From the Wildlife Society:
When wolves prey on beavers in and around Voyageurs National Park, cascading effects ripple throughout the whole ecosystem.
Researchers have been documenting wolves going after the aquatic rodents, but they didn’t know much about some of the dynamics—factors that could have implications for the environment, since beavers are ecosystem engineers.
“We’ve been really trying to understand beaver interactions on a more broad scale,” said Thomas Gable, project lead of the Voyageurs Wolf Project. “And then, how do those interactions influence larger ecological processes?”
