Microbial co-occurrence networks, modularity, and keystone taxa. A Co-occurrence networks of 986 MAGs in the CON and AOS groups (n = 16). Different colors of nodes indicate different genera. The node size is weighted based on node degree. The red and blue links represent positive and negative correlations, respectively. Highly connected modules within (Ba) CON and (Bc) AOS networks (n = 16). Classification of nodes to identify putative keystone taxa within (Bb) CON and (Bd) AOS networks (n = 16)
