Die zunehmende Ozeanversauerung kann negative Effekte auf kalzifizierende Meeresorganismen haben. Wie eine neue Studie des GEOMAR Helmholtz-Zentrums für Ozeanforschung Kiel, der Christian-Albrechts Universität zu Kiel (CAU) und der Universität Göteborg zeigt, wachsen und bauen die Larven von Seeigeln ihr Kalkskelett langsamer, wenn sie ihre Entwicklung in versauertem Meerwasser durchlaufen müssen. Die Wissenschaftler zeigen in der Fachzeitschrift Proceedings of the National Academy of Sciences online erschienenen Arbeitpotentielle Wirkmechanismen auf. Die Studie wurde im Rahmen des BMBF-Verbundprojektes BIOACID (Biological Impacts of Ocean Acidification) und des Exzellenzclusters "Ozean der Zukunft" erstellt.
