Recovering predators link aquatic and terrestrial ecosystems: River otters subsidize coyotes with carrion.

Despite global declines in the abundance and distribution of predators, conservation and reintroduction efforts are increasingly leading to predator recoveries. Unexpected species interactions and ecological consequences often arise when these predator recoveries occur. Here, we describe a novel species interaction in which coyotes () kleptoparasitize North American river otters () in a region of river otter recovery along the north-central California coast, USA.
