Table 1 Results from non-parametric multivariate dissimilarity tests reflect variation of microbial communities at differing depths and incubation temperatures with respect to bacterial/archaeal, fungal, and functional gene profiles

  1. Three tests were used; MRPP, multi-response permutation procedures; Adonis, permutational multivariate analysis of variance using distance matrices; and ANOSIM, analysis of similarity. Results are based on distance matrices calculated with Bray-Curtis index, but Sørenson was also used and generated similar outcomes
  2. Bold values indicate P < 0.05
  3. *** indicates P  <  0.01
