Book Synopsis Coastal and Deep Ocean Pollution by : Andres Hugo Arias
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.

Book Synopsis Encyclopedia of the World's Endangered Languages by : Christopher Moseley
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.
Book Synopsis Physiological Ecology of Pacific Salmon by : Cornelis Groot
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.

Book Synopsis Global Change in Marine Systems by : Patrice Guillotreau
Download or read book Global Change in Marine Systems written by Patrice Guillotreau and published by Routledge. This book was released on 2017-11-13 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global Change in Marine Systems analyses and appraises societal and governing responses to change affecting marine social and ecological systems around the world. Acknowledging the stakes – local societies that depend on marine systems for food, livelihoods and wellbeing can suffer great hardship – this book highlights and explains similarities and distinctions between successful and unsuccessful responses. The book presents an analytical framework (‘I-ADApT’) that enables decision-makers to consider possible responses to global change based on experiences elsewhere. Here an international group of researchers from the natural and social sciences apply the ‘I-ADApT’ framework to twenty enlightening case studies, covering a wide range of marine systems challenged by critical global change issues around the world. The innovative research presented here guides marine system researchers, policymakers, decision-makers and practitioners in responding to global change in a timely and appropriate manner. It will appeal to students and researchers interested in environmental studies, natural resources, marine resources, environmental sociology, sustainability, and climate change.

Book Synopsis The World According To Pimm: A Scientist Audits the Earth by : Stuart Pimm
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
