  • Seed Dispersal

    • 1 Edición
    • David R. Murray
    • Inglés
    Seed Dispersal focuses on the mechanics and processes involved in seed dispersal, including its implications in ecology, animal behavior, plant and animal biogeography, speciation, and evolution. The selection first elaborates on the aerial motion of seeds, fruits, spores, and pollen and seed dispersal by water. Discussions focus on seed dispersal by rain, river, and flood, effective seed dispersal by ocean currents compared to other vectors, aerodynamic forces and their effects, and launching and release mechanisms. The text then takes a look at seed dispersal syndromes in Australian Acacia, including inference of dispersal syndromes, seed dispersal syndromes, ecological consequences of seed dispersal, and evolutionary derivation of dispersal syndromes. The publication ponders on seed dispersal by fruit-eating birds and mammals, rodents as seed consumers and dispersers, and seed dispersal in relation to fire. Topics include fire as a dispersal vector, long distance dispersal, granivorous rodents and the fates of seeds, determinants of the fate path, population ecology of seed dispersal, and foraging for fruits. The selection is a valuable reference for researchers interested in the factors involved in seed dispersal.

  • Vehicle Traction Mechanics

    • 1 Edición
    • Volumen 3
    • R.N. Yong + 2 más
    • Inglés
    The fundamental problem in the study of vehicle mobility is the development of traction between the vehicle and the supporting terrain. The mechanics of energy transfer will essentially control the final performance of the surficial machine. Determining and predicting the capability of a particular piece of machinery to traverse successfully a specific piece of terrain is very complex, particularly as the characteristics and properties of different types of terrain cover vary considerably, as do the many types of vehicle and their running gear.The material that forms the basis of this book has been gathered over many years of study both in the laboratory and in the field. It studies vehicle traction mechanics from the viewpoint of the interaction between the vehicle and the ground surface. The types of machines covered include earth-moving, forestry, agricultural, and construction machines. In addition, the mechanisms involved in the development of traction and the working of the terrain through cultivation, construction and surface disturbances are examined. The book also addresses the problems of off-road mobility and terrain trafficability, especially from the terrain-support and terrain interaction points of view. It is the authors' aim that the book will provide the reader with the ability to both analyze and predict the traction capability of his proposed machinery, and also to anticipate the kinds of reactions that will occur in the ground and at the ground surface.

  • The Biology and Management of Lobsters

    Physiology and Behavior
    • 1 Edición
    • Inglés
    This two-volume work presents a summary and review of the current state of lobster biology, ecology, physiology, behavior, and management. It emphasizes the biology of clawed lobsters (Nephropidae) and spiny lobsters (Palinuridae), with attention also given to slipper lobsters (Scyllaridae) and coral lobsters (Synaxidae).The first chapter of Volume 1 provides an overview of the general aspects of lobster biology that serves as an introduction for readers of both volumes. Subsequent chapters examine the topics of growth, neurobiology, reproduction, nutrition, pathology, social behavior, and migration patterns.The chapters in Volume II consider the ecology, population dynamics, fishery biology, and aquaculture of spiny and clawed lobsters. The topics selected in both volumes represent areas of current research whose findings have not been previously synthesized into a coherent form.An important feature of these volumes is the emphasis on the interaction between biology and management and culture. Many of the contributors have done research in both applied and basic biology and can articulate both points of view. The interaction between basic and applied research is of fundamental importance in these volumes in which management aspects of the research have been integrated with the basic biology of lobsters.The Biology and Management of Lobsterswill be of interest to crustacean biologists, marine biologists and ecologists, zoologists, physiologists, animal behavior researchers, aquaculturalists, fisheries biologists and managers of fisheries, neurobiologists, pathologists, and food scientists.

  • Subjective Equilibrium Theory of the Farm Household

    • 1 Edición
    • Volumen 3
    • C. Nakajima
    • Inglés
    It is obvious that most of the agricultural production in the world is under the control of farm households (or family farms). This book aims to translate the characteristics of the farm household as an economic entity, into an economic theory. The book was originally written in Japanese, but various modifications have been made and new information added to the English version. The author defines the farm household as an economic entity which is a complex of the farm firm, the labourer's household and the consumer's household, and whose behavioural principle is utility maximization. The main purpose of the book is to construct a theoretical model of the decision-making behaviour of the farm household. For this purpose the method of subjective equilibrium analysis, which was used by J.R. Hicks for the consumer's household and the firm in Value and Capital, has been applied to the farm household. The major motif of the book may therefore be called ``Hicksian motif''. In analyzing the subjective equilibrium of the farm household, this book extends the Marshallian concepts of consumer's surplus and producer's surplus, by developing the three new concepts of labourer's surplus, self-employed producer's surplus and consumer's surplus. The analyses using the five concepts of economic surplus are the minor motif of the present book, which the author calls ``Marshallian motif''.Another important characteristic of this book lies in the presentation of newly developed theories of land rent. The author has tried to integrate the theory of leasehold tenancy (i.e. fixed rent tenancy) and that of share tenancy with subjective equilibrium theory of the farm household. In his foreword, John W. Longworth of the International Association of Agricultural Economists says ``From time-to-time an academic treatise appears which is truly different. This is one such book. It presents a self-contained normative theory of the farm household which is much more than just an elegant development of Hicksian and Marshallian ideas. Professor Nakajima introduces new concepts and develops a simple model of the farm household. He then extends this model in various ways to examine the subjective equilibrium of farm households under a wide range of economic circumstances. The exposition is clear and logic with each step in the argument explained in detail using both rigorous mathematical notation and easy to follow diagrams... With this book Nakajima is making his Life's Work available to non-Japanese Agricultural Economists. The international profession of Agricultural Economics will be richer for it.''

  • Diseases of Sugarcane

    Major Diseases
    • 1 Edición
    • C. Ricaud + 3 más
    • Inglés
    An extensive volume of Sugarcane Diseases and their World Distribution (Vol. I) was published by Elsevier under the auspices of the International Society of Sugar Cane Technologists in 1961. The present volume was intended to be a new edition of the book, but so many changes were required that a new book was needed. Only three chapters have been kept with slight amendments. The other chapters have been completely re-written. In fact with changes in importance of major diseases, four diseases previously treated have been left out; on the other hand, three new topics have been included in the new book, two new diseases and a chapter on sugarcane quarantine.The first chapter gives a brief account of the anatomy, morphology and physiology of the sugarcane plant to facilitate terminology and especially for a better appreciation of the effect of disease on the growth of the crop. Diseases are extensively treated as in Volume I, with a very good description of their symptoms and variation under different conditions and severity, all well illustrated by black and white figures and in a set of colour plates at the end of the book which will prove of valuable help for identification. The causal agents of the diseases are described giving synonyms, cultural characteristics, isolation methods and present knowledge on race variation, an aspect on which there has been quite an advance in knowledge since Volume I was published. New techniques of diagnosis are also given. Advances in research on the diseases over the last 25 years are well covered and supported by an extensive bibliography at the end of each chapter.The book has been edited by people having first hand experience in the field and in research on these diseases. Authors have been selected from among the most knowledgeable all over the sugar cane world, especially with due regard to the importance of the different diseases in their countries.The book should prove of immense value to those concerned with practical aspects of plant disease control in the field: pathologists, agronomists and crop specialists, including consultants, to those concerned with quarantine of the crop, for university lectures and students, and research scientists.In a pre-publication review D.J. Heinz and S.A. Ferreira of the Hawaiian Sugar Planters' Association stated: ``Much has changed and new information generated since the original version of this book was published in 1961. This new edition incorporates most of it, providing both the laboratory and field sugarcane pathologist a complete and authoritative guide to the major sugarcane diseases of the world. It is the best single book available on sugarcane diseases.''

  • Trap Responses of Flying Insects

    The Influence of Trap Design on Capture Efficiency
    • 1 Edición
    • R. C. Muirhead-Thompson
    • Inglés
    Insect trapping is a basic field research tool for many biologists, whether they are studying insect pests, disease vectors or insect ecology for its own sake. Any field entomologist contemplating a new insect trapping program or looking to improve or develop an existing scheme will benefit from this broad review of flying insect traps, in which the author draws on a wide variety of methods used by different research projects from all over the world. Over the years a great many traps have been developed and endlessly modified to suit particular species, habitats, and research requirements. In virtually every case the design of the trap interacts with the specific behavior of the insects involved to bias trap efficiency. In addition, the limited dialogue between workers in different subject disciplines and habitats has caused a shortage of new information available to field entomologists as a whole.

  • Herbivores: Their Interactions with Secondary Plant Metabolites

    The Chemical Participants
    • 2 Edición
    • Gerald A. Rosenthal + 1 más
    • Inglés
    It has been more than ten years since the first edition of this book was published. During this time, our understanding of the interactions between plants and the animals that consume them, as mediated by secondary compounds (allelochemicals) of plants, has grown dramatically.In the Herbivores: Their Interactions with Secondary Plant Metabolites, Second Edition, only those areas of research where significant progress has been made since 1979 are included, and most of the contributing authors are new. This edition has been split into two volumes due to the vast amount of new material that has been generated on this subject.Both volumes will be of interest to evolutionary biologists, agriculturists, chemists, biochemists, physiologists, and ecologists.Volume 1, provides an exhaustive update and review of the chemical and biochemical bases for the role and function of allelochemicals in their defense against herbivores.Volume 2, scheduled for publication in April 1992, provides a current update of the research on the ecological roles and evolutionary nature of secondary plant metabolites in their interactions among plants and as protective agents against environmental stresses such as consumption by herbivores.

  • Towards a Second Green Revolution

    From Chemical to New Biological Technologies in Agriculture in the Tropics
    • 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.

  • Processes and Control of Plant Senescence

    • 1 Edición
    • Volumen 8
    • Y.Y. Leshem + 2 más
    • Inglés
    This monograph provides basic and empiric information underlying processes believed to be involved in the doubtless multifunctional plant senescence syndrome. While essentially assuming a `basic science' approach the authors, drawing on data obtained from many of the main laboratories and research centres involved in senescence research the world over, and also on findings of the research groups they are associated with, have described how principles of basic science have been applied to practical problems, and have outlined the partial means presently available to man for achieving plant senescence control. Moreover, information is provided on current problems in the forefront of senescence research. This approach will hopefully engender further enquiry and lead at least to partial solutions to some of the as yet unsolved problems.The book will be an asset to the book shelves of students on advanced courses in agriculture, biology and biochemistry as well as scientists and research workers, university and agricultural research station libraries and horticulturalists.

    • 1 Edición
    • C. Barigozzi
    • Inglés
    This book consists of the proceedings of a symposium organized by the Accademia Nazionale dei Lincei, Rome. The proceedings are unusual in that it is a rare event to see archaeologists and geneticists coming together to discuss the connection between historical facts and biological phenomena. The aim of the symposium was to discuss the origin of some important cultivated plants (wheat, maize, barley, oat, legumes and fruit trees) not only in relation to genetical mechanisms but also as a complex of historical facts recognizable through archaeological research.This international Meeting based on interdisciplinary concepts, met with a prompt and positive reaction from all those specialists invited to attend. The book itself is an unparalleled contribution to the interdisciplinary knowledge on the origin of crop plants and agriculture.

  • The Bottlenose Dolphin

    • 1 Edición
    • Stephen Leatherwood + 1 más
    • Inglés
    Because of their exposure in marine parks, movies, and television as well as their presence in tropical and warm-temperature waters around the world, bottlenose dolphins are among the most familiar of marine mammals. Since they are relatively easy to obtain and they thrive in captivity, these dolphins have been used in a great variety of studies. Work with the bottlenose has provided insight into the sensory mechanisms, communication systems, energetics, reproduction, anatomy, and other aspects of cetacean biology. This volume presents the most recent biological and behavioral discoveries of bottlenose dolphins from different regions and compares bottlenose dolphins as a group with other species of animals.

  • Dinoflagellates

    • 1 Edición
    • David L. Spector
    • Inglés
    The book begins with a general introduction and a taxonomic description of the dinoflagellates both to acquaint those unfamiliar with this group of organisms and to set the tone for the rest of the volume. It then addresses the following topics: cell biology (cell cortex, nuclear structure, cell cycle and mitosis, sexual reproduction, cysts and unusual inclusions); biochemistry (physiology and biochemistry, blooms and toxins, and biorhythms); and genetics. In addition, a comprehensive chapter on cell culturing provides the reader with an understanding of the growth conditions and requirements of various dinoflagellates and a simple to follow listing of culture media, all expressed in similar units for ease of comparison. The volume closes with a chapter on evolution which evaluates many of the features of dinoflagellates discussed in the text in terms of evolutionary significance.We hope that this treatise will be of use to research workers and students in the area of dinoflagellate biology and in other areas of biology in which dinoflagellates may be used as a model system for studying various biological problems.

All of these topics are integrated into a main theme of "enabling plant biotechnology" relevant to the production of secondary metabolites.This book will be of great value to all plant cell biologists and molecular geneticists, and all those interested in the integration of plant science and bioprocess engineering for development of enabling technology relevant to the production of plant secondary metabolites.

  • 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.

    • Inglés
    The second edition of Avian Immunology provides an up-to-date overview of the current knowledge of avian immunology. From the ontogeny of the avian immune system to practical application in vaccinology, the book encompasses all aspects of innate and adaptive immunity in chickens. In addition, chapters are devoted to the immunology of other commercially important species such as turkeys and ducks, and to ecoimmunology summarizing the knowledge of immune responses in free-living birds often in relation to reproductive success. The book contains a detailed description of the avian innate immune system, encompassing the mucosal, enteric, respiratory and reproductive systems. The diseases and disorders it covers include immunodepressive diseases and immune evasion, autoimmune diseases, and tumors of the immune system. Practical aspects of vaccination are examined as well. Extensive appendices summarize resources for scientists including cell lines, inbred chicken lines, cytokines, chemokines, and monoclonal antibodies. The world-wide importance of poultry protein for the human diet, as well as the threat of avian influenza pandemics like H5N1 and heavy reliance on vaccination to protect commercial flocks makes this book a vital resource. This book provides crucial information not only for poultry health professionals and avian biologists, but also for comparative and veterinary immunologists, graduate students and veterinary students with an interest in avian immunology.

  • Fearing Food

    Risk, Health and Environment
    • 1 Edición
    • Julian Morris + 1 más
    • Inglés
    Environmental and consumer activists have for a long time blamed pesticides, fertilizers and other aspects of intensive farming for causing environmental degradation and human disease. Yet, as the authors in this book show, intensive farming has enabled growth in food production at a rate greater than population growth, thereby ensuring that people are better fed than ever before, whilst simultaneously limiting the effect of farming on the environment.The authors debunk numerous pervasive myths, including:Myth: Pesticides are bad for the environment and bad for human healthFact: Synthetic pesticides enable the production of large quantities of fresh fruit and vegetables, which means that people are better protected against cancer. In addition, the synthetic pesticides themselves are often less toxic than natural pesticides. Overall, synthetic pesticides present a net gain in health terms.Myth: Antibiotic resistance in animals is spreading to humans.Fact: The use of antibiotics in young animals keeps meat prices low and does not materially contribute to antibiotic resistance in humans.Myth: Nitrate fertilizers are a threat to human health.Fact: Nitrate fertilizers are probably beneficial to human health.Myth: Genetically modified organisms (GMOs) are bad for the environment and bad for our health.Fact: Many environmental problems associated with agriculture can be reduced by using GMOs, which have the potential to improve yields and quality which simultaneously reducing associated inputs, such as fertilizers, herbicides and pesticides. Commercially produced GM foodcrops have no known impacts on human health and future GM foodcrops are likely to have health benefits (enabling such things as low-fat chips/french fries and non-allergenic peanuts).Myth: Instances of food poisoning would be reduced if we had more regulations.Fact: Instances of food poisoning in the UK may have been exacerbated by over-cautious government regulation.Myth: Subsidies are needed to order to ensure that food and fish are produced in environmentally sound ways.Fact: Subsidies to fisheries and farming have caused widespread environmental degradation.Myth: Packaging and transporting food is environmentally unfriendly.Fact: Packaging enhances the shelf life of products and reduces wastage during transport. Transporting food allows society to take advantage of different environmental and socio-economic conditions that exist in different places.
