Lake Constance, located along the Swiss-German Border is a large and
deep lake of of 183 sq-mi. area (11.3 cubic mi of water!) with well
established boundary conditions. Because Lake Constance has been the
subject of scientific study for more than a century, it is one of the
best studied lakes worldwide.
This volume documents, integrates and interprets a large body of new
hydrodynamic, chemical, paleolimnological and microbiological data
with data on plankton and fish ecology. The data were mostly collected
between 1979 and 1997 as part of an interdisciplinary research program
funded by the German Research Council (DFG).
The data provide novel insights into the complex dynamics of the
interaction of physical, chemical and biological processes in large
lakes. Mechanisms regulating the seasonal dynamics of phyto- and
zooplankton were identified, for example mechanisms controlled by
meteorological parameters.
By means of a unique set of plankton measurements with very high
temporal resolution, conducted over a period of almost two decades, the
effects of changes in nutrient supply and climatic parameters on major
plankton groups were quantified and modelled.
Quantitative models for large water bodies such as Lake Constance are
increasingly important to protect lake ecosystems, and thus important
water resources from anthropogenic mayhem.
From the perspective of the
plankton food web, Lake Constance is an ideal reference system for large
water bodies. The data and their interpretations are therefore not
only applicable to large lakes, but also to marine ecosystems, for
which comparable data cannot be gathered due to technical constraints.
The twenty-six contributions to this volume highlight the advantage of
interdisciplinary approaches to problems which in the past were commonly
considered to be essentially biological in nature.

Der Bodensee mit einer Fläche von 472 km2 (Wassermenge: 47 km3) wird
seit mehr als einem Jahrhundert wissenschaftlich untersucht und ist
mittlerweile einer der intensivst erforschten Seen der Welt.
Der vorliegende Band dokumentiert und integriert im Rahmen des
Sonderforschungsbereiches Stoffhaushalt des Bodensees
(1986-1997) durch multidisziplinäre Untersuchungen gewonnene
hydrodynamische, chemische, paläolimnologische, mikrobiologische,
planktologische und fischökologische Daten und Analysen.
Mit diesen Daten konnten neue Einsichten in ursächliche Zusammenhänge
des natürlichen Wechselspiels von physikalischen, chemischen und
biologischen Prozesse im Bodensee gewonnen werden.
So wurden die Mechanismen der Regulation der saisonalen Dynamik
des Phyto- und Zooplanktons aufgrund von wetterbedingten Veränderungen
in der Wassersäule (Turbulenz, Temperatur) erkannt.
Der Band stellt einen weltweit einmaligen Datensatzes von zeitlich
sehr hochauflösenden planktologischen Langzeit-Messungen (1979-1997)
vor. Mit diesen Daten war es möglich, das Zusammenspiel verschiedener
Einflüsse (rückläufige Nährstoffkonzentrationen und
z.B. Klimaeinwirkungen auf Temperaturschichtung und
Dynamik der Wassersäule) auf sämtliche pelagischen
Lebensgemeinschaften zu quantifizieren.
Die hier vorgestellten Ergebnisse sind für die Bewahrung unserer
Wasservorräte in einer immer stärker anthropogen geprägten Welt von
großer Bedeutung. Aus biologischer Sicht ist der Bodensee ein ideales
Modellsystem für große Freiwasserkörper. Die Ergebnisse dieser Studie
sind daher auch auf sehr große Seen und sogar marine Ökosysteme
übertragbar, an denen vergleichbare Freilandmeßprogramme nicht
realisierbar sind.
Mit den 26 Arbeiten des vorliegenden Band wird eine multidisziplinäre
Synopsis der Limnologie des Bodensees vorgelegt, die den ''state of
the art'' auf dem Gebiet der Seenforschung nicht nur für den Bodensee,
sondern auch für vergleichbare Wasserkörper definiert. Die Arbeiten
zeigen die Bedeutung interdisziplinärer Untersuchungen für Fragen, die
man früher als ''rein biologisch'' angesehen hätte.
