Available in PDF, EPUB and Kindle. Book excerpt: Malure grafts of five clones of Sitka spruce were exposed to simulated acid mist (equimolar mixtures of sulphuric acid and ammonium nitrate) at pH2 .5 and5 .0 in open-top chambers between May a nd November. The treatments were applied four times a week on consecutive days giving an overall dose similar to wet and occult deposition in some areas of upland Britain. One of the clones tested (DF) was the clone used in the mature tree experiment at the Glencorse field site. Measurement of frost hardiness, leaf surface characteristics and visible Injury w ere made. Acid mist, (pH2 .5) significantly reduced frost hardiness of four out of the five clones and the reduction was of the same order of magnitude as measured in 1990 for open-pollinated seedlings of Sitka spruce. A significant effect of acid mist treatment on frost hardiness was not f ound for clone DF. Clones varied in their frost sensitivity clo ne DF being particularty frost sensitive and it was generally found that the more sensi ...

This book was released on 2012-12-06 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest decline became a matter of public and scientific concern in France in 1983 when conifers in the Vosges mountains were found to exhibit unusual crown deterioration. An impassioned controversy on a supposedly large scale forest health problem was then in full swing in Central Europe. A co-ordinated research programme entitled DEFORPA ("Deperissement des For~ts et Pollution AtmospMrique") was launched in 1984. This programme ran from 1984 to 1991 and a number of projects are still in progress. The Programme was sponsored by three French ministries (Enviroument, Agriculture and Forestry, Research and Technologyl), several state agencies, various regional authorities and the Commission of the European Communities (DO xn and DG VI). Initially, emphasis was solely laid on the understanding of forest decline in the mountainous areas - because damage was most obvious there - in relation to natural and man-made factors. Air pollution was given high but not overwhelming priority. Thus, the DEFORPA Programme was not in its essence a nation-wide assessment of air pollution effects, unlike a number of national acidification research programmes in Europe and North America. During. the programme, however, the areas of concern expanded. In particular, research into water acidification in the Vosges mountains was developed in parallel with the DEFORPA Programme, and possible eutrophication of the ground flora in northeastern France became the subject of new research.

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 Green Accounting in Europe Four case studies written by Anil Markandya and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional economic accounts, which measure Gross National Product (GNP)and related indicators of national performance, do not fully allow for the damages caused to the environment in the course of producing and consuming goods and services. Nor do they fully account for the fact that some resources are being depleted in achieving the living standards that we enjoy today. This failure is important, because policy-makers are guided by the changes in macroeconomic indicators such as GNP. Moreover such indicators are not a good guide to the sustainability of present practices of consumption and production. This book provides practical estimates of one key area of neglect in the present national accounts - the measurement of environmental damages. The book sets out the methodology for making such estimates and then applies it to data from four countries: Germany, Italy, The Netherlands and the UK. The results show what can be achieved in the way of consistent damage estimates and what the key problems are.
Download or read book Protocols in Lichenology written by Ilse Kranner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: As an intricate association between a fungus and one or more green algae or cyanobacteria, lichens are one of the most successful examples of symbiosis. These fascinating organisms survive extreme desiccation and temperatures. They are adapted to a great variety of habitats, from deserts to intertidal zones, from tropical rain forests to the peaks of the Himalayas and to circumpolar ecosystems. Lichens are extremely efficient accumulators of atmospherically deposited pollutants, and are therefore widely used to monitor environmental pollution. Their wide range of secondary products show pharmaceutically interesting fungicidal, antibacterial and antiviral properties. Lichens are extremely difficult to culture. This manual provides well-tested tissue culture protocols, protocols for studying lichen ultrastructure, (eco)physiology, primary and secondary compounds, and for using lichens as bioindicators.

Available in PDF, EPUB and Kindle. Book excerpt: An international workshop on `CO2 and Biosphere' was held in Wageningen, the Netherlands on 15-19 November 1991 as part of the activities of the CO2 Commission of the Netherlands Organization for Scientific Research: this volume includes 32 papers presented at the workshop. The CO2 Commission stimulates and coordinates a broad range of research projects related to the greenhouse effect. This is reflected in the scope of papers presented, ranging from detailed analyses of ecological and physiological effects of atmospheric CO2 enrichment to biosphere-atmosphere aspects, such as regional evaporation, energy balance and ecosystem responses. Relevant directions for future research are indicated by presentations on carbon fluxes in the soil, secondary plant metabolism and plant-insect interactions.

Download or read book Environment written by Jules Pretty and published by SAGE. This book was released on 2006-06-23 with total page 1588 pages. Available in PDF, EPUB and Kindle. Book excerpt: This four-volume set explores the locations where the environment matters most such as where people are poor, where environments are under threat (such as on frontiers), where there are few natural resources remaining, and where industrialization is rampant. It will also explore these concerns at different system levels, from local-community, to regional, national and global. It will also explore costs of damage to the very resources on which economies rely, and the values of environmental goods and services and the controversies surrounding such valuations. It is organized around environment-people interactions (livelihoods, poverty, income, economic growth); environment-environment interactions (do people matter?); and people-people interactions (collective action challenges, institutions).
