Relicts of a Beautiful Sea

Relicts of a Beautiful Sea PDF Author: Christopher Norment
Publisher: UNC Press Books
ISBN: 1469618672
Category : Nature
Languages : en
Pages : 284

Book Description
Along a tiny spring in a narrow canyon near Death Valley, seemingly against all odds, an Inyo Mountain slender salamander makes its home. "The desert," writes conservation biologist Christopher Norment, "is defined by the absence of water, and yet in the desert there is water enough, if you live properly." Relicts of a Beautiful Sea explores the existence of rare, unexpected, and sublime desert creatures such as the black toad and four pupfishes unique to the desert West. All are anomalies: amphibians and fish, dependent upon aquatic habitats, yet living in one of the driest places on earth, where precipitation averages less than four inches per year. In this climate of extremes, beset by conflicts over water rights, each species illustrates the work of natural selection and the importance of conservation. This is also a story of persistence--for as much as ten million years--amid the changing landscape of western North America. By telling the story of these creatures, Norment illustrates the beauty of evolution and explores ethical and practical issues of conservation: what is a four-inch-long salamander worth, hidden away in the heat-blasted canyons of the Inyo Mountains, and what would the cost of its extinction be? What is any lonely and besieged species worth, and why should we care?

Groundwater Depletion in the United States (1900?2008)

Book Description
A natural consequence of groundwater withdrawals is the removal of water from subsurface storage, but the overall rates and magnitude of groundwater depletion in the United States are not well characterized. This study evaluates long- term cumulative depletion volumes in 40 separate aquifers or areas and one land use category in the United States, bringing together information from the literature and from new analy- ses. Depletion is directly calculated using calibrated ground- water models, analytical approaches, or volumetric budget analyses for multiple aquifer systems. Estimated groundwater depletion in the United States during 1900-2008 totals approx- imately 1,000 cubic kilometers (km3). Furthermore, the rate of groundwater depletion has increased markedly since about 1950, with maximum rates occurring during the most recent period (2000-2008) when the depletion rate averaged almost 25 km3 per year (compared to 9.2 km3 per year averaged over the 1900-2008 timeframe).
