The African Water Resource Database (AWRD) is a set of data and custom-designed tools, combined in a geographic information system (GIS) analytical framework, aimed at facilitating responsible inland aquatic resource management with a focus on inland fisheries and aquaculture. It thus provides a valuable instrument to promote food security. The AWRD data archive includes an extensive collection of datasets covering the African continent, including: surface waterbodies, watersheds, aquatic species, rivers, political boundaries, population density, soils, satellite imagery and many other physiographic and climatological data. This technical paper is the second of two publications about the AWRD, and it includes a technical manual for spatial analysts and a workbook for university students and teachers. The first part of this technical paper is available separately (ISBN 9789251057407).

Food webs hold a central place in ecology. They describe which organisms feed on which others in natural habitats. This book describes recently discovered empirical regularities in real food webs: it proposes a novel theory unifying many of these regularities, as well as extensive empirical data. After a general introduction, reviewing the empirical and theoretical discoveries about food webs, the second portion of the book shows that community food webs obey several striking phenomenological regularities. Some of these unify, regardless of habitat. Others differentiate, showing that habitat significantly influences structure. The third portion of the book presents a theoretical analysis of some of the unifying empirical regularities. The fourth portion of the book presents 13 community food webs. Collected from scattered sources and carefully edited, they are the empirical basis for the results in the volume. The largest available set of data on community food webs provides a valuable foundation for future studies of community food webs. The book is intended for graduate students, teachers and researchers primarily in ecology. The theoretical portions of the book provide materials useful to teachers of applied combinatorics, in particular, random graphs. Researchers in random graphs will find here unsolved mathematical problems.

I was asked to introduce this volume by examining "why a knowledge of ecosys tem functioning can contribute to understanding species activities, dynamics, and assemblages." I have found it surprisingly difficult to address this topic. On the one hand, the answer is very simple and general: because all species live in ecosystems, they are part of and dependent on ecosystem processes. It is impossible to understand the abundance and distribution of populations and the species diversity and composition of communities without a knowledge of their abiotic and biotic environments and of the fluxes of energy and mat ter through the ecosystems of which they are a part. But everyone knows this. It is what ecology is all about (e.g., Likens, 1992). It is why the discipline has retained its integrity and thrived, despite a sometimes distressing degree of bickering and chauvinism among its various subdisciplines: physiological, be havioral, population, community, and ecosystem ecology.

THE NEW YORK TIMES BESTSELLING DIET PHENOMENON If you’ve ever suspected that not everyone should eat the same thing or do the same exercise, you’re right. In fact, what foods we absorb well and how our bodies handle stress differ with each blood type. Your blood type reflects your internal chemistry. It is the key that unlocks the mysteries of disease, longevity, fitness, and emotional strength. It determines your susceptibility to illness, the foods you should eat, and ways to avoid the most troubling health problems. Based on decades of research and practical application, Eat Right 4 Your Type offers an individualized diet-and-health plan that is right for you. In this revised and updated edition of Eat Right 4 Your Type, you will learn: • Which foods, spices, teas, and condiments will help maintain your optimal health and ideal weight • Which vitamins and supplements to emphasize or avoid • Which medications function best in your system • Whether your stress goes to your muscles or to your nervous system • Whether your stress is relieved better through aerobics or meditation • Whether you should walk, swim, or play tennis or golf as your mode of exercise • How knowing your blood type can help you avoid many common viruses and infections • How knowing your blood type can help you fight back against life-threatening diseases • How to slow down the aging process by avoiding factors that cause rapid cell deterioration INCLUDES A 10-DAY JUMP-START PLAN

Missing Links: Evolutionary Concepts and Transitions Through Time provides readers with a compendium of scientific evidence of extinct organisms, or missing links, that bridge the evolutionary gaps between primordial species and modern life. The book introduces newcomers to the field of evolutionary science with an accessible discussion of basic scientific practices, rock and fossil dating techniques, and schools of classification. Readers are then ushered through a fascinating array of examples of evolutionary transition at all chronological and geographical scales, from the ultimate origins of life on Earth to the morphological changes that readers will observe during their lifetimes.
