Available in PDF, EPUB and Kindle. Book excerpt: The Theory and Practice of Biological Control covers conventional biological control achievement in the major crop types and in public health problems. Composed of five sections encompassing 28 chapters, this book discusses the basic information concerning developments in other biologically based alternatives to chemical pesticides. The first two sections discuss the philosophy, theory, scope, history, and the biological and ecological bases of biological control. These sections also deal with the impact of predators and the host relationships of parasitoids and pathogens. The following section presents the methodological aspects of biological control. Discussions on the variability of natural enemies as encountered in biological control work; the fitness of individuals and populations; the ways fitness is being or can be influenced by importation procedures; and the ability of imported natural enemies to adapt to the new environment are included. The fourth section outlines the accomplishments of conventional biological control in various types of crops, forests, and public health areas. Lastly, the various components of integrated pest control other than conventional biological control that forms the essential ways used in the integrated control approach are covered in the last section of the book. This book is an ideal source for plant pathologists and researchers, microbiologists, parasitologists, and public health professionals.

Available in PDF, EPUB and Kindle. Book excerpt: This book signaled a shift in the understanding of the global reorganization of biological species during the Anthropocene. The encouragement of acclimatization and naturalization of new species gave way to managing the ramifications of the changes that introductions bought to ecologies, landscapes and environments. The 19th century environments of the new world - land and sea - became testing grounds for the introduction of new assemblages of people and plants, economies and animals, cultures and coastlines. But some species became out-of-control threats to environments across the globe. These changes have enduring impacts, some adverse, some beneficial, that are dynamic, unpredictable and often oscillating.

Download or read book Behavioural Ecology of Fishes written by Felicity Anne Huntingford and published by CRC Press. This book was released on 1993-12-23 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reflecting a decade's worth of changes, Human Safety and Risk Management, Second Edition contains new chapters addressing safety culture and models of risk as well as an extensive re-working of the material from the earlier edition. Examining a wide range of approaches to risk, the authors define safety culture and review theoretical models that elucidate mechanisms linking safety culture with safety performance. Filled with practical examples and case studies and drawing on a range of disciplines, the book explores individual differences and the many ways in which human beings are alike within a risk and safety context. It delineates a risk management approach that includes a range of techniques such as risk assessment, safety audit, and safety interventions. The authors address concepts central to workplace safety such as attitudes and their link with behavior. They discuss managing behavior in work environments including key functions and benefits of groups, factors influencing team effectiveness, and barriers to effectiveness such as groupthink.

Both basic and applied information are made available, making the book a must-have for a wide spectrum of users. For example, an understanding of the natural and the social aspects of the marshes, as described here, is an obvious prerequisite for a pest management plan in this area. Scholars interested in wetlands can use this book as a guide to compare different wetlands areas in Asia. The bibliography section contains valuable references to the marsh areas and research in the field. This book serves as an up-to-date comprehensive source of information on different aspects of the southern marshes of Iraq and is aimed at academic scholars, environmentalists, and decision makers.
Download or read book Integrated Mosquito Control Methodologies Biocontrol and other innovative components and future directions written by Marshall Laird and published by London ; Toronto : Academic Press. This book was released on 1983 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book supplements the information given in Volume 1 on the conventional methods of chemical control, with accounts of the ecological basis and economic aspects of bio-control. Special attention is given to innovative approaches such as the use of entomopathogenic bacteria. The other control methods discussed include the use of appropriate insect growth regulators, organo-phosphate and carbamate poisoning of adults and ways in which communities can help to reduce the sources of favourable environments for mosquito reproduction.**FROM THE PREFACE: As this second and last volume of Integrated Mosquito Control Methodologies goes to press, it would be heartening to be able to record a rapidly diversifying application of such solutions to pest and vector problems. Regrettably, this is not yet possible. Our contributors have proffered much information which will serve as the basis for future such methodologies, with attention to relevant application technology, and a number of the examples they furnish illustrate ways in which two or more basically different approaches (chemical, environmental, or biological) have been purposely or fortuitously combined in the past. Yet in assembling the chapters, it proved impossible to obtain any accounts of integrated control projects so far designed and implemented for mosquito suppression on a larger scale than that of the operation against Aedes aegypti on the atoll of Funafuti (human population circa 2000), Tuvalu, an outline of which concludes this work.**Nevertheless, this can serve as a model for far larger undertakings employing the same innovative and conventional control agents (all of them currently available commercially) and appropriate new ones as they are developed, also for similar approaches to public relations and community involvement. For it is confidently believed that the Tuvalu methodology could be adapted with equal effect against other Culicidae of health importance, from the indigenous tropical Pacific container-breeders (e.g., Aedes polynesiensis), transmitting Bancroftian filariasis, to small-island populations of such surface-water breeders as the Melanesian malaria vectors of the Anopheles farauti complex--where exophily would pose new adulticiding problems, while the larval habitats would be open to a wider range of biocontrol agents, including appropriate larvivores, the importation of which would be unlikely to pose threats to the economy in islands lacking the natural basis for a freshwater fishery. We specify small-island populations of vector mosquitoes in this context because the simplification of ecological circumstances pertinent to disease transmission, and of public relations issues involving the humans being protected, make it far easier to develop integrated control methodologies there than in continental areas with heavy urbanization.
Download or read book The Physiology of Fishes written by Margaret E. Brown and published by Academic Press. This book was released on 2013-10-22 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physiology of Fishes, Volume II: Behavior focuses on the physiology of fishes, as well as nervous and visual systems, sense organs, fish behavior, and pigment of fishes. The book first offers information on the nervous system, including the telencephalon, mesencephalon, metencephalon, medulla oblongata and spinal cord, autonomic nervous system, and functional development of the nervous system. The manuscript then elaborates on the sense organs, acoustico-lateralis system, and olfactory and gustatory senses of fishes. Discussions focus on component parts of the visual system, photoreceptive functions, lateral line, and the labyrinth. The manuscript takes a look at the ethological analysis of fish behavior and reproductive and parental behavior. Topics include coordinating and releasing mechanisms, ecological relationships, endocrine mechanisms, and motor processes. The text also touches on electric organs, luminous organs of fishes, and pigment of fishes. The publication is a valuable reference for readers interested in the physiology of fishes.

This book was released on 2012-12-02 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sperm Competition and the Evolution of Animal Mating Systems describes the role of sperm competition in selection on a range of attributes from gamete morphology to species mating systems. This book is organized into 19 chapters and begins with the conceptualization of sperm competition as a subset of sexual selection and its implications for the insects. The following chapter describes the relationship between multiple mating and female fitness, with an emphasis on determining the conditions under which selection on females is likely to counteract selection on males for avoiding sperm competition. Other chapters consider the female perspective on sperm competition; the evolutionary causation at the level of the individual male gamete; and the correlation of high paternal investment and sperm precedence in the insects. The remaining chapters are arranged phylogenetically and explore the sperm competition in diverse animal taxa, such as the Drosophila, Lepidoptera, spiders, amphibians, and reptiles. These chapters also cover the evolution of direct versus indirect sperm transfer among the arachnids or the problem for kinship theory presented by multiple mating and sperm competition in the Hymenoptera. This book further discusses the remarkable potential for sperm competition among certain temperate bat species whose females store sperm through winter hibernation and the mixed strategies and male-caused female genital trauma as possible sperm competition adaptations in poeciliid fishes. The concluding chapter examines the predictions concerning testes size and mating systems in the primates and the possible role of sperm competition in human selection. This book is of great value to reproductive biologists and researchers.
