Book Description
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.

Riparian Areas
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309082951
Category : Science
Languages : en
Pages : 449
Book Description
The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Ecology
Author: Charles J. Krebs
Publisher: Benjamin-Cummings Publishing Company
ISBN: 9780321068798
Category : Science
Languages : en
Pages : 695
Book Description
This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.

High Mountain Conservation in a Changing World
Author: Jordi Catalan
Publisher: Springer
ISBN: 3319559826
Category : Nature
Languages : en
Pages : 413
Book Description
This book provides case studies and general views of the main processes involved in the ecosystem shifts occurring in the high mountains and analyses the implications for nature conservation. Case studies from the Pyrenees are preponderant, with a comprehensive set of mountain ranges surrounded by highly populated lowland areas also being considered. The introductory and closing chapters will summarise the main challenges that nature conservation may face in mountain areas under the environmental shifting conditions. Further chapters put forward approaches from environmental geography, functional ecology, biogeography, and paleoenvironmental reconstructions. Organisms from microbes to large carnivores, and ecosystems from lakes to forest will be considered. This interdisciplinary book will appeal to researchers in mountain ecosystems, students and nature professionals. This book is open access under a CC BY license.

Steppe Ecosystems
Author: Manuel B. Morales Prieto
Publisher: Nova Science Publishers
ISBN: 9781628082982
Category : Biodiversity
Languages : en
Pages : 0
Book Description
Steppe environments impose strong selection pressures on organisms due to limiting climate conditions. Biotic factors also exert important pressures on steppe organisms, which display notable and interesting adaptations. At the same time, steppes are among the most fragile and human-impacted ecosystems of the world. As a result of these ecological and conservation features, steppe ecosystems and organisms have long deserved the attention of ecologists, biogeographers and conservation biologists. Through the contribution of steppe ecology experts from different regions of the world, this volume aims to answer hot questions in steppe ecology and conservation such as how did present-day steppe ecosystems arise? Is the steppe a perfectly identifiable and homogeneous biome, or are there different types of steppes? If the latter is true, what are the abiotic and biotic factors that define steppe ecosystems? Do they function differently? In short, what is a steppe? Can we identify clearly steppe-specific taxa? Are their functional traits homogeneous across steppe ecosystems? How are their main biodiversity patterns?However, this book also responds to the current concern about the future of the worlds steppes, threatened by increasing land-use intensification, which brings out the need for their sustainable management on the basis of adequate scientific knowledge. Therefore, the chapters comprising this book not only diffuse current scientific knowledge on steppe ecosystems, which is not a minor aim, but provide cues and tools to evaluate their state and to scientifically inform and help their management. Let us hope these messages reach the adequate ears.
