Richness, diversity and coverage of bacterial 16S rRNA and Archeal <i>mcrA</i> clone libraries.

Notes — n is number of clones in each library, N in number of Operational Taxonomic Unit (OTU) is based on 97% nucleotide identity. Richness and diversity are shown as: Chao1 (richness estimate), ACE (abundance-based coverage estimator), Shannon diversity index and the inverse of Simpson diversity index; 95% confidence intervals are indicated in brackets. Coverage is calculated in MOTHUR using methods described by Good (1953).
