Five tests for recent population expansion in all nominal subgroups (as identified in Fig.3 and Methods, except Basal Pbar N. and S. are here combined, see Results).

Significant values are marked in bold with an asterisk (P < 0.05). For D, Fs, and R2, significance indicates a deviation from neutrality and support for a hypothesis of population expansion. For SSD and RI, significance indicates a deviation from the estimated model of demographic expansion based on mismatch analysis; thus, nonsignificant values indicate support for population expansion. R2 was calculated in DnaSP; all other statistics were calculated in Arlequin (see Methods).
