From: Gut microbiome reflect adaptation of earthworms to cave and surface environments
Co-occurrence networks of bacterial communities in the gut of earthworms (A) and soil (B) present in caves and the surface. Connections represent strong (R2 ≥ 0.7) and significant (P ≤ 0.01) correlations inferred by SparCC. The size of each node is proportional to the betweenness. Blue lines represent significant negative and red lines significant positive correlations. Node colors represent the OTU phyla
