Island Press The Wolf's Tooth: Keystone Predators, Trophic Cascades, and Biodiversity
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 ecosystem health and functioning. Eisenberg examines both general concepts and specific issues, sharing accounts from her own fieldwork to illustrate and bring to life the ideas she presents. She considers how resource managers can use knowledge about trophic cascades to guide recovery efforts, including how this science can be applied to move forward the bold vision of rewilding the North American continent. In the end, the author provides her own recommendations for local and landscape-scale applications of what has been learned about interactive food webs. At their most fundamental level, 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 restoring biodiversity and habitats, and to do so in a way that is accessible to a diverse readership.

Island Press The Carnivore Way: Coexisting with and Conserving North America's Predators
What would it be like to live in a world with no predators roaming our landscapes? Would their elimination, which humans have sought with ever greater urgency in recent times, bring about a pastoral, peaceful human civilization? Or in fact is their existence critical to our own, and do we need to be doing more to assure their health and the health of the landscapes they need to thrive? In The Carnivore Way, Cristina Eisenberg argues compellingly for the necessity of top predators in. large, undisturbed landscapes, and how a continental-Iong corridor - a "carnivore way" - provides the room they need to roam and connected landscapes that allow them to disperse. Eisenberg follows the footsteps of six large carnivores - wolves, grizzly bears, lynx, jaguars, wolverines, and cougars - on a 7,500-mile wildlife corridor from Alaska to Mexico along the Rocky Mountains. Backed by robust science, she shows how their well-being is a critical factor in sustaining healthy landscapes and how it is possible for humans and large carnivores to coexist peacefully and even to thrive. University students in natural resource science programs, resource managers, conservation organisations, and anyone curious about carnivore ecology and management in a changing world will find a thoughtful guide to large carnivore conservation that dispels long-held myths about their ecology and contributions to healthy, resilient landscapes.
