In this documentary, biologist Aaron Wirsing explored why wolves and other top predators （捕食者）were needed for diverse ecosystems to develop. Using a simple video camera, Wirsing is gaining a unique view point on predatorprey relationships and changing the way we think about wolves. Yellowstone has benefited from the reintroduction of wolves in ways that we did not anticipate, especially the plexity of biological interactions（互動） in the park, explained Mark Boyce, a professor in the Department of Biological Sciences.
