Gut Microecology of Four Sympatric Desert Rodents Varies by Diet

Ecology and Evolution, Volume 15, Issue 3, March 2025.
We observed significant differences in the gut microbial composition of four species of rodents living in the same habitat but each consuming different diets. These differences in gut microbiota may arise as adaptations to their distinct diets and digestive needs, thereby enhancing their ability to live within the same ecosystem.
