Von Okosystemen und der Rolle des Menschen in ihnen sprechen heute
lournalisten, Politiker und viele andere Nicht-Biologen, denen noch
vor wenigen lahren selbst die Okologie - die Wissenschaft von den
Umweltbe- ziehungen der Lebewesen - kaum ein Begriff war. Wem die
Bedrohung unserer menschlichen Umwelt und ihr Einbezogensein in
natiirliche Regulations- systeme bewuBt wurde, dem konnen solche
Systeme und ihre Erforschung nicht mehr gleichgiiltig sein. Ihm
leuchtet auch ein, daB ohne Kenntnis "gesunder", im Gleichgewicht
befindlicher Okosysteme keine Heilung "kranker", aus dem
Gleichgewicht geratener, moglich ist. Aber was ist ein Okosystem?
Was bedeutet sein Gleichgewicht? Wie funktioniert es und was
leistet es? Solche Fragen beantwortet heute kaum ein Lexikon und
nur selten ein Lehrbuch, und wenn, dann an untergeordneter Stelle.
Es ist daher sehr zu begrtiBen, daB sich der Springer-Verlag
bereitfand, einen Sammelband herauszugeben, der ganz der
Okosystemforschung gewidmet ist. In diesem Bande wird zunachst
versucht, einen Uberblick tiber die Begriffe und die verschiedenen
Richtungen in der Okosystemforschung sowie tiber ihren derzeitigen
Stand zu geben. Als Beispiele werden sodann einzelne Fragen-
komplexe von verschiedenen Autoren eingehend dargestellt. Die
Auswahl dieser Beispie1e ergab sich aus dem Programm einer Tagung
der Deutschen Botanischen Gesellschaft, die im Juti 1971 in
Innsbruck stattfand. "Okosystem- forschung" war hier zum ersten Mal
Rahmenthema fiir einen ganzen Vortrags- tag. Aus dem anschlieBenden
zweitagigen Symposium tiber "Stoffproduktion", das von der
Gesellschaft fUr Angewandte Botanik veranstaltet wurde, stammen
einige weitere Beitrage, die auf die Primarproduktion, d. h. auf
den grund- legenden Energiegewinn der Okosysteme, ausgerichtet
sind.
This book was written 30 years ago as the first synthesis of
European and Anglo-American methods in vegetation ecology. Upon its
publication in 1974, it rapidly became the standard text for the
study of vegetation in over 60 US colleges and universities. An
unsolicited review appeared in Ecology 56: 1233 (1975) with the
title "Getting It All Together in Plant Synecology." The book also
received wide international acceptance. "In his foreword to the
1974 edition, Raymond Fosberg referred to this book as 'by far the
best work of its scope that I know.' It is still agreed that there
is no comparable work. It was used as the only textbook for the
first twenty offerings of one graduate course. For the past dozen
years it's been moved to the recommended list because it has been
out of print. There have been several vegetation science textbooks
published since 1974, but their foci have been on ordination and
multivariate data analysis instead of on sampling methods. No other
text has covered the subject of vegetation sampling design in such
depth, breadth, and impartiality as this book, Aims and Methods of
Vegetation Ecology. Most of this material remains as current and
topical today as it was a quarter of a century ago, because the
progress that has been made in vegetation science is in the
computer-based treatment of sample data, not in the creation of new
sampling protocols.A new generation of vegetation ecologists can
now have the same advantage - the same easy access to this classic
reference work - that a past generation had in quantifying and
summarizing the formidable complexity of natural, wildland
vegetation." Foreword by Michael G. Barbour, Plant Ecologist,
University of California at Davis, Department of Environmental
Horticulture, November 2002.
English translation makes this unique book, now in its fourth
edition, available to a wider audience. This book is without doubt
the most important work ever published about the vegetation of
central Europe and its ecology. No other book contains so much
ecological information and discusses so many principles relevant
not only to plant ecologists in continental Europe, but to
ecologists and palaeoecologists in the British Isles and North
America. Besides providing valuable syntheses of the major plant
communities, Ellenberg details the ecology and environmental
requirements of all the vegetation types and discusses the climatic
tolerances and ecological physiology of many of the major species.
The account is based upon a life time of thorough field work and
experimental investigation. One of the major messages to be gleaned
from the book concerns the long-lasting and considerable effects of
human activity upon the vegetation, and the book therefore has much
to teach about the impact of agriculture and industrial pollution
and highlights the need to plan carefully for the conservation of
our rich natural and semi-natural environment.
