Microbial co-exclusion patterns reflect oxygen use and carbon source. Network graphs presenting species as nodes and co-exclusion between species as edges, where darker lines indicate stronger co-exclusions. Nodes are colored based on oxygen tolerance (left) and carbon source (right). Identical networks with labels indicating the bacterial species are presented in Additional file 1: Figure S10A,B. Historic calculus has more co-exclusions between species with different oxygen tolerance and carbon source than does plaque or modern calculus
