  1. Variation in prokaryotic and fungal community structures explained by environmental variables and geographical distance alone as well as shared variation.
  2. Constrained ordinations were calculated based on Bray-Curtis dissimilarities of relative abundances (n = 70). P-values indicate significance of environmental variables after controlling for geographical distance and vice versa, assessed by PERMANOVA with 9999 permutations.
