  1. a Only reads that were observed five or more times were included in the analyses.
  2. b Sequences were clustered into Operational Taxonomic Units (OTUs) at 3%, 6% or 10% genetic difference.
  3. c Higher taxa refers to genus or to a more inclusive taxon (family, order, class) when sequence could not be confidently classified to the genus level.
