Download or read book Weed Risk Assessment written by R. H. Groves and published by CSIRO PUBLISHING. This book was released on 2001 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of invasive species on native vegetation is a major threat to biodiversity all over the world - a threat ranked second only to habitat destruction. Other negative effects of weed invasions include reduced ecosystem services, loss to agricultural production and impacts on human health. This work covers the discipline of risk assessment as applied to the invasion ecology of plants. Taking a global context, it synthesizes theories on plant invasions, introduces a variety of models for weed risk assessment, and addresses procedures for ranking invasive species on a range of scales to determine weeds of national significance. It shows how the application of risk assessment to weed invasion may help reduce weed impact and thereby improve living conditions for people throughout the world. This text is aimed at invasions ecologists, botanists, quarantine officers, policy-makers and community groups wanting to know more about this developing discipline.

Download or read book Status of Pollinators in North America written by National Research Council and published by National Academies Press. This book was released on 2007-05-13 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.
Download or read book Conservation by Proxy written by Tim Caro and published by Island Press. This book was released on 2010-06-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.

Download or read book Food Safety Handbook written by Ronald H. Schmidt and published by John Wiley & Sons. This book was released on 2005-03-11 with total page 866 pages. Available in PDF, EPUB and Kindle. Book excerpt: As with the beginning of the twentieth century, when food safety standards and the therapeutic benefits of certain foods and supplements first caught the public’s attention, the dawn of the twenty-first century finds a great social priority placed on the science of food safety. Ronald Schmidt and Gary Rodrick’s Food Safety Handbook provides a single, comprehensive reference on all major food safety issues. This expansive volume covers current United States and international regulatory information, food safety in biotechnology, myriad food hazards, food safety surveillance, and risk prevention. Approaching food safety from retail, commercial, and institutional angles, this authoritative resource analyzes every step of the food production process, from processing and packaging to handling and distribution. The Handbook categorizes and defines real and perceived safety issues surrounding food, providing scientifically non-biased perspectives on issues for professional and general readers. Each part is divided into chapters, which are then organized into the following structure: Introduction and Definition of Issues; Background and Historical Significance; Scientific Basis and Implications; Regulatory, Industrial, and International Implications; and Current and Future Implications. Topics covered include: Risk assessment and epidemiology Biological, chemical, and physical hazards Control systems and intervention strategies for reducing risk or preventing food hazards, such as Hazard Analysis Critical Control Point (HACCP) Diet, health, and safety issues, with emphasis on food fortification, dietary supplements, and functional foods Worldwide food safety issues, including European Union perspectives on genetic modification Food and beverage processors, manufacturers, transporters, and government regulators will find the Food Safety Handbook to be the premier reference in its field.

Download or read book Public Health Consequences of E Cigarettes written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-05-18 with total page 775 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans use e-cigarettes. Despite their popularity, little is known about their health effects. Some suggest that e-cigarettes likely confer lower risk compared to combustible tobacco cigarettes, because they do not expose users to toxicants produced through combustion. Proponents of e-cigarette use also tout the potential benefits of e-cigarettes as devices that could help combustible tobacco cigarette smokers to quit and thereby reduce tobacco-related health risks. Others are concerned about the exposure to potentially toxic substances contained in e-cigarette emissions, especially in individuals who have never used tobacco products such as youth and young adults. Given their relatively recent introduction, there has been little time for a scientific body of evidence to develop on the health effects of e-cigarettes. Public Health Consequences of E-Cigarettes reviews and critically assesses the state of the emerging evidence about e-cigarettes and health. This report makes recommendations for the improvement of this research and highlights gaps that are a priority for future research.
