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 Ecology of Atlantic Salmon and Brown Trout written by Bror Jonsson and published by Springer Science & Business Media. This book was released on 2011-05-03 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Destruction of habitat is the major cause for loss of biodiversity including variation in life history and habitat ecology. Each species and population adapts to its environment, adaptations visible in morphology, ecology, behaviour, physiology and genetics. Here, the authors present the population ecology of Atlantic salmon and brown trout and how it is influenced by the environment in terms of growth, migration, spawning and recruitment. Salmonids appeared as freshwater fish some 50 million years ago. Atlantic salmon and brown trout evolved in the Atlantic basin, Atlantic salmon in North America and Europe, brown trout in Europe, Northern Africa and Western Asia. The species live in small streams as well as large rivers, lakes, estuaries, coastal seas and oceans, with brown trout better adapted to small streams and less well adapted to feeding in the ocean than Atlantic salmon. Smolt and adult sizes and longevity are constrained by habitat conditions of populations spawning in small streams. Feeding, wintering and spawning opportunities influence migratory versus resident lifestyles, while the growth rate influences egg size and number, age at maturity, reproductive success and longevity. Further, early experiences influence later performance. For instance, juvenile behaviour influences adult homing, competition for spawning habitat, partner finding and predator avoidance. The abundance of wild Atlantic salmon populations has declined in recent years; climate change and escaped farmed salmon are major threats. The climate influences through changes in temperature and flow, while escaped farmed salmon do so through ecological competition, interbreeding and the spreading of contagious diseases. The authors pinpoint essential problems and offer suggestions as to how they can be reduced. In this context, population enhancement, habitat restoration and management are also discussed. The text closes with a presentation of what the authors view as major scientific challenges in ecological research on these species.

Download or read book Causality and Explanation written by Wesley C. Salmon and published by Oxford University Press. This book was released on 1998-01-22 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: For over two decades Wesley Salmon has helped to shape the course of debate in philosophy of science. He is a major contributor to the philosophical discussion of problems associated with causality and the author of two influential books on scientific explanation. This long-awaited volume collects twenty- six of Salmon's essays, including seven that have never before been published and others difficult to find. Part I comprises five introductory essays that presuppose no formal training in philosophy of science and form a background for subsequent essays. Parts II and III contain Salmon's seminal work on scientific explanation and causality. Part IV offers survey articles that feature advanced material but remain accessible to those outside philosophy of science. Essays in Part V address specific issues in particular scientific disciplines, namely, archaeology and anthropology, astrophysics and cosmology, and physics. Clear, compelling, and essential, this volume offers a superb introduction to philosophy of science for nonspecialists and belongs on the bookshelf of all who carry out work in this exciting field. Wesley Salmon is renowned for his seminal contributions to the philosophy of science. He has powerfully and permanently shaped discussion of such issues as lawlike and probabilistic explanation and the interrelation of explanatory notions to causal notions. This unique volume brings together twenty-six of his essays on subjects related to causality and explanation, written over the period 1971-1995. Six of the essays have never been published before and many others have only appeared in obscure venues. The volume includes a section of accessible introductory pieces, as well as more advanced and technical pieces, and will make essential work in the philosophy of science readily available to both scholars and students.
Download or read book Messages from Frank s Landing written by Charles Wilkinson and published by University of Washington Press. This book was released on 2006-01-13 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Billy Frank, Jr., has been celebrated as a visionary, but if we go deeper and truer, we learn that he is best understood as a plainspoken bearer of traditions, a messenger, passing along messages from his father, from his grandfather, from those further back, from all Indian people, really. They are messages about the natural world, about societies past, about this society, and about societies to come. When examined rigorously - not out of any romanticism but only out of our own enlightened self-interest - these messages can be of great practical use to us in this and future years." - Charles Wilkinson, from the Introduction In 1974 Federal Judge George H. Boldt issued one of the most sweeping rulings in the history of the Pacific Northwest, affirming the treaty rights of Northwest tribal fishermen and allocating to them 50 percent of the harvestable catch of salmon and steelhead. Among the Indians testifying in Judge Boldt's courtroom were Nisqually tribal leader Billy Frank, Jr., and his 95-year-old father, whose six acres along the Nisqually River, known as Frank's Landing, had been targeted for years by state game wardens in the so-called Fish Wars. By the 1960s the Landing had become a focal point for the assertion of tribal treaty rights in the Northwest. It also lay at the moral center of the tribal sovereignty movement nationally. The confrontations at the Landing hit the news and caught the conscience of many. Like the schoolhouse steps at Little Rock, or the bridge at Selma, Frank's Landing came to signify a threshold for change, and Billy Frank, Jr., became a leading architect of consensus, a role he continues today as one of the most colorful and accomplished figures in the modern history of the Pacific Northwest. In Messages from Frank's Landing, Charles Wilkinson explores the broad historical, legal, and social context of Indian fishing rights in the Pacific Northwest, providing a dramatic account of the people and issues involved. He draws on his own decades of experience as a lawyer working with Indian people, and focuses throughout on Billy Frank and the river flowing past Frank's Landing. In all aspects of Frank's life as an activist, from legal settlements negotiated over salmon habitats destroyed by hydroelectric plants, to successful negotiations with the U.S. Army for environmental protection of tribal lands, Wilkinson points up the significance of the traditional Indian world view - the powerful and direct legacy of Frank's father, conveyed through generations of Indian people who have crafted a practical working philosophy and a way of life. Drawing on many hours spent talking and laughing with Billy Frank while canoeing the Nisqually watershed, Wilkinson conveys words of respect and responsibility for the earth we inhabit and for the diverse communities the world encompasses. These are the messages from Frank's Landing. Wilkinson brings welcome clarity to complex legal issues, deepening our insight into a turbulent period in the political and environmental history of the Northwest. "The Boldt decision profoundly changed natural resource management in the Pacific Northwest. This book clearly builds an historical base to help guide us today. The wisdom and patience of Billy Frank fill virtually every page. It is required reading for anyone interested in salmon preservation." - Governor Daniel J. Evans "Charles Wilkinson evokes the character and culture of the Nisqually people as well as their deep love for their land. From Chief Leschi to Billy Frank, we see the long thread of cultural continuity, culminating in modern times with this fight for justice." - Ada Deer (Menominee), University of Wisconsin-Madison Charles Wilkinsonis Moses Lasky Professor of Law at the University of Colorado, Boulder. He is the author ofFire on the Plateau: Conflict and Endurance in the American Southwestand numerous other books, including standard texts on Indian and Federal public land law.

Download or read book Early Life History and Recruitment in Fish Populations written by R.C. Chambers and published by Springer Science & Business Media. This book was released on 1997-07-31 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the processes influencing recruitment to an adult fish population or entry into a fishery occur very early in life. The variations in life histories and behaviours of young fish and the selective processes operating on this variation ultimately determine the identities and abundance of survivors. This important volume brings together contributions from many of the world's leading researchers from the field of fish ecology. The book focuses on three major themes of pressing importance in the analysis of the role that the early life history of fishes plays in the number and quality of recruits: the selective processes at play in their early life history; the contributions of early life history to the understanding of recruitment.
Download or read book The Senses of Fish written by Gerhard von der Emde and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish comprise more than 50% of all living vertebrates and are found in a wide range of highly diverse habitats like the deep sea, the shoreline, tide pools, tropical streams and sweetwater ponds. During evolution, the senses of fish have adapted to the physical conditions of the environment in which different species live. As a result, the senses of fish exhibit a remarkable diversity that allows different species to deal with the physical constraints imposed by their habitat. In addition, fish have evolved several `new' sensory systems that are unique to the aquatic environment. In this book, examples of adaptation and refinement are given for six sensory systems: The visual system, The auditory system, The olfactory system, The mechanosensory lateral line system, The taste system, The electrosensory system. In each case, the environmental conditions under which a particular group of fish lives are analyzed. This is followed by a description of morphology and physiology of the sensory system and by an evaluation of its perceptional capabilities. Finally, the sensory adaptations to the particular conditions that prevail in the habitat of a species are highlighted. The various examples from different groups of fish presented in this book demonstrate the impressive capability of fish sensory systems to effectively overcome physical problems imposed by the environment.

Download or read book Brilliant written by Jane Brox and published by Houghton Mifflin Harcourt. This book was released on 2010-06-29 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This “superb history” of artificial light traces the evolution of society—“invariably fascinating and often original . . . [it] amply lives up to its title” (Publishers Weekly, starred review). In Brilliant, Jane Brox explores humankind’s ever-changing relationship to artificial light, from the stone lamps of the Pleistocene to the LEDs embedded in fabrics of the future. More than a survey of technological development, this sweeping history reveals how artificial light changed our world, and how those social and cultural changes in turn led to the pursuit of more ways of spreading, maintaining, and controlling light. Brox plumbs the class implications of light—who had it, who didn’t—through the centuries when crude lamps and tallow candles constricted waking hours. She identifies the pursuit of whale oil as the first time the need for light thrust us toward an environmental tipping point. Only decades later, gas street lights opened up the evening hours to leisure, which changed the ways we live and sleep and the world’s ecosystems. Edison’s bulbs produced a light that seemed to its users all but divorced from human effort or cost. And yet, as Brox’s informative portrait of our current grid system shows, the cost is ever with us. Brilliant is infused with human voices, startling insights, and timely questions about how our future lives will be shaped by light
Download or read book Mechanisms of Migration in Fishes written by James D. McCleave and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last major synthesis of our knowledge of fish migration and the underlying transport and guidance phenomena, both physical and biological, was "Fish Migration" published 16 years ago by F.R. Harden Jones (1968). That synthesis was based largely upon what could be gleaned by classical fishery-biology techni.ques, such as tagging and recapture studies, commercial fishing statistics, and netting and trapping studies. Despite the fact that Harden Jones also provided, with a good deal of thought and speculation, a theoretical basis for studying the various aspects of fish migration and migratory orientation, progress in this field has been, with a few excepti.ons, piecemeal and more disjointed than might have been expected. Thus we welcomed the approach from the NATO Marine Sciences Programme Panel and the encouragement from F.R. Harden Jones to develop a proprosal for, and ultimately to organize, a NATO Advanced Research Institute (ARI) on mechanisms of fish migration. Substantial progress had been made with descriptive, analytical and predictive approaches to fish migration since the appearance of "Fish ~ligration." Both because of the progress and the often conflicting results of research, we felt that the time was again right and the effort justified to synthesize and to critically assess our knowledge. Our ultimate aim was to identify the gains and shortcomings and to develop testable hypotheses for the next decade or two.

Download or read book Invitation to Law Society written by Kitty Calavita and published by University of Chicago Press. This book was released on 2016-04-11 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research and real-life examples that “lucidly connect some of the divisive social issues confronting us today to that thing we call ‘the law’” (Law and Politics Book Review). Law and society is a rapidly growing field that turns the conventional view of law as mythical abstraction on its head. Kitty Calavita brilliantly brings to life the ways in which law is found not only in statutes and courtrooms but in our institutions and interactions, while inviting readers into conversations that introduce the field’s dominant themes and most lively disagreements. Deftly interweaving scholarship with familiar examples, Calavita shows how scholars in the discipline are collectively engaged in a subversive exposé of law’s public mythology. While surveying prominent issues and distinctive approaches to both law as it is written and actual legal practices, as well as the law’s potential as a tool for social change, this volume provides a view of law that is more real but just as compelling as its mythic counterpart. With this second edition of Invitation to Law and Society, Calavita brings up to date what is arguably the leading introduction to this exciting, evolving field of inquiry and adds a new chapter on the growing law and cultural studies movement. “Entertaining and conversational.” —Law and Social Inquiry
