Table 1 The p-values of the differences between environmental conditions corresponding to each nitrate~ mode (low-typical, low-high, typical-high) are calculated by the Bonferroni corrected two-sample t-test with unequal variances, where “n.s.” indicates a non-significant result.

  1. Only the variables with significant p-values and visual agreement using the class-wise Pareto Density Estimation are presented. Groundwater depth on the hillslope (GW25~) and water temperature at the upper gauge (Wt18~) are thus not presented.
