¹The operational taxonomic units (OTUs) were defined with 3% dissimilarity level.
²The coverage percentage (Good), richness estimators (ACE and Chao1) and
diversity indices (Shannon and Simpson) were calculated using Good's method.
(Good, 1953) and the MOTHUR program.
³The Shannon index of evenness was calculated with the formula E = H/ln(S),
where H is the Shannon diversity index and S is the total number of sequences
in that group.
