Appendix F. AIC table for the candidate multiple regression models.

Table F1. AIC table for the candidate multiple regression models. M stepAIC: model selected by the stepwise procedure. M total: model with all parameters (abiotic and biotic). M climatic: model with climatic factors only. M functional: model with functional factors only. AICc is the Akaike Information Criterion for small sample sizes, AIC is the Akaike Information Criterion, dAIC is the difference in AIC compared with the best model, and Weight is the Akaike weight (an absolute measure of support that sums to 1 across all candidate models).
