Download or read book Biological Invasions in South Africa written by Brian W. van Wilgen and published by Springer Nature. This book was released on 2020-03-10 with total page 972 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.
Download or read book CYCADS WORLD ED 2E written by Jones Dl. and published by Smithsonian. This book was released on 2002-09-17 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cycads superficially resemble palms and are often misidentified as such. However, cycads are actually a unique assemblage of primitive plants that have been around for at least 250 million years. They have become highly sought after for gardens, both private and public, and their present status as endangered plants has engendered an upsurge of interest in their conservation. With Cycads of the World, David Jones has achieved that difficult task of writing a scientifically accurate text, which is both easy to read and to understand. For this second edition David Jones has added information covering over 100 new species and subspecies of cycads, and updated his material on the 200 species from the first edition. Each entry includes a full description, distribution and habitat information, and a detailed cultivation and propagation guide. Over 360 color photographs plus many other illustrations and maps facilitate easy identification for all living species. This second edition of Cycads of the World makes a fine addition to the library of anyone interested in exotic plants, including gardeners, landscape architects, horticulturalists, botanists, and the curious reader alike.

Download or read book Cycads written by John Sydney Donaldson and published by World Conservation Union. This book was released on 2003 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IUCN/SSC Cycad ACtion Plan brings together the best available information on this ancient and fascinating group of plants. Cycads were a dominant part of the earth's flora during the age of the dinosaurs and many species were common even in more recent times. However, many of the 297 species and subspecies dealt with in the Cycad Action Plan have been badly affected by habitat destruction and plant collecting within the last century. As a result, more than half the known species are now classified as threatened, and the cycads stand out as one of the most threatened groups of plants in this world.The Action Plan provides an overview of all the cycads and the threats to their survival. This is followed by separate assessments for the four broad regions where cycads now occur, namely Africa and the Indian Ocean Islands, Australia, Asia, and the New World. Trade in cycads has had a substantial impact on wild cycad populations and there is a separate chapter on trade and the effectiveness of control measures such as CITES. In addition, with so many species facing extinction in the wild, garden collections have become increasingly important and we have assessed the global status of cycad collections.Finally, the Cycad Action Plan presents a set of objectives and actions to reduce the threat to cycads in the wild and to provide ex situ conservation for those that almost certainly will become extinct in the wild. Wherever possible, we have tried to identify and build on innovative projects, such as community-based nurseries, and to link cycad consideration with other global and local initiatives such as the conservation of biodiversity hotspots.

Download or read book Behavioral Measures of Neurotoxicity written by National Research Council and published by National Academies Press. This book was released on 1990-02-01 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposure to toxic chemicalsâ€"in the workplace and at homeâ€"is increasing every day. Human behavior can be affected by such exposure and can give important clues that a person or population is in danger. If we can understand the mechanisms of these changes, we can develop better ways of testing for toxic chemical exposure and, most important, better prevention programs. This volume explores the emerging field of neurobehavioral toxicology and the potential of behavior studies as a noninvasive and economical means for risk assessment and monitoring. Pioneers in this field explore its promise for detecting environmental toxins, protecting us from exposure, and treating those who are exposed.
Download or read book Cactus and Succulent Plants written by Sara Oldfield and published by World Conservation Union. This book was released on 1997-01 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Found in a variety of forms, cacti and other succulents have elicited widespread interest and tremendous popularity worldwide. Although the subject of a certain amount of debate, about 10,000 species are recognized as belonging to the succulent group. Of these, an estimated 2,000 are threatened with global extinction in the wild and many more are regionally or nationally threatened mainly due to habitat destruction and collection for international trade.This Action Plan brings together from around the world current information on population status, threats and conservation of this particularly important group of plants. Prepared with conservationists, scientists, governments, protected area managers and grant-awarding bodies in mind, it suggests priorities for action and encourages collaboration among interested parties at all levels.
Download or read book The North American Model of Wildlife Conservation written by Shane P. Mahoney and published by JHU Press. This book was released on 2019-09-10 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: The foremost experts on the North American Model of Wildlife Conservation come together to discuss its role in the rescue, recovery, and future of our wildlife resources. At the end of the nineteenth century, North America suffered a catastrophic loss of wildlife driven by unbridled resource extraction, market hunting, and unrelenting subsistence killing. This crisis led powerful political forces in the United States and Canada to collaborate in the hopes of reversing the process, not merely halting the extinctions but returning wildlife to abundance. While there was great understanding of how to manage wildlife in Europe, where wildlife management was an old, mature profession, Continental methods depended on social values often unacceptable to North Americans. Even Canada, a loyal colony of England, abandoned wildlife management as practiced in the mother country and joined forces with like-minded Americans to develop a revolutionary system of wildlife conservation. In time, and surviving the close scrutiny and hard ongoing debate of open, democratic societies, this series of conservation practices became known as the North American Model of Wildlife Conservation. In this book, editors Shane P. Mahoney and Valerius Geist, both leading authorities on the North American Model, bring together their expert colleagues to provide a comprehensive overview of the origins, achievements, and shortcomings of this highly successful conservation approach. This volume • reviews the emergence of conservation in late nineteenth–early twentieth century North America • provides detailed explorations of the Model's institutions, principles, laws, and policies • places the Model within ecological, cultural, and socioeconomic contexts • describes the many economic, social, and cultural benefits of wildlife restoration and management • addresses the Model's challenges and limitations while pointing to emerging opportunities for increasing inclusivity and optimizing implementation Studying the North American experience offers insight into how institutionalizing policies and laws while incentivizing citizen engagement can result in a resilient framework for conservation. Written for wildlife professionals, researchers, and students, this book explores the factors that helped fashion an enduring conservation system, one that has not only rescued, recovered, and sustainably utilized wildlife for over a century, but that has also advanced a significant economic driver and a greater scientific understanding of wildlife ecology.
