Available in PDF, EPUB and Kindle. Book excerpt: Sound decisions about the use and conservation of natural resources require high-quality, independent scientific information accessible to all who need it. Provision of such information, particularly on the status and trends of the nation's biological resources, is central to the mission of the U.S. Geological Survey's (USGS) Biological Resources Division, formerly the National Biological Service (NBS). This report, The Status and Trends of the Nation's Biological Resources, is a major contribution to meeting the nation's need for better information about our nation's living resources. This two-volume book provides the first large-scale assessment of the health of the nation's plants, animals, and ecosystems and is intended for use by managers, scientists, policy makers, and the general public. It synthesizes existing and new information about birds, mammals, fishes, plants, and other species and summarizes what is known about the status and trends of major U.S. ecosystems. The findings reported here offer valuable insight into both successes and failures in resource management and point the way to better management of biological resources in the future.

Download or read book The American West at Risk written by Howard G. Wilshire and published by Oxford University Press. This book was released on 2008-06-05 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: The American West at Risk summarizes the dominant human-generated environmental challenges in the 11 contiguous arid western United States - America's legendary, even mythical, frontier. When discovered by European explorers and later settlers, the west boasted rich soils, bountiful fisheries, immense, dense forests, sparkling streams, untapped ore deposits, and oil bonanzas. It now faces depletion of many of these resources, and potentially serious threats to its few "renewable" resources. The importance of this story is that preserving lands has a central role for protecting air and water quality, and water supplies--and all support a healthy living environment. The idea that all life on earth is connected in a great chain of being, and that all life is connected to the physical earth in many obvious and subtle ways, is not some new-age fad, it is scientifically demonstrable. An understanding of earth processes, and the significance of their biological connections, is critical in shaping societal values so that national land use policies will conserve the earth and avoid the worst impacts of natural processes. These connections inevitably lead science into the murkier realms of political controversy and bureaucratic stasis. Most of the chapters in The American West at Risk focus on a human land use or activity that depletes resources and degrades environmental integrity of this resource-rich, but tender and slow-to-heal, western U.S. The activities include forest clearing for many purposes; farming and grazing; mining for aggregate, metals, and other materials; energy extraction and use; military training and weapons manufacturing and testing; road and utility transmission corridors; recreation; urbanization; and disposing of the wastes generated by everything that we do. We focus on how our land-degrading activities are connected to natural earth processes, which act to accelerate and spread the damages we inflict on the land.

Available in PDF, EPUB and Kindle. Book excerpt: The human love of novelty and desire to make one place look like another, coupled with massive increases in global trade and transport, are creating a growing economic and ecological threat. The same forces that are rapidly "McDonaldizing" the world's diverse cultures are also driving us toward an era of monotonous, weedy, and uniformly impoverished landscapes. Unique plant and animal communities are slowly succumbing to the world's "rats and rubbervines" -- animals like zebra mussels and feral pigs, and plants like kudzu and water hyacinth -- that, once moved into new territory, can disrupt human enterprise and well-being as well as native habitats and biodiversity. From songbird-eating snakes in Guam to cheatgrass in the Great Plains, "invasives" are wreaking havoc around the world. In A Plague of Rats and Rubbervines, widely published science writer Yvonne Baskin draws on extensive research to provide an engaging and authoritative overview of the problem of harmful invasive alien species. She takes the reader on a worldwide tour of grasslands, gardens, waterways, and forests, describing the troubles caused by exotic organisms that run amok in new settings and examining how commerce and travel on an increasingly connected planet are exacerbating this oldest of human-created problems. She offers examples of potential solutions and profiles dedicated individuals worldwide who are working tirelessly to protect the places and creatures they love. While our attention is quick to focus on purposeful attempts to disrupt our lives and economies by releasing harmful biological agents, we often ignore equally serious but much more insidious threats, those that we inadvertently cause by our own seemingly harmless actions. A Plague of Rats and Rubbervines takes a compelling look at this underappreciated problem and sets forth positive suggestions for what we as consumers, gardeners, travelers, nurserymen, fishermen, pet owners, business people -- indeed all of us who by our very local choices drive global commerce -- can do to help.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides an important collection of new research that sheds light on many aspects of the evolutionary patterns of gymnosperms, angiosperms, and pteridophtes. The book includes a complete chloroplast genome sequence study and describes a method that induces the systemic silencing of target genes in the Ceratopteris gametophyte. It presents a study of how herbicide treatments reduce fern densities and create the establishment of regeneration. It also analyzes an EST dataset from G. biloba that reveals genes potentially unique to gymnosperms and includes a study of episodic rate acceleration in the ancestral grasses.

Available in PDF, EPUB and Kindle. Book excerpt: In 1953, birding guru Roger Tory Peterson and noted British naturalist James Fisher set out on what became a legendary journey-a one hundred day trek over 30,000 miles around North America. They traveled from Newfoundland to Florida, deep into the heart of Mexico, through the Southwest, the Pacific Northwest, and into Alaska's Pribilof Islands. Two years later, Wild America, their classic account of the trip, was published. On the eve of that book's fiftieth anniversary, naturalist Scott Weidensaul retraces Peterson and Fisher's steps to tell the story of wild America today. How has the continent's natural landscape changed over the past fifty years? How have the wildlife, the rivers, and the rugged, untouched terrain fared? The journey takes Weidensaul to the coastal communities of Newfoundland, where he examines the devastating impact of the Atlantic cod fishery's collapse on the ecosystem; to Florida, where he charts the virtual extinction of the great wading bird colonies that Peterson and Fisher once documented; to the Mexican tropics of Xilitla, which have become a growing center of ecotourism since Fisher and Peterson's exposition. And perhaps most surprising of all, Weidensaul finds that much of what Peterson and Fisher discovered remains untouched by the industrial developments of the last fifty years. Poised to become a classic in its own right, Return to Wild America is a sweeping survey of the natural soul of North America today.
