Download or read book Westcott s Plant Disease Handbook written by R. K. Horst and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1242 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was a compliment to me to be asked to prepare the fourth edition of Westcott's Plant Disease Handbook, and the decision to accept the responsi bility for the fourth edition and now the fifth edition was not taken lightly. The task has been a formidable one. I have always had a great respect professionally for Dr. Cynthia Westcott. That respect has grown considerably with the completion of the two editions. I now fully realize the tremendous amount of effort expended by Dr. Westcott in developing the Handbook. A book such as this is never finished, since one is never sure that everything has been included that should be. I would quote and endorse the words of Dr. Westcott in her preface to the first edition: "It is easy enough to start a book on plant disease. It is impossible to finish it. " This revision of the Handbook retains the same general format contained in the previous editions. The chemicals and pesticides regulations have been updated; a few taxonomic changes have been made in the bacteria, fungi, and mistletoes; the changing picture in diseases caused by viruses and/or viruslike agents has been described. A few new host plants have been added, and many recently reported diseases as well as previously known diseases listed now on new hosts have been included. In addition, photographs have been replaced where possible, and the color photograph section has been retained.

Download or read book Trophic Cascades written by John Terborgh and published by Island Press. This book was released on 2013-06-25 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world’s leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world’s major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.
Download or read book The Captives of Abb s Valley written by James Moore and published by . This book was released on 2012-12 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: A tragedy of Virginian colonial frontier In the summer of 1786 a large war party of Shawnee Indians entered Abb's Valley, Virginia, and descended on the household of militia officer Captain John Moore which included members of his immediate family together with hired labourers. The family occupied a substantial log building and were well armed, so Moore believed that his family was well placed to fight off a small Indian attack. The nearest homestead was six miles away and Moore, relying on his own abilities, thought it unnecessary to follow the example of neighbours by taking refuge in the nearest fort. The attack achieved complete surprise and Moore was killed before he could reach the safety of the house. What followed was an appalling, but typical, Indian massacre of the colonial period frontier in the 18th century. Various family members, young and old, were slaughtered on the spot, the property was set alight and a substantial herd of livestock was taken. Surviving members of the Moore family were taken as captives to the Indian townships, several of them being murdered on the journey. Once the survivors reached the Indian village there followed another period of torture which for Mrs. Moore and a teenage daughter proved fatal. Two young women survived their ordeals to eventually be ransomed. The story of this notable frontier tragedy was written by James Moore, a son of Mary Moore, who was one of the two ransomed captives. This a vital account of the struggles endured by the early settlers of the American wilderness and will be of essential interest to anyone interested in the early history of the state of Virginia.

Download or read book Horticulture Plants for People and Places Volume 2 written by Geoffrey R. Dixon and published by Springer. This book was released on 2014-06-10 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Trilogy explains “What is Horticulture?”. Volume two of Horticulture: Plants for People and Places analyses in depth the scientific, managerial and ecological concepts which underpin Environmental Horticulture. Chapters describe: Horticulture and the Environment, Woody Ornamentals, Herbs and Pharmaceuticals, Urban Greening, Rural Trees, Urban Trees, Turfgrass Science, Interior and External Landscaping, Biodiversity, Climate Change and Organic Production. Each is written by leading international experts. Sustainable use of resources and careful conservation are critically essential for the continuation of life on this Planet. Achieving this is where horticulture, natural flora and fauna and the environment interact in achieving sustainable development. Horticulture is the fundamental partner of ecological and environmental science and provides an understanding of eco-system services. Live plant networks are essential for rural and urban life. They are integral parts of natural communities, the context of historic and modern architecture and a means for rejuvenating cities and uniting communities. Plants provide urban, peri-urban and rural employment, business and tourism opportunities, leisure, rest and relaxation. These facets of Environmental Horticulture are clearly described in this book.

Download or read book Biological Warfare Against Crops written by Simon M. Whitby and published by Palgrave MacMillan. This book was released on 2002-01-12 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until now little attention has been paid to the development of military capabilities designed to target food crops with biological warfare agents. This book represents the first substantive study of state-run activities in this field. It shows that all biological warfare programmes have included a component concerned with the development of anti-crop biological warfare agents and munitions. Current concern over the proliferation of biological weapons is placed in the context of the initiative to strengthen the Biological and Toxin Weapons Convention. The book concludes by arguing that the risks posed by this form of warfare can be minimised, but that this would depend largely on the effective and efficient implementation of regimes concerning the peaceful use and control of plant pathogens that pose a risk to human health and the environment.

Download or read book The Sugar Beet Crop written by D.A. Cooke and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 683 pages. Available in PDF, EPUB and Kindle. Book excerpt: D.A. Cooke and R.K. Scott Sugar beet is one of just two crops (the other being sugar cane) which constitute the only important sources of sucrose - a product with sweeten ing and preserving properties that make it a major component of, or additive to, a vast range of foods, beverages and pharmaceuticals. Sugar, as sucrose is almost invariably called, has been a valued compo nent of the human diet for thousands of years. For the great majority of that time the only source of pure sucrose was the sugar-cane plant, varieties of which are all species or hybrids within the genus Saccharum. The sugar-cane crop was, and is, restricted to tropical and subtropical regions, and until the eighteenth century the sugar produced from it was available in Europe only to the privileged few. However, the expansion of cane production, particularly in the Caribbean area, in the late seventeenth and the eighteenth centuries, and the new sugar-beet crop in Europe in the nineteenth century, meant that sugar became available to an increasing proportion of the world's population.
