  1. Models were ranked on the basis of ΔAICc, the difference in AICc points from the best model, and AICc weight, the probability of a model to be the best one. Models may or may not include a phylogenetic structure based on the Brownian motion BM model of evolution. When “BM” appears in the list of predictors, it means that phylogeny is affecting the relationship between organismal features and diversity variables; when “BM” appears alone, the model includes the sole intercept and phylogenetic structure. Estimates of significant regression coefficients are shown in parentheses.Only models with ΔAICc < 5 are shown.
  2. Best supported models (ΔAICc < 3) with no phylogenetic structure are indicated in bold.
  3. Peak-α elevation at which species richness peaks, Edf-α effective number of parameters of the smoothing function, Slopehab habitat turnover, Slopez elevational turnover, R2z magnitude of elevational turnover.
  4. ***P < 0.001, **P < 0.01, *P < 0.05, ·P < 0.10, generalised least square regressions. Sample size corresponds to the number of families, 14 of lichens, 9 of insects, 9 of birds.
