摘要：

Total productivity rates and the component attributed to the diatom proportion in the crop were measured in natural water samples taken from the Scripts Pier (La Jolla, California) at ca, monthly intervals in 1975–76. Two other measurements were done in water samples taken from Saanich Intel, Vancouver Islands, British Columbia (Canada). The percent of photosynthesis by diatoms was compared with the proportion of diatom carbon in the crop. In all instances, percent diatom photosynthesis was higher than percent diatom carbon for dialoms were higher than those of other algae. It is hypothesized that, in the sea, diatoms can outcompete other algae. However, the assemblages consist of some tens of species coexisting, and no portion of the crop out competes the others to exclusion. Copyright © 1978, Wiley Blackwell. All rights reserved
