Growth and grazing rates of the heterotrophic dinoflagellates Protoperidinium spp
Cannibalism was observed in cultures mainly when Protoperidinium abundances were high, and may be a mechanism for withstanding prolonged starvation and may have a considerable grazing impact on some red tide dinoflagellate populations.
The reversible effect of flow on the morphology of ceratocorys horrida (PERIDINIALES, DINOPHYTA)*
Although their abundance did not change, single‐cell studies and morphological characteristics suggest that the spineless cells can rapidly transform to and from other cell types, even though the former are larger and have a higher cell density.
Effect of growth conditions on flow‐induced inhibition of population growth of a red‐tide dinoflagellate
The population growth of some dinoflagellates is known to be reduced by exposure to fluid flow. The red‐tide dinoflagellate Lingulodinium polyedrum was used to examine the effect of growth conditions…
MARINE BIOLUMINESCENCE SPECTRA MEASURED WITH AN OPTICAL MULTICHANNEL DETECTION SYSTEM.
Evidence is presented that the narrow bandwidth of the emission spectrum for Argyropelecus affinis (Pisces) is due to filters in the photophores, and a large collection of bioluminescence spectra of precision rarely obtained previously with such material is acquired.
Evidence for enhanced bioavailability of trace elements in the marine ecosystem of Deception Island, a volcano in Antarctica.

It is suggested that scleractinian corals regulate GFP to modulate the internal light environment and support the hypothesis that GFP has a photoprotective function.
Effect of fluid shear and irradiance on population growth and cellular toxin content of the dinoflagellate Alexandrium fundyense
Cultures of the dinoflagellate, Alexandrium fundyense, a producer of toxins responsible for paralytic shellfish poisoning, were exposed to quantified laminar shear generated in Couette flow for 1‐24 h d 21.
Spectral composition of bioluminescence of epipelagic organisms from the Sargasso Sea
The spectral characteristics of single identified epipelagic sources of bioluminescence from the western Sargasso Sea were measured with an optical multichannel analyzer (OMA) system during the April, 1985, Biowatt cruise, suggesting that the spectral emissions in the upper water column will vary, based on species assemblage.
Internal and secreted bioluminescence of the marine polychaete Odontosyllis phosphorea (Syllidae)
Results suggest that bioluminescence from the mucus may involve a photoprotein rather than a luciferin–luciferase reaction, and may be used for purposes other than attracting mates.
Chemical speciation and toxicity of metals assessed by three bioluminescence‐based assays using marine organisms
The Microtox® bioassay was sensitive to all metals (except Pb), whereas the photocytes were the least sensitive to the metals, probably resulted from a combination of the limited complexing power of the medium and the greater sensitivity of the bacterial strain.
