OTU97 table main ms filteredOTU97_84samples

A: OTU table showing the 2099 OTUs after rarefaction and removing ‘water’ contaminants (see Methods and Results) identified in the MiSeq analysis of the 84 samples that were amplified with standard PCR, analyzed by clustering 97% identical sequences in Mothur. As before, the table was rarefied at 8900 reads. only The 18 abundant OTUs according to our criterion of ≥10% prevalence in at least two samples, are highlighted with Bold print. B: The same OTU table before rarefaction. To facilitate reading and interpretation we have named the 98 OTUs of highest overall abundance (Fig. S3) using five letters that refer to their bacterial order followed by a specific number that identifies their overall prevalence rank. Six of them had previously been identified in the guts of three species of Acromyrmex leaf-cutting ants from the same sampling site, and retained their names from that study (ActAcro1, EntAcro1, EntAcro2, EntAcro10, RhiAcro1 and WolAcro1: Sapountzis et al. 2015).
