TY - BOOK AU - Isensee, Kirsten PY - 2011 DA - 2011// TI - Responses of filamentous cyanobacteria to natural and anthropogenic changes in the Baltic Sea AB - The studies concentrated on 2 diazotrophic cyanobacteria species, Nodularia spumigena and Aphanizomenon sp.. The dissertation includes diurnal observations, laboratory and field studies. The experiments aimed to observe variations concerning day/night rhythms and anthropogenic induced changes of pCO2 levels. I showed 2 to 4 fold diurnal variations within DIC, N2, DIP incorporations, related to daytime and bloom development. Further I showed stimulated C and N2 fixation rates with increasing pCO2 at sufficient DIP concentrations. Reduced or depleted DIP concentrations debate this effect.
