Figure 4. Co-occurrence network of (A) bacterial and (B) fungal communities.

Dot and triangle represent bacterial and fungal OTUs (OTUs with a relative abundance >0.01%), respectively. OTUs were colored according to major phylum (phylum with relative abundance >1%). Edges represent Spearman correlation relationships (P < 0.01). Gray lines indicate positive associations and pink lines indicate negative associations. The circles represent modules of the networks. The pie graphs in the below two panels show the composition of the modules in (C) bacterial and (D) fungal networks with the number representing the number of OTUs.
