Includes entries for maps and atlases.

Community ecology has undergone a transformation in recent years, from a discipline largely focused on processes occurring within a local area to a discipline encompassing a much richer domain of study, including the linkages between communities separated in space (metacommunity dynamics), niche and neutral theory, the interplay between ecology and evolution (eco-evolutionary dynamics), and the influence of historical and regional processes in shaping patterns of biodiversity. To fully understand these new developments, however, students continue to need a strong foundation in the study of species interactions and how these interactions are assembled into food webs and other ecological networks. This new edition fulfils the book's original aims, both as a much-needed up-to-date and accessible introduction to modern community ecology, and in identifying the important questions that are yet to be answered. This research-driven textbook introduces state-of-the-art community ecology to a new generation of students, adopting reasoned and balanced perspectives on as-yet-unresolved issues. Community Ecology is suitable for advanced undergraduates, graduate students, and researchers seeking a broad, up-to-date coverage of ecological concepts at the community level.

The world's leading resource on biointensive, sustainable, high-yield organic gardening is thoroughly updated throughout, with new sections on using 12 percent less water and increasing compost power. Long before it was a trend, How to Grow More Vegetables brought backyard ecosystems to life for the home gardener by demonstrating sustainable growing methods for spectacular organic produce on a small but intensive scale. How to Grow More Vegetables has become the go-to reference for food growers at every level, whether home gardeners dedicated to nurturing backyard edibles with minimal water in maximum harmony with nature's cycles, or a small-scale commercial producer interested in optimizing soil fertility and increasing plant productivity. In the ninth edition, author John Jeavons has revised and updated each chapter, including new sections on using less water and increasing compost power.

Management of benign anorectal disorders is challenging for the treating surgeons as the patients are highly distressed, the symptoms are always alarming, and surgical intervention may be associated with lifelong disabilities such as loss of sphincter control. Written by highly experienced colorectal surgeons, this book provides detailed notes on optimal management of these disorders including pre- and post-operative management. Chapters cover the entire range of benign disorders such as hemorrhoids, fissure, fistula-in-ano, anorectal injuries, anal incontinence, rectal prolapse, pelvic floor disorders, benign tumors and ulcers, and strictures. Chapters on surgical anatomy and physiology equip the surgeons with the information necessary to understand the complex anatomy and functioning of this region which makes surgery all the more difficult. Benign Anorectal Disorders is an essential reading for colorectal surgeons, general surgeons, fellows-in-training and the post-graduate students.

Despite acknowledgment that loss of living diversity is an international biological crisis, the ecological causes and consequences of extinction have not yet been widely addressed. In honor of Edward O. Wilson, winner of the 1993 International Prize for Biology, an international group of distinguished biologists bring ecological, evolutionary, and management perspectives to the issue of biodiversity. The roles of ecosystem processes, community structure and population dynamics are considered in this book. The goal, as Wilson writes in his introduction, is "to assemble concepts that unite the disciplines of systematics and ecology, and in so doing to create a sound scientific basis for the future management of biodiversity."

The warming of the Earth has been the subject of intense debate and concern for many scientists, policy-makers, and citizens for at least the past decade. Climate Change Science: An Analysis of Some Key Questions, a new report by a committee of the National Research Council, characterizes the global warming trend over the last 100 years, and examines what may be in store for the 21st century and the extent to which warming may be attributable to human activity.
