Die einzellige Kalkalge Emiliania huxleyi zeigte im einjährigen Laborversuch großes Potential, sich an Umweltveränderungen im Meer anzupassen. In einem aufwändigen Langzeitexperiment gelang es Forschern des GEOMAR | Helmholtz-Zentrum für Ozeanforschung Kiel, Kulturen der biogeochemisch wichtigen Kalkalge über 500 Generationen unter versauerten Bedingungen des zukünftigen Ozeans zu halten. Auf diese Weise angepasste Populationen zeigten deutlich bessere Wachstums- und Kalkbildungsraten als die Kontrollpopulationen. Damit konnte erstmals der Beweis erbracht werden, dass eine evolutionäre Anpassung an die sinkenden pH-Werte im Ozean möglich ist. Grund zur Entwarnung sehen die Forscher aber noch nicht. Die Studie erscheint in der aktuellen Ausgabe des Fachmagazins Nature Geoscience.
