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.

Book excerpt: Enhanced by many photographic illustrations of extraordinaryquality, this textbook will provide students with a completeintroduction to the scientific study of environments dominated by snowand ice. Glacial environments are scenically and scientifically amongthe most exciting on Earth, and at the same time they are among themost complex. Apart from the processes associated directly with movingice, other processes -- fluvial, acolian, lacustrine, and marine --frequently interact with ice. Glacial environments therefore exhibit awide variety of landforms and sediment associations. Today, some ten per cent of the land surface of the Earth is coveredby ice, whereas in the Pleistocene the figure exceeded thirty per cent.In earlier geological history, the Earth underwent glaciations ofcontinent-wide extent on several occasions, some of them even moreintense than those of the Pleistocene. By examining the processesoperating within glacial settings and their resulting products,Glacial Environments provides the foundation for investigationof both the ancient and the modern record. Emphasizing the range of erosional and depositional landforms,drawing on the older geological record, according due attention to theexciting recent developments in research on the marine environment,incorporating illustrations from both contemporary and ancientenvironments and covering all relevant parts of the world, thisattractive book will find a wide readership among students ofgeography, geology and environmental science.

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.
