Wie reagieren Pflanzenökosysteme langfristig auf die steigende Konzentration des Treibhausgases CO2 in der Atmosphäre? Diese grundlegende Frage stellt sich vor dem Hintergrund des Klimawandels immer drängender. Forscher vom Lehrstuhl für Gründlandlehre der Technischen Universität München (TUM) haben sie nun - weltweit zum ersten Mal - für Grasland untersucht. Antworten fanden die Wissenschaftler an ungewohnter Stelle: in Steinbockhörnern aus der Schweiz und in 150 Jahre altem Heu aus England.
Forscher, die die Reaktion von Bäumen auf die steigende CO2-Konzentration in der Luft untersuchen möchten, haben es leicht: Sie müssen nur einen Bohrkern aus dem Stamm nehmen, denn Bäume speichern den aufgenommenen Pgujoalkkzc it Cgve.
