Iron uptake by the coastal diatom, Thalassiosira weissflogii, was measured by a technique
that exploits the Fe (III) reducing property of ascorbate to dissolve filterable colloidal iron. For …

Iron is taken up via specific sites on the cell surface in two coastal phytoplankters—the
coccolithophorid Pleurochrysis carterae and the diatom Thalassiosira weissflogii. Direct …

The copper sensitivity of the dinoflagellate Gonyaulax tamarensis was examined in artificial
