Download or read book Grasshoppers and Grassland Health written by Jeffrey A. Lockwood and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acridids (grasshoppers and locusts) can range from being rare curiosities to abundant menaces. Some are threatened with extinction and become subjects of intensive conservation efforts, while others are devastating pests and become the objects of massive control programmes. Even within a species, there are times when the animal is so abundant that its crushed masses cause the wheels of trains to skid (the Rocky Mountain grasshopper, Melanoplus spretus Walsh in western North America in the 1860s and I 870s), while at other times the animal is alarmingly scarce (the Rocky Mountain grasshopper went extinct in the early 1900s). Why are there these extremes in one insect family, and even in a single species? The NATO workshop examined this paradox and its implications for Environmental Security, which must address both the elements of land use (agricultural production and pest management) and conservation of biodiversity. The reconciliation of these objectives clearly demands a critical assessment of current knowledge and policies, identification of future research, and close working relationships among scientists. Insects can present two clear faces, as well as the intervening gradation. These extremes require us to respond in two ways: conservation of scarce species and suppression of abundant (harmful) species. But perhaps most important, these opposite poles also provide the opportunity for an exchange of information and insight.

Available in PDF, EPUB and Kindle. Book excerpt: In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.

Download or read book Biology of Desert Invertebrates written by C. S. Crawford and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: What little we know of the biology of desert invertebrates stems largely from inferences based on intensive and repeated observations. Such informa tion is not gained easily, since despite the actual abundance of these animals, relatively few of them are ever seen. In fact, except for species impacting on the well-being of human populations, historically most have been ignored by scholars in the western world. Indeed, it was ancient Egypt, with its reverence for the symbolism of the scarab, that probably provided us with the clearest early record of prominent desert types. A more modest resurgence of the story had to wait until the arrival of the present century. To be sure, some of the more obvious species had by then been elevated by European collectors to the level of drawing-room curios ities, and expeditions had returned large numbers to museums. But by 1900 the task of describing desert species and relationships among them was still in its infancy; and as for careful natural history studies, they too were just coming into their own.

Download or read book The Food Security Biodiversity and Climate Nexus written by Mohamed Behnassi and published by Springer Nature. This book was released on 2022-10-20 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the outcome of an international cooperation between 73 scientists, experts, and practitioners from many countries, disciplines, and professional areas. As a part of a series of CERES publications, the volume attempts to contribute to the scientific debate about the food–biodiversity–climate nexus by developing a comprehensive region-specific and broader global understanding of the linkages between these areas, especially in the context of Global South. Instead of providing only modern science-based solutions for the nexus related challenges, the volume covers case studies that present mixed solutions, offering the use of traditional ecological knowledge in combination with modern science for both resilience and sustainability. This is increasingly instrumental in shaping the needed response options regarding the economic, social, and environmental future of the world. Based on a multi-regional and cross-sectoral analysis, the approach consists of: assessing the different natural and anthropogenic factors currently affecting ecosystems and their services, especially the impacts of climate change; highlighting the different linkages between the state of biodiversity and food systems in many contexts and scales; and exploring the various response mechanisms to effectively manage the implications of such linkages. Most chapters provide inputs for future relevant research and policy agendas.

Book excerpt: The Encyclopedia of Animal Behavior, Three Volume Set has engaged with great success the efforts of many of the best behavioral biologists of the 21st century. Section editors drawn from the most accomplished behavioral scientists of their generation have enrolled an international cast of highly respected thinkers and writers all of whom have taken great care and joy in illuminating every imaginable corner of animal behavior. This comprehensive work covers not only the usual topics such as communication, learning, sexual selection, navigation, and the history of the field, but also emerging topics in cognition, animal welfare, conservation, and applications of animal behavior. The large section on animal cognition brings together many of the world's experts on the subject to provide a comprehensive overview of this rapidly developing area. Chapters relating to animal welfare give a full view of behavioral interactions of humans with companion animals, farm animals, and animals in the wild. The key role of animal behavior in conservation biology receives broad attention, including chapters on topics such as the effects of noise pollution, captive breeding, and how the behavioral effects of parasites interacts with conservation issues. Animal behavior in environmental biology is highlighted in chapters on the effects of endocrine disruptors on behavior and a large number of chapters on key species, such as wolves, chimpanzees, hyenas and sharks. Clear, accessible writing complements a wealth of information for undergraduate college students about the essential concepts of animal behavior and the application of those concepts across the field. In-depth coverage of concepts, methods, and exemplar organisms serves the needs of graduate students and professionals in the field. From the use of behavior in assessing the welfare of pigs to the social behavior of insects, from animal empathy to bat brains, this authoritative reference, with its in-depth introductory articles, rich array of illustrations, interactive cross-referenced links, and numerous suggested readings, can guide the student or the professional to an expanded appreciation of the far-flung world of animal behavior. An invaluable tool for teaching and a source of enrichment and detail for any topic covered in an animal behavior course, the Encyclopedia of Animal Behavior is the definitive reference work in its field and will be for years to come. Comprehensive work which covers the usual topics along with emerging areas of animal behavior This encyclopedia contains clear, accessible writing and is well illustrated, including an online video, complimenting a wealth of information As an online reference, this work will be subject to period updating. This ensures that the work always remains current Contains in-depth introductions to the material that make each well-illustrated section come alive with the best the new content the discipline has to offer Glossary includes a compendium of behavioral terms that form a succinct mosaic of virtually every concept and phenomenon related to animal behavior Section editors, drawn from around the world, represent the best and the brightest among today's behavioral biologists and have recruited a broad range of internationally recognized experts Editors-in-Chief are experienced scientists and writers who between them have authored or edited eight books and teach courses in animal behavior at their respective universities
Download or read book Locust written by Jeffrey A. Lockwood and published by Basic Books. This book was released on 2009-04-28 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the nineteenth century, swarms of locusts regularly swept across the continent, turning noon into dusk, demolishing farm communities, and bringing trains to a halt as the crushed bodies of insects greased the rails. In 1876, the U.S. Congress declared the locust "the single greatest impediment to the settlement of the country." From the Dakotas to Texas, from California to Iowa, the swarms pushed thousands of settlers to the brink of starvation, prompting the federal government to enlist some of the greatest scientific minds of the day and thereby jumpstarting the fledgling science of entomology. Over the next few decades, the Rocky Mountain locust suddenly -- and mysteriously -- vanished. A century later, Jeffrey Lockwood set out to discover why. Unconvinced by the reigning theories, he searched for new evidence in musty books, crumbling maps, and crevassed glaciers, eventually piecing together the elusive answer: A group of early settlers unwittingly destroyed the locust's sanctuaries just as the insect was experiencing a natural population crash. Drawing on historical accounts and modern science, Locust brings to life the cultural, economic, and political forces at work in America in the late-nineteenth century, even as it solves one of the greatest ecological mysteries of our time.
Download or read book Insect Outbreaks Revisited written by Pedro Barbosa and published by John Wiley & Sons. This book was released on 2012-06-29 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abundance of insects can change dramatically from generation to generation; these generational changes may occur within a growing season or over a period of years. Such extraordinary density changes or "outbreaks" may be abrupt and ostensibly random, or population peaks may occur in a more or less cyclic fashion. They can be hugely destructive when the insect is a crop pest or carries diseases of humans, farm animals, or wildlife. Knowledge of these types of population dynamics and computer models that may help predict when they occur are very important. This important new book revisits a subject not thoroughly discussed in such a publication since 1988 and brings an international scale to the issue of insect outbreaks. Insect Outbreaks Revisited is intended for senior undergraduate and graduate students in ecology, population biology and entomology, as well as government and industry scientists doing research on pests, land managers, pest management personnel, extension personnel, conservation biologists and ecologists, and state, county and district foresters.
