Microbial associations and spatial proximity predict North American moose ( Alces alces ) gastrointestinal community composition
Abstract Microbial communities are increasingly recognized as crucial for animal health. However, our understanding of how microbial communities are structured across wildlife populations is poor. Mechanisms such as interspecific associations are important in structuring free‐living communities, but...
