"The fact that these populations have distinct diets is valuable, because it allows us to understand the role that the gut microbiome plays in helping bears extract nutrition from very different food sources," says Sarah Trujillo, corresponding author of the study and a former graduate student at Northern Michigan University .
"And because the parks are protected, well-conserved environments, this study can serve as a baseline for future research," says Diana Lafferty, co-author of the study and an assistant professor of biology at NMU."For example, researchers will be able to compare the gut microbiomes of bears in more disturbed systems—such as areas where bears have more access to garbage and human foods—to the data from this study.
