1
Sobs are operational taxonomic units (OTUs) observed at maximum sequencing effort and defined at 3% dissimilarity.
2
This column represents the percentage of observed OTUs, based on total observed OTUs, if sampling efforts were stopped at 98% Good–Turing's coverage.
3
Coverage of richness, calculated as the percentage Sobs from those predicted by catchall.
