Stanford research shows muskrats are a bellwether for a drying delta

The muskrat, a stocky brown rodent the size of a Chihuahua - with a tail like a mouse, teeth like a beaver and an exceptional ability to bounce back from rapid die-offs - has lived for thousands of years in one of Earth's largest freshwater deltas, in northeastern Alberta, Canada.

Today, this delta lies within one of the largest swaths of protected land in North America: a national park five times the size of Yellowstone that's home to the planet's biggest herd of free-roaming bison and the last natural nesting ground for the endangered whooping crane. It's also central to the culture and livelihoods of Indigenous peoples, including the Mikisew Cree First Nation, Athabasca Chipewyan First Nation and Métis Local 125.
