Book excerpt: Excerpt from Atmospheric Deposition and Eastern Forests: Cooperative Research Starting somewhere in the boilers of factories and power plants, in the cylinders of our cars, and even in our home furnaces, sulfur and nitrogen are oxidized and are either released into the atmosphere as air pollutants, or interact with sunlight to form ozone. Buoyed by the winds, and nourished in chemically rich clouds, sulfur and nitrogen are converted into sulfuric and nitric acids. Once these compounds mix with moisture, they fall to the earth in the form of acid precipita tion, popularly known as acid rain. Acid rain - the name evokes a distressing image. Lnnocent raindrops that fall from the heavens to regenerate life in all its forms, instead, slowly and insidiously, burn the essence out of our lakes and streams and trees and soils. The popular media has exploited this image to get the public's attention; it is an image that distorts the facts about acid precipitation.

Download or read book Atmospheric Deposition and Forest Nutrient Cycling written by Dale W. Johnson and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 726 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade there has been considerable interest in the effects of atmospheric deposition on forest ecosystems. This volume summarizes the results of the Integrated Forest Study (IFS), one of the most comprehensive research programs conducted. It involved intensive measurements of deposition and nutrient cycling at seventeen diverse forested sites in the United States, Canada, and Norway. The IFS is unique as an applied research project in its complete, ecosystem-level evaluation of nutrient budgets, including significant inputs, outputs, and internal fluxes. It is also noteworthy as a more basic investigation of ecosystem nutrient cycling because of its incorporation of state-of-the-art methods, such as quantifying dry and cloud water deposition. Most significantly, the IFS data was used to test several general hypotheses regarding atmospheric deposition and its effects. The data sets also allow for far-reaching conclusions because all sites were monitored over the same period using comparable instruments and standardized protocols.
Download or read book Ecology and Decline of Red Spruce in the Eastern United States written by Mary B. Adams and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1980s there were several published reports of recent, unexplained increases in mortality of red spruce in the Adirondack Mountains and the northern Appalachian Mountains of the eastern United States. These reports coincided with documentation of reductions in radial growth of several species of pine in the southeastern United States, and with the severe, rapid, and widespread decline of Norway spruce, silver fir, and some hardwoods in central Europe. In all of these instances, atmospheric deposition was hypothesized as the cause of the decline. (Throughout this volume, we use the term "decline" to refer to a loosely synchronized regional-scale deterioration of tree health which is brought about by a combination of stress factors. These may be biotic or abiotic in nature, and the combinations may differ from site to site. ) Heated public debate about the causes and possible cures for these forest declines ensued. Through the course of this debate, it became clear that information about forest health and air pollution effects on forests was inadequate to meet policymakers' needs. Ecology and Decline of Red Spruce in the Eastern United States addresses that gap for eastern spruce fir forests and represents the culmination of a great deal of research conducted in recent years. The focus is on red spruce because the decline of red spruce was both dramatic and inexplicable and because of the great amount of information gathered on red spruce.

This book was released on 2012-12-06 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five years of research carried out by the U.S. Department of Agriculture Forest Services' Northern Global Change Program, contributing to our understanding of the effects of multiples stresses on forest ecosystems over multiple spatial and temporal scales. At the physiological level, reports explore changes in growth and biomass, species composition, and wildlife habitat; at the landscape scale, the abundance distribution, and dynamics of species, populations, and communities are addressed. Chapters include studies of nutrient depletion, climate and atmospheric deposition, carbon and nitrogen cycling, insect and disease outbreaks, biotic feedbacks with the atmosphere, interacting effects of multiple stresses, and modeling the regional effects of global change. The book provides sound ecological information for policymakers and land-use planners as well as for researchers in ecology, forestry, atmospheric science, soil science and biogeochemistry.

This book was released on 2013-06-29 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: T. C. Hutchinson The NATO Advanced Research Workshop detailed in this volume was held in Toronto, Canada, in 1985. The purpose of the Workshop was to provide a "state of the art" report on our knowledge of the sensitivities and responses of forests, wetlands and crops to airborne pollutants. Approximately 40 scientific experts from nine countries participated. Most participants were actively involved in research concerning the effects of air pollutants on natural or agro-ecosystems. These pollutants included acidic deposition, heavy metal particulates, sulphur dioxide, ozone, nitrogen oxides, acid fogs and mixtures of these. Also invited were experts on various types of ecosystem stresses, physiologi cal mechanisms pertinent to acid deposition, and other areas that were felt by the director to be of direct relevance, including: effects of ethylene on vegetation, the physiology of drought in trees, the nature and role of plant cuticles as barriers to acid rain penetration, the use of dendrochronological techniques in reconstructing the time of onset and the subsequent progression of growth declines, the ability of soils to naturally generate acidity, the role of Sphagnum moss in natural peat land acidity, the use of lichens as indicators of changing air quality, and the magnitude of natural emissions of reduced sulphur gases from tropical rainforests and temperate deciduous forests. The Workshop included a series of invited presentations and subsequent group discussions. These presentations were designed to allow syntheses of our present knowledge as well as detailed questioning and discussion.

This book was released on 2012-12-06 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The public's attitude toward air pollution in the United States evolved substantially during the 1960s. One of the results of the nation's emerging environmental ethic was the creation of the U. S. Environmental Protection Agency (EPA) in December of 1970. Prior to this time, research was focused on the impacts of air pollution on human health and welfare and was largely conducted by several federal research agencies, which included the Department of Health, Education, and Welfare; the National Oceanic and Atmospheric Administration; and the U. S. Department of Agricul ture. After the creation of the EPA, much of this work was consolidated in one regulatory agency, which resulted in periodic evaluations of the various effects of atmospheric pollution on human health, materials, agriculture, and forest ecosystems. At the same time that environmental interest was growing in the United States, concern increased in the European scientific community and public over the ecological impacts of acidic deposition. As the magnitude of the damage to European lakes and streams and the widespread decline in Norway spruce and silver fir was reported, concern that similar problems were occurring in the United States increased substantially. This concern was heightened by press reports of high elevation spruce-fir forest declines in the Adirondack and Appalachian Mountains and the decline and death of sugar maples in the northeastern United States and Canada.
