The aim of this PhD-thesis was to contribute to the existing knowledge on the role
of diazotrophic cyanobacteria in marine environments. In the first part dealt with
N2 and C fixations as well as the release of N and C compounds, which were tightly
regulated. The second part aimed at the quantification of diazotrophic N transferred
to mesozooplankton species. Because filamentous cyanobacteria are grazed upon only
by a limited number of zooplankter the profound transfer of newly fixed N in the Baltic
Sea was mediated by microbial loop constituents (67%).

Das Ziel dieser Promotion war es, die Rolle N2 fixierender Cyanobakterien in marinen
Ökosystemen zu beleuchten. Im ersten Teil der Arbeit wurden N2 und C Fixierung untersucht,
sowie die anschließende Abgabe gelöster N und C Verbindungen, welche sich als eng
an die Quantität des vorher fixierten N2 gekoppelt herausstellte. Der zweite Teil
hatte das Ziel, den Transfer von diazotrophen N in das Mesosooplankton zu quantifizieren.
Da filamentöse Cyanobakterien nur selten direkt gefressen werden, erfolgte der vorwiegende
Anteil des Transfers über das mikrobielle Nahrungsnetz (67%).
