Boxplots showing the distributions of catchment characteristics for erratic versus persistent streamflow regimes (panels A, C, G, I, K), and for the four empirically classified streamflow regime types (panels B, D, F, H, J, L). Each box represents the interquartile range (IQR), with the median represented by the horizontal line. Whiskers represent 1.5 times the IQR from the nearest quartile, while statistical outliers are shown as black dots. Plus signs (+) indicate statistically significant differences between erratic and persistent regimes according to the Kolmogorov–Smirnov test. Asterisks (*) indicate that at least one empirically classified flow regime type is statistically different from the others according to the Kruskal–Wallis test. Numbers in brackets refer to the pairs of flow regime types deemed statistically different according to pairwise Dunn’s tests.
