  1. 1To estimate these α- and β-diversity indices, the number of bacterial and archaeal sequences per sample were normalized to 2000 and 500, respectively. α-diversity indices were calculated at the genus level for bacterial communities and at the species level for archaeal communities. Principal Coordinates Analysis (PCoA) was conducted using Bray-Curtis dissimilarity matrices
  2. 2Abundance from qPCR and relative abundance were both log10-transformed before we calculated these ratios
