Relative importance of climate and accessibility for species occurrences. [W, average (±s.d.) and median (minimum; maximum) summed Akaike weights for climate and accessibility. , average (±s.d.) and median (minimum; maximum) proportion of variation in species occurrences uniquely explained by climate or accessibility after controlling for the other factor. The values were either calculated across all species (n = 1016) or only for species with a positive model-averaged parameter accessibility coefficient (positive β_MA(A), n = 655).]
