Fig. 2 Redundancy analysis <strong>of</strong> metrics and environmental parameters (mountain <strong>streams</strong>). All four subfigures are related to the same<br />
analysis but only those metrics calculated <strong>with</strong> a certain organism group are displayed in each subfigure. Gradients: gen1 ¼ 1st PCA<br />
axis general degradation; gen2 ¼ 2nd PCA axis general degradation; hydro ¼ 1st PCA axis hydromorphological degradation (reach<br />
scale); land use ¼ land use index; microh1 ¼ 1st PCA axis hydromorphological degradation (microhabitat scale); microh2 ¼ 2nd PCA<br />
axis hydromorphological degradation (microhabitat scale); poll1 ¼ 1st PCA axis eutrophication/organic pollution; poll2 ¼ 2nd PCA<br />
axis eutrophication/organic pollution (compare Table 10). (a) diatom metrics; (b) <strong>macrophytes</strong> metrics; (c) invertebrate metrics; (d)<br />
fish metrics.<br />
