Download or read book Reforestation Trials and Secondary Succession with Three Levels of Overstory Shade in the Grand Fir Mosaic Ecosystem written by Dennis E. Ferguson and published by . This book was released on 2005 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grand Fir Mosaic habitats are difficult to regenerate because of pocket gophers (Thomomys talpoides) and successional plant communities dominated by bracken fern (Pteridium aquilinum) and western coneflower (Rudbeckia occidentalis). This study tested reforestation practices recommended by previous research, tested hypotheses about the effects of overstory shade on regeneration success, and documented secondary succession. Natural regeneration is not a reliable reforestation method on Grand Fir Mosaic sites. Clearcut and planting was the best regeneration method if pocket gophers are controlled. Partial cutting and planting was the best regeneration method if pocket gophers were not controlled. Most gopher-caused seedling mortality occurred the first summer, first winter, and second winter after planting. The clearcut treatment resulted in the loss of shrub species and the dominance of bracken fern and/or western coneflower. In the partial cut treatment, shrubs were retained and there was less bracken fern and/or western coneflower than in the clearcut treatment.

Book excerpt: That is what this book is about. It is a framework for planning, in which habitat is the key to managing wildlife and making forest managers accountable for their actions. This book is based on the collective knowledge of one group of resource professionals and their understanding about how wildlife relate to forest habitats. And it provides a longoverdue system for considering the impacts of changes in forest structure on all resident wildlife.

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 Physiological Ecology of North American Plant Communities written by Brain F. Chabot and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although, as W.D. Billings notes in his chapter in this book. the development of physiological ecology can be traced back to the very beginnings of the study of ecology it is clear that the modern development of this field in North America is due in the large part to the efforts of Billings alone. The foundation that Billings laid in the late 1950s came from his own studies on deserts and subsequently arctic and alpine plants, and also from his enormous success in instilling enthusiasm for the field in the numerous students attracted to the plant ecology program at Duke University. Billings' own studies provided the model for subsequent work in this field. Physiological techniques. normally confined to the laboratory. were brought into the field to examine processes under natural environmental conditions. These field studies were accompanied by experiments under controlled conditions where the relative impact of various factors could be assessed and further where genetic as opposed to environmental influences could be separated. This blending of field and laboratory approaches promoted the design of experiments which were of direct relevance to understanding the distribution and abundance of plants in nature. Physiological mechanisms were studied and assessed in the context of the functioning of plants under natural conditions rather than as an end in itself.

Download or read book High Mountain Conservation in a Changing World written by Jordi Catalan and published by Springer. This book was released on 2017-08-03 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Landscape Heterogeneity and Disturbance written by Monica G. Turner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landscape pattern is generated by a variety of processes, including disturbances. In turn, the heterogeneity of the landscape may enhance or retard the spread of disturbance. The complex relationship between landscape pattern and disturbance is the subject of this book. It is designed to present an illustrative analysis of the topic, presenting the perspectives of several different disciplines. The book includes conceptual considerations, empirical studies, and management examples. Important features include: hypotheses about the spread of disturbance and the effects of scale changes in landscape studies; the multidisciplinary approach; and the explicit focus on the landscape level. The intended audience comprises graduate students, academics, and professionals interested in landscape ecology. The reader will receive a state-of-the-art treatment of a current topic in landscape ecology.
