Model setting
The most common model setting or regularization multiplier and feature class (RM-FC) combinations for fish was 5xH (Figure 2a, Table S3), while for odonates it was 5xL (Figure 2b, Table S3). Further, greater number of optimal models had RM-FC combinations of larger RM values and more complex feature classes (Figure 2a-b, Table S3). For three fish and four odonates all the five selection approaches selected same optimal models (Table 1). Whereas, ORTEST_PER agreed best with EXP for fish and AUCDIFF_PER and ORTEST_BALfor the odonates (Table 1; Table S3).
