Arbeitsgruppe 脰kophysiologie

Die Arbeitsgruppe 脰kophysiologie (Fachbereich 3, Forschungseinheit 'Benthos枚kologie') besch盲ftigt sich mit den Effekten von abiotischen Faktoren (Sauerstoff, Kohlendioxid, Temperatur) auf physiologische Prozesse und deren 枚kologische Konsequenzen. Unsere Studien werden im Labor und im Freiland durchgef眉hrt. Modellorganismen sind prim盲r 枚kologisch und 枚konomisch wichtige Weichtiere (Mollusken), Stachelh盲uter (Echinodermaten), Korallen, sowie Zooplanktonorganismen. Mittels intensiver und teilweise die Generationsgrenze 眉berschreitender Laborarbeit versuchen wir abzusch盲tzen, inwiefern sich Schl眉sselorganismen an einen zuk眉nftigen, w盲rmeren und saureren Ozean anpassen k枚nnen. Zudem versuchen wir verschiedene physiologische Prozesse zu verstehen, die ein 脺berleben im Meer m枚glich machen, z.B. die Regulation des K枚rperionenhaushaltes und die F盲higkeit, Schalen aus Kalziumkarbonat zu bilden.
