monilata: population growth and development of toxicity in cultures.
Sweeney tested the ability of different wavelengths of light--corresponding to different colors--to shift the circadian rhythm in the photosynthetic marine dinoflagellate Gonyaulax
Balech (1974) used differences in the number and shape of cingular plates to separate Protoperidinium from Peridinium, and other taxa first described as species of Peridinium have been moved to other genera including Gymnodinium, Gonyaulax
, Ceratium, irhompsodinium and Glochidinium based on differences from the plate pattern of P.

Detection and quantification of melatonin in a dinoflagellate, gonyaulax
polyedra: solutions to the problem of methoxyindole destruction in non-vertebrate material.
These species, in such genera as Gonyaulax
and Gymnodinium, produce toxins in some species of bivalves living in the red tide seawater that are fatally toxic to man (Dale and Yentsch, 1978); other species of dinoflagellates do not.
In the ocean, the brownish, single-celled alga Gonyaulax
polyedra puts on an unusual light show.
Toxic red tide in the Argentine Sea: phytoplankton distribution and survival of the toxic dinoflagellate Gonyaulax
excavate in frontal area.
In the past, the dominant organisms responsible for red tides in the SCB have been the dinoflagellates Prorocentrum micans and Gonyaulax
polyedra, and mortality of fish and invertebrates have been associated with red water of the latter (Brongersma-Sanders 1957).
It wasn't until 1937 that California researchers proved that PSP in local mussels originated in the toxic dinoflagellate Gonyaulax
For the dinoflagellate Gonyaulax
tamarensis, it's a long timebetween wake-up calls.
A particularly extensive and intense bloom of the dinoflagellate Gonyaulax
spinifera occurred on the west coast of Vancouver Island in September 1990.
