Table 2.
Parameter estimates and model fitting for multiple-rate Brownian models in Agamidae, where evolutionary rates are associated with inferred habitat use states. Values are means ± standard errors from model fitting across 500 reconstructions of habitat use on agamid phylogenies sampled from posterior probability distribution. Bold denotes the best fitting model.
