Fig. 4: Microbial co-occurrence network.
From: Saliva-derived microcosm biofilms grown on different oral surfaces in vitro
Microbial interactions were inferred with SPIEC-EASI algorithm using “MB” neighborhood selection procedure. Each node represents an OTU. The green edges represent positive correlation between taxa and the red ones represent negative correlation. The diameter of the node corresponds to the relative abundance of the OTU. Clusters in the network were identified using the Girvan-Newman clustering algorithm. The nodes in one cluster are labeled in the same color. The number in the name of each node represents its OTU number.
