Number of parameters
The greater number of optimal models selected by the EXP approach had a greater number of parameters among all the selection approaches for both fish and odonates (Figures 3e-f). Among the four sequential approaches, the ORTEST approaches selected a greater number of optimal models with a greater number of parameters over the AUCDIFF approaches (Figures 3e-f). But all approaches selected optimal models with the number of parameters greater than the number of occurrences used for model building for at least some species (Figures 3e-f). Optimal models chosen by the EXP approach had a statistically significant correlation for the number of parameters only with optimal models chosen by ORTEST_PER for fish (Table S4).
