  1. Associations were calculated with the Dufrene–Legendre indicator species analysis routine (Indval, indicator value) in R. Data table shows results for the analysis where rare OTUs (<1% relative abundance) were excluded. Significance levels: *P ≤ 0.05; **P ≤ 0.01. P values were corrected for multiple comparisons using the false discovery rate (FDR) with the Benjamini–Hochberg method. Full results of indicator species analysis are presented in Additional file 6
