Paleobotany has enormously expanded the documentation of fossil plant groups, floras and vegetation types, supporting its conclusions by technically much improved analyses of microfossils (pollen) and anatomical details. An increasing quantity and quality of all these informations from the geosciences is available when we follow the history of the biosphere up to the present. Simultaneously, research from the biosciences on the morphology, ecology, distribution, systematics and evolution of extant vascular plants, and on the ecogeographical differentiation of the vegetation cover of our planet, has made enormous progress. Thus, a synthetic geo- and bioscientific approach becomes more and more feasible and urgent for further advances in the many problems of common concern. A symposium organized by the "Deutsche Akademie der Naturforscher LEOPOLDINA", attractive to paleo- and neobotanists, stimulated the discussion between specialists of the two disciplines. The main results of the symposium are now presented in this volume: Sixteen international contributions outline the current knowledge about the historical differentiation and evolution of woody plant groups and forests, covering the whole biosphere. This survey, from the beginning of the Tertiary up to the present, is a first systhesis of relevant data from the geo- and biosciences.

This book summarizes the taxonomic details of selected fossil angiosperm pollen genera and species along with their affinity and occurrences in space and time. It provides information about the historical background of palynology from Palaeogene and Neogene sediments in India, general pollen morphology along with the terms commonly used in describing fossil angiosperm pollen and an overview of the Indian Tertiary sediments. A complete list of genera described in this book is given. It also includes a key for identification of Indian angiosperm genera as well as a description of selected fossil angiosperm pollen from India along with their Indian records, illustrations, locality, age and horizon from where these have been reported. In all 130 genera and 402 species have been dealt with. The names of genera and species are arranged alphabetically. The Discussion part includes a summarized account of palynofloras, their biostratigraphic application in various regions of India and their palaeogeographical and palaeoclimatic implications.
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.
Climate models show that climate change is not a uniform process. Areas of increased temperature are situated near areas of decreased temperature, areas with increased precipitation adjoin areas of drought. This is one of the reasons why climate change is so difficult to detect. Any parameter must be considered and tested locally or regionally and not on an average globally. This book gives an overview of current research methods and results in the different fields of climate research including modelling. In addition, it contains a hemisphere-wide stratigraphic data base with about 80000 species. All paleoclimatic data as well as a state-of-the-art atmospheric circulation model in a PC version are included. So both research and graduate teaching are supported with high-end software running on affordable computers, also in those countries that have no access to Cray super computers. Thus, this book will be of interest to all researchers and scientists in the field of climatology.
