Description of the data: Heat maps reflecting the relative abundances of the 10 most abundant phyla (A), the 25 most abundant orders (B) and the 50 most abundant genera, aggregated by time (tf, t0, t1, t2, t4 and t12) and temperature (15 °C and 22 °C).The number of OTUs in each taxon is indicated between brackets behind the taxon classification.

Description of the data: OTU-level analysis. (A) Model coefficients and 95% confidence intervals of the 10 most abundant OTUs significantly associated to 15 °C (blue) and the 5 most abundant OTUs significantly associated to 22 °C (red) calculated from the model comparing temperatures over the time points t1, t2, t4 and t12. (B) Model coefficients and 95% confidence intervals of the 10 most abundant OTUs associated with native and the 10 most abundant OTUs associated with non-native populations over the time points t1, t2, t4 and t12. (C) Spearman’s rank correlation coefficients and 95% confidence intervals of the 10 most abundant OTUs positively associated with relative growth rate (RGR) and the 10 most abundant OTUs negatively associated with RGR. (D) Spearman’s rank correlation coefficients and 95% confidence intervals OTUs positively associated with the thallus brittleness disease symptom and OTUs negatively associated with thallus brittleness. OTUs are labeled with genus classification and the OTU number in subscript. OTUs from the global field study (Bonthond et al., 2020) are labeled with an ‘R’, whereas OTUs without this label were only identified in the current study. OTUs that were identified as core OTUs in the same study are labeled with red, green or blue (endophyte, epiphyte or water, respectively) The confidence intervals of model derived coefficients (A, B) were calculated by multiplying the standard error with 1.96 which was summed with and subtracting from the mean. For Pearson correlation rank coefficients, confidence intervals were obtained by bootstrapping the data 1000 times.
