Nature Reviews Microbiology, Published online: 22 September 2023; doi:10.1038/s41579-023-00969-0

In this Review, McCallum and Tropini discuss physical and biological factors that affect microbiota biogeography and organization at different scales, starting with an overview of the whole gut at the macroscale and then zooming in to the scale of host and microbial interactions.
