Environmental variables explaining the global distribution of the most frequent fungal taxa. a Random forest model performance for 457 fungal taxa where out-of-bag R² > 0. b Contribution of climatic, soil and vegetation variable categories to the variation explained by the complete random forest model for each fungal taxon. c Importance of individual environmental variables across models for all fungal taxa showing raw variable importance and variable importance weighted by out-of-bag R² for each taxon
