Abstract

The division rates of oceanic dinoflagellates in the genus Pyrocystis has been estimated by determining the fraction of their population which divided each day. For P. noctiluca, mean doubling times were 4 to 15 days at stations in the Tyrrhenian Sea in September, 1970, and 9 to 19 days at stations in the Sargasso Sea in April, 1971. For P. fusiformis, they were 7 to 18 days at stations in the Sargasso Sea in April, 1971. In many cases, the mean doubling times at different stations were statistically different, but the differences could not be explained using the available hydrographic data. © 1972.
