Fig. 4. Mantel test showing correlations among different microbial components.
Scatterplots of each pair of beta-diversity (i.e., Bray–Curtis similarity) are shown on the left part of the figure. The results of each Mantel test are shown on the right. The distribution of beta-diversity of each component is shown on the diagonal. The results show that free-living and particle-associated prokaryotic communities were correlated most closely (r = 0.880), followed by chloroplasts and attached & large prokaryotes (r = 0.643). Viruses were much better correlated to prokaryotes than eukaryotes (rightmost column). The statistical significance of each component was evaluated by a permutation test with 9999 permutations, and the P-value of all tests is 0.0001. Source data are provided as a Source data file.
