This book focuses on sediments as a pollutant in natural freshwater and marine habitats, and as a vector for the transfer of chemicals such as nutrients and contaminants.
The Bear Brook Watershed in Maine (BBWM) is a long-term, whole-watershed study examining the effects of experimentally elevated N and S deposition on a treated watershed, in comparison to the adjacent reference watershed.
As a member of the working group (WG) on "e;Temperate Zone Fruit Trees in the Tropics and Subtropics"e; of the International Society for Horticulture, I was aware of the lack of readily available information needed in many warm-climate locations where temperate fruit crops are grown.
Due to the long-term planning horizons and the great variety of natural, economic, and operational hazards affecting forest ecosystems, uncertainty and multiple risk are typical aspects of forest management.
Much research has been done recently, and more is now in progress, to increase the effectiveness under tropical conditions of methods which have been developed in Europe for preserving timber.
Planted forests, from irrigated eucalypts in Brazil to Douglas-fir seedlings in the mountains of Oregon, are described and discussed by international experts.
This book tells a story of a large lake affected by agricultural and urban activities that have led to severe eutrophication problems with nuisance blue-green algal blooms.
It was in late 2002 that the idea of preparing a collection of multi-authored chapters on different aspects of ag- st forestry as a compendium for the 1 World Congress of Agroforestry, June 2004, was tossed around.
On the occasion of the 50th Anniversary of the International Association of Wood Anatomists several symposia were held during the 13th International Botanical Congress in Sydney, August 1981.
Woody plants constitute an artificial and heterogeneous group of plants that share some common phenotypic characteristics but otherwise have no strong evolutionary relationships, nor do they share a common habitat.
International climate change policy can be broadly divided into two periods: A first period, where a broad consensus was reached to tackle the risk of global warming in a coordinated global effort, and a second period, where this consensus was finally framed into a concrete policy.
Arising initially from a conference, the papers published here have been integrated into book form to provide information on human activities and the tropical rainforest in the past and present, and on the possible future of the rainforest, in a unique way.
This is the third annual compendium of a Technical Session of the Physiology Working Group of the Society of American Foresters held at the National Convention.
The production of doubled haploids has become a necessary tool in advanced plant breeding institutes and commercial companies for breeding many crop species.
In this book we bring together the most up-to-date information on developments, both basic and applied, that already have or are expected to impact the field of ornamental breeding.
Freer Trade, Sustainability, and the Primary Production Sector in the Southern European Union is the first full-scale academic work to cap- ture the primary production sector policy aspects of trade liberaliza- tion and sustainability with a detailed focus on a typical southern EU country, Greece.
This Special Issue of Water, Air and Soil Pollution offers contributions from the th 18 IUFRO workshop on Air Pollution Stress, Forest Responses to the Pollution st Climate of the 21 Century held in Edinburgh, Scotland, from September 21 to 23,1998.
During the 4th International Consultation on Forest Genetics and Tree Building, held in 1998 in Beijing, China, leading scientists were invited to review past achievements, to redefine the role of forest genetics and breeding in contemporary forestry, and to set priorities for future research and development.
Since the first edition of our book "e;Tissue Culture in Fores- try"e; in 1982 we have witnessed remarkable advances in cell and tissue culture technologies with woody perennials.
Agroforestry research is central to developing methods for the sustainable use of natural renewable resources, evolving to address the needs of the coming century.
Forests represent a remnant wilderness of high recreational value in the densely populated industrial societies, a threatened natural resource in some regions of the world and a renewable reservoir of essential raw materials for the wood processing industry.
It is our conviction that professional skill in forestry will develop more readily and more efficiently if forestry students are presented with a clear understanding of the im- pact of the physical factors that both enhance and inhibit forestry activities.
It is our conviction - based on many years of teaching and practical experience - that professional skill in forestry will develop more rea- dily and more efficiently if forestry students are presented with a clear understanding, at an early stage, of the impact of the physical factors that both enhance and inhibit forestry activities.
This book draws together contributions from forest economists in the Research Triangle of North Carolina, with co-authors from institutions around the world.
When two of us (Jifi Kolbek, Miroslav Sriltek) were working in North Korea on the Czech- Slovak field expeditions of the early 1990s, we did not think initially of comparing our results with the vegetation of surrounding areas or of writing a book.
Policy issues relating to forestry have been the subject of much debate in recent years, and many countries and international agencies have recently, or are currently in the process, of revising their policies for forestry.
