Book Description
Excerpt from Analyses of Great Smoky Mountain Red Spruce Tree Ring Data Drs. Ord and Derr performed a spatial analysis on the data. They concluded that there was a tendency for ring widths to diminish in recent years and that there is a strong spatial dependence ill forecast residuals that cannot be explained by geographic or biotic factors alone. They did not consider climate, which they mention could explain some of the remaining spatial dependence. The analysis performed here is novel for the field of dendrochronology and may lead to useful results in the future.

Acid Deposition

ISBN: 3642764738
Category : Science
Languages : en
Pages : 345
Book Description
The subject of acid deposition remains one of the most urgent of our contemporary environmental problems. Research programmes are continually redefming our understanding of cause and effect and hence the continuing need for a timely and authoritative series addressing these issues. This volume seeks to review and defme our contemporary understanding of acid deposition by reference to new international data and as a consequence assist the definition of our future research requirements and policy developments. International contributions to the volume are drawn from the Federal Republic of Germany, the U.S.A., Canada, Brazil, Switzerland, Austria, Israel, France and the United Kingdom. Some of these nations have experienced acid deposition on a regional scale for considerable periods of time; for others the phenomenon is an emerging problem. This collection of papers has been compiled by invitation to eminent members of the acid deposition research community and by selection from a carefully targeted call for papers. It is primarily designed to meet the needs of researchers, lecturers and postgraduate students in environmental disciplines and for environmental policy makers. It is of interest to professionals in related disciplines and essential as a reference text for libraries. The volume is divided into four broad themes: Emissions, chemistry and deposition; Ecosystem effects (freshwater, soils and forest systems); Effects on structural materials; Mitigation, control and management. Each of these sections provides an overview of contemporary understanding, presents new experimental or field evidence and provides guidance for our future research agenda.
Ecology and Decline of Red Spruce in the Eastern United States
Author: Mary B. AdamsPublisher: Springer Science & Business Media
ISBN: 1461229065
Category : Science
Languages : en
Pages : 427
Book Description
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.
The Productivity and Sustainability of Southern Forest Ecosystems in a Changing Environment
Author: Robert MicklerPublisher: Springer Science & Business Media
ISBN: 1461221781
Category : Science
Languages : en
Pages : 892
Book Description
The research presented here provides a sound scientific basis for management and policy decisions regarding the productivity and sustainability of forest ecosystems in the context of a rapidly changing global environment. It is the synthesis of 5 years of field and laboratory research on southern forests conducted by the US Department of Agriculture Forest Service to provide scientific assessments to the US Global Change Research Program, and, as such, is invaluable for policy makers and land use managers.
