Download or read book Tree Rings as Indicators of Ecosystem Health written by Timothy E. Lewis and published by Springer. This book was released on 1995 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the principles and applications of dendrochronology and dendrochemistry. It illustrates how these approaches are used to determine the history of natural and anthropogenic stresses on forest ecosystems and to evaluate the present status of the health of ecosystems. ****This abstract needs to be reworked**** This book is a combination of dendrochronology and dendrochemistry. Trees record the passage of each year by the formation of annual rings. The elements deposited in the wood serve as historical records of past environmental change due to global climate change, acidic deposition, heavy metal deposition, ground water contamination, and many other anthropogenic stresses. Dendrochemistry is currently being used as an indicator of forest health in the joint U.S. EPA/U.S. Forest Service long-term monitoring program called Forest Health Monitoring.

Download or read book Forest Health written by John L. Innes and published by Oxford University Press, USA. This book was released on 1993 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book assesses the current state of knowledge about forest declines, particularly as they relate to air pollution. Many declines are shown to be unrelated to air pollution and, in other cases, the links between air pollution and the condition of the trees is extremely tenuous. Factors such as nutrient depletion due to past management practices and drought are shown to have had a major influence on the health of trees. In many cases, the evidence for a decline in tree condition is at best ambiguous, and much of the concern appears to have been generated by political and media interest rather than by a critical evaluation of the available data. A detailed examination of the comprehensive data collected in the British forest health monitoring program over the last five years indicates the complexity of the process involved and illustrates the dangers of taking data from a single year at face value. Many of the indices used to assess trees are of questionable value when compared over time or space, as their subjective nature precludes any reliable comparisons. Studies of annual increment and wood quality indicate that the international market for timber is unlikely to be affected in either the long or the short term.
Download or read book Growth Dynamics of Conifer Tree Rings written by Eugene A. Vaganov and published by Springer Science & Business Media. This book was released on 2006-03-12 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dendrochronologists have long estimated the impact of climate on tree-ring growth by empirical-statistical methods. The use of the model is illustrated with examples from widely differing environments, and possible future directions for model development and application are discussed. As forests are the main carbon sink on land, the results are of great importance for all global change studies.

Download or read book Measurements Indicators and Research Methods for Sustainability written by Ian Spellerberg and published by Berkshire Publishing Group. This book was released on 2012-04-09 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements, Indicators, and Research Methods for Sustainability presents a thorough and accessible overview of the ways in which sustainability is charted worldwide. Some articles introduce basic concepts, such as quantitative versus qualitative data or the weak versus strong sustainability debate; others examine how indicators in specific areas (climate change and soil conservation, agriculture, and mining) have been applied (or not) to different regions. Research analysts explain the modes and media through which these measurements are broadcast, stressing the importance of developing methods that can be understood by both experts and ordinary citizens. They also examine the process of monitoring, itself a controversial topic affecting national or international policy, law, rules, and regulations.

Download or read book Dendroclimatology written by Malcolm K. Hughes and published by Springer Science & Business Media. This book was released on 2010-10-28 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: A top priority in climate research is obtaining broad-extent and long-term data to support analyses of historical patterns and trends, and for model development and evaluation. Along with directly measured climate data from the present and recent past, it is important to obtain estimates of long past climate variations spanning multiple centuries and millennia. These longer time perspectives are needed for assessing the unusualness of recent climate changes, as well as for providing insight on the range, variation and overall dynamics of the climate system over time spans exceeding available records from instruments, such as rain gauges and thermometers. Tree rings have become increasingly valuable in providing this long-term information because extensive data networks have been developed in temperate and boreal zones of the Earth, and quantitative methods for analyzing these data have advanced. Tree rings are among the most useful paleoclimate information sources available because they provide a high degree of chronological accuracy, high replication, and extensive spatial coverage spanning recent centuries. With the expansion and extension of tree-ring data and analytical capacity new climatic insights from tree rings are being used in a variety of applications, including for interpretation of past changes in ecosystems and human societies. This volume presents an overview of the current state of dendroclimatology, its contributions over the last 30 years, and its future potential. The material included is useful not only to those who generate tree-ring records of past climate-dendroclimatologists, but also to users of their results-climatologists, hydrologists, ecologists and archeologists. ‘With the pressing climatic questions of the 21st century demanding a deeper understanding of the climate system and our impact upon it, this thoughtful volume comes at critical moment. It will be of fundamental importance in not only guiding researchers, but in educating scientists and the interested lay person on the both incredible power and potential pitfalls of reconstructing climate using tree-ring analysis.’, Glen M. MacDonald, UCLA Institute of the Environment, CA, USA ‘This is an up-to-date treatment of all branches of tree-ring science, by the world’s experts in the field, reminding us that tree rings are the most important source of proxy data on climate change. Should be read by all budding dendrochronology scientists.’, Alan Robock, Rutgers University, NJ, USA

This book was released on 2011-09-18 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the reader with the comprehensive view necessary to understand and critically evaluate the design, implementation, and monitoring of phytoremediation at sites characterized by contaminated groundwater. Part I presents the historical foundation of the interaction between plants and groundwater, introduces fundamental groundwater concepts for plant physiologists, and introduces basic plant physiology for hydrogeologists. Part II presents information on how to assess, design, implement, and monitor phytoremediation projects for hydrologic control. Part III presents how plants take up and detoxify a wide range of organic xenobiotics in contaminated groundwater systems, and provides various approaches on how this can be assessed and monitored. Throughout, concepts are emphasized with numerous case studies, illustrations and pertinent literature citations.
