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 2013-06-29 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The threats posed by air pollution and climate change have resulted in considerable public debate about forest condition and growth during the past two decades. Despite the massive input ofresearch resources, no clear answers have been found to these global questions. Although there have been substantial advances in our knowledge of the effects of air pollutants on the forests, many of the questions associated with forest condition are still open. Monitoring of forest condition at the national level started in Finland in 1985 in accordance with the methodology drawn up by the International Co-operative Programme on Assessments and Monitoring of Air Pollution Effects on Forests (ICP Forests, UN/ECE). Since then, research into forest condition and vitality has been one of the key areas in the research carried out by the Finnish Forest Research Institute. Three basic questions formed the starting point for the multidisciplinary, Forest Condition Research Programme: What changes are taking place in our forests? Why does forest condition vary, and why do trees appear to be suffering? How can forest condition be maintained through appropriate forest management? This report covers forest condition and changes in environmental factors on the of the latest findings, publications and expertise of researchers participated in basis the Forest Condition Research Programme. In addition to researchers from the Finnish Forest Research Institute, a large number of scientists from domestic and foreign universities and research institutes also made a considerable contribution to the research programme.

Available in PDF, EPUB and Kindle. Book excerpt: Human activities impact the environment and modify the cycles of important elements such as carbon and nitrogen from local to global scales. In order to maintain long-term and sustainable use of the world's natural resources it is important that we understand how and why ecosystems respond to such changes. This book explains the structure and functioning of terrestrial ecosystems, using examples ranging from the Arctic to the tropics to demonstrate how they react under differing conditions. This knowledge is developed into a set of principles that can be used as starting points for analysing questions about ecosystem behaviour. Ecosystem dynamics are also considered, illustrating how ecosystems develop and change over a range of temporal and spatial scales and how they react to perturbations, whether natural or man-made. Throughout the book, descriptive studies are merged with simple mathematical models to reinforce the concepts discussed and aid the development of predictive tools.

This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, forest decline has become increasingly apparent. The decline in forest health was often reported to be associated with air pollution. The present study on Norway spruce stands in the Fichtelgebirge analyses various processes interacting within forest ecosystems. It covers transport and deposition of air pollutants, the direct effects of pollutants on above-ground plant parts, the responses of soil to acid rain, and the changing nutrient availability, and the accompanying effects on plant metabolism and growth. The role of fungi, microorganisms and soil animals in the decline of these stands is also assessed. The volume is concluded with a synthesis evaluation of the influence of different factors, and their interactions on forest decline.

This book was released on 1992 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the recent decline of red spruce and the role of acid rain and associated air pollutants in this decline. The purpose of the book is to summarize a large body of recent research on this important environmental issue. The book is divided into 3 sections: Section I summarizes the features of spruce-fir forests in the Eastern U. S. and examines the ecology of the forests, their soils, and the atmospheric conditions experienced by these forests. Section II looks at experimental results from many air pollution studies and evaluates mechanisms of air pollution effects on red spruce trees. Section III synthesizes the current state of knowledge regarding the widespread red spruce decline in forests of the eastern United States.
