Download or read book The Ecological Importance of Mixed Severity Fires written by Dominick A. DellaSala and published by Elsevier. This book was released on 2015-06-08 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ecological Importance of High-Severity Fires, presents information on the current paradigm shift in the way people think about wildfire and ecosystems. While much of the current forest management in fire-adapted ecosystems, especially forests, is focused on fire prevention and suppression, little has been reported on the ecological role of fire, and nothing has been presented on the importance of high-severity fire with regards to the maintenance of native biodiversity and fire-dependent ecosystems and species. This text fills that void, providing a comprehensive reference for documenting and synthesizing fire's ecological role. - Offers the first reference written on mixed- and high-severity fires and their relevance for biodiversity - Contains a broad synthesis of the ecology of mixed- and high-severity fires covering such topics as vegetation, birds, mammals, insects, aquatics, and management actions - Explores the conservation vs. public controversy issues around megafires in a rapidly warming world

Download or read book After the Fires written by Linda L. Wallace and published by Yale University Press. This book was released on 2004-01-01 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Americans currently choose their president through the electoral college, an extraordinarily complex mechanism that may elect a candidate who does not receive the most votes. In this provocative book, George Edwards III argues that, contrary to what supporters of the electoral college claim, there is no real justification for a system that might violate majority rule. Drawing on systematic data, Edwards finds that the electoral college does not protect the interests of small states or racial minorities, does not provide presidents with effective coalitions for governing, and does little to protect the American polity from the alleged harms of direct election of the president. In fact, the electoral college distorts the presidential campaign so that candidates ignore most small states and some large ones and pay little attention to minorities, and it encourages third parties to run presidential candidates and discourages party competition in many states. Edwards demonstrates effectively that direct election of the president without a runoff maximizes political equality and eliminates the distortions in the political system caused by the electoral college.

Download or read book Yellowstone and the Biology of Time written by Mary Meagher and published by University of Oklahoma Press. This book was released on 1999-02-01 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Established in 1872, Yellowstone National Park is the oldest and one of the largest national parks in the world. In this remarkable book, scientists Mary Meagher and Douglas B. Houston present 100 sets of photographs that compare the Yellowstone of old with the park of today. Most of the photo sets include three pictures-not the usual two-with many of the original views dating back to the 1870s and 1880s. From the same photo points used by early photographers, Meagher and Houston rephotographed the scenes in the 1970s, and then, following the great fires of 1988, again in the 1990s. The result is an illuminating record of Yellowstone's dynamic ecosystem and its changes over time. Through close analysis of the photos and reference to the vast amount of available data, Meagher and Houston describe changes in vegetation, growth of wildlife populations, the effect of beaver occupancy on wetland areas, and geothermal and elevational shifts. At the same time they point out the extent to which many sites have not changed-despite important switches in park policy and an increase in human activity. Yellowstone National Park has long been the focus of major ecological debates. Should managers allow wildfires to burn? Should the elk and bison populations be controlled? Are too many people visiting the park? Yellowstone And The Biology Of Time offers a wealth of information to help us answer these questions. A visual treasure, this book will be of value to scientists from various disciplines as well as to the many people who care about Yellowstone and other protected wilderness areas around the world.

Download or read book Fire and Climatic Change in Temperate Ecosystems of the Western Americas written by Thomas T. Veblen and published by Springer Science & Business Media. This book was released on 2006-05-10 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both fire and climatic variability have monumental impacts on the dynamics of temperate ecosystems. These impacts can sometimes be extreme or devastating as seen in recent El Nino/La Nina cycles and in uncontrolled fire occurrences. This volume brings together research conducted in western North and South America, areas of a great deal of collaborative work on the influence of people and climate change on fire regimes. In order to give perspective to patterns of change over time, it emphasizes the integration of paleoecological studies with studies of modern ecosystems. Data from a range of spatial scales, from individual plants to communities and ecosystems to landscape and regional levels, are included. Contributions come from fire ecology, paleoecology, biogeography, paleoclimatology, landscape and ecosystem ecology, ecological modeling, forest management, plant community ecology and plant morphology. The book gives a synthetic overview of methods, data and simulation models for evaluating fire regime processes in forests, shrublands and woodlands and assembles case studies of fire, climate and land use histories. The unique approach of this book gives researchers the benefits of a north-south comparison as well as the integration of paleoecological histories, current ecosystem dynamics and modeling of future changes.

Download or read book Disturbance and Ecosystems written by H. A. Mooney and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: The earth's landscapes are being increasingly impacted by the activities of man. Unfortunately, we do not have a full understanding of the consequences of these disturbances on the earth's productive capacity. This problem was addressed by a group of French and U.S. ecologists who are specialists at levels of integration extending from genetics to the biosphere at a meeting at Stanford, California, sponsored by the National Science Foundation and the Centre National de la Recherche Scientifique. With a few important exceptions it was found at this meeting that most man-induced disturbances of ecosystems can be viewed as large scale patterns of disturbances that have occurred, generally on a small scale, in ecosystems through evolutionary time. Man has induced dramatic large-scale changes in the environment which must be viewed at the biosphere level. Acid deposition and CO increase are two 2 examples of the consequences of man's increased utilization of fossil fuels. It is a matter of considerable concern that we cannot yet fully predict the ecological consequences of these environmental changes. Such problems must be addressed at the international level, yet substantive mechanisms to do this are not available.

Book excerpt: “An eclectic, enjoyable mix of literature reviews, personal experience and case studies, and practical advice from . . . leaders in their subdisciplines.” —Eleanor J. Sterling, Chief Conservation Scientist, Center for Biodiversity & Conservation, American Museum of Natural History With the US National Park Service over one hundred years old, parks and protected areas worldwide are under increasing threat from storms and fires of greater severity, plant and animal extinctions, the changing attitudes of a public that has become more urbanized, and the political pressures of narrow special interest groups. In the face of such rapid environmental and cultural changes, Science, Conservation, and National Parks gathers a group of renowned scholars—including Edward O. Wilson, Jane Lubchenco, Thomas Dietz, and Monica Turner—who address these problems and in the hope of securing a future for protected areas that will push forward the frontiers of biological, physical, and social science in and for parks. Contributors provide answers to a number of key conservation questions, such as: How should stewardship address climate change, urban encroachment and pollution, and invasive species? How can society, especially youth, become more engaged with nature and parks? What are appropriate conservation objectives for parks in the Anthropocene? Charting a course for the parks of the next century, Science, Conservation, and National Parks catalyzes the continued evolution of US park conservation policy, and serves as an inspiration for parks, conservation, and management worldwide. “Offers a refreshing holistic treatment of the linkages and mutual dependencies between parks and science. Compelling.” —William B. Monahan, USDA Forest Service and formerly of the US National Park Service “This is a testament to what can be achieved by determined conservationists.” —Biodiversity and Conservation journal

This book was released on 2023-12-05 with total page 1169 pages. Available in PDF, EPUB and Kindle. Book excerpt: 65,000 years ago, modern humans arrived in Australia, having navigated more than 100 km of sea crossing from southeast Asia. Since then, the large continental islands of Australia and New Guinea, together with smaller islands in between, have been connected by land bridges and severed again as sea levels fell and rose. Along with these fluctuations came changes in the terrestrial and marine environments of both land masses. The Oxford Handbook of the Archaeology of Indigenous Australia and New Guinea reviews and assembles the latest findings and ideas on the archaeology of the Australia-New Guinea region, the world's largest island-continent. In 42 new chapters written by 77 contributors, it presents and explores the archaeological evidence to weave stories of colonisation; megafaunal extinctions; Indigenous architecture; long-distance interactions, sometimes across the seas; eel-based aquaculture and the development of techniques for the mass-trapping of fish; occupation of the High Country, deserts, tropical swamplands and other, diverse land and waterscapes; and rock art and symbolic behaviour. Together with established researchers, a new generation of archaeologists present in this Handbook one, authoritative text where Australia-New Guinea archaeology now lies and where it is heading, promising to shape future directions for years to come.
