Animal Trapping Records Reveal Strong Wolf Effect Across North America

As coyotes have expanded in North America, they have become a major cause of concern for the livestock industry.

From Alaska and Yukon to Nova Scotia and Maine, the researchers have demonstrated that a “wolf effect” exists, favoring red foxes where wolves are present and coyotes where wolves are absent.
