Over a century ago, tall-grass prairie stretched over the most of what is now Iowa, Illinois, southern Minnesota, northern Missouri, the Dakotas, Nebraska, Kansas and Oklahoma. Today only a few scattered patches remain. The author traces the history of the prairie and examines grassland ecology.

This is the first volume in the Long-Term Ecological Research (LTER) Network Series. Established in 1980, the LTER program is exploring a wide variety of biomes characteristic of the United States and developing a baseline for ecosystem dynamics over long time periods and broad spatial scales. The volumes in this series will include both comprehensive reviews of research from particular sites and topical overviews which use data from many sites to examine important questions in ecology. This volume, which focuses on the Konza Prairie in northeastern Kansas, is a synthesis of over 15 years of research in pristine tallgrass prairie. It gives a comprehensive site description and summarizes the key long-term studies that form the basis for the Konza Prairie Long-Term Ecological Research Program. It then presents a synthesis of the many research areas involved and develops a foundation for future ecological studies in tallgrass prairie. With over 150 figures and tables, chapters that encompass microbial through landscape scales, and an emphasis on lessons learned from long-term studies, this volume provides a unique and comprehensive perspective on the structural and functional ecology of the grassland ecosystem that once covered most of central North America.

The engineering of plants has a long history on this continent. Fields, forests, orchards, and prairies are the result of repeated campaigns by amateurs, tradesmen, and scientists to introduce desirable plants, both American and foreign, while preventing growth of alien riff-raff. These horticulturists coaxed plants along in new environments and, through grafting and hybridizing, created new varieties. Over the last 250 years, their activities transformed the American landscape. "Horticulture" may bring to mind white-glove garden clubs and genteel lectures about growing better roses. But Philip J. Pauly wants us to think of horticulturalists as pioneer "biotechnologists," hacking their plants to create a landscape that reflects their ambitions and ideals. Those standards have shaped the look of suburban neighborhoods, city parks, and the "native" produce available in our supermarkets. In telling the histories of Concord grapes and Japanese cherry trees, the problem of the prairie and the war on the Medfly, Pauly hopes to provide a new understanding of not only how horticulture shaped the vegetation around us, but how it influenced our experiences of the native, the naturalized, and the alien--and how better to manage the landscapes around us.

Based on papers presented at a 1987 symposium, "Fire in North American Grasslands," cosponsored by the Ecological Society of America and the Botanical Society of America, this book represents an important contribution to key unanswered questions concerning the role of fire in grassland ecosystems: How often did fires occur in the past? Were they primarily natural or caused by humans? At what time of year did grasslands normally burn? How should fire be used as a management tool? What constitutes a proper prescribed burning regime both with and without grazing?

Ecosystem management has emerged in the past several years as the new paradigm for managing public and private land. It combines the principles of ecosystem-level ecology with the policy requirements of resource and public land management. This collection of selected readings will serve as an introduction to the concepts of biological diversity, ecological process, biotic integrity, and ecological sustainability that underlie ecosystem management.

Most environmental studies are based upon data collected at fine spatial scales plots, sediments, cores, etc.. Furthermore, temporal scales of these studies have been relatively short days, weeks, months and few studies have exceeded three years duration the typical funding cycle.; Despite this history, environmental scientists are now being called upon to extrapolate findings from "plot-level" studies to broader spatial scales and from short-term studies to longer temporal scales, up to decades for questions related to long-term processes such as global warming and the rise in sea level.; The complex questions being addressed internationally require that scientists take advantage of new technologies including remote sensing, geographic information systems GIS, and powerful climatic and environmental simulation models. As more environmental scientists begin to work at these broader spatial and temporal scales, and to utilize many of the newer technologies, they are recognising a whole new class of problems.; This book aims to address the most pertinent issues, and includes a comprehensive review of selected topics, case studies, and theoretical discussions, divided into seven sections each preceded by a brief introduction.
