The heterotrophic dinoflagellate Protopemdinium cf. divergens, known as prey for adult copepods, itself feeds on copepod eggs and early naupliar stages. One to several P. cf. divergens can attack an egg or nauplius larger than themselves. The time for an egg to be digested was proportional to the number of P. cf. divergens attacking it. Ingestion rates of P, cf. djvergens on Acartia tonsa eggs ...

Changes in the composition of dinoflagellates from 1994 to 2001 at a station influenced by wind-induced seasonal upwelling off SW Portugal were analyzed relation oceanography. 194 taxa detected, most frequent belonged genera Tripos, Protoperidinium, Dinophysis, Diplopsalopsis, Prorocentrum and Lingulodinium. The dinoflagellate communities followed pattern, association with oceanographic forcing...

Two identical dinoflagellate cell specimens were found in a seawater sample collected from Tanjung Pasir Beach (TPB; 6.01 S, 106.8 N), Banten, Indonesia and subjected to morphological characterization light microscopy (LM). The cells measured 71.97–72.86 µm long 52.55–52.76 wide, fusiform or biconical-shaped, with tapered apical antapical horns. A sharp pointy spine was present at the antapex. ...

Amphidiniopsis is one of the most specious genera of sand-dwelling dinoflagellates. However, its systematic position and the affinities to other genera remain unresolved. We obtained the first SSU rDNA sequences of two species of Amphidiniopsis, A. hirsuta and A. swedmarkii collected from the French coasts of the English Channel. In the corresponding SSU rDNA phylogeny, the sand-dwelling Amphid...
