(PresseBox) (Kiel, )
Jüngere Exemplare einer Seesternart aus der Ostsee verkraften die Versauerung des Meerwassers offenbar weniger gut als ihre erwachsenen Artgenossen. Wissenschaftler des GEOMAR Helmholtz-Zentrums für Ozeanforschung Kiel zeigten in einem Labor-Experiment, dass jüngere Tiere bereits unter geringfügig erhöhtem Kohlendioxid-Gehalt weniger fressen und langsamer wachsen als unter Normalbedingungen. Ihre Ergebnisse veröffentlichen die Forscher in der Fachzeitschrift Marine Ecology Progress Series.
