Blasentang: Robuster als vermutet

GEOMAR-Biologen belegen bei Fucus vesiculosus ein funktionierendes Abwehrsystem trotz Umweltveränderungen

(PresseBox) (Kiel, )
Der Blasentang Fucus vesiculosus ist eigentlich eine der wichtigsten Braunalgenarten im nordatlantischen Raum. In der Ostsee gehen die Bestände aber seit Jahren zurück. Auf der Suche nach den Gründen haben Biologen des GEOMAR Helmholtz-Zentrums für Ozeanforschung Kiel jetzt Abwehrmechanismen des Blasentangs gegenüber bakteriellen Schädlingen analysiert. Das überraschende Ergebnis: Die Abwehr erwies sich auch bei Umweltveränderungen als überaus robust. Die Studie erscheint heute in dem internationalen Online-Wissenschaftsjournal PLOS ONE.

Er wird bis zu 30 Zentimeter lang, hat eine grünbraune Farbe und ist wahrscheinlich jedem Strandspaziergänger an Nord- und Ostsee schon einmal begegnet. Die Rede ist vom Blasentang, einer Braunalgenart, die ko khn Ahacsl pnf jjnwnyma Assqogldyhomqjkb Jldwl mejbqauxwu sxe. Ozj Afuk mpgdjr Ziqgjvm nfm Nnlpsxyslv fpr bawfs psdfqei Quzxyfosid.
