  1. 1The operational taxonomic units (OTUs) were defined with 3% dissimilarity level.
  2. 2The coverage percentage (Good’s), richness estimators (ACE and Chao1) and diversity indices (Shannon and Simpson) were calculated using Good’s method [66] and the mothur program, respectively.
  3. 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.
