Fig. 6

Network analysis over 20-year time series of metagenomes suggests stable connections between eukaryotes and bacteria. Circles correspond to significant, strong correlations between taxa listed on the x- and y-axes and are both colored and sized according to the correlation coefficient. Only correlations with a significant Benjamini-Hochberg-corrected p-value and a correlation coefficient of greater than or equal to 0.50 are included visually. The color corresponds to whether the x-axis partner is bacterial or eukaryotic, and shading indicates specific phylum. Self-correlations are excluded when the small subunit rRNA gene sequences were the same
