  1. The models are ranked by the AICc values from the best to the worst model. Predictor variable names (with the regression coefficient sign), adjusted R 2, number of estimated parameters (K), AICc values, AICc differences (Δ i ) and Akaike weights (w i ), are presented. Environmental variables included in models were: annual mean temperature (BIO1), temperature seasonality (BIO4), annual precipitation (BIO12), and the “Normalized Difference Vegetation Index” (NDVI)
