In this episode, host Steve Backshall examines how the reintroduction of the wolf at Yellowstone has set off a cascade of events that have reverberated through the food chain. The beaver population has increased, while the number of coyotes have sharply declined. The pronghorn antelope, one of North America's most endangered species, has also reaped the benefits of the reappearance of the wolf. Part of the "Nature's Mircroworld" series.
