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.

This book is a product of the joint JGOFS (Joint Global Ocean Flux Study)/LOICZ (Land–Ocean Interactions in the Coastal Zone) Continental Margins Task Team which was established to facilitate continental margins research in the two projects. It contains signi cant information on the physical, biogeochemical, and ecosystems of continental margins nationally and regionally and provides a very valuable synthesis of this information and the physical, biogeochemical and ecosystem processes which occur on continental margins. The publication of this book is timely as it provides a very strong foundation for the development of the joint IMBER (Integrated Marine Biogeochemistry and Ecosystems Research)/LOICZ Science Plan and Implemen- tion Strategy for biogeochemical and ecosystems research in the continental margins and the impacts of global change on these systems. This initiative will move forward integrated biogeochemical and ecosystems research in the continental margins. We thank all the contributors to this volume and especially Kon-Kee Liu who has dedicated a great deal of time to ensuring a high-quality book is published. IMBER Scienti c Steering Committee Julie Hall LOICZ Scienti c Steering Committee Jozef Pacyna v 1 Preface In general, interfaces between the Earth’s larger material reservoirs (i. e. , the land, atmosphere, ocean, and sediments) are important in the control of the biogeoche- cal dynamics and cycling of the major bio-essential elements, including carbon (C), nitrogen (N), phosphorus (P), sulfur (S), and silicon (Si), found in organic matter and the inorganic skeletons, shells, and tests of benthic and marine organisms.
