Book Synopsis Atmospheric Nitrogen Deposition to Global Forests by : Enzai Du
Download or read book Atmospheric Nitrogen Deposition to Global Forests written by Enzai Du. This book was released on 2023-02-15. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric Nitrogen Deposition in Global Forests: Spatial Variation, Impacts, and Management Implications provides the most updated and comprehensive knowledge on spatial variation and ecological impacts of reactive nitrogen deposition in global forests, as well as forest management options to mitigate the negative impacts. Written and edited by international experts in the field, this book synthesizes recent research developments and insights in monitoring and modeling of nitrogen deposition in global forests. It also assesses ecological impacts of enhanced nitrogen deposition on forest structure and function, and responses of forest ecosystems to decreasing nitrogen deposition in regions such as the European Union and North America. This book also reviews indicators and thresholds for nitrogen saturation in global forests and analyzes remediation options to reduce impacts of excess nitrogen deposition. Atmospheric Nitrogen Deposition in Global Forests: Spatial Variation, Impacts, and Management Implications is an important resource for researchers in forestry and biodiversity conservation, as well as graduate students, policymakers and others who want to understand environmental issues of reactive nitrogen deposition in global forests. Presents spatial variation of nitrogen deposition in forests at global scale Offers a systematic view of ecological impacts of enhanced nitrogen deposition Discusses responses of forest ecosystems r to decreasing nitrogen deposition Provides expert research and findings on forest management options to remediate negative impacts

Book Synopsis Critical Nitrogen Deposition Loads in High-elevation Lakes of the Western US Inferred from Paleolimnological Records by : Jasmine E. Saros
Download or read book Critical Nitrogen Deposition Loads in High-elevation Lakes of the Western US Inferred from Paleolimnological Records written by Jasmine E. Saros. This book was released on 2010. Available in PDF, EPUB and Kindle. Book excerpt: Critical loads of nitrogen (N) from atmospheric deposition were determined for alpine lake ecosystems in the western US using fossil diatom assemblages in lake sediment cores. Changes in diatom species over the last century were indicative of N enrichment in two areas, the eastern Sierra Nevada, starting between 1960 and 1965, and the Greater Yellowstone Ecosystem, starting in 1980. In contrast, no changes in diatom community structure were apparent in lakes of Glacier National Park. To determine critical N loads that elicited these community changes, we modeled wet nitrogen deposition rates for the period in which diatom shifts first occurred in each area using deposition data spanning from 1980 to 2007. We determined a critical load of 1.4 kg N ha-1 year-1 wet N deposition to elicit key nutrient enrichment effects on diatom communities in both the eastern Sierra Nevada and the Greater Yellowstone Ecosystem.

Book Synopsis Air Pollution and Its Impacts on U.S. National Parks by : Timothy J. Sullivan
Download or read book Air Pollution and Its Impacts on U.S. National Parks written by Timothy J. Sullivan. This book was released on 2017-02-03. Available in PDF, EPUB and Kindle. Book excerpt: A variety of air pollutants are emitted into the atmosphere from human-caused and natural emissions sources throughout the United States and elsewhere. These contaminants impact sensitive natural resources in wilderness, including the national parks. The system of national parks in the United States is among our greatest assets. This book provides a compilation and synthesis of current scientific understanding regarding the causes and effects of these pollutants within national park lands. It describes pollutant emissions, deposition, and exposures; it identifies the critical (tipping point) loads of pollutant deposition at which adverse impacts are manifested.

Book Synopsis Atmospheric Nitrogen Deposition in the Western United States by : Sarah Marie Anderson
Download or read book Atmospheric Nitrogen Deposition in the Western United States written by Sarah Marie Anderson. This book was released on 2017. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenic activities have greatly modified the way nitrogen moves through the atmosphere and terrestrial and aquatic environments. Excess reactive nitrogen generated through fossil fuel combustion, industrial fixation, and intensification of agriculture is not confined to anthropogenic systems but leaks into natural ecosystems with consequences including acidification, eutrophication, and biodiversity loss. A better understanding of where excess nitrogen originates and how that changes over time is crucial to identifying when, where, and to what degree environmental impacts occur. A major route into ecosystems for excess nitrogen is through atmospheric deposition. Excess nitrogen is emitted to the atmosphere where it can be transported great distances before being deposited back to the Earth's surface.
