Download or read book Long-term Ecological Research written by Michael R. Willig and published by Oxford University Press. This book was released on 2016 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the broader impacts arising from collaborative and multidisciplinary participation in the Long-Term Ecological (LTER) Program with regard to personal perspectives, attitudes, and practices. A series of retrospective essays addresses probing questions to uncover the extent to which participation has affected the ways that scientists conduct research, educate students, or provide outreach. Concluding chapters integrate and synthesize the findings from the essays from historical, behavioral, sociological perspectives.

Download or read book Natural Sinks of CO2 written by Joe Wisniewski and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the attention with respect to the increase in atmospheric greenhouse gas concentrations centers around three issues: human-generated sources of carbon, mostly from burning fossil fuels; tropical deforestation, which accelerates the production of atmospheric carbon while causting havoc with biodiversity and the economic development of tropical countries; and the temperature increase that may accompany increased atmospheric greenhouse gas concentrations. This is the first book to focus extensively on the reverse to emissions of carbon dioxide (CO2), i.e. the sequestering of atmospheric carbon by aquatic and terrestrial ecosystems. Natural ecosystems are currently sequestering carbon and it is economically feasible to manage existing and additional terrestrial (forest, soil, saline land) and aquatic (coastal, wetland and ocean) ecosystems to substantially increase the level of carbon storage. The prospect of managing natural systems to absorb additional carbon should begin to change the mindset under which scientists, policy makers and society deal with the issue of further greenhouse gas increases.

Download or read book USDA Forest Service Experimental Forests and Ranges written by Deborah C. Hayes and published by Springer. This book was released on 2014-07-22 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: USDA Forest Service Experimental Forests and Ranges (EFRs) are scientific treasures, providing secure, protected research sites where complex and diverse ecological processes are studied over the long term. This book offers several examples of the dynamic interactions among questions of public concern or policy, EFR research, and natural resource management practices and policies. Often, trends observed – or expected -- in the early years of a research program are contradicted or confounded as the research record extends over decades. The EFRs are among the few areas in the US where such long-term research has been carried out by teams of scientists. Changes in society’s needs and values can also redirect research programs. Each chapter of this book reflects the interplay between the ecological results that emerge from a long-term research project and the social forces that influence questions asked and resources invested in ecological research. While these stories include summaries and syntheses of traditional research results, they offer a distinctly new perspective, a larger and more complete picture than that provided by a more typical 5-year study. They also provide examples of long-term research on EFRs that have provided answers for questions not even imagined at the time the study was installed.

Download or read book Tropical Forests: Management and Ecology written by Ariel E. Lugo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forestry professors used to remind students that, whereas physicians bury their mistakes, foresters die before theirs are noticed. But good institutions live longer than the scientists who contribute to building them, and the half-century of work of the USDA Forest Service's Institute of Tropical Forestry (ITF) is in plain view: an unprecedented corpus of accomplishments that would instill pride in any organization. There is scarcely anyone interested in current issues of tropical forestry who would not benefit from a refresher course in ITF's findings: its early collaboration with farmers to establish plantations, its successes in what we now call social forestry, its continuous improvement of nursery practices, its screening trials of native species, its development of wood-processing technologies appropriate for developing countries, its thorough analysis of tropical forest function, and its holistic approach toward conservation of endangered species. Fortunately, ITF has a long history of information exchange through teaching; like many others, I got my own start in tropical forest ecology fromjust such a course in Puerto Rico. And long before politicians recognized the global importance of tropical forestry, the ITF staff served actively as ambassadors of the discipline, visiting tropical coun tries everywhere to learn and, when invited to do so, to help solve local problems. It is a general principle of biogeography that species' turnover rates on islands are higher than those on continents. Inevitably, the same is true of scientists assigned to work on islands.

Download or read book New Perspectives on Nitrogen Cycling in the Temperate and Tropical Americas written by Alan R. Townsend and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inputs of nitrogen to terrestrial and aquatic ecosystems have increased several-fold over the last one hundred and fifty years, with the steepest increases during the last four decades. The expansion of fertilizer manu facture and use, the increase in fossil fuel combustion, the intensification of animal husbandry, and widespread cultivation of N2 fixing crops have all contributed to the dramatic increase in N inputs. The increase has been most rapid in Northern Hemisphere (NH) temperate ecosystems, but presently subtropical and tropical regions of Asia are also experiencing an explosive increase in N inputs to terrestrial ecosystems (W. Chameides, pers. comm. ; Galloway et al. 1996). Projected increases in N deposition for these trop ical and subtropical regions, with a high natural background of N inputs, exceed increases projected for temperate and arctic regions (Cleveland et al. submitted; Galloway et al. 1994; Holland & Lamarque 1997a). Compared to biological N fixation, N deposition is becoming a proportionately greater source of N to terrestrial and aquatic ecosystems worldwide (Vitousek et al. 1997). 6 The nitrogen contained in the atmosphere as N , 3. 9 * 10 Tg (Tg = 2 12 10 g), is the largest reservoir of N in the Earth system (Warneck 1988). However, this paper focuses on the nitrogen emissions and deposition that have been transformed from N2 into reactive forms that are biologically avail able (e. g. Vitousek et al. 1997).

Download or read book Forest Canopies written by Margaret Lowman and published by Academic Press. This book was released on 2004-09 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: The treetops of the world's forests are where discovery and opportunity abound, however they have been relatively inaccessible until recently. This book represents an authoritative synthesis of data, anecdotes, case studies, observations, and recommendations from researchers and educators who have risked life and limb in their advocacy of the High Frontier. With innovative rope techniques, cranes, walkways, dirigibles, and towers, they finally gained access to the rich biodiversity that lives far above the forest floor and the emerging science of canopy ecology. In this new edition of Forest Canopies, nearly 60 scientists and educators from around the world look at the biodiversity, ecology, evolution, and conservation of forest canopy ecosystems. Comprehensive literature list State-of-the-art results and data sets from current field work Foremost scientists in the field of canopy ecology Expanded collaboration of researchers and international projects User-friendly format with sidebars and case studies Keywords and outlines for each chapter
