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).
