Download or read book The Fats of Life written by Caroline M. Pond and published by Cambridge University Press. This book was released on 1998-08-13 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to fill the gap between unscientific comments about the hazards and benefits of high-fat or low-fat diets and weight control found in magazines and technical and medical reports about lipid biochemistry and obesity. It aims to explain in simple language the biology of feeding and fasting, fattening and slimming in wild animals as well as people. Topics include where fat comes from and how animals and plants handle them, their natural roles in migration, mating breeding and living in unpredictable habitats such as deserts and arctic regions, and their contributions to our cookery, paints and medicines. The physiological mechanisms of digesting, transporting and utilising energy stores are discussed, along with the contribution of fatty tissue to body insulation and the protection of delicate organs. Archaeological, anthropological and physiological evidence is assembled to explore how, when and why people have become fat, and how evolutionary forces have determined the modern diversity of body shape and size. The book ends with a brief account of the contribution of dietary fats and obesity to health in the modern world.
Download or read book Foraging Theory written by David W. Stephens and published by Princeton University Press. This book was released on 2019-12-31 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: This account of the current state of foraging theory is also a valuable description of the use of optimality theory in behavioral ecology in general. Organizing and introducing the main research themes in economic analyses of animal feeding behavior, the authors analyze the empirical evidence bearing on foraging models and answer criticisms of optimality modeling. They explain the rationale for applying optimality models to the strategies and mechanics of foraging and present the basic "average-rate maximizing" models and their extensions. The work discusses new directions in foraging research: incorporating incomplete information and risk-sensitive behavior in foraging models; analyzing trade-offs, such as nutrient requirements and the threat of being eaten while foraging; formulating dynamic models; and building constrained optimization models that assume that foragers can use only simple "rules of thumb." As an analysis of these and earlier research developments and as a contribution to debates about the role of theory in evolutionary biology. Foraging Theory will appeal to a wide range of readers, from students to research professionals, in behavioral ecology, population and community ecology, animal behavior, and animal psychology, and especially to those planning empirical tests of foraging models.

Download or read book Noninvasive Survey Methods for Carnivores written by Robert A. Long and published by Island Press. This book was released on 2012-09-26 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: The status of many carnivore populations is of growing concern to scientists and conservationists, making the need for data pertaining to carnivore distribution, abundance, and habitat use ever more pressing. Recent developments in “noninvasive” research techniques—those that minimize disturbance to the animal being studied—have resulted in a greatly expanded toolbox for the wildlife practitioner. Presented in a straightforward and readable style, Noninvasive Survey Methods for Carnivores is a comprehensive guide for wildlife researchers who seek to conduct carnivore surveys using the most up-to-date scientific approaches. Twenty-five experts from throughout North America discuss strategies for implementing surveys across a broad range of habitats, providing input on survey design, sample collection, DNA and endocrine analyses, and data analysis. Photographs from the field, line drawings, and detailed case studies further illustrate on-the-ground application of the survey methods discussed. Coupled with cutting-edge laboratory and statistical techniques, which are also described in the book, noninvasive survey methods are effi cient and effective tools for sampling carnivore populations. Noninvasive Survey Methods for Carnivores allows practitioners to carefully evaluate a diversity of detection methods and to develop protocols specific to their survey objectives, study area, and species of interest. It is an essential resource for anyone interested in the study of carnivores, from scientists engaged in primary research to agencies or organizations requiring carnivore detection data to develop management or conservation plans.

This book was released on 2007-11-19 with total page 1296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the bestselling second edition, mounting research into fatty acids reveals new and more defined links between the consumption of dietary fats and their biological health effects. Whether consuming omega-3 to prevent heart disease or avoiding trans fats to preserve heart health, it is more and more clear that not only the quantity but the type of fatty acid plays an important role in the etiology of the most common degenerative diseases. Keeping abreast of the mechanisms by which fatty acids exert their biological effects is crucial to unraveling the pathogenesis of a number of debilitating chronic disorders and can contribute to the development of effective preventive measures. Thoroughly revised to reflect the most resent research findings, Fatty Acids in Foods and their Health Implications, Third Edition retains the highly detailed, authoritative quality of the previous editions to present the current knowledge of fatty acids in food and food products and reveal diverse health implications. This edition includes eight entirely new chapters covering fatty acids in fermented foods, the effects of heating and frying on oils, the significance of dietary ?-linolenate in biological systems and inflammation, biological effects of conjugated linoleic acid and alpha-linolenic acid, and the role of fatty acids in food intake and energy homeostasis, as well as cognition, behavior, brain development, and mood disease. Several chapters underwent complete rewrites in light of new research on fatty acids in meat, meat products, and milk fat; fatty acid metabolism; eicosanoids; fatty acids and aging; and fatty acids and visual dysfunction. The most complete resource available on fatty acids and their biological effects, Fatty Acids in Foods and their Health Implications, Third Edition provides state-of-the-science information from all corners of nutritional and biomedical research.

This book will be of interest to researchers and resource managers working with aquatic ecosystems.
Download or read book Environmental Consequences of the Chernobyl Accident and Their Remediation written by International Atomic Energy Agency and published by IAEA. This book was released on 2006 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The explosion on 26 April 1986 at the Chernobyl nuclear power plant and the consequent reactor fire resulted in an unprecedented release of radioactive material from a nuclear reactor and adverse consequences for the public and the environment. Although the accident occurred nearly two decades ago, controversy still surrounds the real impact of the disaster. Therefore the IAEA, in cooperation with other UN bodies, the World Bank, as well as the competent authorities of Belarus, the Russian Federation and Ukraine, established the Chernobyl Forum in 2003. The mission of the Forum was to generate 'authoritative consensual statements' on the environmental consequences and health effects attributable to radiation exposure arising from the accident as well as to provide advice on environmental remediation and special health care programmes, and to suggest areas in which further research is required. This report presents the findings and recommendations of the Chernobyl Forum concerning the environmental effects of the Chernobyl accident.
