Fig. 1

Changes in (a) mean annual air temperature [°C], (b) CTI [°C], (c) Saprobic Index [SI], (d) Multimetric Index [MMI], (e) BMWP Score, (f) Number of Taxa, (g) percentage of EPT-taxa [EPT %] during the study period 2000–2014. Plots are of type “conditional”; thus, all covariates were held constant to their median values. (h) Slopes (± 95% CI) of the relationships between response variables (a–g) and time. All slopes were significantly different from zero (p < 0.05). The slopes of MMI, BMWP Score, Number of Taxa and EPT % were inverted (they were strictly positive) because here we want to compare the rate of change, independent from the direction of change.
