  1. aBac: Bacteria, Arc: Archaea.
  2. bOTUs are defined at the 98% sequence similarity using 16S rRNA hypervariable V6 region.
  3. cEvenness is defined as Shannon/ln(# OTU).
  4. dRichness is defined as (# singleton OTU-1)/log10N. The maximum value is (N-1)/log10N.
  5. eGood’s coverage is defined as 1-(# singleton OTU)/N.
  6. fThe read number is rarefied to the minimum sample size of all compared samples by resampling with 1000 iterations. Data derived from all reads per sample are available in Additional file 1: Table S2.
