Table 2 Model averaging results for the best candidate models from QAICc-based (Quasi Akaike Information Criterion Corrected for small sample size) model selection (delta < 2) for large, small and all (pooled data) mammal species in Iran. Relative importance values represent the comparison of the contribution of each covariate in the original models and the simulated models. β is the estimated beta coefficient. Variable codes explained in Table 1.
