AUC test
A greater number of optimal models selected by the EXP approach for fish had a greater AUCTEST over other approaches, while for the odonates the ORTEST approaches had greater number of optimal models with greater AUCTEST followed by the EXP approach (Figures 3g-h). Overall the AUCTEST values of optimal models chosen by all five approaches were high (Figures 3g-h) except for one fish species Schizothorax progastus which had an AUCTEST value of .382 for the optimal models selected by ORTEST_PER and AUCDIFF_PER approaches (Figures 3g-h). There was also a high to very high statistically significant positive correlation for the AUCTEST among the optimal models chosen by all the approaches (Table S4) suggesting all five selection approaches may select equally the optimal models with good discriminatory power.
