Book excerpt: Growth is the biological phenomenon of increase in size with time. The sudden increase in tree diameter often observed after rain is not due to growth but reflects the effects of bark swell. The relationships of tree size to age and increment to age are also important to the forester particularly in predicting future growth. In any one growing season, different parts of a tree start growing at different times. Different species may also react differently. Generally, height growth precedes any diameter growth or needle flush. The progression of terminal bud extension (main stem and branches) is basipetally, i.e. extension growth starts at the top of the tree and progressively moves downwards towards the base. The amount of height growth in any one season depends on hereditary factors, immediate past environmental conditions and present environmental conditions. Diameter growth also proceeds basipetally and is much more related to current foliage and present environmental conditions. The book presents the most up-to-date research in the field.

Download or read book Causes and Consequences of Forest Growth Trends in Europe written by Hans-Peter Kahle and published by BRILL. This book was released on 2008-05-31 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest growth in Europe has been increasing during the last decades. The possible causes suggested to explain this have been increasing atmospheric carbon dioxide concentration, improved temperature and precipitation climate, increasing nitrogen deposition and better management. In this book complementary approaches are used to discriminate between the importance of each of these factors. Investigations over large geographical areas are used to separate current variability while detailed studies of the growth of individual trees allow historical trends to be evaluated. Four different mechanistic forest ecosystem models supplement the empirical investigations. The major cause of the observed growth increase is attributed to the increased nitrogen availability. In future, direct temperature effects and increasing atmospheric carbon dioxide concentration are likely to become important determinants of forest growth. Anyone interested in the future of production and health of Europe's forests should benefit form this extensive analysis of the current status and projections of forest growth.

This book was released on 2006-04-11 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: year simulations in order to separate noise in the system from the climate change signal. Several contributing papers focused on case studies using Regional Climate Models (RCMs) linked to hydrological models, applied to the analysis of runoff under conditions of convective activity and extreme precipitation, in regions of complex topography, or stakeholder-driven investigations such as water runoff simulations in Quebec undertaken for a major utility. Thorough analyses of GCM results for the Century were reported at the Workshop, in order to illustrate the improvements in model results which have taken place in recent years, and the increasing confidence with which the models can be used for projecting climatic change in coming decades. However, there is still much room for improvement; there is also a need to address more fully the manner in which climate and impacts models (e. g. , hydrological models) can be linked, in terms of consistency and the overlap between different scales, the underlying physical assumptions, and the parameterizations used. Session 2 was devoted to the two extremes of water resources, namely floods and droughts, the focus here being to identify the climate change component in river floods. These have significant economic implications, as was shown by several scientists from Western and Central Europe. Many long time series have been studied worldwide with the aim of detection of nonstationarities, yet there is no conclusive evidence of climate-related changes in flow records, in general.

Download or read book Impact of Air Pollutants on Southern Pine Forests written by Susan Fox and published by Springer Science & Business Media. 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.
Download or read book Resource Physiology of Conifers written by William K. Smith and published by Academic Press. This book was released on 2013-10-22 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coniferous forests are among the most important of ecosystems. These forests are widespread and influence both the financial and biological health of our globe. This book focuses attention on conifers and how these trees acquire, allocate, and utilize the resources that sustain this crucial productivity. An international team of experts has surveyed and synthesized information from an expanding area of inquiry. The first half of the book describes how resources are acquired both by means of photosynthesis and through root systems. The latter half of the volume focuses upon how resources are stored and used. As conifers continue as a resource and ever increasingly important contributor to the regional and global environmental sustainability, this book will help establish how much sustainability can be expected and maintained.
