Mathematical model

Associations between bacterial species in the gut microbiota of “humanized” mice. A spring graph in which nodes correspond to significant relationships between “species”-level, and edges correspond to the top 300 nonlinear relationships. Node size is proportional to the number of these relationships between species relationships, black edges represent relationships explained by diet, and node glow color is proportional to the fraction of adjacent edges that are black (100% is red, 0% is blue)
