Chloroperlidae, Lepidostomatidae and Gammaridae were excluded because stranding propensity was not computable in one or more of the three reaches; also for the stranding CCA (Figure 5b).
Table 3. Simper statistic showing the taxa that most contributed to dissimilarity among RF and HP reaches of the three rivers. Taxa that cumulatively contribute (cum sum) to ca. 90 % of the differences between each pair of groups (RF vs HP) are shown.
