Beschreibung

Recent years have seen renewed interest in the fragile alpine biota. The International Year of Mountains in 2002 and numerous international programs and initiatives have contributed to this. Since nearly half of mankind depends on water supplies originating in mountain catchments, the integrity and functional signi?cance of the upland biota is a key to human welfare and will receive even more attention as water becomes an increasingly limited resource. Intact alpine vegetation,as the safeguard of the water towers of the world, is worth being well understood. This new edition of Alpine Plant Life is an update with over 100 new references,new diagrams, revised and extended chapters (particularly 7, 10, 11, 12, 16, 17) and now also offers a geographic index. My thanks go to the many careful readers of the ?rst edition for their most valuable comments, in parti- lar to Vicente I. Deltoro (Valencia) and Johanna Wagner (Innsbruck). Basel,April 2003 Christian Körner Preface to the ?rst edition One of the largest natural biological experiments, perhaps the only one replicated across all latitudes and all climatic regions,is uplift of the la- scape and exposure of organisms to dramatic climatic gradients over a very short distance, otherwise only seen over thousands ofkilometers of poleward traveling. Generations of plant scientists have been fascinated by these natural test areas,and have explored plant and ecosystem responses to alpine life conditions. Alpine Plant Life is an attempt at a synthesis.

Portrait

Christian Körner was born in 1949 in Salzburg, Austria, got his academic degrees from the University of Innsbruck, and became professor of botany at the University of Basel, Switzerland in 1989. He published over 300 scientific articles on plant-environment interactions and authored and coauthored numerous scientific books, including the leading plant science textbook Strasburger.

Pressestimmen

"The book may serve not only as an excellent reference source for ecophysiological topics, but also as a source of fresh ideas and inspiration for a much broader readership." (LeoS KlimeS, Folia Geobotanica, Vol. 41 (4), 2006)" ... the best modern treatment of "functional ecology" of alpine plants that I have seen. ... this new edition added over 100 new references, new diagrams and revised and extended several chapters. ... an excellent summary and key to the study of plant-habitat relationships. ... should be a compulsory reading for every plant ecologist. In my library it is right next to the Larcher's Physiological Plant Ecology." (Botanical Electronic News)"This is a fascinating synthesis on plant life at high altitude all around the world. There have been a number of studies on this topic, but the book by C. Körner is not just an addition to an already long list of publications. It attempts a synthesis based on a thorough functional analysis of the processes controlling plant life in these extreme situation, and on a broad overview of many of the mountain areaas around the world. ... It is also a very useful tool for ecophysiologists, because all the questions addressed are carefully analysed under the different relevant view points. ... In brief, this book is a model study for ecologists and ecophysiologists." (Annals of Forest Science)"Alpine Plant Life proved to be the right book for those who are either advanced gardeners or for those with scientific interests in the alpine ecosystems. This book is divided into 17 chapters beginning with the discussion of "Plant Ecology at High Elevations" and ending with an excellent discussion of "Global Change at High Elevation". ... Several color plates supplement the black and white photographs included throughout the book."

(Erwin Dreyer, Annals of Forest Science, Vol. 61(5), 2004)"... a welcome second edition. ...  It is a superb textbook - well written with plenty of good quality photographs, graphs and diagrams. It hits a happy compromise in being accessible to novices in upland areas and/or plants but with sufficient depth to leave the reader feeling that they have got to grips with the topic. The book starts with reviews of alpine life zones, climate, soils ... . A superb textbook that should be read and used by all ecology students."(Bulletin of the British Ecological Society, Vol. 35(1), 2004)
