Download or read book Non-wood Forest Products from Temperate Broad-leaved Trees written by William M. Ciesla and published by Food & Agriculture Org.. This book was released on 2002 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperate broadleaved trees grow in very different ecosystems in the northern and southern hemispheres, but are also found extensively in many tropical and subtropical mountain areas. A wide range of non-wood products are derived from temperate broadleaved trees, and their description is organized in this volume according to the part of the tree from which they are obtained (whole tree, foliage, flowers, etc.). This information is presented in order to raise awareness on, and assist in identifying, opportunities for the management and production of non-wood products from temperate broadleaved trees. The intended audience of this publication ranges from interest groups in the forest, agriculture and rural development sectors to conservation agencies in developed and developing countries.

Available in PDF, EPUB and Kindle. Book excerpt: 4.1.1 Demographic significance Confined populations grow more rapidly than populations from which dispersal is permitted (Lidicker, 1975; Krebs, 1979; Tamarin et at., 1984), and demography in island populations where dispersal is restricted differs greatly from nearby mainland populations (Lidicker, 1973; Tamarin, 1977, 1978; Gliwicz, 1980), clearly demonstrating the demographic signi ficance of dispersal. The prevalence of dispersal in rapidly expanding populations is held to be the best evidence for presaturation dispersal. Because dispersal reduces the growth rate of source populations, it is generally believed that emigration is not balanced by immigration, and that mortality of emigrants occurs as a result of movement into a 'sink' of unfavourable habitat. If such dispersal is age- or sex-biased, the demo graphy of the population is markedly affected, as a consequence of differ ences in mortality in the dispersive sex or age class. Habitat heterogeneity consequently underlies this interpretation of dispersal and its demographic consequences, although the spatial variability of environments is rarely assessed in dispersal studies.

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.

Available in PDF, EPUB and Kindle. Book excerpt: "This Directory is a facsimile reprint of the original Eva Crane classic that was published in 1984. From the thousands of plant species on which they had collected data, Eva Crane and her team selected 467 which could be justifiably described as the 'important world honey sources' of the book's title. For each plant species, data is provided on its economic and other uses, how much nectar / pollen and/or honeydew it provides, honey flow data (if any exist), and concerning the honey's chemical and physical properties."--Page 4 of cover.

Available in PDF, EPUB and Kindle. Book excerpt: Novel Aspects of Insect-Plant Interactions Edited by Pedro Barbosa and Deborah Letourneau This volume represents the forefront of two rapidly advancing areas of ecology: three-trophic-level interactions and the interdisciplinary field of chemical ecology The book focuses on the role of microorganisms as mediators of interactions between insects and plants, providing critical appraisal of studies and suggesting ways to integrate competing hypotheses of insect-plant dynamics. 1988 (0 471-83276-6) 362 pp. Arthropod Biological Control Agents and Pesticides Brian A. Croft Examining the effects of pesticides on predators and parasites and exploring methods for reducing negative impacts of pesticide use, this book focuses on the interaction of pesticides with entomophagous arthropods. It surveys the history of research in the field and discusses susceptibility assessment, lethal, sublethal, and ecological effects of pesticides, and selectivity, resistance, and resistance management. 1990 (0 471-81975-1) 723 pp. Lepidopteran Anatomy, John Eaton This single-source treatment on the anatomy of Lepidoptera provides a detailed exposition of its anatomy plus all its life stages, including the larva and adult forms of the exoskeleton, musculature, organ systems, and specialized structures. As the only thorough examination of the morphology of this insect group, it is an essential acquisition for entomologists, morphologists, and insect physiologists. 1988 (1-05862-9) 257 pp. Integrated Pest Management Systems and Cotton Production Edited by Ray Frisbie, Kamal El-Zik, and L. Ted Wilson The most complete and authoritative work available on the subject, this book brings together information on integrated pest management strategies that are applicable to cotton. It addresses economic, agronomic, and biological factors of pest management and focuses on plant resistance to pests and the genetic rationale for improving plant health. 1989 (0 471-81782-1) 437 pp.

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 322 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.
