Coabundance networks of Methanomassiliicoccus (green node, dark edges) and “Ca. Methanomethylophilus” (orange node, light edges) in the human gut largely overlap. Both Methanomassiliicoccales genera are significantly coabundant (cyan edge). Their abundances are also coordinated with those of another archaeon (blue node) and TMA-producing bacterial taxa (red nodes).
