Die Tropenwälder rund um den Globus beherbergen eine große Artenvielfalt und sind ein wichtiger Kohlenstoffspeicher. Doch nach wie vor werden sie durch Abholzungen weiter zerschnitten und damit gefährdet. Wissenschaftler des UFZ haben aus der Physik eine Methode abgeleitet, mit der sich die Fragmentierung erstmals auf globaler Ebene erklären und mathematisch beschreiben lässt. Dabei zeigte sich beispielsweise, dass sich die Tropenwälder aller drei Kontinente nahe an einem kritischen Punkt befinden, ab dem die Anzahl der Fragmente stark ansteigen wird. Dies wird schwerwiegende Folgen für die Biodiversität und die Kohlenstoffspeicherung haben, schreiben die Forscher im Wissenschaftsjournal Nature.
