Soil Ecology in Sustainable Agricultural Systems (Advances in Agroecology)

By better understanding the complex codependent relationships between soils, soil organisms, and crops, scientists can better predict how an agricultural system will behave when the use of tillage, pesticides, and fertilizers is reduced. Soil Ecology in Sustainable Agricultural Systems demonstrates the considerable potential for the application of soil biological knowledge to the sound management of agroecosystems. Chapters 1-6 cover basic studies, with some focusing on the dual nature of roots and soil organic matter as sinks and sources of carbon and nutrients. Other studies focus on the effects of structure-following and structure-forming soil organisms on biochemical and biophysical processes. Chapter 7 takes a more holistic approach and ties basic knowledge together at the agroecosystem level and discusses developing biological management practices that optimize soil properties for sustained agricultural use.

Waste Management

In this volume the authors offer a comprehensive treatment of all aspects of waste disposal and management. They illustrate these aspects using numerous practical examples. They have included a comparison of regulations in the United States, Canada and Japan, as well as a review of United States environmental legislation - both Federal and State - and a variety of case studies such as Recycling Hawaii and barge wastes.

Quantitative methods in landscape ecology.

Landscape ecology as a modern interdisciplinary science is making use increasingly of quantitative research techniques adopted from other fields. So far, no synthetic reference has been available to those wishing to acquaint themselves with new approaches to quantitative analysis of spatial heterogeneity at the landcape level. This book seeks to meet this need by providing a conceptual framework and illustrating potential applications for methods such as pattern analysis, spatial statistics, fractals, spatial modeling, broad-scale studies, and extrapolation across scales. Each technique is discussed in sufficient detail to be adaptable to a variety of research problems. Quantitative Methods in Landscape Ecology is an important resource for researchers and students of landscape and ecosystem ecology in understanding and analyzing the dynamics of complex spatial systems.

River Quality. Dynamics and Restoration.

What is involved in restoring a river? River Quality: Dynamics and Restoration answers this question through a series of articles and case studies written by some of the field's leading researchers and practitioners. The first part of the book covers the physical, chemical, and biological dynamics of a river system. The second part describes monitoring programs and remedial measures used to restore river systems back to healthy and functional states. The Willamette River in Oregon and the Vistula River in Poland are used to illustrate the dynamic and restoration processes. Each river is in a different stage of restoration and is subjected to different degrees of stress from agriculture, industry, and urbanization. The Willamette is an internationally cited example of a restored river, while the Vistula is a river that has just recently begun the restoration process. Contrasts and comparisons of the two river systems enable readers to learn the limitations of restoration processes and what is involved in the different stages of restoration.

Ecosystem Management: Selected Readings

Forest Decline and Ozone: A Comparison of Controlled Chamber and Field Experiments (Ecological Studies Book 127)

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.

Crassulacean Acid Metabolism: Biochemistry, Ecophysiology and Evolution: 114 (Ecological Studies)

Crassulacean acid metabolism (CAM) represents one of the best-studied metabolic examples of an ecological adaptation to environmental stress. Well over 5 % of all vascular plant species engage in this water-conserving photosynthetic pathway. Intensified research activities over the last 10 years have led to major advances in understanding the biology of CAM plants. New areas of research reviewed in detail in this book include regulation of gene expression and the molecular basis of CAM, the ecophysiology of CAM plants from tropical environments, the productivity of agronomically important cacti and agaves, the ecophysiology of CAM in submerged aquatic plants, and the taxonomic diversity and evolutionary origins of CAM.

Climate Change and Rice

Among basic human needs, food is foremost. Finding sufficient, affordable food is still the major concern of one in every five persons on earth. Rice is the basic staple for more than half of the world - and will continue to be well into the future. For this reason, the Interna­ tional Rice Research Institute (IRRI) has set the goal of improving the well-being of present and future generations of rice farmers and consumers, particularly those with low incomes. As we look toward the 21st century, several important issues cloud food security. World population is growing by almost 100 million people per year, and it is not likely to plateau before the end of the next century. This means that food demand will at least double, and may quadruple. The technologies of the Green Revolution have provided an unprecedented leap in annual rice production, enough to feed 600 million more people, but have had unforeseen social and environmental costs. Loss of genetic diversity and misuse of pesti­ cides endanger the sustainability of the Green Revolution.

Mediterranean-Type Ecosystems: The Function of Biodiversity

Air Pollution Dimensions, Trends and Interactions with a Forest Ecosystem

In the early 1980s, forest decline became a matter of public and scientific concern when forest stands with Norway spruce (Picea abies [L. ] Karst. ) showed evident damage on a large geographical scale throughout Europe. The causes of the observed symptoms could not be elucidated on the basis of the state of knowledge at that time. Therefore, several research projects were launched both in Germany and in some other countries in order to identify the relevant pathogenic factors. In 1985, the Federal Ministry for Research and Technology decided to include the site "Postturm", forest district Farchau/Ratzeburg, in the spon­ sorship of the research on forest decline as a site typical for lowlands and a sphere of anthropogenic urban influence. The investigation area is situated about 40 krn east-northeast of the city of Hamburg.

Peatland Forestry: Ecology and Principles (Ecological Studies)

Peatlands (or mires) cover at least 550 million ha globally, of which the greater part is situated between 50° and 70° N. Although the majority of peatlands are not used for human needs, there are large areas where agriculture, peat or wood production has been practiced. The suitability of peatlands for forestry differs from country to country depending on climatic conditions, raw wood demand, silvicultural management practice and tradition, as weH as the infrastructure in the remote areas considered.

High-latitude rainforests and associated ecosystems of the West Coast of the Americas.

Regional intercomparisons between ecosystems on different continents can be a powerful tool to better understand the ways in which ecosystems respond to global change. Large areas are often needed to characterize the causal mechanisms governing interactions between ecozones and their environments. Factors such as weather and climate patterns, land-ocean and land-atmosphere interactions all play important roles. As a result of the strong physical north-south symmetry between the western coasts of North and South America, the similarities in climate, coastal oceanography and physiography between these two regions have been extensively documented. High Latitude Rain Forests and Associated Ecosystems of the West Coast of the Americas presents current research on West Coast forest and river ecology, and compares ecosystems of the Pacific Northwest with those of South America.

Statistical methods for environmental agricultural sciences. Second Edition

The first edition of this book, popular around the world, is surpassed only by this new Second Edition. Improvements such as new and revised exercises, a broad range of practical and relevant case studies, and expanded theoretical concepts make this even better for users of statistics. The book emphasizes the practical application of statistics and provides examples in various fields of environmental and agriculture sciences. Because it uses simple, non-mathematical language to present statistical techniques, the reader requires only a familiarity with elementary algebra and mathematical notations to understand and apply the concepts described. This logically organized book covers the following topics: Part 1 introduces statistical concepts as they apply to different fields of environmental and agriculture sciences and provides descriptive measures of central tendency and variability; Part 2 covers probability and sampling concepts used in inferential statistics; Part 3 presents parametric methods in hypothesis testing, which include research designs; Part 4 discusses a number of nonparametric techniques; Part 5 explains tests of association and prediction; and lastly, analysis of change over time is detailed in Part 6. The appendices contain statistical tables for reference purposes.

Sediments and toxic substances.

In modern sediment research on contaminants five aspects are discussed which, in an overlapping succession, also reflect develop­ ment of knowledge on particle-associated pollutants during the past twenty-five years: (1) identification of sources and their distribution; (2) evaluation of solid/solution relations; (3) study of transfer mecha­ nisms to biological systems; (4) assessment of environment impact; and (5) selection and further development of remedial measures, in par­ ticular, of dredged materials. Scientific research and practical develop­ ment are still expanding in all these individual aspects. Similar to other waste materials, management of contaminated sed­ iments requires a holistic approach.

Observation of the Earth and Its Environment

The following listing represents a survey and a short description of 'Earth Observing Mis­ sions' in alphabetical order. The listing in Part A considers completed-, operational-as well as planned missions on an international scale (Earth observations from space know no na­ tional boundaries). A look into past activities is important for reasons of heritage, context and of perspective. The document is intended for all who want to keep track of missions and sensors in the fast -growing field of Earth observations. There cannot be any claim to com­ pleteness, although a considerable effort was made to collect and integrate all known mis­ sions and sensors into this book.
