From: Microbial community composition along the digestive tract in forage- and grain-fed bison
Microbial diversity along the length of the bison digestive tract. Letters above the chart indicate results of Tukey’s HSD test; sections marked with different letters were significantly different from one another. a Diversity of the gut microbiota in forage-finished bison, as measured by the Shannon index. b Diversity of the gut microbiota in grain-finished bison, as measured by the Shannon index
