Note:
These predictors are proxies of different hypotheses grouped into three categories (sensu Pontarp et al., 2019). Also shown are their level of collinearity (variance inflation factor, VIF), variable importance according a conditional random forest analysis and their phylogenetic signal (Blomberg’s K). Statistically significant results and their respective p-values are shown in bold.
