Available in PDF, EPUB and Kindle. Book excerpt: Running waters are enormously diverse, ranging from torrential mountain brooks, to large lowland rivers, to great river systems whose basins occupy subcontinents. While this diversity makes river ecosystems seem overwhelmingly complex, a central theme of this volume is that the processes acting in running waters are general, although the settings are often unique. The past two decades have seen major advances in our knowledge of the ecology of streams and rivers. New paradigms have emerged, such as the river continuum and nutrient spiraling. Community ecologists have made impressive advances in documenting the occurrence of species interactions. The importance of physical processes in rivers has attracted increased attention, particularly the areas of hydrology and geomorphology, and the inter-relationships between physical and biological factors have become better understood. And as is true for every area of ecology during the closing years of the twentieth century it has become apparent that the study of streams and rivers cannot be carried out by excluding the role of human activities, nor can we ignore the urgency of the need for conservation. These developments are brought together in Stream Ecology: Structure and function of running waters, designed to serve as a text for advanced undergraduate and graduate students, and as a reference book for specialists in stream ecology and related fields.

Download or read book Wildlife habitat Relationships in Oregon and Washington written by David H. Johnson and published by . This book was released on 2001 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides information about the terrestrial, freshwater, and marine habitats of Oregon and Washington and the wildlife that depend upon them; it also supports broader and more consistent conservation planning, management, and research. The 27 chapters identify 593 wildlife species, define some 300 wildlife terms, profile wildlife communities, review introduced and extirpated species and species at risk, and discuss management approaches. The volume includes color and bandw photographs, maps, diagrams, and illustrations; and the accompanying CD-ROM contains additional wildlife data (60,000 records), maps, and seven matrixes that link wildlife species with their respective habitat types. Johnson is a wildlife biologist, engineer, and habitat scientist; and O'Neill is director of the Northwest Habitat Institute; they worked together on this publication project as its managing directors.

Download or read book Fungal Ecology written by Neville J. Dix and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fungi play vital roles in all ecosystems, as decomposers, symbionts of animals and plants and as parasites. Thus their ecology is of great interest. It has been estimated that there may be as many as 1. 5 million species of fungi, many of which are still undescribed. These interact in various ways with their hosts, with their substrates, with their competitors (including other fungi) and with abiotic variables of their environment. They show great variation in morphology, reproduction, life cycles and modes of dispersal. They grow in almost every conceivable habitat where organic carbon is available: on rock surfaces, in soil, the sea and in fresh water, at extremes of high and low temperature, on dry substrata and in concen trated solutions. Fungal ecology is therefore an enormous subject and its literature is voluminous. In view of this we have had to be selective in the material we have included in this book. We have chosen to concentrate on subjects in which we have some personal experience through either research or teaching. We preferred to tackle a few subjects in depth instead of attempting to cover a wider range of topics superficially. We are conscious of the extensive gaps in coverage: for example on the ecology of lichens, of fungal plant pathogens and of the complex interactions between fungi and animals. It is some justification that book-length treatments of these subjects are available elsewhere.
Download or read book Carabid Beetles Ecology and Evolution written by K. Desender and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Carabidae form one of the largest and best studied families of insects, occurring in nearly every terrestrial habitat. The contributions included in this book cover a broad spectrum of recent research into this beetle family, with an emphasis on various aspects of ecology and evolution. They deal both with individual carabid species, for example in studies on population and reproductive biology or life history in general, and with ground beetle communities, as exemplified in papers treating assemblages in natural habitats, on agricultural land and in forests. Disciplines range from biogeography and faunistics, over morphology, taxonomy and phylogenetics, ecophysiology and functional ecology, to population, community, conservation and landscape ecology. This volume is the result of the 8th European Carabidologists' Meeting, 2nd International Symposium of Carabidology, September 1-4, 1992, Belgium.

Download or read book Surface Climates of Canada written by Timothy R. Oke and published by McGill-Queen's Press - MQUP. This book was released on 1998-01-15 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the opening chapters contributors lay out the large-scale context of the physical climate of Canada, introducing the processes, balances, and dynamic linkages between the surface and atmosphere that create and maintain the diversity of surface climates found in Canada as well as outlining the nature of the physical processes that operate near the ground's surface. Individual chapters are dedicated to snow and ice - the almost universal surface cover in Canada - and the other major natural surface environments of Canada: ocean and coastal zones, fresh water lakes, wetlands, arctic islands, low arctic and subarctic lands, forests, and alpine environments. The final part of the book considers those surface environments that have been strongly influenced by human activity, such as agricultural lands and urban environments, and examines the prospects for future climate change. Bringing together for the first time a wide range of scholarship by leading climatologists, The Surface Climates of Canada will be an indispensable tool for understanding Canada's surface climates and the processes responsible for their creation and control.

Available in PDF, EPUB and Kindle. Book excerpt: This new edition of Whitmore's classic introduction to tropical rain forests has been comprehensively revised and updated, reflecting the changes which have taken place since it was first published in 1990. The sections on human impact have been extended, including a new global assessment of deforestation, and details of new research on biodiversity and conservation. The book remains unique in linking rain forest biology and ecology with silviculture, and with concerns over sustainable resource utilization and the future of the tropical rain forests. Accessibly written and illustrated throughout, it is a must for biology and geography students, and anyone who seeks to know more about the nature and importance of the world's tropical rain forests.
