This book was released on 1993 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Up-to-date information, knowledge and research in progress in scientific fields related to natural production of juvenile Atlantic salmon and some other ecologically similar fluvial salmonids is contained in the 25 papers and 12 abstracts contained in this publication, which were prepared for an international symposium held in St. John's, Newfoundland. Studies relate to stream ecology, invertebrates and predators, habitat improvement, competitive effects, behaviour and dispersal, habitat and production of juvenile salmon, population dynamics and relationships of juvenile salmon estimates to smolt yields. A list of participants at the conference is also provided.

Download or read book The Atlantic Salmon in the History of North America written by R. W. Dunfield and published by Fisheries and Oceans, Scientific Information and Publications Branch. This book was released on 1985 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atlantic salmon (Salmo salar) has occupied a salient position in the history of eastern North America for at least the past 1000 years. Initially the species occupied a prominant niche in the prolific web of life that existed throughout its former occurrence area; millions of pounds of salmon were produced annually from the freshwater streams between New York and Ungava - a resource that was a principal food source for the Amerindian cultures which shared its range. In a chronological and cumulative way, the salmon became an increasingly important factor in both the domestic and commercial life of the developing colonies; it provided a recreational outlet for the sportsman, and evolved as a principal object of intellectual and scientific investigation. The documented specifics of the salmon's history, however, are largely comprised of repetitive instances of overexploitation, careless destruction of stocks and their environment, and ineffectual conservation actions. Despite the species' former importance, its more recent history is one of declining presence, and its destiny appears to be extinction. By documenting this story of discovery, exploitation, and decline, the urgent need for the employment of sound resource management practices to preserve the salmon is emphasized.

Available in PDF, EPUB and Kindle. Book excerpt: The book describes the main marine and coastal biological systems of Passamaquoddy Bay and adjacent waters and the oceanographic and meteorological characteristics of the area. Subject areas begin with meteorolgy and oceanography. The second group covers the intertidal systems with chapters on rocky intertidal shores, rock pools, coarse sedimentary shores and salt marshes. The third general section covers hard and sedimentary sublittoral habitats. Following chapters discuss pelagic systems under the headings fishes, phytoplankton, larger zooplankton, and microzooplankton. Three chapters deal with the birds, amphibians and reptiles, and marine mammals. Finally coastal vegetation is described.
Download or read book Our Landscape Heritage written by Vincent Frank Zelazny and published by . This book was released on 2007 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our Landscape Heritage provides an overview of the history and ecological makeup of the landscapes of New Brunswick to help ecological seekers starting out with basic knowledge about geology, soils, climate, and vegetation, to better understand why plants and animals are today distributed as they are. Part I outlines the rationale and history of ecological land classification (ELC) in New Brunswick, and presents basic scientific concepts and facts that help the reader to interpret the information that follows. Part II, Portrait of New Brunswick Ecoregions and Ecodistricts presents a detailed look at the variety and distribution of ecosystems across the geographic expanse of New Brunswick. Each of the seven chapters of Part II provides a high level description of the ecoregion, followed by detailed descriptions of each ecodistrict within the ecoregion.--Includes text from document.
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.
