  • 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.

    • 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.

    • 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.

  • Reproductive and Developmental Behaviour in Sheep

    An Anthology from ``Applied Animal Ethology''
    • 1 Edición
    • A.F. Fraser
    • Inglés
    Although intensive husbandry is increasingly applied to sheep, most sheep production around the world is still based on the extensive system. Under these conditions, attempts to improve productivity must take particular account of reproductive and developmental behaviour, as successful sheep production depends heavily on optimal reproduction and development. These topics are presented in this anthology of selected publications on sheep behaviour. The papers have been taken from ten years of Applied Animal Ethology (now Applied Animal Behaviour Science) from its inception in December 1974 to the end of its publication under that title in 1984.

  • 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.

  • 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.

  • Plant Diseases

    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.

  • Insect Resistance Management

    Biology, Economics, and Prediction
    • 2 Edición
    • 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.

    • Nikolai N. Smirnov
    • Inglés
    The Physiology of Cladocera is a much-needed summary of foundational information on these increasingly important model organisms. This unique and valuable summary is based on the world's literature, including Russian research not widely available until now. It offers systematically arranged data on the physiology of Cladocera, assisting with explanation of their life and distribution, as well as discussion on directions of future research. Special expert contributions in genetics, immunology, and cytology round out the physiological chapters and provide comprehensive insight into the state of knowledge of Cladocera and its underlying mechanisms. Cladocera crustaceans make up a significant part of the natural communities and biological productivity of fresh waters. In recent decades, they have become globally studied for many purposes, including systematics, genetic, molecular, ecological and evolutionary biology studies. They are also used as "sentinel" organisms for assessing water quality and the environment. In addition, the genome of Daphnia (a genus within Cladocera) was recently sequenced and published, giving this system a much wider exposure. It has also led to a rapidly growing awareness of the importance of understanding physiological processes as they relate to evolutionary and ecological genomics and ecogenomic toxicology. Despite the increasing use of Cladocera in research and study, physiological background information on these creatures is fragmentary. Hundreds of unconnected publications have been accumulated on their physiology, and a synthesis and general representation of the literature has been much needed for the many researchers working with this organism. The Physiology of Cladocera stands alone as a valuable and comprehensive offering in this area for many researchers and students.

    • Inglés
    Sexual Selection: Perspectives and Models from the Neotropics presents new sexual selection research based upon neotropical species. As neotropical regions are destroyed at an alarming rate, with an estimated 140 species of rainforest plants and animals going extinct every day, it is important to bring neotropical research to the fore now. Sexual selection occurs when the male or female of a species is attracted by certain characteristics such as form, color or behavior. When those features lead to a greater probability of successful mating, they become more prominent in the species. Although most theoretical concepts concerning sexual selection and reproductive strategies are based upon North American and European fauna, the Neotropical region encompasses much more biodiversity, with as many as 15,000 plant and animal species in a single acre of rain forest. This book illustrates concepts in sexual selection through themes ranging from female cryptic choice in insects, sexual conflict in fish, interaction between sexual selection and the immune system, nuptial gifts, visual and acoustic sexual signaling, parental investment, to alternative mating strategies, among others. These approaches distinguish Sexual Selection from current publications in sexual selection, mainly because of the latitudinal and taxonomic focus, so that readers will be introduced to systems mostly unknown outside the tropics, several of which bring into question some well-established patterns for temperate regions.
