Book Description
Paleoclimatology: Reconstructing Climates of the Quaternary, Third Edition—winner of a 2015 Textbook Excellence Award (Texty) from The Text and Academic Authors Association—provides a thorough overview of the methods of paleoclimatic reconstruction and of the historical changes in climate during the past three million years. This thoroughly updated and revised edition systematically examines each type of proxy and elucidates the major attributes and the limitations of each. Paleoclimatology, Third Edition provides necessary context for those interested in understanding climate changes at present and how current trends in climate compare with changes that have occurred in the past. The text is richly illustrated and includes an extensive bibliography for further research. - Winner of a 2015 Texty Award from the Text and Academic Authors Association - A comprehensive overview of the methods of paleoclimate reconstruction, and the record of past changes in climate during the last ~3 million years - Addresses all the techniques used in paleoclimatic reconstruction from climate proxies - With full-color throughout, and thoroughly revised chapters on dating methods, climate forcing, ice cores, marine sediments, pollen analysis, dendroclimatology, and historical records - Includes new chapters on speleothems, loess, and lake sediments - More than 1,000 new references and 190 new figures - Essential reading for those interested in how present trends in climate compare with changes that have occurred in the past

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 emergence of landscape ecology during the 1980s represents an impor tant maturation of ecological theory. Once enamored with the conceptual beauty of well-balanced, homogeneous ecosystems, ecologists now assert that much of the essence of ecological systems lies in their lumpiness. Patches with differing properties and behaviors lie strewn across the land scape, products of the complex interactions of climate, disturbance, and biotic processes. It is the collective behavior of this patchwork of eco systems that drives pattern and process of the landscape. is not an end point This realization of the importance of patch dynamics in itself, however. Rather, it is a passage to a new conceptual framework, the internal workings of which remain obscure. The next tier of questions includes: What are the fundamental pieces that compose a landscape? How are these pieces bounded? To what extent do these boundaries influence communication and interaction among patches of the landscape? Will con sideration of the interactions among landscape elements help us to under stand the workings of landscapes? At the core of these questions lies the notion of the ecotone, a term with a lineage that even predates ecosystem. Late in the nineteenth century, F. E. Clements realized that the transition zones between plant communi ties had properties distinct from either of the adjacent communities. Not until the emergence of patch dynamics theory, however, has central signif icance of the ecotone concept become apparent.

Book Description
Students of human behavior have always been interested in the relationship between human populations and their environment. Decades of research not only have illuminated the backdrop against which culture is viewed, but have identi fied many of the conditions that influence or promote technological develop ment, social transformation, and economic reorganization. It has become in creaSingly evident, however, that if we are to explore more forcefully the linkages between culture and environment, a processual orientation is required. This is found in human ecology-the study of the relationship between people and the ecosystem of which they are a part. This book is a collection of papers about the recent and distant past by scientists and humanists involved in the study of human ecology in northeastern North America. The authors critically examine the systemic interface between people and their environment first by identifying the indicators of that rela tionship (e.g., historical documentation, archaeological site patterning, faunal remains), then by defining the processes by which change in one part of the ecosystem affects other parts (e.g., by conSidering how an ecotonal gradient affects biotic communities over time), and finally by explicating the behavioral implications thereof.

Book Description
'Succession' is the term used to describe the phenomenon of changes in vegetational types in both time and space. The subject of the colonization and exploitation of 'new' areas by plants is a key one in ecology and this book summarizes the theoretical arguments currently raging about the topic.

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
The environment consists of the surroundings in which an organism operates, including air, water, land, natural resources, flora, fauna, humans and their interrelation. It is this environment which is both so valuable, on the one hand, and so endangered on the other. And it is people which are by and large ruining the environment both for themselves and for all other organisms. This series covers leading-edge research in a cross-section of fields centring on the environment.
