Prorocentrum dentatum, another dinoflagellate, was responsible for water discolorations in Berowra Creek in May 2003 albeit with no toxic effects. This species is highly variable in size and shape. Conversely, this primer pair was able to amplify DNA from a broad sampling of dinoflagellate taxa including Prorocentrum minimum, Gonyaulax cochlea, Peridinium foliaceum, Gymnodinium sanguineum, and Coolia monotis (Table 2 in the supplemental data). Biological weighting functions were estimated for UV inhibition of photosynthesis and showed that the high‐light‐grown cultures have lower .

Therefore, it lacks a thick cellulose wall, the theca, common in other genera of dinoflagellates.Reproduction of the phytoplankton species is primarily asexual.. The influence of hydrophobic (humic and fulvic acids) and hydrophilic acids (extracted from river runoff by XAD-8 resin) on eight nuisance marine phytoplankton was investigated. This raises two questions: how do the sponges live in the cold environment; or, more specifically, (a) how do they solve The three main dinoflagellates showing up are Cochlodinium catenatum, Gymnodinium sanguineum, and various species of Ceratium.
