Module membership identification using dynamic tree. (A) Bacterial taxa dendrogram and module colors, (B) Clustering of module eigenvalues. In the dendrogram of panel A, each leaf, shown as a short vertical line, corresponds to a bacterial taxon. Branches of the dendrogram grouped together densely and interconnected represent highly co-occurring bacterial taxa. The highly co-occurred bacterial taxa can be classified into 18 different modules (from pink to green modules). In the clustering dendrogram of module membership, with dissimilarity based on the topological overlap, the pink, yellow, and brown modules show higher similarity to each other compared to the other modules. The gray module indicates unassigned bacterial taxa.
