Available in PDF, EPUB and Kindle. Book excerpt: The idea for this book arose in 1993, after the Free State of Bavaria through its Bayrisches Staatsministerium rur Landesentwicklung und Umweltfragen (Bavarian Ministry of Regional Development and the Environment) decided to discontinue both the Bavarian project management (PBWU) for forest decline research and the multidisciplinary field research on the Wank Mountain in the Alps near Garmisch. Forest decline through the action of ozone and other photooxidants was a main topic of the supported re search in the Alps and will be a topic of new investigations in the Bavarian Forest. Many interesting results were obtained, but the researchers involved have not had sufficient time to allow reliable conclusions to be drawn. It was therefore decided to ask inter national experts for contributions in order to summarize the best available evidence of a possible link between ozone and forest decline - a topic which has been studied in the USA since the late 1950s and in Europe since the early 1980s. The original idea of Waldsterben as an irreversible large-scale dieback of forests in Germany was soon recognized to be wrong (Forschungsbeirat 1989). However, the new criteria used for the official German and European damage inventories (loss or yel lowing of needles or leaves, tree morphology) indicate that per sistently high percentages of damaged spruce and pine remain, and there is an increasing percentage of damaged beech and oak, with a high proportion of biotic disease (Forschungsbeirat 1989; UN-ECE 1995).

This book was released on 2013-04-18 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book is summarized those management principles that should be valid in areas where forests continuously are used for production, where biodiversity aspects are important as well as economy and productivity, and where demands on soil status and water quality are set. Especially the very long-term aspects are emphasized, and it is shown how system model thinking is used to reach the goals. Biogeochemical aspects are put forward as they are very important in areas on poor bedrock with acid soils. Forest vitality and stress on trees are treated, as well as the importance of wildlife and their effects of browsing. The balance between social and recreational demands from the society and the economical needs of the landowner is of great concern. Experiences from a special area in South Sweden are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Annual Plant Reviews, Volume 23 A much clearer picture is now emerging of the fine structure of the plant cuticle and its surface, the composition of cuticular waxes and the biosynthetic pathways leading to them. Studies assessing the impact of UV radiation on plant life have emphasized the role of the cuticle and underlying epidermis as optical filters for solar radiation. The field concerned with the diffusive transport of lipophilic organic non-electrolytes across the plant cuticle has reached a state of maturity. A new paradigm has recently been proposed for the diffusion of polar compounds and water across the cuticle. In the context of plant ecophysiology, cuticular transpiration can now be placed in the perspective of whole-leaf water relations. New and unexpected roles have been assigned to the cuticle in plant development and pollen-stigma interactions. Finally, much progress has been made in understanding the cuticle as a specific and extraordinary substrate for the interactions of the plant with microorganisms, fungi and insects. This volume details the major developments of recent years in this important interdisciplinary area. It is directed at researchers and professionals in plant biochemistry, plant physiology, plant ecology, phytopathology and environmental microbiology, in both the academic and industrial sectors.

Download or read book Gaseous Air Pollutants and Plant Metabolism written by M. J. Kozioł and published by Butterworth-Heinemann. This book was released on 2016-03-05 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gaseous Air Pollutants and Plant Metabolism mainly talks about plants and air pollution. The publication of this book is inspired by a symposium on plants and pollution, which generated great interest among the personnel related to the field. The book begins with a brief background on air pollution and continues with a discussion on different types, effects, and solutions to the pollution. The book also features studies about the gaseous air pollution in North America, China, and Japan. The chapters that follow explore the different effects of pollution on chloroplasts, respiration, biochemistry, plant, and plant cells. The text is a valuable reference to undergraduates or postgraduates of chemistry and its related studies.
