Widespread mesopredator effects after wolf extirpation

► We hypothesize that the release of coyotes from wolf suppression is affecting faunal communities. ► We document various cases of coyote predation on or killing of species of conservation concern. ► The apparent decline of leporids might be linked to increased coyote predation. ► We make recommendations for ecological research on wolves, coyotes, and communities. ► We suggest more studies on alternatives to the killing coyotes such as reducing food subsidies.
