The present volume, Nr. 5 in the T:VS series is an example of a handbook volume for working in vegetation science. Anyone working and teaching in this field knows the difficulties in obtaining basic environmental da ta needed for research and interpretation. There are regional publications and there are other data sets availa ble. In both cases the distribution is limited. The present volume by Dr. Muller intends to provide a selection of climatic parameters as they are commonly needed for the work of the vegetation scientist. The same set of monthly mean values are provided for about 1000 stations distributed as evenly as possible over the global land surfaces. The tabular presentation of data from the individual stations is put into a geographical context through va rious means. Climatological classifications according to KOPPEN/GEIGER and TROLL/PAFFEN are inclu ded as well as a revised system of climate diagrams from WALTER and LlETH. In the present form the glo bal standard climate data set should prove to be useful for vegetation science, biometeorology, agriculture, and forestry as well as general geography. I have to thank Dr. Muller for providing this valuable work to the T:VS series. I am sure that this selection of climatic data for the special needs of vegetation scientists will help many colleagues in different parts of the world.

Only a few laboratories in the world have taken the bold step to attempt the integration of sub-models of the climate system, the global biogeochemical cycles and the human/societal components. This volume reports such a major undertaking and it is an important step towards an integrated approach to global change science. The IMAGE 2 model is important in demonstrating our current ability to model the complex global system.

This fully-revised comprehensive fourth edition covers the whole field of physical geography including climate and atmosphere, geomorphology, biogeography, hydrology, oceans, Quaternary, environmental change, soils, remote sensing and GIS. This new edition reflects developments in the discipline during the last decade, with the expert advisory group providing an international perspective on the discipline of physical geography. Over 2000 entries that are self-contained or cross-referenced include 200 that are new to this edition, over 400 that are rewritten and updated, and new supporting references and additional recommended reading in many others. Entries removed from the last edition are available in the online resource. This volume is the essential reference point for students of physical geography and related environmental disciplines, lecturers and interested individuals alike.

Grasses: Systematics and Evolution is a selection of the very best papers from the Proceedings of the Third International Symposium on Grass Systematics and Evolution held in Sydney, Australia in 1998. The papers represent some of the leading work from around the world on grasses and include reviews and current research into the comparative biology and classification. All 41 papers have been peer-reviewed and edited.

The biological effects of global warming should be of concern to all thinking individuals, for warming could cause profound disruption of natural ecosystems and could threaten many species with extinction. This important book--the first to discuss in detail the consequences of global warming for ecosystems--includes commentary by distinguished scientists on many aspects of this critical problem. Experts describe responses of animals and plants to previous climate changes, interactions between various environmental components (precipitation and soil chemistry, for example), and synergisms between climate change and human activities such as deforestation. They consider many specific ecosystems, including tropical forests, the deciduous forests of eastern North America, the forests of the Pacific Northwest, Mediterranean-type ecosystems in California, arctic tundra, and arctic marine systems. Offering discussions that are both factual and speculative, the volume points the way to future investigations of the implications of global warming.
