Diversity and compositional changes in the gut microbiota of wild and captive vertebrates: a meta-analysis

Abstract The gut microbiota is recognised as an essential asset for the normal functioning of animal biology. When wild animals are moved into captivity, the modified environmental pressures are expected to rewire the gut microbiota, yet whether this transition follows similar patterns across verteb...
