SEASONAL COMPOSITION OF TEMPERATE PLANKTON COMMUNITIES: FATTY ACIDS1
Fatty acid composition of the plankton in Narragansett Bay, Rhode Island, varies in relation to the seasonal succession and productivity of populations. The ratio of palmitoleic acid to palmitic acid declines during vernal warming from 2.0 to ca. 0.3, reflecting the change in dominance from diatoms...
