Summary of MCMCglmm models with frequency of EPP as the response variable and Log₁₀-transformed uropygial gland size, Log₁₀-transformed body mass and total number of nests per species sampled for EPP (N EPP) as explanatory continuous variables. The models assume Poison (Model 1) and Gaussian (Model 2) distributions and the random effect of phylogeny was tested for each of the 100 phylogenetic trees considered and assessed as heritability (h²). For each factor, we report the average of estimates, as well as the lower and upper values of the confidence interval (95% CI), which were calculated respectively on the lower and upper 95% credibility interval values of the estimates of the 100 models. We also report 95% CI of the 100 models (i.e., one for each of the phylogenetic trees considered) for pMCMC values, z-scores of the Geweke’s convergence diagnostic, effective sample sizes (ESS), and autocorrelations. Values in italics are statistically significant (pMCMC < 0.05).
