Book Description
This book represents a rather complicated history of encounters, changes in research interest and some very interesting results. Initially it is the very fruitful interaction of Ecology and Geology. The point of view of ecologists is extremely refreshing for hard science people. Interaction and inter-relationships are the focus of Ecology whereas the traditional sciences, such as Geology, have tried to isolate the natural phenomena so that thye could be studied in a more rigorous manner. The traditional sciences were of course natural science – based since the world to be observed was at the door step of everyone, mountains, weather patterns, plants and so forth. Chemistry and Physics were de ned after Mathematics in order to establish more precise and viable principles of the behavior of the materials that formed the world around mankind. It became quite clear that the observation of the natural world was too complicated to consider all of the possible variables which could affect an observed process or situation. The systems were simpli ed and taken into the laboratory in order to better master the phenomena observed. Physics c- cerned itself with non-reacting materials, subjected to essentially mechanical forces.

Book Description
This book by soil scientists and ecologists reviews how and why plants influence soils. Topics include effects on mineral weathering, soil structure, and soil organic matter and nutrient dynamics, case studies of soil-plant interactions in specific biomes and of secondary chemicals influencing nutrient cycling, the rhizosphere, and potential evolutionary consequences of plant-induced soil changes. This is the first volume that specifically highlights the effects of plants on soils and their feedbacks to plants. By contrast, other texts on soil-plant relationships emphasize effects of soil fertility on plants, following the strongly agronomic character of most research in this area. The aspects discussed in this volume are crucial for understanding terrestrial ecosystems, biogeochemistry and soil genesis. The book is directed to terrestrial ecologists, foresters, soil scientists, environmental scientists and biogeochemists, and to students following specialist courses in these fields.

Book Description
The legal aspects of the influence of vegetation on the swelling and shrinking of clays, patterns of soil drying and moisture deficit in the vicinity of trees on clay soils, and evapo-transpiration and heaving clays in South Africa, are just some of the issues discussed in these papers.

Book Description
Of huge relevance in a number of fields, this is a survey of the different processes of soil clay mineral formation and the consequences of these processes concerning the soil ecosystem, especially plant and mineral. Two independent systems form soil materials. The first is the interaction of rocks and water, unstable minerals adjusting to surface conditions. The second is the interaction of the biosphere with clays in the upper parts of alteration profiles.

Book Description
This book is about ideas on the nature and causes of temporal change in the species composition of vegetation. In particular it examines the diverse processes of inter action of plants with their environment, and with one another, through which the species composition of vegetation becomes established. The first chapter considers the general nature of vegetation and the ways in which vegetation change is perceived by ecologists. Chapters 2 and 3 provide essential background about the relationships between plants and their abiotic and biotic environment. Anyone who is familiar with the fundamentals of plant ecology may prefer to pass over Chapters 2 and 3 which, of necessity, cover their subject matter very briefly. Sequences of development of vegetation on new volcanic rocks, sand dunes and glacial deposits, respectively, are outlined in Chapters 4, 5 and 6. Chapter 7 is about the patterns of vegetation change which occur in severe habitats around the world, and Chapter 8 discusses wetlands. Chapter 9 discusses the diverse responses of temperate forests to a variety of disturbing influences, and Chapter 10 deals with change in the species-rich forests of the Tropics. Chapter 11 treats, in detail, the empirical and inferential data on the biological processes occurring during vegetation change sequences. Chapter 12 considers the plant community phenomena which are implicated in the development of theory about vegetation change. The final chapter, Chapter 13, draws the diverse themes together into a unified theoretical structure by which the vegetation change phenomena may be understood.

Book Description
This new edition of the definitive work on doing paleoethnobotany brings the book up to date by incorporating new methods and examples of research, while preserving the overall organization and approach of the book to facilitate its use as a textbook. In addition to updates on the comprehensive discussions of macroremains, pollen, and phytoliths, this edition includes a chapter on starch analysis, the newest tool in the paleoethnobotanist's research kit. Other highlights include updated case studies; expanded discussions of deposition and preservation of archaeobotanical remains; updated historical overviews; new and updated techniques and approaches, including insights from experimental and ethnoarchaeological studies; and a current listing of electronic resources. Extensively illustrated, this will be the standard work on paleoethnobotany for a generation.
