^aJK-D denotes the mean value of Jackknife bootstrapping;

^bV(JK-D) denotes the variance of JK-D;

^cZ scores > 3 are considered significant evidence of a nonzero D-statistic value, consistent with the presence of admixture; given phylogeny (((P1, P2), P3), O)), positive D-statistic values are indicative of gene flow between P2 and P3; negative values are indicative of gene flow between P1 and P3

^dMch: M. itinerans var. chinensis, Mgd: M. itinerans var. guangdongensis, Mlc: M. itinerans var. lechangensis, Mit: M. itinerans var. itinerans, O: outgroup, M. basjoo
