Univariate measures of phylogenetic signal for log10-transformed traits in the dataset.

K varies from 0 to 1 to >1, indicating, respectively, no phylogenetic signal, that relatives resemble each other as much as expected under Brownian motion–like evolution, and that relatives are more similar to each other than expected under Brownian motion [7]. P-values indicate significant phylogenetic signal based on randomization tests of the mean squared error. Results are from the Picante package in R [34], [35] utilizing the phylogeny presented in [1] with all = 1 branch lengths.
