William Ripple is the author of more than 100 peer-reviewed scientific articles, most of which deal with trophic cascades. [10]Ripple, along with his frequent coauthor, Robert Beschta, have studied, published, and publicized the positive impact that gray wolves have had on the Yellowstone National Park ecosystem since their reintroduction in 1995 and 1996.
