| Phytoplankton constitute the medium whereby carbon is transformed from the inorganic to the organic state in pelagic ecosystems. In terrestrial plants, the super(13)C/ super(12)C ratio of the organic matter (expressed as delta super(13)C) is a good indicator of carbon pathway. We measured this ratio together with three carboxylase activities: ribulose-1,5-bisphosphate carboxylase, phosphoenolpyruvate and phosphoenolpyruvate carboxykinase on Mediterranean phytoplankton communities. Results were obtained in the field during the Phycarb cruise in February 1984 and during the Epice experiment in a simulated enclosed water layer at Villefranche-sur-Mer in November 1984. These data were compared with those obtained previously on temperature phytoplankton (diatom... |
