Book Description
The analysis of vegetation history is one of the prime objectives for vegetation scientists. In order to understand the recent composition of local floras and plant communities a second knowledge of species com position during recent millenia is essential. With the present concern over climate changes, due to human activities, an understanding of past vegeta tion distribution becomes even more important, since the correlation between climate and vegetation can often be used to predict possible impacts to crops and forests. I was very fortunate to receive the help of Drs. Webb and Huntley to compile this volume on vegetation history. They have collated an impres sive set of papers which together give an account of the vegetation history of most of the continents during the late-Tertiary and Quaternery periods. There are, however, gaps in the coverage achieved, most notably Africa, and Asia apart from Japan. The information in this book will nonetheless certainly be used widely by vegetation scientists for the regions covered in the book and much of it has relevance to the areas not explicitly described. The authors of the individual chapters have done their best to cover recent topics of interest as well as established facts. It is intended that a separate volume will be produced in the near future covering the vegetation history of Africa and Asia. I thank the editors of It fits well into the this volume for their commendable achievement.

Book Description
From Coastal Wilderness to Fruited Plain is an account of the making of a large part of the American landscape following European settlement. Drawing upon land survey records and early travellers' accounts, Dr Whitney reconstructs the 'virgin' forests and grasslands of the north-eastern and central United States during the pre-settlement period. He then documents successively the clearance and fragmentation of the region's woodlands, the harvest of the forest and its game, the ploughing of the prairies, and the draining of wetlands. The degree to which these activities altered the soil, climate, plant and animal communities, and water cycle are evaluated, and the sustainability of present-day ecosystems is brought into question in this account.

Book Description
The papers in this volume were presented at the Geobotany Conference held at Bowling Green State University, Bowling Green, Ohio, on 21 February 1976. Though such diverse topics as anthropology and paleobotany are covered, all papers utilized the concept of geobotany as a unifying theme. Nearly a decade ago, the first in this series of geobotany conferences was organized on this campus by Dr. Jane Forsyth of the Department of Geology. After considerable growth, culminating in an International Geobotany Conference at the University of Tennessee in 1973, it was decided to again organize a regional geobotany meeting. The melange of papers in this volume are products of that meeting. Geobotany, by definition, is an interdiscip1inarian approach to interpretational problems involving such investigators as geologists and botanists, archaeologists and stratigraphers, ecologists and pa1yno1ogists. Interaction among these individuals is necessary for the satisfactory solution of a problem. Each can provide invaluable assistance to the other. The purpose of the meeting in Bowling Green was to provide a forum for the exchange of ideas and information. Sponsors of the conference include the Department of Biological Sciences, the Department of Geology, the Environmental Studies Center, the College of Arts and Sciences, and the Graduate School. All of the sponsors are academic or administrative units of Bowling Green State University and each played an important role in the success of the conference.

Book Description
Mark W. Schwartz Soon after we came into extensive meadows: and I was assured that those meadows continue for a hundred and fifty miles. being in winter drowned lands and marshes. By the dryness of the season they were now beautiful pastures, and here presented itself one of the most delightful prospects I have ever beheld; all low grounds being meadow, and without wood, and all of the high grounds being covered with trees and appearing like islands: the whole scene seemed an elysium. Capt. Thomas Morris. 1791 I am sitting in a 60-mile-an-hour bus sailing over a highway originally laid out for horse and buggy. The ribbon of concrete has been widened and widened until the field fences threaten to topple into the road cuts. In the narrow thread of sod between the shaved banks and the toppling fences grow the relics of what once was Illinois: the prairie.

Book Description
Riparian Landscapes examines the ecological systems of streamside and floodplain areas from the perspective of landscape ecology. The specific spatial pattern of riparian vegetation is seen as a result of, and a control on, the ecological, geomorphological, and hydrological processes that operate along rivers. Riparian structures are controlled by the spatial dynamics of channels, flooding and soil moisture. These dynamics are part of integrated cascades of water, sediment, nutrients and carbon, to which animal and plant species respond in ways that illuminate community structure and competition. The role of the riparian zone in controlling species distribution and abundance is discussed. Intelligent management of these valuable ecological resources is highlighted. The potential for linking hydrological, geomorphological and ecological simulation models is also explored. This book will be of interest to graduate and professional research workers in environmental science, ecology and physical geography.
