov (2005).

^dΦ is a fixation index similar to Wright's F statistics. It reflects the correlation of random pairs of haplotypes drawn from a group (species or race) relative to the correlation of pairs of random haplotypes drawn from the whole data set (Excoffier et al. 1992). Significance is indicated with stars: ***P < 0.001; **P < 0.01; *P < 0.05.
