Plantation Silviculture
ISBN: 9789024733798 / Angielski / Twarda / 322 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Plantations of a wide range of tree species have assumed an important place in our world, providing wood for industry, fuelwood and animal fodder, protection from adverse environments and for the soil, as well as amenity and aesthetically pleasing landscapes. silvicultural knowledge of this particular branch of forestry first developed in Europe more than two centuries ago but in many parts of the world is still in a process of rapid evolution as more and more plantations are established to meet specific needs. The first exotic tree species to be established in plantations in my own country...

World Forests, Society and Environment
ISBN: 9780792353218 / Angielski / Miękka / 404 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book addresses current global and regional issues concerning the world's forests, societies and the environment from an independent and non-governmental point of view. A main message is that cooperation on a global scale is not only commendable, but essential if solutions to the problems facing the world's forests are to be found. To achieve this, modern science needs to find a clearer picture of relationships between forests, human activity and the environment and of the consequences of environmental change for the ability of societies to survive.

Old Growth Urban Forests
ISBN: 9781461405825 / Angielski / Miękka / 92 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Millions of urbanites never see primeval forests during their lives except for the old growth forests found in urban parks. Unfortunately, these forests are on the verge of disappearing because arboreal reproduction is lost to human trampling and park administrators and urban foresters do not maintain these "natural" forests. To aid urban foresters and park managers in meeting the challenges, research on old growth forests in urban parks is synthesized in terms of historical ecology to introduce the methods utilized to reveal long-term forest composition changes. The case study of three...

The Forest Farms of Kandy: And Other Gardens of Complete Design
ISBN: 9780754609582 / Angielski / Twarda / 552 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Throughout the tropical world, especially in South and Southeast Asia, tropical America, Africa and Oceania, there exists a range of forest garden farming systems. These are small, low-input, but productive and sustainable family units of highly diversified trees, palms, bushes and vines, with few conventional field crops or livestock. Providing a survey of these systems around the world and an in-depth analysis of the farms around Kandy, Sri Lanka, this book offers an economic and ecological description and evaluation of this ancient agroforestry system and its relationship to a wide range...

Landscape Boundaries: Consequences for Biotic Diversity and Ecological Flows
ISBN: 9781461276777 / Angielski / Miękka / 452 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The emergence of landscape ecology during the 1980s represents an impor- tant maturation of ecological theory. Once enamored with the conceptual beauty of well-balanced, homogeneous ecosystems, ecologists now assert that much of the essence of ecological systems lies in their lumpiness. Patches with differing properties and behaviors lie strewn across the land- scape, products of the complex interactions of climate, disturbance, and biotic processes. It is the collective behavior of this patchwork of eco- systems that drives pattern and process of the landscape. is not an end point This...

Advances in Soil Science: Volume 15
ISBN: 9781461277682 / Angielski / Miękka / 262 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The study of soils has taken on increased importance because a rapidly expanding population is placing demands on the soil never before experi enced. This has led to an increase in land degradation. Land degradation is one of the most severe problems facing mankind. Volume 11 of Advances in Soil Science was devoted entirely to this critical area of soil science. The editors of that volume, R. Lal and B.A. Stewart, defined soil degradation as the decline in soil quality caused by its misuse by humans. They further stated that soil degradation is a major concern for at least two reasons. First,...

Amazonian Rain Forests: Ecosystem Disturbance and Recovery
ISBN: 9781461291022 / Angielski / Miękka / 133 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. DEVELOPMENT AND DISTURBANCE IN AMAZON FORESTS Contrasting Impressions 6 2 The rain forests of the Amazon Basin cover approximately 5.8 x 10 km (Salati and Vose 1984). Flying over even just part of this basin, one gazes hour after hour upon this seemingly infinite blanket of green. The impression of immen- sity is similar when viewed from the Amazon River itself, or from its tributar- ies. From a hammock on the shaded deck of a riverboat, the immensity of the forest presents an incredible monotony as one view of the shoreline blends unnoticeably into another. From both perspectives, the...

Advances in Soil Science
ISBN: 9781461291121 / Angielski / Miękka / 222 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The world needs for food and fiber continue to increase. Population growth in the developing countries peaked at 2. 4 percent a year in 1965 and has fallen to about 2. I percent. However, in many developing countries almost half the people are under 15 years of age, poised to enter their productive and reproductive years. The challenges to produce enough food for this growing population will remain great. Even more challenging is growing the food in the areas of greatest need. Presently the world has great surpluses of food and fiber in some areas while there are devastating deficiencies in...

Molecular Genetics of the Bacteria-Plant Interaction
ISBN: 9783642693403 / Angielski / Miękka / 396 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. During the last decade it has become clear that bacteria-plant interactions play an important role in agricultural science. In particular, symbiotic nitro gen fixation, plant tumorigenesis, and plant pathogenic bacteria have been extenSively investigated. Therefore, several of my colleagues suggested the importance of organizing a specialized symposium on the "Molecular genetics of the bacteria-plant interaction." This symposium was held in Germany, at the University of Bielefeld, in the autumn of 1982. The International Program Advisory Board, together with the National Organizing Committee,...

ISBN: 9784431679851 / Angielski / Miękka / 332 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Since the late 1960s the Indonesian state of East Kalimantan has witnessed a marked increase in the impact of human activities chiefly commercial logging and agricultural exploitation. Located on the island of Borneo, East Kalimantan also was subjected to prolonged droughts and extensive wildfires in 1982-83 and 1997-98 that were linked to the El Nino-Southern Oscillation (ENSO) phenomenon. The changes in the rainforest ecosystem in East Kalimantan during this 15-year cycle of severe ENSO events are the subject of this book. With an eye toward development of rehabilitation techniques for...

The Reticuloendothelial System in Health and Disease: Functions and Characteristics
ISBN: 9781468432992 / Angielski / Miękka / 495 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. An extraordinary development of the knowledge, concepts and biomedical applications has occurred during the past two decades in the biological sciences, including the Reticuloendothelial Sys- tem (RES). For example, it is now widely recognized that distinct classes of cells are involved in the recognition of "exogenous" invaders of the body such as microorg nisms and other foreign an- tigens, as well as of "endogenous" parasites represented by trans- formed neoplastic cells and altered "self" antigens. Prominent among cell populations involved in such recognition of antigens and subsequent...

Taylor Department of Genetics University of California Berkeley, California 94720 It is evident by now that there is a great deal of interest in exploiting the new technologies to genetically engineer new forms of plants. A purpose of this meeting is to assess the possibilities. The papers that follow are concerned with the analysis of single genes or small gene families. We will read about genes found within the nucleus, plastids, and bacteria which are responsible for agri- culturally important traits. Given that these genes can be isolated by recombinant DNA techniques, there...
