Production from tropical agricultural systems will need to increase to satisfy the rising food demand of an increasing population coupled with changes in consumption patterns.
These proceedings of a workshop of the International Association for Phytoplankton Taxonomy and Ecology are directed specifically at the relationship between phytoplankton ecology and the trophic status of water bodies.
Multiphase systems dominate nearly every area of science and technology, and the method of volume averaging provides a rigorous foundation for the analysis of these systems.
This book provides an up-to-date synthesis of the understanding of the interaction between the emission of nitrogen, its deposition and impact on the most important components of natural and semi-natural ecosystems.
Most branches of science have what might be termed a 'core area' which is both related to and helps to integrate peripheral topics to form the overall subject area.
The Ecological Bases for Lake and Reservoir Management provides a state-of-the-art review of the range of ecologically-based techniques necessary for the holistic management of lakes and their catchments.
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.
The book is a new compendium in which leading termite scientists review the advances of the last 30 years in our understanding of phylogeny, fossil records, relationships with cockroaches, social evolution, nesting, behaviour, mutualisms with archaea, protists, bacteria and fungi, nutrition, energy metabolism,population and community ecology, soil conditioning, greenhouse gas production and pest status.
The importance of mycorrhiza for the improvement of plant growth is increasingly being realised in Agriculture and Forestry and several mycorrhizal fungi have been commercially recognised for the purpose.
Food problems - the efficient production or procurement of food and its appropriate distribution among members of society - are problems endemic to mankind.
Integrated studies on the assessment and improvement of soil and water quality have to deal almost inevitably with issues of scale, since the spatial support of measurements, the model calculations and the presentation of results usually vary.
Risk Management and the Environment: Agriculture in Perspective is a modern academic work that seeks to bring out both to the private and the policy sectors the importance of risk management in relation to the envi- ronment in agriculture, as the world moves towards freer markets.
These papers include two lectures which address the role of Plant Nutrition in the sustainability of agro-ecosystems and the production of enough high quality food to feed the growing world population.
The world-wide shortage of plant production menacing the survival of many people demands for more and better research, particularly on how to increase food and where it is most needed.
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.
Soil organic matter is a reservoir for plant nutrients, provides water-holding capacity, stabilizes soil structure against compaction and erosion, and thus determines soil productivity.
This proceedings volume includes selected papers presented at the international symposium `Live Food Organisms in Marine Larviculture' held in Nagasaki, Japan, September 1-4 1996.
The chapters in this book were developed from some of the lectures presented at a sym- posium at the XX International Congress of Entomology held in Florence, Italy in August 1996.
About 20 years ago the emphasis in soil chemistry research switched from studies of problems related to scarcities of plant nutrients to those arising from soil pollutants.
The purpose of our present work is to review the fundamental studies on inhibition of soil urease activity and the applied studies on improving efficiency of urea fertilizers by inhibition of soil urease activity.
This book follows upon earlier work which culminated in the publication of two recent books, Sustainable Development: Science, Ethics, and Public Policy (John Lemons and Donald A.
The production of doubled haploids has become a necessary tool in advanced plant breeding institutes and commercial companies for breeding many crop species.
This book is highly recommended on the basis of the following points: - The editors are highly regarded in the field of mycorrhizal biology and one is co-author of the most comprehensive textbook on mycorrhizas; - Chapters by international experts based on invited presentations at the 3rd International Conference on Mycorrhizas, supplemented by invited chapters on special topics; - Mycorrhizas are being increasingly recognised as ubiquitous plant/fungal symbioses, with the potential to influence the function and ecology of around 90% of all land plants; perhaps the most common and also ancient terrestrial symbioses in existence; - This book has a broad coverage of biology of symbioses between mycorrhizal fungi and plants, especially ecto- and arbuscular mycorrhizas (other recent texts have focused mainly on arbuscular mycorrhizal symbioses); - Forward-looking review chapters by keynote speakers including an overview of research challenges for the future; - Up-to-date research focus; - Coverage includes: molecular diversity and detection of mycorrhizal fungi; cellular and molecular interactions between the symbionts; physiology of the interactions; implications of the symbioses for ecosystem processes, including agriculture; - Several complementary chapters on some topics, ensuring that different perspectives are presented (recent edited volumes have had a smaller group of authors and hence narrower focus); - Readership from advanced undergraduate students in biology (particularly plant science), postgraduate students and researchers in universities and government agencies.
In spite of many years of intensive study, our current abilities to quantify and predict contaminant migration in natural geological formations remain severely limited.
The first Symposium on Recent Advances in Problems of Flow and Transport in Porous Media was held in Marrakech in June '96 and has provided a focus for the utilization of computer methods for solving the many complex problems encountered in the field of solute transport in porous media.
