A Montana State University study of Yellowstone National Park and the surrounding area shows that increased population and density, as well as a changing climate, are affecting the overall ecological health of the region: here.
More than 10 miles into the backcountry of Yellowstone National Park, on the edge of the caldera, lives a high-elevation community so diverse that Montana State University scientists call it “incredible, unique and truly weird.” The community of microorganisms lives in a sapphire blue hot spring 8,600 feet above sea level on the Continental Divide. It’s a pool where volcanic gases rise to mix with snowmelt and rainwater, a phenomenon that allows for exceptionally high levels of diversity, said Dan Colman, assistant research professor in the Department of Microbiology and Immunology in the College of Agriculture and the College of Letters and Science: here.
