Associations were calculated using species indicator analyses (Indicator value) in R. Data table shows the results for the analysis where rare operational taxonomic units (OTUs) (<1% relative abundance) were excluded. Significance levels: ^∗p ≤ 0.05; ^∗∗p ≤ 0.01. Full results of the indicator species analysis are presented in Supplementary Table S11.
