E2.1 | VEGETATIONSDYNAMIK UND ÖKOSYSTEMPROZESSE

Weil Vegetationsdynamik und Ökosystemprozesse miteinander wechselwirken, stellen wir beide in integrierten Modellen dar. Dabei werden verschiedene Prozesse integriert, von der lokalen Populationsdynamik von Pflanzen, über Sukzessionsmuster in Wäldern, Störungen wie bspw. Waldbränden, bis zur globalen Verteilung von Vegetationstypen (sogenannten Biomen) und globalen biogeochemischen Kreisläufen (z. B. Kohlenstoff, Wasser und Stickstoff). Ein wichtiger Modelltyp sind sogenannte Dynamische Globale Vegetationsmodelle (DGVM). Wir koppeln diese Modelle auch mit Klimamodellen, um die Bedeutung der terrestrischen Biosphäre für das Klima zu erforschen (siehe Projektgruppe E1). Weil Ökosysteme die Habitate von allen Arten darstellen, sind die Ergebnisse auch für die Arealmodellierung von Bedeutung (Projektgruppe E2.2). Daten aus verschiedenen Projektbereichen werden genutzt, um die Modelle zu parametrisieren oder zu testen, bzw. um durch die Kombination von Daten und Modellexperimenten Hypothesen zu testen. Die Ergebnisse stehen oft in enger Beziehung zu für unsere Gesellschaft wichtigen Ökosystemfunktionen, beispielsweise der Produktion von Biomasse und der Speicherung von Kohlenstoff.
