Download or read book Encyclopedia of the World s Endangered Languages written by Christopher Moseley and published by Routledge. This book was released on 2008-03-10 with total page 946 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concern for the fast-disappearing language stocks of the world has arisen particularly in the past decade, as a result of the impact of globalization. This book appears as an answer to a felt need: to catalogue and describe those languages, making up the vast majority of the world's six thousand or more distinct tongues, which are in danger of disappearing within the next few decades. Endangerment is a complex issue, and the reasons why so many of the world's smaller, less empowered languages are not being passed on to future generations today are discussed in the book's introduction. The introduction is followed by regional sections, each authored by a notable specialist, combining to provide a comprehensive listing of every language which, by the criteria of endangerment set out in the introduction, is likely to disappear within the next few decades. These languages make up ninety per cent of the world's remaining language stocks. Each regional section comprises an introduction that deals with problems of language preservation peculiar to the area, surveys of known extinct languages, and problems of classification. The introduction is followed by a list of all known languages within the region, endangered or not, arranged by genetic affiliation, with endangered and extinct languages marked. This listing is followed by entries in alphabetical order covering each language listed as endangered. Useful maps are provided to pinpoint the more complex clusters of smaller languages in every region of the world. The Encyclopedia therefore provides in a single resource: expert analysis of the current language policy situation in every multilingual country and on every continent, detailed descriptions of little-known languages from all over the world, and clear alphabetical entries, region by region, of all the world's languages currently thought to be in danger of extinction. The Encyclopedia of the World’s Endangered Languages will be a necessary addition to all academic linguistics collections and will be a useful resource for a range of readers with an interest in development studies, cultural heritage and international affairs.

Download or read book Coastal and Deep Ocean Pollution written by Andres Hugo Arias and published by CRC Press. This book was released on 2020-03-10 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the recent decades, social, political and academic endeavours have been made to improve environmental quality and reduce pollution. In particular, the ocean, sea and coastal areas show varying degrees of impact from the multiple human activities carried out in the terrestrial as well as in the aquatic environment. Ecology is a science which studies the relationship between organisms and the surrounding environment and in the modern era, the marine world is getting increasing attention. For centuries it has been the final reservoir of human garbage; later it became an oil farm with a concomitant increase of coastal population growth and unplanned growth of the fishing industry and the increasing use of sea routes for cargo transport and recreational uses (cruises). All this led to rising contamination with negative effects on biota and even human health. It is then imperative to know the current situation of the world's oceans: that is the main purpose of this book, to document at a glance the latest research in the field of ocean pollution.

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.

Download or read book The World According To Pimm A Scientist Audits the Earth written by Stuart Pimm and published by McGraw Hill Professional. This book was released on 2001-08-10 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Take a globe-circling tour of our endangered planet with conservation biologist Stuart Pimmwho is taking stock and keeping score. We use 50 percent of the world's freshwater supply. We consume 42 percent of the world's plant growth. We are liquidating animals and plants 100 times faster than the natural rate of extinction. Such numbers should make it clear that the human impact on our planet has been, and continues to be, extreme and detrimental. Yet even after decades of awareness of our environmental peril, there remains passionate disagreement over what the problems are and how they should be remedied. Much of the impasse stems from the fact that the problems are difficult to quantify. How do we assess the impact of habitat loss on various species, when we haven't even counted them all? And just what factors go into that 42 percent of biomass we are hungrily consuming? It is only through an understanding of the numbers that we will be able to break that impasse and come to agreement. Working on the front lines of conservation biology, Stuart Pimm is one of the pioneers whose work has put the "science" in environmental science. In this book, he appoints himself "investment banker of the global, biological accounts," checking the numbers gathered by tireless scientists in work that is always painstaking and often heartbreaking. Pimm explains the numerical results in lucid prose. With wit, passion, and candor, he reveals the importance of understanding where those numbers come from and what they mean. To do so, he takes the reader on a globe-circling tour of our beautiful, but weary, planet. With Pimm as our indomitable guide, we travel from the volcanic mountains and rainforests of Hawaii to the boreal forests of Siberia. We see a blue whale off the Pacific coast of Mexico, where the blue oceans are slowly turning to barren deserts. We go birdwatching high up in the leafy canopy of the Amazon, from which we can see the hundreds of smoke plumes busily working at deforestation. At times, the view looks rather grim. But Pimm is no Cassandra; he never preaches or scolds. Ever optimistic, this book presents a world filled with mysterious beauty, the infinite variety of nature, and an urgent hope that through an understanding of our planet's environmental past and present, we will be inspired to save it from future extinction. "[T]his book is unashamedly optimistic. It is a celebration of our spectacular and fascinating world. I have made no attempt to restrain my joy as I encounter its natural history and its peoples. By the time you read the Epilogue you will know that our world is not doomed, it is not fatally wounded, but neither is it healthy. It needs attention. . . ." Stuart Pimm, from the Prologue

Available in PDF, EPUB and Kindle. Book excerpt: Haa Leelk'w Has Aan' Saaxu / Our Grandparents' Names on the Land presents the results of a collaborative project with Native communities of Southeast Alaska to record indigenous geographic names. Documenting and analyzing more than 3,000 Tlingit, Haida, and other Native names on the land, it highlights their descriptive force and cultural significance. With community maps, tables, and photographs, this book will be invaluable for those seeking to understand Alaska Native geographic perspectives. As Tlingits from the Hoonah Indian Association explain in the book: "Long before Russian, French, Spanish, and British explorers mapped and named the mountains and bays of the Huna Tlingit homeland, we identified special places in our own vibrant, descriptive ways. Tlingit place names reflect important natural resources, ancestral stories, sacred places, and major geological and historic events. Our place names describe more than just inanimate locations for we perceive the mountains, glaciers, and streams to be as alive and aware as ourselves. Rather, they capture the history, emotions, and stories of our enduring relationship with a living, evolving landscape." "The new benchmark against which all future work will be measured." -Richard Dauenhauer, author of Russians in Tlingit America "Thomas Thornton and his Tlingit colleagues show how 'grandparents' names on the land' provide exquisite scaffolding for human ecologies in North America's far northwest--a moral universe inhabited by a community of beings in constant communication and exchange. This book will be a resource for the ages." -Julie Cruikshank, author of Do Glaciers Listen? Local Knowledge, Colonial Encounters, and Social Imagination "Restoring Tlingit placenames and their meanings will root our people back in place and decolonize the landscape, and Thornton has provided us with a fundamental tool to do exactly that. Sh t--oghaa xhat ditee--I am grateful." -Lance A. Twitchell, Xh'unei, University of Alaska Southeast Thomas F. Thornton is senior research fellow and director of the Environmental Change and Management Program at the Environmental Change Institute, School of Geography and the Environment, University of Oxford He is the author of Being and Place among the Tlingit.

Download or read book Spawning Abundance of Chinook Salmon in the Taku River in 2003 written by and published by . This book was released on 2006 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cooperative study involving the Department of Fisheries and Oceans Canada, the Alaska Department of Fish and Game, and the Taku River Tlingit First Nation was conducted to estimate the number of spawning Chinook salmon Oncorhynchus tshawytscha in the Taku River in 2003 with a mark-recapture experiment. Fish were captured at Canyon Island on the lower Taku River with fish wheels from May through August and were individually marked with back-sewn, solid-core spaghetti tags. All tagged fish were also batch marked with an opercle punch plus removal of the left axillary appendage. Sampling on the spawning grounds in tributaries was used to estimate the fraction of the population that had been marked. The estimated spawning abundance of small Chinook salmon ( 400 mm long; mid-eye to fork of tail) was 3,489 (SE = 1,052). Spawning abundance of medium-size Chinook salmon (401-659 mm) was estimated to be 16,780 (SE = 2,274). Finally, spawning abundance of large-size fish (= 660 mm) was estimated to be 36,435 (SE = 6,705), and the estimated total of all fish was 56,704 (SE = 7,158). The sum of the peak aerial survey counts of large spawning Chinook salmon conducted at five index tributaries of the Taku River was 16% of the mark-recapture estimate. Age 1.3 fish (1998 brood year) constituted an estimated 40% of the spawning population, followed by age 1.2 fish (1999 brood year), which constituted an estimated 29% of the population
