Table 4 also shows that each gene region contributes positively to the overall support (sum of all branch support values) for the most parsimonious topology, with the mtDNA yielding the most (81.0%), followed by Ef-1(14.3%) and wg (4.7%). The mtDNA region provides the most support per nucleotide sequenced (0.61), followed by wg (0.22) and Ef-1 (0.20). The mtDNA region also provides the most support per informative site (1.71), followed by Ef-1 (0.86) and wg (0.59). Of the 101 resolved branches in the tree, mtDNA provides positive support to 88 and contradicts 9, Ef-1 supports 59 and contradicts 31; and wg supports 44 and contradicts 29 (15 taxa are missing the wg sequence). 25 branches are supported by all three gene regions, 23 by mtDNA + Ef-1, 11 by mtDNA + wg, 5 by Ef-1 + wg, 28 by mtDNA only, 5 by Ef-1 only, and 3 by wg only. Thus, although the mtDNA provides most of the phylogenetically informative characters, no single gene region drives the topology of the combined hypothesis of relationships, which is different from any of the trees implied by single genes analyzed separately (results from separate analyses not shown). Support and partition congruence for individual clades are discussed below. In the following paragraphs, numbers in parentheses after names of taxa refer to numbered clades in Fig. 2.
Figure 2. Single most parsimonious tree, length 10421 steps (CI x = 0.2110; RI = 0.5075). Clade numbers are indicated above branches. Corresponding branch support values, partitioned branch support values and partition congruence indices are presented in Table 5. Taxa are identified by name and voucher code. The tree is rooted with Tellervo.
