λ represents the degree to which the covariation between the two variables is influenced by phylogeny. Significant relationships highlighted in bold. Multivariate analysis includes estimates of each independent variable’s importance for predicting the dependent variable using Akaike’s Information Criterion (with correction for small sample size, AICc) weight. Tables 2 and 3 display the same information for different sample sets.
