Population dynamics of red tide dinoflagellates
Sea-surface discolorations due to high concentrations of phytoplankton are called red tides. Their ecological significance is a long standing puzzle, and they are sometimes considered pathological. Here we propose that many red tides, particularly but not exclusively those comprised of certain autotrophic dinoflagellates, are presexual/sexual swarms, essential links in their complex life cycles...
متن کاملInorganic carbon acquisition in red tide dinoflagellates.
Carbon acquisition was investigated in three marine bloom-forming dinollagellates-Prorocentrum minimum, Heterocapsa triquetra and Ceratium lineatum. In vivo activities of extracellular and intracellular carbonic anhydrase (CA), photosynthetic O2 evolution, CO2 and HCO3- uptake rates were measured by membrane inlet mass spectrometry (MIMS) in cells acclimated to low pH (8.0) and high pH (8.5 or ...
متن کاملEffect of red tide dinoflagellate diet and cannibalism on the bioluminescence of the heterotrophic dinoflagellates
The effects of diet and cannibalism were assessed from changes in the bioluminescence potential of 2 speclvb of the heterotrophic dinoflagellate Protoperidinium fed 4 specles of red tide dinoflagellate prey and also maintained without added prey. The use of bioluminescence as a sensitive indicator of nutritional status and feeding was explored. The bioluminescence of Protoperidinium cf. diverge...
متن کاملInteractions between the red tide dinoflagellates Heterocapsa circularisquama and Gymnodinium mikimotoi in laboratory culture
Interactions between Heterocapsa circularisquama and Gymnodinium mikimotoi, causative red tide dinoflagellates, were investigated using bialgal cultures. G. mikimotoi was killed by H. 21 circularisquama when the initial cell density of each species was set at 200 cells ml . However, cells of H. circularisquama transformed to temporary cysts when the initial cell density of G. 21 mikimotoi was i...
