Wie reagieren Bäume auf den Klimawandel? Und wieso wird trockenheitsbedingtes Waldsterben nicht nur in wasserarmen, sondern auch in feuchten Gebieten beobachtet? Eine internationale Forschergruppe um Dr. Steven Jansen von der Universität Ulm und Dr. Brendan Choat (University of Western Australia, Sydney) hat in dreijähriger Arbeit mehr als 226 Arten an 81 Standorten weltweit untersucht. Ihre einmalige Datensammlung birgt erstaunliche Ergebnisse: "Bäume passen sich optimal an ihren Standort an indem sie das verfügbare Wasser effizient nutzen. Ändern sich die Umweltbedingungen, sind sie anfällig für trockenheitsbedingte Sterblichkeit. Dieser Verwundbarkeit lässt sich für alle Großlebensräume nachweisen - egal ob feucht oder trocken", erklärt Ymlejq, Pqsspuxmqqueyhk tf Euqfr Qkpumhoq uxq Meqfgytqsgnct Zmwcsne vhg pniubiwf.
