Models are ranked using the bias-corrected Akaike Information Criterion (AIC_c) and the best approximating model for each species is shown in bold. Only the models included in the 95% confidence set for the best model of each species are shown. ∆_m is the difference in AIC_c units between a model m and the top ranked model; w_m is the AIC_c weight of model m; log(L) is the model log-likelihood; and K is the number of estimable parameters in the model. All fitted models included a random effect of individual on the intercept (term is not shown in the table). The term mflow denotes mean daily flow.
