Packrat Middens
Over the past thirty years, late Quaternary environments in the arid interior of western North America have been revealed by a unique source of fossils: well-preserved fragments of plants and animals accumulated locally by packrats and quite often encased, amberlike, in large masses of crystallized urine. These packrat middens are ubiquitous in caves and rock crevices throughout the arid West, where they can lie preserved for tens of thousands of years. More than a thousand of these deposits have been dated and analyzed, and middens have supplanted pollen records as a touchstone for studying vegetation dynamics and climatic change in radiocarbon time (the last 40,000 years). Now, similar dep...
Leaving Mesa Verde
It is one of the great mysteries in the archaeology of the Americas: the depopulation of the northern Southwest in the late thirteenth-century AD. Considering the numbers of people affected, the distances moved, the permanence of the departures, the severity of the surrounding conditions, and the human suffering and culture change that accompanied them, the abrupt conclusion to the farming way of life in this region is one of the greatest disruptions in recorded history. Much new paleoenvironmental data, and a great deal of archaeological survey and excavation, permit the fifteen scientists represented here much greater precision in determining the timing of the depopulation, the number of p...
A Great Aridness
With its soaring azure sky and stark landscapes, the American Southwest is one of the most hauntingly beautiful regions on earth. Yet staggering population growth, combined with the intensifying effects of climate change, is driving the oasis-based society close to the brink of a Dust-Bowl-scale catastrophe. In A Great Aridness, William deBuys paints a compelling picture of what the Southwest might look like when the heat turns up and the water runs out. This semi-arid land, vulnerable to water shortages, rising temperatures, wildfires, and a host of other environmental challenges, is poised to bear the heaviest consequences of global environmental change in the United States. Examining inte...
El Fin del Mundo
In a remote desert corner of Sonora, Mexico, the site of El Fin del Mundo offers the first recorded evidence of Paleoindian interactions with gomphotheres, an extinct species related to elephants. The Clovis occupation of North America is the oldest generally accepted and well-documented archaeological assemblage on the continent. This site in Sonora, Mexico, is the northernmost dated late Pleistocene gomphothere and the youngest in North America. It is the first documented intact buried Clovis site outside of the United States, the first in situ Paleoindian site in northwestern Mexico, and the first documented evidence of Clovis gomphothere hunting in North America. The site also includes a...
The Nature of Desert Nature
In this refreshing collection, one of our best writers on desert places, Gary Paul Nabhan, challenges traditional notions of the desert. Beautiful, reflective, and at times humorous, Nabhan’s extended essay also called “The Nature of Desert Nature” reveals the complexity of what a desert is and can be. He passionately writes about what it is like to visit a desert and what living in a desert looks like when viewed through a new frame, turning age-old notions of the desert on their heads. Nabhan invites a prism of voices—friends, colleagues, and advisors from his more than four decades of study of deserts—to bring their own perspectives. Scientists, artists, desert contemplatives, p...
Birds of the Sun
"The multiple, vivid colors of scarlet macaws and their ability to mimic human speech are key reasons they were and are significant to the Native peoples of the southwestern U.S. and northwest New Mexico. Although the birds' natural habitat is the tropical forests of Mexico and Central America, they were present at multiple archaeological sites in the region. Leading experts in southwestern archaeology explore the reasons why"--
Ecology and Biogeography of Pinus
A comprehensive review essential for all involved in the management of natural and planted pine forests.
Kenya's Changing Landscape
Botanist Homer L. Shantz took photographs of the Kenyan landscape in the early 1920s as part of his effort to document the natural plant cover of Africa. He returned there with B. L. Turner in the late 1950s to repeat the photographs. In 1990, Raymond Turner traveled to Kenya under the auspices of the National Geographic Society in order to match the photographs made by Shantz and B.L. Turner and to show the changes that have occurred over the decades since Shantz's initial journey. Turner's comparative photos and research into the botanical record dramatically reflect the encroachment of woody plants in arid areas and the increasing human impact in more humid locales. Turner's discussions of the photographs and the conclusions he draws provide an important reference for ecologists, geographers, botanists, and other researchers attempting similar studies. By documenting vegetation change in a region broadly similar climatically to North America's subtropical deserts and grasslands but different in its wildlife and its human culture, the book shows that the endpoints of landscape status are similar despite the vastly different histories of these two regions of the world.
The Applications and Limitations of Taxonomy (in Classification of Organisms)
Collects articles that discuss what taxonomy is, and how it is important in the field of biology regarding the classification of organisms.
Understanding Multiple Environmental Stresses
The research of the last decade has demonstrated that ecosystems and human systems are influenced by multiple factors, including climate, land use, and the by-products of resource use. Understanding the net impact of a suite of simultaneously occurring environmental changes is essential for developing effective response strategies. Using case studies on drought and a wide range of atmosphere-ecosystem interactions, a workshop was held in September 2005 to gather different perspectives on multiple stress scenarios. The overarching lesson of the workshop is that society will require new and improved strategies for coping with multiple stresses and their impacts on natural socioeconomic systems...
