Figure 7

The co-occurrence network interactions of soil bacteria (a) and fungi (b). Nodes represent OTU, whereas a connection indicates a strong (r > 0.6) and significant positive (p < 0.05) correlation. The color of the nodes indicated the phylum, the size of each node was proportional to the number of connections (i.e., degree); the thickness of each connection between two nodes (i.e., edge) was proportional to the correlation coefficient (red indicates a positive correlation and gray indicates negative correlation).
