The Biology Of Grasslands

This accessible text provides a concise but comprehensive introduction to the biology of global grasslands. Grasslands are vast in their extent, with native and non-native grasslands now covering approximately 50% of the global terrestrial environment. They are also of vital importance to humans, providing essential ecosystem services and some of the most important areas for the production of food and fibre worldwide. It has been estimated that 60% of calories consumed by humans originate from grasses, and most grain consumed is produced in areas that were formerly grasslands or wetlands. Grasslands are also important because they are used to raise forage for livestock, represent a source of biofuels, sequester vast amounts of carbon, provide urban green-space, and hold vast amounts of biodiversity. Intact grasslands contain an incredibly fascinating set of plants, animals, and microbes that have interested several generations of biologists, generating pivotal studies to important theoretical questions in ecology. As with other titles in the Biology of Habitats Series, the emphasis is on the organisms that dominate this environment although restoration, conservation, and experimental aspects are also considered.

This book is the most up to date and thorough account of the natural history of the plants that comprise the most important food crop on Earth, the grasses and grasslands.

More than forty percent of our country was once open prairie, grassland that extended from Missouri to Montana. Taking a critical look at this little-understood biome, award-winning journalist Richard Manning urges the reclamation of this land, showing how the grass is not only our last connection to the natural world, but also a vital link to our own prehistoric roots, our history, and our culture. Framing his book with the story of the remarkable elk, whose mysterious wanderings seem to reclaim his ancestral plains, Manning traces the expansion of America into what was then viewed as the American desert and considers our attempts over the last two hundred years to control unpredictable land through plowing, grazing, and landscaping. He introduces botanists and biologists who are restoring native grasses, literally follows the first herd of buffalo restored to the wild prairie, and even visits Ted Turner's progressive--and controversial--Montana ranch. In an exploration of the grasslands that is both sweeping and intimate, Manning shows us how we can successfully inhabit this and all landscapes.

Forgotten Grasslands of the South is the study of one of the biologically richest and most endangered ecosystems in North America. In a seamless blend of science and personal observation, renowned ecologist Reed Noss explains the natural history of southern grasslands, their origin and history, and the physical determinants of grassland distribution, including ecology, soils, landform, and hydrology. In addition to offering fascinating new information about these little-studied ecosystems, Noss demonstrates how natural history is central to the practice of conservation. Although theory and experimentation have recently dominated the field of ecology, ecologists are coming to realize how these distinct approaches are not divergent but complementary, and that pursuing them together can bring greater knowledge and understanding of how the natural world works and how we can best conserve it. This long-awaited work sets a new standard for scientific literature and is essential reading for those who study and work to conserve the grasslands of the South as well as for everyone who is fascinated by the natural world.

This volume is a result of the summary and synthesis of data collected in the Grassland Biome Program, which is part of the American contribution to the International Biological Program (IBP). The purpose of this volume is to present a summary of quantitative ecological investigations of North American grass lands and to present a set of broad comparisons of their characteristics and functions as well as the results of some models and experiments that lead to practical considerations of the management of grasslands. Synthesis is a continuing activity in science. Early in the Grassland Biome Program there was a synthesis of literature data on grasslands, edited by R. L. Dix and R. G. Beidleman (1969). Results of the first year of field data collection under this program were synthesized in a volume edited by N. R. French (1971). Development of the large-scale model constructed to depict the processes and the dynamics of state variables in grassland ecosystems was presented by Innis (1978). Soon to appear will be two volumes integrating studies of American grasslands with IBP studies in other grasslands of the world (Coupland, in press) and the application of systems analysis to understanding grassland function and utilization (Breymeyer and Van Dyne, in press). The present volume presents current results and comparisons of field investigations and experimental studies that were conducted under this program.

"This highly synthetic and scholarly work brings together new and important scientific contributions by leading experts on a rich diversity of topics concerning the history, ecology, and conservation of California's endangered grasslands. The editors and authors have succeeded admirably in drawing from a great wealth of recent research to produce a widely accessible and compelling, state-of-the-art treatment of this fascinating subject. Anyone interested in Californian biodiversity or grassland ecosystems in general will find this book to be an invaluable resource and a major inspiration for further research, management, and restoration efforts."—Bruce G. Baldwin, W. L. Jepson Professor and Curator, UC Berkeley "Grasses and grasslands are among the most important elements of the California landscape. This is their book, embodying the kind of integrated view needed for all ecological communities in California. Approaches ranging across an incredibly broad spectrum -- paleontology and human history; basic science and practical management techniques; systematics, community ecology, physiology, and genetics; physical factors such as water, soil nutrients, atmospherics, and fire; biological factors such as competition, symbiosis, and grazing -- are nicely tied together due to careful editorial work. This is an indispensable reference for everyone interested in the California environment."—Brent Mishler, Director of the University & Jepson Herbaria and Professor of Integrative Biology, UC Berkeley "The structure and function of California grasslands have intrigued ecologists for decades. The editors of this volume have assembled a comprehensive set of reviews by a group of outstanding authors on the natural history, structure, management, and restoration of this economically and ecologically important ecosystem."—Scott L. Collins, Professor of Biology, University of New Mexico
