Download or read book Doing Nutrition Differently written by Allison Hayes-Conroy and published by Routledge. This book was released on 2016-05-13 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Hegemonic nutrition' is produced and proliferated by a wide variety of social institutions such as mainstream nutrition science, clinical nutrition as well as those less classically linked such as life science/agro-food companies, the media, family, education, religion and the law. The collective result is an approach to and practice of nutrition that alleges not only one single, clear-cut and consented-upon set of rules for 'healthy eating,' but also tacit criteria for determining individual fault, usually some combination of lack of education, motivation, and unwillingness to comply. Offering a collection of critical, interdisciplinary replies and responses to the matter of 'hegemonic nutrition' this book presents contributions from a wide variety of perspectives; nutrition professionals and lay people, academics and activists, adults and youth, indigenous, Chicana/o, Latina/o, Environmentalist, Feminist and more. The critical commentary collectively asks for a different, more attentive, and more holistic practice of nutrition. Most importantly, this volume demonstrates how this 'new' nutrition is actually already being performed in small ways across the American continent. In doing so, the volume empowers diverse knowledges, histories, and practices of nutrition that have been marginalized, re-casts the objectives of dietary intervention, and most broadly, attempts to revolutionize the way that nutrition is done.

Download or read book Freshwater Fisheries Ecology written by John F. Craig and published by John Wiley & Sons. This book was released on 2016-01-12 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

Download or read book Nature and Bureaucracy written by David Jenkins and published by Taylor & Francis. This book was released on 2022-09-08 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book questions how bureaucracies conceive of, and consequently interact with, nature, and suggests that our managed public landscapes are neither entirely managed nor entirely wild, and offers several warnings about bureaucracies and bureaucratic mentality. One prominent challenge facing scientists, policymakers, environmental activists, and environmentally concerned citizens, is to recognize that human influence in the natural world is pervasive and has a long history. How we act, or choose not to act, today will continue to determine the future of the natural world. Western-style management of nature, mediated by economic rationality and state bureaucracies, may not be the best strategy to maintain environmental integrity. The question is, what kinds of human influence, conceived of in the widest possible sense, will produce ideal environments for future generations? The related question is, who gets to choose? The author approaches the problem of analyzing the mutual influence of human and natural systems from two perspectives: as an objective scholar investigating bureaucracies and natural systems from the outside, and over the last decade as an inside practitioner working in various roles in federal land management agencies developing policies and regulations involved in the control of natural systems. This book will be of great interest to students and scholars of natural resource management, policy and politics, and professionals working in environmental management roles as well as policymakers involved in public policy and administration.

Available in PDF, EPUB and Kindle. Book excerpt: Virtually every area of research associated with sharks and their relatives has been strongly impacted by the revolutionary growth in technology. The questions we can now ask are very different than those reported even two decades ago. Modern immunological and genetic techniques, satellite telemetry and archival tagging, modern phylogenetic analysis, GIS, and bomb dating, are just a few of the techniques and procedures that have become a part of our investigative lexicon. A modern synthesis of the biology of Chondrichthyans, Biology of Sharks and Their Relatives, Second Edition discusses significant advances in the development and application of new molecular techniques to the understanding of the phylogenetic relationships among and between these groups. The book considers the effect of global changes on the status of sharks and their relatives, and how advances in technology and analytical techniques have changed not only how we approach problem solving and scientific investigations, but how we formulate questions. The book also introduces applications of new and novel laboratory devices, techniques, and field instruments. This second edition of the award winning and groundbreaking original exploration of the fundamental elements of the taxonomy, systematics, physiology, and ecology of sharks, skates, rays, and chimera, presents cohesive and integrated coverage of key topics and discusses technological advances used in modern shark research. Offering a well-rounded picture for students and researchers, and far above competitors in scope and research, this new volume holds a wealth of data on the current status of Chondrichthyan research and provides the basis and springboard for original research.

Download or read book Pacific Salmon Life Histories written by Cornelis Groot and published by UBC Press. This book was released on 1991 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific salmon are an important biological and economic resource of countries of the North Pacific rim. They are also a unique group of fish possessing unusually complex life histories. There are seven species of Pacific salmon, five occurring on both the North American and Asian continents (sockeye, pink, chum, chinook, and coho) and two (masu and amago) only in Asia. The life cycle of the Pacific salmon begins in the autumn when the adult female deposits eggs that are fertilized in gravel beds in rivers or lakes. The young emerge from the gravel the following spring and will either migrate immediately to salt water or spend one or more years in a river or lake before migrating. Migrations in the ocean are extensive during the feeding and growing phase, covering thousands of kilometres. After one or more years the maturing adults find their way back to their home river, returning to their ancestral breeding grounds to spawn. They die after spawning and the eggs in the gravel signify a new cycle. Upon this theme Pacific salmon have developed many variations, both between as well as within species. Pacific Salmon Life Histories provides detailed descriptions of the different life phases through which each of the seven species passes. Each chapter is written by a scientist who has spent years studying and observing a particular species of salmon. Some of the topics covered are geographic distribution, transplants, freshwater life, ocean life, development, growth, feeding, diet, migration, and spawning behaviour. The text is richly supplemented by numerous maps, illustrations, colour plates, and tables and there is a detailed general index, as well as a useful geographical index.

Download or read book Salmon Without Rivers written by Jim Lichatowich and published by . This book was released on 1999-08 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Fundamentally, the salmon's decline has been the consequence of a vision based on flawed assumptions and unchallenged myths.... We assumed we could control the biological productivity of salmon and 'improve' upon natural processes that we didn't even try to understand. We assumed we could have salmon without rivers." --from the introduction From a mountain top where an eagle carries a salmon carcass to feed its young to the distant oceanic waters of the California current and the Alaskan Gyre, salmon have penetrated the Northwest to an extent unmatched by any other animal. Since the turn of the twentieth century, the natural productivity of salmon in Oregon, Washington, California, and Idaho has declined by eighty percent. The decline of Pacific salmon to the brink of extinction is a clear sign of serious problems in the region. In Salmon Without Rivers, fisheries biologist Jim Lichatowich offers an eye-opening look at the roots and evolution of the salmon crisis in the Pacific Northwest. He describes the multitude of factors over the past century and a half that have led to the salmon's decline, and examines in depth the abject failure of restoration efforts that have focused almost exclusively on hatcheries to return salmon stocks to healthy levels without addressing the underlying causes of the decline. The book: describes the evolutionary history of the salmon along with the geologic history of the Pacific Northwest over the past 40 million years considers the indigenous cultures of the region, and the emergence of salmon-based economies that survived for thousands of years examines the rapid transformation of the region following the arrival of Europeans presents the history of efforts to protect and restore the salmon offers a critical assessment of why restoration efforts have failed Throughout, Lichatowich argues that the dominant worldview of our society -- a worldview that denies connections between humans and the natural world -- has created the conflict and controversy that characterize the recent history of salmon; unless that worldview is challenged and changed, there is little hope for recovery. Salmon Without Rivers exposes the myths that have guided recent human-salmon interactions. It clearly explains the difficult choices facing the citizens of the region, and provides unique insight into one of the most tragic chapters in our nation's environmental history.

Download or read book Travels Among the Dena written by Frederica de Laguna and published by University of Washington Press. This book was released on 2011-10-01 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This robust and engaging travel narrative re-creates a remarkable adventure in the summer of 1935, when Frederica de Laguna, then in her late 20s, led a party of three other scientists down the rivers of the middle and lower Yukon valley, making a geological and archaeological reconnaissance. De Laguna has based her story on her field notes, journals, and letters home. She augments this first-hand account with excerpts from the reports of earlier explorers and data published after her trip. The result is a fascinating and informative cross-cut of historical events along the Yukon River and its tributaries. Travels Among the Dena chronicles the expedition from its outfitting in Seattle and the trip by steamer and railway to Fairbanks and Nenana, through an 80-day journey on skiffs down the Tanana and Yukon rivers to Holy Cross near the coast, with side trips on the Koyukuk, Khotol, and Innoko rivers, before a one-day return flight to Fairbanks with pioneer bush pilot Noel Wien. Maps illustrate the route taken downriver, and the author’s photographs capture images of the time. The resulting volume is both a delightful addition to the literature of travel adventure in Alaska and an important contribution to the discipline of anthropology.

Download or read book Salmon written by Jude Isabella and published by Rocky Mountain Books Ltd. This book was released on 2014-11-14 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salmon: A Scientific Memoir investigates a narrative that is important to the identity of the Pacific Northwest Coast – the salmon as an iconic species. Traditionally it’s been a narrative that is overwhelmingly about conflict. But is that always necessarily the case? The story follows John Steinbeck’s advice: the best way to achieve reality is to combine narrative with scientific data. By following ecologists, archaeologists and fisheries biologists studying salmon, humans and their shared habitat, the reader learns about the fish through the eyes of scientists in the field. Each chapter focuses on a portion of the salmon’s journey to and from their natal streams; on one of the five Pacific salmon species most commercially important to North Americans; and on the different ways scientists study the fish. It’s also about the scientific journey of ecologists, archaeologists and fisheries biologists and how the labs gathering data today echo coastal indigenous people who have harvested salmon successfully since the end of the last ice age. Each group established a reciprocal economic system, one that revolves around community and knowledge, a system with straightforward rules, sometimes as simple as “you get what you give.”

In this compilation researched and written by the editors, journalists, and photographers of Morris Communications’ Alaskan publications, readers get a dramatic overview of the history, biology, economics, and complex forces impacting this iconic fishery, including dramatic images and stories from the Kenai River, where a world record 97.5 pounder was caught.

Download or read book Physiological Ecology of Pacific Salmon written by Cornelis Groot and published by UBC Press. This book was released on 2010-10-01 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year, countless juvenile Pacific salmon leave streams and rivers on their migration to feeding grounds in the North Pacific Ocean and the Bering Sea. After periods ranging from a few months to several years, adult salmon enter rivers along the coasts of Asia and North America to spawn and complete their life cycle. Within this general outline, various life history patterns, both among and within species, involve diverse ways of exploiting freshwater, estuarine, and marine habitats. There are seven species of Pacific salmon. Five (coho, chinook chum, pink, and sockeye) occur in both North America and Asia. Their complex life histories and spectacular migrations have long fascinated biologists and amateurs alike. Physiological Ecology of Pacific Salmon provides comprehensive reviews by leading researchers of the physiological adaptations that allow Pacific Salmon to sustain themselves in the diverse environments in which they live. It begins with an analysis of energy expenditure and continues with reviews of locomotion, growth, feeding, and nutrition. Subsequent chapters deal with osmotic adjustments enabling the passage between fresh and salt water, nitrogen excretion and regulation of acid-base balance, circulation and gas transfer, and finally, responses to stress. This thorough and authoritative volume will be a valuable reference for students and researchers of biology and fisheries science as they seek to understand the environmental requirements for the perpetuation of these unique and valuable species.
