Das Pflanzenwachstum auf einer Wiese ist abhängig von der Verfügbarkeit mehrerer Nährstoffe gleichzeitig. Und: Die zunehmende Beschattung durch das vermehrte Wachstum der Pflanzen nach einer Düngung erklärt nicht vollständig den damit einhergehenden Verlust an Artenvielfalt. Das sind die zwei wichtigsten Ergebnisse einer internationalen Studie, an der auch Leipziger und Hallenser Forscher beteiligt waren. Die Wissenschaftler relativieren damit zwei etablierte Lehrsätze der Pflanzenökologie, die jeweils nur einzelne Faktoren in den Vordergrund stellen und damit die Vielfalt in realen Systemen nicht hinreichend erklären. Um die Auswirkungen des globalen Wandels zu verstehen und vorhersagen zu können, plädieren sie im Fachjournal NATURE für eine ctpepxfstnftgqvfs Fqalwfcmbag syu qe tqdhsbxfz Puzof hqqyngloshu us Rqzmiqagz gmmfioikn Temjomjmbopluwaj.
