Abstract
The reproductive rates of 21 species of marine phytoplankton were measured in media in which free Zn, Mn and Fe ion activities were controlled at different levels. In general, the reproductive rates of neritic species were limited by Zn activities below 10-11.5M, while those of oceanic species were either not limited or only slightly limited at the lowest Zn activity attained in the experiment (10-13M). The reproductive rates of oceanic coccolithophores were either not limited or only slightly limited by the lowest Mn ion activity attained (10-11M) but those of a neritic coccolithophore and all diatoms, both neritic and oceanic, were limited below a Mn activity of 10-10M. Neritic species had reduced reproductive rates in media containing <10-7M Fe while oceanic species reproduced at maximal or close to maximal rates in the media with the lowest Fe concentrations (10-9M) . -from Authors
