Alpha diversity
Rarefied OTU richness and evenness did not differ between field (tfield) and the climate room before disturbance (t0), but there was a significant drop in both parameters upon the disturbance treatment, which was independent of the range (Figure 3A, F). For both rarefied richness and logit PIE, the models with time as a second order polynomial yielded the lowest AICc (Table S3). Richness varied with time but not between ranges. Over the first three time points (t1, t2 and t4), rarefied richness increased but decreased again at the final time point (t12). Overall, richness was higher at 22 °C and the interaction between time and temperature was also significant (Figure 3B-E) but the interaction between range and temperature was not. Similarly, logit PIE varied with time and between temperatures, with high evenness at 22 °C, but neither differed between ranges nor yielded no significant interaction terms (Figure 3G-J, see Table S2b for all statistical output).
