OTU97 table main ms filteredOTU97

A: OTU table showing the 2099 OTUs identified in the MiSeq analysis of 107 samples analyzed by clustering 97% identical sequences in Mothur. The table was rarefied at 8900 reads. To remove any potential water contaminants, we identified the OTUs (97% clustering) present in the blank ‘water’ samples that were sequenced along with the real samples, and removed these OTUs as contaminants if their relative abundances produced an average blank/sample ratio ≥ 0.2. B: The same OTU table presenting only the 21 abundant OTUs (Fig. S2).
