DynaTrait
Unser Ziel ist es, die ökologische Theorie voranzubringen und eine Grundlage für verbesserte Managementpraktiken zu schaffen, um die Folgen von Umweltveränderungen und dem Verlust der biologischen Vielfalt abzumildern, und andere Disziplinen wie Zellbiologie, Sozialwissenschaften oder Transport anzuregen, die sich ebenfalls der Netzwerkwissenschaft bedienen. DynaTrait bewegt sich weg vom klassischen statischen artenbasierten Ansatz (bei dem jedem Organismus oder jeder Art starre Eigenschaften unabhängig von den Umgebungsbedingungen zugewiesen werden) zu einem innovativen, flexiblen, merkmalsbasierten Ansatz. Es berücksichtigt ausdrücklich funktionale Merkmale, die messbare Eigenschaften sind (z. B. Essbarkeit von Beutetieren, Selektivität von Verbrauchern), die sich je nach den vorherrschenden Bedingungen im Laufe der Zeit ändern können. Wir streben ein intensives, sich gegenseitig stimulierendes Wechselspiel zwischen experimentellen Ansätzen, Feldmessungen und mathematischer Modellierung an, wobei vor allem Plankton und Biofilme als empirische Modellsysteme verwendet werden. Diese mikrobiellen Nahrungsnetze umfassen mehrere trophische Ebenen mit internen Rückkopplungen, und ihre geringe Größe und kurzen Generationszeiten ermöglichen die Messung und Manipulation von Merkmalsvariationen und die Schätzung der wichtigsten Kompromisse zwischen Merkmalen. Die Populationsdynamik kann für viele Generationen quantifiziert werden, was die Wirkung ökoevolutionärer Rückkopplungen innerhalb machbarer Zeitskalen aufzeigt. Wir wollen unser sehr begrenztes quantitatives Wissen und unsere Vorhersagekraft darüber erweitern, wie Biodiversität die Art der ökologischen Dynamik (z. B. statisch oder oszillierend) und Reaktionen auf Umweltveränderungen beeinflusst.
