Green Noctiluca scintillans: a dinoflagellate with its own greenhouse
The effect of irradiance on photosynthesis of the green form of the dinoflagellate Noctiluca scintillans was studied. Photosynthesis, measured in cells collected from the field and without the addition of prey, increased with irradiance to ca. 200 ng C cell–1 d–1 at an irradiance of ~250 to 300 μmol photons m–2 s–1. N. scintillans cells were observed to prey and grow actively on a number of dif...
متن کاملThe Nucleus of Noctiluca Scintillans
The unicellular organism, Noctiluca, has been examined with the electron microscope. The nucleus is small compared to the very large size of the cell, but the nuclear border has an organization which indicates an active nucleocytoplasmic exchange. Whereas annuli are missing over most parts of the nuclear membrane proper, there are "annulated vesicles" in a layer inside the nuclear membrane. The...
متن کاملTemporal abundance patterns of the red tide dinoflagellate Noctiluca scintillans along the southeast coast of Australia
Noctiluca scintillans was seasonally abundant during the austral spring and summer with typical values of 16 cells l–1, but depleted in autumn and winter, with values of <1 cell l–1. Peaks in abundance of up to 79 cells l–1 were observed, at the same time or subsequent to diatom blooms which were caused by episodic uplifting events during the spring and summer. The diatom blooms were dominated ...
متن کاملGrazing of heterotrophic dinoflagellate Noctiluca scintillans (Mcartney) Kofoid on Gymnodinium catenatum Graham.
A dinoflagellate bloom ("red tide" event) dominated by the toxic Gymnodinium catenatum Graham (Gymnodiniales, Dinophyceae; 99.7%) and the noxious Noctiluca scintillans (Mcartney) Kofoid (Noctilucaceae, Dinophyceae; 0.3%) was observed in Bahia de Mazatlán Bay, México, on 24-26 January 2000. Photographic and microscopic analysis of samples during such an event, allowed us to collect evidence of a...
متن کاملThe Flash-Triggering Action Potential of the Luminescent Dinoflagellate Noctiluca
The action potential which elicits luminescence in Noctiluca is recorded from the flotation vacuole as a transient all-or-none hyperpolarization in response to either local or general application of inward (bath to vacuole) current. Experiments were performed to determine whether the unorthodox polarities of both the stimulus current and the potential response resulted from uncommon bioelectric...
