Carnivore Gut Microbes Offer Insight Into Health of Wild Ecosystems

A new study finds the microbial ecosystem in the guts of wild marten (Martes americana) that live in relatively pristine natural habitat is distinct from the gut microbiome of wild marten that live in areas that are more heavily impacted by human activity.

A new study finds the microbial ecosystem in the guts of wild marten (Martes americana) that live in relatively pristine natural habitat is distinct from the gut microbiome of wild marten that live in areas that are more heavily impacted by human activity. The finding highlights an emerging tool that will allow researchers and wildlife managers to assess the health of wild ecosystems.

“Specifically, we found that wild marten in relatively undisturbed environments have more carnivorous diets than martens in human-affected areas,” says Erin McKenney, co-lead author of a paper on the work and an assistant professor of applied ecology at North Carolina State University. Marten are small mammals, related to weasels, ferrets and mink.

“In conjunction with our other work on carnivore microbiomes, this finding tells us the microbial ecosystems in carnivore guts can vary significantly, reflecting a carnivore’s environment,” McKenney says. “Among other things, this means we can tell how much humans are impacting an area by assessing the gut microbiomes of carnivores that live in that area – which can be done by testing wild animal feces. In practical terms, this work is revealing a valuable tool for assessing the health of wild ecosystems.”
