In a very real sense, much of North American physiological plant ecol ogy began in the Basin and Range and has been researched there over the last four decades. However, we believe that this book may be the first attempt to bring together the full range of contemporary research into the fascinating plant biology of the Basin and Range Province. We have invited contributions from researchers presently working in and around the Province and asked them to review the major vegetation zones and distinctive environmental issues from a predominantly plant ecophysiological perspective. As researchers interested in plant physi ological and ecological processes, and in atmospheric processes affect ing vegetation, we have tended to emphasize the atmosphere, plant, soil continuum in structuring this book. After an introduction to the geography of the region, we deal with atmospheric processes and climates of the Great Basin, follow with chapters on the different vegetational zones, treated from ecophysiological perspectives, and then place emphasis on plant-soil relations. We have not treated plant animal interactions in the detail that the impacts of man and his domesticated animals on the desert ecosystem deserve. However we have included a review of a very promising technique (analysis of stable isotopes at natural abundance) for integration of these processes. We close with a compelling statement of the case for the Great Basin as a laboratory for climatic change research, prepared by a multidisciplinary team from the Desert Research Institute.

Due to many issues related to long-term carbon dynamics, an improved understanding of the biology of C4 photosynthesis is required by more than the traditional audience of crop scientists, plant physiologists, and plant ecologists. This work synthesizes the latest developments in C4 biochemistry, physiology, systematics, and ecology. The book concludes with chapters discussing the role of C4 plants in the future development of the biosphere, particularly their interactive effects on soil, hydrological, and atmospheric processes.

Many changessome discouraging, others hopefulhave occurred in the Rocky Mountain region since the first edition of this widely acclaimed book was published. Wildlife habitat has become more fragmented, once-abundant sage grouse are now scarce, and forest fires occur more frequently. At the same time, wolves have been successfully reintroduced, and new approaches to conservation have been adopted. For this updated and expanded Second Edition, the authors provide a highly readable synthesis of research undertaken in the past two decades and address two important questions: How can ecosystems be used so that future generations benefit from them as we have? How can we anticipate and adapt to climate changes while conserving biological diversity?

Fire Native Peoples and the Natural Landscape

For nearly two centuries, the creation myth for the United States imagined European settlers arriving on the shores of a vast, uncharted wilderness. Over the last two decades, however, a contrary vision has emerged, one which sees the country's roots not in a state of "pristine" nature but rather in a "human-modified landscape" over which native peoples exerted vast control.Fire, Native Peoples, and the Natural Landscape seeks a middle ground between those conflicting paradigms, offering a critical, research-based assessment of the role of Native Americans in modifying the landscapes of pre-European America. Contributors focus on the western United States and look at the question of fire regimes, the single human impact which could have altered the environment at a broad, landscape scale, and which could have been important in almost any part of the West. Each of the seven chapters is written by a different author about a different subregion of the West, evaluating the question of whether the fire regimes extant at the time of European contact were the product of natural factors or whether ignitions by Native Americans fundamentally changed those regimes.An introductory essay offers context for the regional chapters, and a concluding section compares results from the various regions and highlights patterns both common to the West as a whole and distinctive for various parts of the western states. The final section also relates the findings to policy questions concerning the management of natural areas, particularly on federal lands, and of the "naturalness" of the pre-European western landscape.

"The Great Basin, centering on Nevada and including substantial parts of California, Oregon, and Utah, gets its name from the fact that none of its rivers or streams flow to the sea. This book synthesizes the past 25,000 years of the natural history of this vast region. It explores the extinct animals that lived in the Great Basin during the Ice Age and recounts the rise and fall of the massive Ice Age lakes that existed here. It explains why trees once grew 13' beneath what is now the surface of Lake Tahoe, explores the nearly two dozen Great Basin mountain ranges that once held substantial glaciers, and tells the remarkable story of how pinyon pine came to cover some 17,000,000 acres of the Great Basin in the relatively recent past.These discussions culminate with the impressive history of the prehistoric people of the Great Basin, a history that shows how human societies dealt with nearly 13,000 years of climate change on this often-challenging landscape"--Provided by publisher.

Following a description of the physical and biological characterization of the four North American deserts together with the primary adaptations of plants to environmental stress, the authors go on to present case studies of key species. They provide an up-to-date and comprehensive review of the major patterns of adaptation in desert plants, with one chapter devoted to several important exotic plants that have invaded these deserts. The whole is rounded off with a synthesis of the resource requirements of desert plants and how they may respond to global climate change.

This book deals with arid and semi-arid environments and their classification, and the physiological restraints and adaptations of plants to the environment. Further, it discusses economic botany and the needs and methods of conserving economic plants. A broad view is taken regarding the definition of economic plants, taking into account their value to the environment as well as to man and to livestock. The individual deserts and associated semi-arid regions are described in separate chapters, providing background information on the regional environments in terms of climate and major plant formations. The economic plants within these formations, their usages, geographical distribution together with their morphological and physiological adaptations are treated in detail.
