  • The Common Agricultural Policy beyond the MacSharry Reform

    • 1 Edición
    • Volumen 230
    • C. Folmer + 4 más
    • J. Tinbergen
    • Inglés
    The reform of the Common Agricultural Policy (CAP) which is now being implemented, reduces the support for a selected number of agricultural products. This book uses welfare theory and applied general equilibrium analysis to assess the medium to long term consequences of this reform, if the new policies remain in place until the beginning of the next century. It analyses the implications of two alternative scenarios: a) a further trade liberalisation covering all commodities; and b) increased protectionism with high prices, constraints on production and export subsidies (financed by the farmers themselves). The study also investigates the implications of financial renationalisation, whereby the European Union member-states would cover the costs of their own support measures.

    • Inglés
    FROM THE GENERAL PREFACE: This multivolume work, The Mollusca, had its origins in the mid 1960s with the publication of two volumes entitled Physiology of Mollusca and edited by Wilbur and Yonge. In those volumes, 27 authors collaborated to summarize the status of the conventional topics of physiology as well as biochemistry, reproduction and development, and ecology. Within the past two decades, there has been a remarkable burgeoning of molluscan research generally and with it the development of new fields of investigation. During the same period, several excellent books on molluscs have appeared. However, they do not provide adequate information on the many recent advances or give the breadth of perspective of current knowledge of the phylum. Clearly, there was need for a larger work with a comprehensive treatment of major areas of molluscan research. The Mollusca, as a series of 12 volumes, attempts to fulfill this objective. Even here, practical considerations have meant that certain aspects of molluscan research have not been included.Each major area is treated by several authors, each reviewing his or her special field. The areas are structure and function, metabolic biochemistry, molecular biomechanics, environmental biochemistry, physiology, ecology, reproduction and development, neurobiology and behavior, and evolution. Throughout, the authors have given emphasis to recent advances and present status of molluscan biology. In so doing, directions of future research have become evident.The Mollusca is intended to serve several disciplines--zoology... biochemistry, physiology, and paleontology. It will prove useful to researchers and to all others with interests in molluscs.FROM THE PREFACE TO VOLUME 10: Recent events that have stimulated a great surge of investigation into the evolution of the Mollusca include the discovery of well-preserved microscopic molluscs at most levels of the Cambrian on five continents, the development of electron microscopy, the need to examine competing models of the early history of the phylum, new interest in interstitial fauna of littoral and near-littoral sands, and significant advances in our knowledge of shell ontogeny, construction, and evolution. It is timely that an up-to-date synthesis involving both paleontologists and zoologists should be published after a decade of such activity and advance when many of the long-held views on molluscan phylogeny have been overturned.This book deals with all molluscan classes except the Cephalopoda, which will be treated in Volume 12. The two books together provide an up-to-date introduction to the evolution of the Mollusca with adequate references to guide further work. They will be invaluable to specialists on molluscs, postgraduate research workers, and undergraduates with particular interests in this phylum. Authorities on the various molluscan groups were asked to express their views and to treat the subject as they wished; the book provides a valuable record of their opinions at this time.While the main groups are broadly and fully treated, focus has been narrowed toward a few selected minor groups of particular interest such as limpets, land snails, and the Anomalodesmata, in which recent work has been particularly significant.Because recent years have seen major revisions in classificatory terms, the editors have provided an outline classification into which the chapter topics fit.

  • Agriculture, Growth and Redistribution of Income

    Policy Analysis with an Applied General Equilibrium Model in India
    • 1 Edición
    • Volumen 190
    • N.S.S. Narayana + 2 más
    • J. Tinbergen
    • Inglés
    This book presents an empirically estimated applied general equilibrium model for India and the analysis of a wide range of policy issues carried out using the model. The various chapters in the book deal with public distribution policies, foreign trade and aid policies, rural works programmes, terms of trade policies, fertilizer subsidy policies and irrigation development policies. These policies are analysed in terms of their immediate and medium term effects on production, consumption and prices of different commodities, on the growth of the economy as well as on the distribution of income among different groups in rural and urban areas and the incidence of poverty in the economy. Each chapter dealing with policy analysis describes the analytical issues involved, the historical context and experience of the policy concerned, results of the model scenarios and the policy insights that emerge.

  • Diversity of Environmental Biogeochemistry

    • 1 Edición
    • Volumen 6
    • J. Berthelin
    • W.S. Fyfe
    • Inglés
    Biogeochemistry, still in its formative stage twenty years ago, is now a young, interdisciplinary subfield of earth sciences, life sciences and chemistry. An international scientific association (International Symposia on Environmental Biogeochemistry incorporated - ISEB) was founded to organize international symposia to bring together microbiologists, biologists, chemists, geochemists, soil scientists, oceanographers, ecologists and environmental engineers interested in the biogeochemistry of terrestrial, aquatic and atmospheric environments.After the 8th ISEB held in Nancy, France, this volume was compiled. These fifty selected contributions from specialists of varying backgrounds and interests show the diversity and the common framework of the direct or indirect interactions of living organisms and their abiotic environments.

  • Comprehensive Insect Physiology, Volume 4

    Regulation: Digestion, Nutrition, Excretion
    • 1 Edición
    • G. A. Kerkut
    • Inglés
    In this volume, seven of the chapters deal with feeding and diet, which is reasonable since insects consume an estimated l5-20% of all the world's planted crops. Many insects even have a specialized larval feeding stage that usually occupies a different ecological niche to the adult and so does not compete for the adult's food stock. Other chapters describe the means by which insects maintain their water balance, nitrogen balance and temperature balance under a range of conditions. These involve regulation by hormonal and behavioural systems that are also described here. The l4 chapters are all extensively illustrated and referenced and therefore provide excellent summaries of current knowledge. They will be of great value to entomologists, zoologists and biologists in general.

    • Inglés
    When the first edition of this book appeared in 1978, it was warmly received. Most readers and reviewers especially valued the extensive coverage of the literature in the chapters dealing with the different crops. ``... a valuable and timely addition to plant breeders and of outstanding value to breeders of ornamental plants. The book's special strength resides in the extensive review of literature ...'' (International Journal for Breeding Research). This is also reflected by the many times that the work has been referred to in other publications.This new edition provides plant breeders as well as scientists with an up-to-date overview of methods and results of the application of mutation breeding in order to genetically improve vegetatively propagated crops. General principles and background information about mutation breeding in general, methods of treatment, material to be treated and results are discussed in the introductory chapters, followed by a description of the specific situation in each of the vegetatively propagated crops ever used in a mutation breeding project.This volume brings together all the important and relevant literature in the field. It provides a complete account of mutation breeding of vegetatively produced crops, presenting conclusions about the value of the method, its possibilities, limitations and shortcomings and the possible difficulties of further application in various crops. The initial chapters deal with the interactions between mutagenic treatment and plant material, such as aspects of mutagenic treatment, post-irradiation behaviour of shoot apices and adventitious bud techniques. All available literature is then discussed crop by crop and critically evaluated. Almost 1700 references are covered and whenever possible suggestions for more efficient application of mutation breeding methods are given.

  • Photosynthetic Reaction Center

    • 1 Edición
    • Volumen 2
    • Johann Deisenhofer + 1 más
    • Inglés
    The availability of the photosynthetic reaction center's structure at an atomic resolution of less than three angstroms has revolutionized research. This protein is the first integral membrane protein whose structure has been determined with such precision. Each volume of the Photosynthetic Reaction Center contains original research, methods, and reviews. Together, these volumes cover our current understanding of how photosynthesis converts light energy into stored chemical energy.Volume II details the electron transfer process; it is oriented to the physical aspects of photosynthesis. It thus primarily discusses bacterial photosynthesis and model compounds. Volume II features the very complex and rapidly evolving issues associated with the theory of electron transfer in the bacterial reaction center, and explores picosecond and femtosecond spectroscopy. This volume also covers holeburning spectroscopy; primary events of bacterial photosynthesis with emphasis on the application of large, external electric fields designed to manipulate and probe mechanisms of the initial chemistry; the role of accessory carotenoid pigments; the techniques of infrared spectroscopy and magnetic resonance as applied to photosynthesis; and the interplay between natural and artificial photosynthesis.

  • Soil Structure/Soil Biota Interrelationships

    International Workshop on Methods of Research on Soil Structure/Soil Biota Interrelationships, Held at the International Agricultural Centre, Wageningen, The Netherlands, 24-28 November 1991
    • 1 Edición
    • L. Brussaard + 1 más
    • Inglés
    Some pioneers in soil research such as Müller and Kubiëna were as much biologists as they were soil scientists and the legendary biologist Charles Darwin was foresighted in recognizing the earthworms as instrumental in reworking the soil, thereby forming what he called "vegetable mould". Still, soil science has largely been the realm of physicists and chemists over the past decades. Whatever the reason, this picture is rapidly changing. Until recently, research on the transport and transformation of elements in soil was often concerned with either soil biota/plant relationships or with soil structure/plant relationships, if the biota were considered at all, but very few studies explicitly took the interrelationships between soil structure and soil biota into account. The conference on Soil Structure/Soil Biota Interrelationships, held at Wageningen, The Netherlands, 24-28 November 1991, was meant to bridge that gap, focussing on methods of research, organized in three levels: features, processes and effects. The proceedings of the conference are testimony of the need to intertwine the biological, morphological, physical and chemical disciplines in soil research to understand better and forecast soil properties and processes as related to land use for agricultural and other purposes.This book should be of particular interest to soil scientists and ecologists who feel the need for a cross-disciplinary approach in soils research. It should also be a rich source of teaching material for courses in soil science and soil ecology at graduate level and above, with ample reference to studies on land use as related to agriculture and the environment.

  • Differential Growth in Plants

    • 1 Edición
    • Peter W. Barlow
    • Inglés
    Differential Growth in Plants contains the papers presented at Symposia 2.04 ""Spatial and Temporal Patterns of Development"" and 2.14 ""Movements Based on Differential Flank Growth"" at the XIV Botanical Congress held in Berlin during July 1987. Organized into 10 chapters, this book begins by explaining the differential growth in plants. Some chapters follow on the biophysics of differential growth; the phototropic behavior of hypocotyls and coleoptiles in connection with the distribution of indole-3-acetic acid and of growth-inhibiting substances within them; and the differential growth and hormone redistribution in gravireacting maize roots. Other topics explained include plant movements caused by differential growth; genetic analysis of tropic responses; growth and bending of a cylindrical structure in terms of the distribution of relative growth rates; and differential growth resulting in the specification of different types of cellular architecture in root meristems. This book also elucidates the curving and twinning of stems, as well as the spatio-temporal analysis of flower ontogenesis.

  • Comprehensive Insect Physiology, Volume 10

    Biochemistry
    • 1 Edición
    • G. A. Kerkut
    • Inglés
    The underlying theme of this volume is the understanding of the molecules and processes important in the primary metabolism of insects. The 19 chapters provide both rich historical perspectives and timely reviews of current research, as well as showing the extent of progress to be expected in the near future, including the application of advanced techniques now used for the study of microbial and mammalian processes. The major themes of metabolism, proteins and nucleic acids, and biochemical events in the nervous system each have several chapters devoted to them, but specific topics such as pigments, toxins, and aging are also covered in detail. This extensive volume is therefore an invaluable source of information not only for entomologists but also for all scientists whose work involves insect biochemistry, including zoologists, biochemists, and molecular biologists and geneticists.

  • Animal Biotechnology

    Comprehensive Biotechnology, First Supplement
    • 1 Edición
    • L.A. Babiuk + 2 más
    • Inglés
    The advent of biotechnology has the potential to develop a variety of novel or better quality products for the treatment of a large number of diseases in livestock. In addition, as we understand more about the reproductive physiology of animals, the potential exists to dramatically increase the productivity of animals through better therapeutics and diagnostics for the control of many infectious diseases. Productivity can also be increased through animal breeding strategies including gene transfer, micromanipulation of embryos and gamete sex selection. As well as being a valuable reference to current knowledge in these areas, this first supplement to Comprehensive Biotechnology also looks at societal concerns over the use of antibiotics and chemical residues in meat and milk products, which are forcing biotechnologists to investigate more natural means of controlling infection by stimulating the animal's own immune system to combat infection. The identification of a variety of cytokines which are involved in regulating immune responses provides opportunities to use the animal's natural defence mechanisms to combat many infections or increase the animal's resistance to such infections. These approaches should provide tools for eventual elimination of specific diseases from counties, regions or whole continents.

  • Comprehensive Insect Physiology, Volume 8

    Endocrinology II
    • 1 Edición
    • G. A. Kerkut
    • Inglés
    Endocrinology II concerns the actions of hormones in insects, complementing Volume 7 which is concerned with the production and chemistry of insect hormones. While the preceding volume is directed mainly towards the insect endocrinologist, this volume has much of intrinsic interest to the general physiologist. It deals with the regulation of metabolism, reproduction, cuticle properties, and certain aspects of behaviour from a systems point of view and amply documents how hormones have provided basic insights into the functioning of such systems. Interference in endocrine regulation could provide future systems for insect control and this volume will provide the foundation on which the future formulation of these strategies is based. More information on diverse aspects of insect hormone action is brought together here than in any previous single work and this volume will therefore be a valuable reference source for many years to come.

    • David W. Onstad
    • Inglés
    Neither pest management nor resistance management can occur with only an understanding of pest biology. For years, entomologists have understood, with their use of economic thresholds, that at least a minimal use of economics was necessary for proper integrated pest management. IRM is even more complicated and dependent on understanding and using socioeconomic factors. The new edition of Insect Resistance Management addresses these issues and much more. Many new ideas, facts and case studies have been developed since the previous edition of Insect Resistance Management published. With a new chapter focusing on Resistance Mechanisms Related to Plant-incorporated Toxins and heavily expanded revisions of several existing chapters, this new volume will be an invaluable resource for IRM researchers, practitioners, professors and advanced students. Authors in this edition include professors at major universities, leaders in the chemical and seed industry, evolutionary biologists and active IRM practitioners. This revision also contains more information about IRM outside North America, and a modeling chapter contains a large new section on uncertainty analysis, a subject recently emphasized by the U.S. Environmental Protection Agency. The final chapter contains a section on insecticidal seed treatments. No other book has the breadth of coverage of Insect Resistance Management, 2e. It not only covers molecular to economic issues, but also transgenic crops, seed treatments and other pest management tactics such as crop rotation. Major themes continuing from the first edition include the importance of using IRM in the integrated pest management paradigm, the need to study and account for pest behavior, and the influence of human behavior and decision making in IRM.

    Although inflammation is one of the body’s first responses to infection, overactive immune responses can cause chronic inflammatory diseases. Long-term low-grade inflammation has also been identified as a risk factor for other diseases. Diet, immunity and inflammation provides a comprehensive introduction to immunity and inflammation and the role that diet and nutrition play with regard to this key bodily response.Part one, an introductory section, discusses innate and adaptive immunity, mucosal immunity in a healthy gut and chronic inflammatory diseases and low grade inflammation. Chapters in part two highlight the role of micronutrients, including zinc, selenium, iron, vitamin A and vitamin D, in inflammation and immunity. Part three explores other dietary constituents and includes chapters on intestinal bacteria and probiotics, the impacts of prebiotics on the immune system and inflammation, and antimicrobial, immunomodulatory and anti-inflammatory effects of food bioactive proteins and peptides. Further chapters explore the role of olive oil, short and long chain fatty acids and arginine and glutamine in immune functions. Nutrition, immunity and inflammation are discussed from an integrative and life course perspective in part four. Chapters focus on adverse immune reactions to foods, early nutritional programming, the impact of nutrition on the immune system during ageing, the impact of exercise on immunity and the interaction with nutrition, and the effect that malnutrition has on immunity and susceptibility to infection.With its distinguished editors and international team of expert contributors, Diet, immunity and inflammation is a comprehensive resource for those researching immunology or inflammation, nutrition scientists, and professionals in the food and nutrition industries who require an understanding of the effect that diet can have on the immune system and inflammation.
