Arbeitsgruppe Biodiversität

Überblick

Die Arbeitsgruppe beschäftigt sich mit den Mechanismen, die die Biodiversität eines Ökosystems regulieren, sowie mit der Bedeutung von Biodiversität für Ökosystemleistungen. Ein Schwerpunkt liegt in der Erforschung möglicher Auswirkungen des Klimawandels auf die Interaktion (Konkurrenz und Konsum) zusammenlebender Arten und den daraus (möglicherweise) resultierenden Konsequenzen für bestehende Ökosystemleistungen. Als experimentelle Modellsysteme nutzen wir Phytoplankton und benthische Makro- und Mikroalgen mit ihren assoziierten Konsumenten. In nahezu natürlichen Gemeinschaften und/ oder über längere Zeiträume wird untersucht welche direkten und indirekten Mechanismen des Klimawandels Einfluss auf die ökologischen Gemeinschaften nehmen. Ziel ist es, durch genauere Kenntnis der Wirkungsmechanismen die Folgen des Klimawandels für Meeresökosysteme realistisch einschätzen zu können. Letzteres beinhaltet auch die Einschätzung der Widerstandskraft von Ökosystemen.
