A new vision is sweeping through ecological science: The dense web of dependencies that makes up an ecosystem has gained an added dimension-the dimension of time. Every field, forest, and park is full of living organisms adapted for relationships with creatures that are now extinct. In a vivid narrative, Connie Barlow shows how the idea of "missing partners" in nature evolved from isolated, curious examples into an idea that is transforming how ecologists understand the entire flora and fauna of the Americas. This fascinating book will enrich and deepen the experience of anyone who enjoys a stroll through the woods or even down an urban sidewalk. But this knowledge has a dark side too: Barlow's "ghost stories" teach us that the ripples of biodiversity loss around us now are just the leading edge of what may well become perilous cascades of extinction.
Abundantly illustrated with more than 400 color photographs and 200 detailed drawings, this comprehensive guide to the state's rare and endangered plants provides photographs and botanical illustrations in a single volume formatted for field use. More than 200 species are covered, including two dozen that are federally listed and 170-plus that are listed as Threatened, Endangered, Rare, or of Special Concern by the Georgia Department of Natural Resources. The guide is designed for easy, nontechnical identification of species in the field. Color photographs show the plants in their natural surroundings, and drawings emphasize the most distinctive parts of the plants. Packed with information about the plants as well as their habitats and management, the guide facilitates the quick recognition of rare species, encourages awareness of their distribution and ecological significance, and provides guidelines for ensuring their survival. Additional features include directions for using the guide, a map of Georgia's counties, descriptions of the natural communities of Georgia, references for further reading, a glossary of frequently used terms, and indexes of scientific and common plant names. The guide also includes a chapter by Jennifer Ceska and University of Georgia horticulture professor James Affolter, founding members of the Georgia Plant Conservation Alliance, on horticultural requirements of rare species and the role of GPCA in their protection. This is a valuable resource for students, wildflower enthusiasts, botanists, land managers, and environmental decision makers. Each species account includes: one or more full-color photographs Georgia distribution map line drawing emphasizing such key field identification characters as leaf, stem, flower, and fruit scientific and common names legal and wetland status brief nontechnical description emphasizing key field identification characters flowering, fruiting, or sporulation period description of species habitat information on best survey season range-wide distribution Georgia conservation status management guidelines information on similar species and related rare species list of references
In the United States and Canada, thousands of species of native plants are edging toward the brink of extinction, and they are doing so quietly. They are slipping away inconspicuously from settings as diverse as backyards and protected lands. The factors that have contributed to their disappearance are varied and complex, but the consequences of their loss are immeasurable. With extensive histories of a cast of familiar and rare North American plants, The Quiet Extinction explores the reasons why many of our native plants are disappearing. Curious minds will find a desperate struggle for existence waged by these plants and discover the great environmental impacts that could come if the struggle continues. Kara Rogers relates the stories of some of North America’s most inspiring rare and threatened plants. She explores, as never before, their significance to the continent’s natural heritage, capturing the excitement of their discovery, the tragedy that has come to define their existence, and the remarkable efforts underway to save them. Accompanied by illustrations created by the author and packed with absorbing detail, The Quiet Extinction offers a compelling and refreshing perspective of rare and threatened plants and their relationship with the land and its people.
Essays link Gaian science to such global environmental quandaries as climate change and biodiversity destruction, providing perspectives from science, philosophy, politics, and technology.
This book contains the proceedings of a symposium held at the College of Charleston, Charleston, South Carolina, USA, 16-20 June 1986. The seed for this symposium arose from a group of physiologists , soU scientists and biochemists that met in Leningrad, USSR in July 1975 at the 12th Botanical Conference in a Session organized by Professor B.B. Vartepetian. This group and others later conspired to contribute to a book entitled Plant Life in Anaerobic Environments (eds. D. D. Hook and R. M. M. Crawford, Ann Arbor Science, 1978). Several contributors to the book suggested in 1983 that a broad-scoped symposium on wetlands would be useful (a) in facilitating communication among the diverse research groups involved in wetlands research (b) in bringing researchers and managers together and (c) in presenting a com prehensive and balanced coverage on the status of ecology ami management of wetlands from a global perspective. With this encouragement, the senior editor organized a Plan ning Committee that encompassed expertise from many disciplines of wetland scientists and managers. This Committee, with input from their colleagues around the world, organized a symposium that addressed almost every aspect of wetland ecology and management.
