Book Synopsis The Impact of Nitrogen Deposition on Natural and Semi-Natural Ecosystems by : S.J. Langan
Download or read book The Impact of Nitrogen Deposition on Natural and Semi-Natural Ecosystems written by S.J. Langan. This book was released on 2014-11-14. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an up-to-date synthesis of the understanding of the interaction between the emission of nitrogen, its deposition and impact on the most important components of natural and semi-natural ecosystems. The work consists of contributions from internationally renowned research scientists. Individual chapters deal with the factors and processes related to nitrogen deposition and soils, non-forest vegetation communities, forest ecosystems, and surface waters. The assessment of these impacts is discussed in terms of setting critical loads. The book is aimed at researchers, advanced course students and policy makers/advisors involved with aspects of the impact of air pollution.

Book Synopsis Partitioning of Atmospheric Nitrogen Under Long-term Reduced Atmospheric Deposition Conditions in a Norway Spruce Forest Ecosystem by : Zhuo Feng
Download or read book Partitioning of Atmospheric Nitrogen Under Long-term Reduced Atmospheric Deposition Conditions in a Norway Spruce Forest Ecosystem written by Zhuo Feng. This book was released on 2010. Available in PDF, EPUB and Kindle. Book excerpt: In the past century, anthropogenic activities have increased N input drastically to terrestrial ecosystems and influenced the global N cycle. Especially temperate forest ecosystems are affected in their productivity, species composition, soil chemistry and water quality. N input to forest ecosystems is retained in trees and soil. Excessive N is leached out or released as gases. The retention of N input in soils is mainly influenced by the stability of soil organic matter (SOM). Many forests in central Europe and North America have been subjected to N saturation, i.e. excessive N appeared as nitrate in the leachate below the rooting zone. Reduction of atmospheric N emission and consequent atmospheric N deposition is proposed to be the only practical long-term solution to improve N-saturated forest ecosystems. However, responses of N-saturated forest ecosystems to reduced atmospheric N deposition have been seldom investigated. In the present study, atmospheric deposition was manipulated through roof constructions below the canopy of a mature Norway spruce forest on the Solling plateau in central Germany. A £^(5)N tracer field and a density fractionation laboratory experiment were conducted in the present study to investigate the influence of long-term reduced atmospheric N deposition on the partitioning of atmospheric N in different forest ecosystem compartments as well as on the partitioning of atmospheric N retained in the soil in different SOM pools.

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 2023-10-22. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric Nitrogen Deposition in Global Forests: Spatial Variation, Impacts, and Management Implications provides the most 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 nitrogen deposition in global forests. The book 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. Finally, the book reviews indicators and thresholds for nitrogen saturation in global forests and analyzes remediation options to reduce impacts of excess nitrogen deposition. This 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. - Offers a systematic view of the ecological impacts of enhanced nitrogen deposition - Provides the most comprehensive knowledge on spatial variation and the ecological impacts of reactive nitrogen deposition in global forests - Presents expert research and findings on forest management options to remediate negative impacts
