Long-term high-resolution data on social relationships, space use and microhabitat in a wild population of mice (Apodemus sylvaticus), accompanied by sampling of the gut microbiota, show that distinct sets of microorganisms dominate social and environmental transmission routes of microbiota. Microorganisms with low oxygen tolerance are more reliant on social transmission.
