Bayesian reconstruction of ancestral metamorphic timing in plethodontid salamanders. Four ordered metamorphic age categories (0 to 11 months, 12 to 23 months, 24 to 35 months, and 36 months or more) were reconstructed in BayesTraits. Pie diagrams at each node show the proportional probability (prob.) of each state, and the highest probability subtends above the branch at each node. Continuous reconstruction of minimum metamorphic age under Brownian Motion was also performed in BayesTraits and the average age, from 4 million post-burnin generations, subtends each node below the branch. The phylogeny is based on Bayesian analysis of Rag1 sequences in BEAST.
