Scientist and author Cristina Eisenberg presents a fascinating and wide-ranging look at the dramatic ecological consequences of predator removal (and return) as she explores the concept of "trophic cascades" and the role of top predators in regulating ecosystems. She shows how and why animals such as wolves, sea otters, and sharks exert such a disproportionate influence on their environment, and considers how this notion can help provide practical solutions for restoring ecosystems. Trophic cascades are powerful stories about ecosystem processes-of predators and their prey, of what it takes to survive in a landscape, of the flow of nutrients. The Wolf's Tooth is the first book to focus on the vital connection between trophic cascades and biodiversity in a way that is accessible to a diverse readership.
