Significant CO2 fixation by small prymnesiophytes in the subtropical and tropical northeast Atlantic Ocean
Global estimates indicate the oceans are responsible for approximately half of the carbon dioxide fixed on Earth. Organisms <= 5 mu m in size dominate open ocean phytoplankton communities in terms of abundance and CO(2) fixation, with the cyanobacterial genera Prochlorococcus and Synechococcus nu...

Global estimates indicate the oceans are responsible for approximately half of the carbon dioxide fixed on Earth. Organisms <= 5 mu m in size dominate open ocean phytoplankton communities in terms of abundance and CO(2) fixation, with the cyanobacterial genera Prochlorococcus and Synechococcus numerically the most abundant and more extensively studied compared with small eukaryotes. However, the contribution of specific taxonomic groups to marine CO(2) fixation is still poorly known. In this study, we show that among the phytoplankton, small eukaryotes contribute significantly to CO(2) fixation (44%) because of their larger cell volume and thereby higher cell-specific CO(2) fixation rates. Within the eukaryotes, two groups, herein called Euk-A and Euk-B, were distinguished based on their flow cytometric signature. Euk-A, the most abundant group, contained cells 1.8 +/- 0.1 mu m in size while Euk-B was the least abundant but cells were larger (2.8 +/- 0.2 mu m).
