Each column reports the percentage of total nodes (second column) that fall into the following categories: (a) concordant nodes are those present in the combined-data tree that are also present in both mtDNA and nucDNA trees; (b) discordant nodes are absent in one or both of the trees from the separate data sets; (c) strongly supported discordance indicates branches for which conflicting resolutions in mtDNA and nucDNA are strongly supported (Pp ≥ 0.95) by each one; (d) weak mtDNA (or nucDNA), strong nucDNA (or mtDNA) indicates branches for which conflicting resolutions were weakly supported by one (mtDNA or nucDNA) and strongly supported by the other; (e) weakly supported discordance indicates branches for which conflicting resolutions in mtDNA and nucDNA are weakly supported by both; (f) the far-right column gives the proportion of nodes with strongly supported discordance that are resolved in favor of the mtDNA in the combined-data tree. P-values indicate whether the number of these resolutions favoring mtDNA data are significantly different from random (exact binomial, p = 0.50). Significant P-values are bold faced.
