Figure 7

Underestimate of Bayesian branch lengths using empirical parameters. Percentage that branch lengths were underestimated for data simulated using empirical parameters for the mitochondrial genes atp6, cob, and cox3, as well as 3rd codon positions for all 13 mitochondrial protein coding genes on the plethodontid salamander phylogeny of Mueller et al. (2004). Data were analyzed in a Bayesian framework using MrBayes to determine the effects of biologically realistic, unequal branch lengths on branch length estimation. For clarity, only the mean underestimate for each branch across simulations is shown.
