Download or read book Geomorphic Processes and Riverine Habitat written by American Geophysical Union. Meeting and published by American Geophysical Union. This book was released on 2001-01-09 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Water Science and Application Series, Volume 4. Declines in fish populations and the loss of riverine habitat from human demands on the environment intensify year by year. By considering why and how, and by proposing restoration methods and mitigation strategies, scientists respond forcefully to improve disturbed ecosystems. Geomorphic Processes and Riverine Habitat presents results from recent research in fluvial geomorphology related to the assessment and characterization of riverine and riparian habitat, and the response of biota to changes in their environment. As our understanding of formative processes and how humans occupy and shape the environment grows, we can minimize our impact while enhancing our ability to restore and rehabilitate degraded river systems. For scientists, researchers and students of riverine habitat.

Download or read book Blood Types in Pacific Salmon written by George J. Ridgway and published by . This book was released on 1960 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intraspecific differences in erythrocyte antigens (blood types) were shown to occur in four species of Pacific salmon, the sockeye or red salmon (Oncorhynchus nerka), the chinook or king salmon (O. tshawytscha), the chum salmon (O. keta), and the pink salmon (O. gorbuscha). Antisalmon-erythrocyte sera prepared in rabbits and chickens were used after absorption of species-specific antibodies. Some of these blood types were shown to differ in their frequency of occurrence between different geographic races. In addition, isoimmunizations were prepared and at least eight different patterns of antigenic composition were displayed by the cells tested. These results indicate that considerable antigenic diversity exists in salmon. Reagents to detect valuable markers for the investigation of geographic races of salmon should be obtained through further research.

Available in PDF, EPUB and Kindle. Book excerpt: The Puget Sound is a complex fjord-estuary system in Washington State that is connected to the Pacific Ocean by the Juan de Fuca Strait and surrounded by several large population centers. The watershed is enormous, covering nearly 43,000 square kilometers with thousands of rivers and streams. Geological forces, volcanos, Ice Ages, and changes in sea levels make the Sound a biologically dynamic and fascinating environment, as well as a productive ecosystem. Human activity has also influenced the Sound. Humans built several major cities, such as Seattle and Tacoma, have dramatically affected the Puget Sound. This book describes the natural history and evolution of Puget Sound over the last 100 million years through the present and into the future. Key Features Summarizes a complex geological, geographical, and ecological history Reviews how the Puget Sound has changed and will likely change in the future Examines the different roles of various drivers of the Sound’s ecosystem function Includes the role of humans—both first people and modern populations. Explores Puget Sound as an example of general bay ecological and environmental issues
Download or read book Stream and Watershed Restoration written by Philip Roni and published by John Wiley & Sons. This book was released on 2012-09-18 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: With $2 billion spent annually on stream restoration worldwide, there is a pressing need for guidance in this area, but until now, there was no comprehensive text on the subject. Filling that void, this unique text covers both new and existing information following a stepwise approach on theory, planning, implementation, and evaluation methods for the restoration of stream habitats. Comprehensively illustrated with case studies from around the world, Stream and Watershed Restoration provides a systematic approach to restoration programs suitable for graduate and upper-level undergraduate courses on stream or watershed restoration or as a reference for restoration practitioners and fisheries scientists. Part of the Advancing River Restoration and Management Series. Additional resources for this book can be found at: www.wiley.com/go/roni/streamrestoration.

Download or read book Systematics Historical Ecology and North American Freshwater Fishes written by Richard L. Mayden and published by . This book was released on 1992 with total page 969 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book addresses the current need for a holistic approach in comparative and evolutionary biology and offers numerous applications of the modern methods of phylogenetic systematics and historical ecology, using the North American fish fauna as its case study. This major synthesis, the first published work of its kind, provides a theoretical and methodological foundation for future studies in ichthyology, evolutionary biology, and other fields of comparative biology." "Several introductory pieces present major statements of general principles, detailed examinations of the diversity and distributions of North American freshwater fishes, and what is known of their systematic relationships. The rest of the volume's 30 papers then contribute new phylogenetic hypotheses for a significant number of taxa. Along the way, the reader is introduced to the principles, first, of phylogenetic systematics - the reconstruction of evolutionary or ancestor-descendant relationships of groups of organisms on the basis of heritable traits - and, second, of historical ecology - a comprehensive research program that links systematics with many areas of comparative biology. Together, the two allow for the formulation of direct and testable hypotheses regarding the evolution of species and their attributes, interspecies interactions, and the formation and persistence of biotic communities. Without these methods that incorporate "historical controls," our estimates of history for all areas of biology are inefficient, indirect, and worst of all, untestable." "This book focuses on North American freshwater fishes not only because the 42 contributors know them so well but also because this highly diverse fauna is well known in so many important aspects (diversity, species distributions, life histories) relevant to evaluating general applications of the new paradigms of systematics and historical ecology. Many other faunas present interesting biotas appropriate for the preparation of a similar piece of work, but no other fauna can claim as complete a knowledge base." "The theme articulated throughout the book underscores the Darwinian proposition of descent with modification. The biological information particular to the North American freshwater fish fauna establishes an invaluable foundation for understanding diversification and advancing education and research. Moreover, the methods, theories, and empirical data presented serve as essential resources for comparative and evolutionary research programs applicable to any biota or taxonomic grouping." "The book includes some 200 illustrations, 60 tables, 10 appendixes, and comprehensive taxonomic and subject indexes."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
