Figure 1.

Combined-data Plethodon phylogeny. Phylogeny of the salamander genus Plethodon based on a combined, partitioned Bayesian analysis of mitochondrial DNA (mtDNA) and nuclear DNA (nucDNA). An asterisk next to a node indicates strong support (Pp ≥ 0.95). Small open circles on a node indicate Pp < 0.95, and these values are listed. Integers next to each node correspond to clade numbers used in analyses of congruence and discordance. A clade was not numbered if all terminal taxa belong to the same species. The outgroup taxa are excluded (but only from the figure) to facilitate presentation of branch lengths, and the root is indicated with a large open circle.
