  • Agricultural Ecology and Environment

    • 1 Edición
    • B.R. Stinner + 2 más
    • Inglés
    The increased use of chemical fertilizers and pesticides in crop production has adversely affected both the environment and the agricultural economy. Not only has it led to environmental pollution, but also the increasing costs of chemical inputs and the low prices received for agricultural products have contributed to economic unprofitability and instability.The International Symposium on Agricultural Ecology and Environment was organised in order to discuss ways of achieving the goals of economically and environmentally sustainable agriculture. It is apparent that a truly multidisciplinary effort is required and for this reason the meeting was attended by authors from many different disciplines and geographical locations. Although their papers reflect a wide diversity of agroecosystem types and examples, several common themes emerge: the increased importance of biotic control of ecosystem processes in lower input systems; the key role of soil organic matter in stabilizing nutrient cycling; the importance of agricultural landscape diversity and complexity; the importance of studying ecological processes in natural and agricultural ecosystems; the critical need to integrate socio-economic and ecological approaches.

    • 1 Edición
    • Volumen 19
    • G.B. Marini-Bettòlo
    • Inglés
    Genetic research in some fundamental crops, together with the use of chemicals as pesticides and fertilizers, opened the way in the 1950s and 1960s to great changes in methodology in agriculture - with astonishing results in the tropics. This change became known as the Green Revolution - a truly great revolution in methods and materials which, when applied with intelligence, made possible in a few years the achievement of complete sufficiency in cereals production in South and South East Asia, Mexico and South America. After 20 years of continuous success, aspects of the Green Revolution need to be rediscussed in the light of new findings and possibilities offered by scientific and technological progress - and negative side effects on environment and health. These papers examine the present state of agriculture, and indicate the way forward for its development, especially in the tropics and, in particular, Africa and South America. The need for more research is stressed; priorities in the application of this research are discussed, such as the economic aspects of any new system to be adopted, and the need to respect the ecological equilibria of different environments and the balance of energy input/output in a given agrosystem.

    The Fine Structure of Algal Cells is a hybrid between a review and a comprehensive descriptive work on fine structure of algae. Such fine structural data are important for any consideration of the classification of algae and for attempting to analyze their phylogenetic relationships. ”Fine-structure” has provided many vital keys to the understanding of the interrelationships and phylogeny of the algae. Notably, the trend in algal fine structure work is toward use of electron microscopy to try to understand the functions of cells and organelles under both normal and experimental conditions. This book brings together information which has been gathered by electron microscopists. It considers 13 classes of algae: Chlorophyceae, Haptophyceae, Prasinophyceae, Bacillariophyceae, Chloromonadophyceae, Phaeophyceae, Euglenophyceae, Dinophyceae, Eustigmatophyceae, Cryptophyceae, Xanthophyceae, Rhodophyceae, and Chrysophyceae. It covers the main structural features of the various classes and the organelles present in typical cells. The book also describes the algal cell covering, flagella, pyrenoid, eyespot, nucleus, and ejectile organelles,as well as membranes, envelope, and stroma of algal chloroplasts. Lastly, it also explains the algal cell division. This book will help students visualize and compare algal structure, and at the same time provide enough references so that research workers can enter the literature to find out more precise details from the original sources.

It reviews the literature and provides numerous examples demonstrating the use of water activity to predict the reactions of microorganisms or the stability of food components. It also highlights cases where water activity is not a reliable predictor of events and considers some interesting interactions with other environmental parameters. Comprised of 11 chapters, this volume begins with an overview of water in foods and solutions, water activity values for foods, and water relations of enzyme activity. It then discusses lipid oxidation, enzyme reactions and non-enzymatic browning, and several other food-related factors. The reader is also introduced to water relations of microbial growth; the effects of water on microbial survival; the spoilage and preservation of foods at various levels of water activity; the water relations of food-borne pathogens such as Salmonella and toxigenic molds; the importance of water activity in non-microbiological aspects of food processing and storage; and the influence of atmospheric relative humidity on sanitation and the protection of food products. This book is an important source of information for researchers in food microbiology and microbial water relations.

    • Inglés
    Herbivorous Insects: Host-Seeking Behavior and Mechanisms addresses mechanisms of searching behavior leading ultimately to host location of herbivorous insects. It is divided into four sections, wherein the first two sections deal with neurophysiology and the diversity of behavioral induction cues. The third section covers the searching mechanisms as affected by insects' breadth of diet. The last part examines the evolutionary analysis of the behavioral and physiological adaptations in insect/host plant relations. This book starts with an introduction to the chemical sensory system as it relates to host selection in general. This is followed by considerable discussions on host-seeking behavior and allied patterns in behavior. This text also includes the study of oviposition behavior in butterflies belonging to Papilionidae. The third section presents host selection and colonization by three insects within the saprophage-predator continuum, namely, Hylurgopinus rufipes, Scolytus multistriatus, and Pissodes strobi. The behaviors by which certain oligophagous insects locate and select food plants are also considered. The concluding part addresses the unifying theme and the diversity of responses of phytophagous insects to plants. The book provides direction toward developing a unifying theme and improving the ability to unravel the complexities of insect/plant interactions. Behaviorists, ecologists, entomologists, evolutionary biologists, and physiologists will find this book invaluable.

    • Inglés
    Throughout history, man has, by over-use, consistently reduced the productive capacity of dry lands. This degradation of one-third of the land area of the globe is, unfortunately, increasing. In recent years, world interest has turned to the problems of pollution of the environment and the impending food shortage as world population grows explosively. Thus the attention of international and other agricultural bodies has turned to the need for preserving and developing more effectively the agricultural potential of these areas.This book provides a comprehensive review of present knowledge of the agriculture of dry lands, with special emphasis on measures for conserving their natural resources. Management practices are described which aim at optimizing productivity of rainfed and irrigated agriculture without adverse effects on sustainability. Land use in the dry regions, and its evolution throughout history is described and analysed, and the lessons to be learnt from destructive technologies are stressed. In particular, current proposals for an alternative agriculture are discussed and their justification is questioned. This is a generalist work, which specialists can also find interesting, not only in their own discipline but as a concise way of acquainting themselves with the state-of-the-art in associated fields. Increasing specialisation with each discipline using its own vocabulary leads inevitably to communication problems, and the need for multi-disciplinary teams makes inter-discipline communication indispensible.

    • Inglés
    This book aims to up-date our present understanding of the origin of cultivated rice and in doing so involves different disciplines of biology and the archaeological-histo... sciences. Various recent discoveries are reviewed and questions posed for further consideration by the reader.The book covers a wide range of studies on problems relative to the origin of cultivated rice, placing emphasis on ecological and genetical aspects. Comparisons are made between two cultivated rice species, independently evolved in Asia and Africa from respective wild progenitors. Phenomena are observed during mixed planting and hybrids discussed. Detailed information is presented about Asian common wild rice, thought to be the ancestor of common rice. The dynamics of domestication are considered with regard to hybridization, selection, formation of weedy types and the accumulation of genetic diversity. Also included are recent archaeological findings in relation to the beginnings of rice culture, leading to the hypothesis of diffused origins. Cultivars of common rice fall into one of two types called Indica and Japonica. The dynamics of differentiation are discussed, giving evidence and different hypotheses. Information on the genetic bases and functions of various reproductive barriers found between the cultivated and wild taxa is presented and discussed. The practical aspects of crop-evolutionary studies concerned with the breeding phylosophy and germplasm conservation are briefly commented on and arguments for rediversification of crop germplasm and conservation of the environment given.Senior scientists and post-graduate students interested in rice genetics, crop evolution, and related sciences will find this book invaluable.

  • Deer Antlers

    Regeneration, Function and Evolution
    • 1 Edición
    • Richard J. Goss
    • Inglés
    This is a book about one of nature's most remarkable accomplishments. When deer grow antlers they are actually regenerating anatomically complex appendages - something that no other mammal can do. The rate at which antler elongate makes them the fastest growing structures in the animal kingdom. Profoundly affected by male hormones, these secondary sex characters grow into massive tumors if the deer possessing them is castrated. These and other unique characteristics have made antlers the focus of extensive scientific research that addresses some provocative questions: From what tissues do antlers develop? By what morphogenetic mechanisms are they regenerated every year? What social functions prompted their initial evolution? How are they influenced by hormones, and by the seasonal daylength fluctuations that regulate their annual replacement cycles? These and many other questions are considered in this comprehensive account of antlerology.Students of development, evolution, and behavior will find much to appreciate in this volume, as will ecologists, wildlife biologists, and zookeepers. It is a rich source of information for endocrinologists and physiologists interested in the relationship of antlers to the reproductive cycle. The orthopedists will find the study of antlers a valuable model of skeletal growth and bone disease, and the purported medicinal properties of velvet antlers will be a subject of interest to the pharmacologist.Deer Antlers: Regeneration, Function, and Evolution is as scientifically accurate as it is readable. It does not answer all questions about these unique appendages, but it is certain to arouse curiosity about the many unsolved problems of how antlers grow, die, and are shed in the course of a single year.

    Until the 1980s, global increases in food production exceeded the concomitant growth of human populations. However, progressively agriculture is becoming unable to meet the world-wide per capita needs for food. Unless there is major international cooperation in addressing the problems associated with population control, it is predicted that the global human population will reach more than 14 billion by the year 2050, with provision of adequate food, fuel and space for such an increased population unachievable.These problems are accentuated by factors such as world-wide reductions in soil fertility, the accelerating degradation of land that is suitable for food production through soil erosion, the world-wide trend for migration of human populations from rural habitats to cities and extremely rapid rates of global deforestation.Possib... solutions to global sustainability in agriculture and natural resources must involve an integration of ecological, sociological, cultural, and economic considerations, as well as mandated international and national policies. This publication outlines these problems and attempts to seek solutions.

    • Inglés
    Twelve years' analysis of natural grassland and experimentally managed meadows have produced this unique set of data on the structures and physiological functions of primary producers, consumers and decomposers. Obtained during the 1973-1985 Ecosystem Study on Highland Meadows in Czechoslovakia, such original information is rare in scientific literature. The aim of the study was to define the functioning of these grasslands and their changes under different impact of man, and to examine the ecological function of those ecosystems in the intensively managed catchment area. Hence, this book contains deep analyses of soil microorganisms, their functions in decomposition and soil forming processes - leading to the evaluation of the whole carbon cycle - as well as dealing with nitrogen pathways in the experimental plots - resulting in precise determination of the full nitrogen cycle. Procedures used in practical agriculture, such as cutting, fertilization and renovation, have also been applied, producing evaluations from both ecological and economical view-points.The book's integrated ecosystem approach to grasslands, its deep professional analyses in each section, along with the synthesis on each particular level and across all levels, renders it an invaluable, informative text, comprising extensive figures and tables and a substantial bibliography of world-wide sources.
