Figure 4

Redundancy analysis showing all macroinvertebrate metrics constrained by stream physical-chemical characteristics across the 23 study sites. Both axes were found to be statistically significant following a permutation ANOVA test (p = 0.001 and p = 0.033, for RDA1 and RDA2 respectively). Meta stands for DNA metabarcoding, Morph for morphological, DO for dissolved oxygen, and DOC for dissolved organic carbon.
