Models are ranked by differences in Akaike’s information criterion and only candidate models within ΔAICc d ≤ 4.0 are presented. Model selection results are followed by model averaging results for each species. The R2 represents the model fit for the estimated spatial occurrence vs. model averaged predicted values.
