Summary:
Coyote and red fox fur trapping records across North America have been used by scientists to document how the presence of wolves influences the balance of smaller predators further down the food chain. 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.
