a–c Significant Pearson correlations between prokaryotic community, viral community, and pH. d Principal component analysis (PCA) of geochemical data as derived from Euclidean dissimilarities, and principle coordinate analysis (PCoA) of e prokaryotic communities and f viral communities as derived from Bray–Curtis dissimilarities. The analysis of similarity (ANOSIM) statistics considers samples grouped by depth (inside and outside the dashed ellipses)
