OTU co-occurrence network and module-trait associations. a OTU co-occurrence network where OTU (nodes) are colored according to the phyla to which they belong. Blue edges correspond to positive correlations and red edges to negative correlations. Any resulting correlations with p value ≥0.01 and abs(r) <0.3 were removed. b OTU co-occurrence network were OTU (nodes) are colored according to WGCNA module colors. c Module–trait associations are shown. Each cell of the matrix contains the correlation between one OTU module and a metabolic trait, and the corresponding p value. The table is color-coded by correlation according to the color legend (red for positive correlations and green for negative correlations).
