The fine structure of the cell surface in Gonyaulax polyedra (dinoflagellata)
Cell and Tissue Research, 1974The theca of Gonyaulax polyedra has been studied by light- and scanning electron microscopy. 1. The plates of “old” cells have growth rims in a regular pattern. 2. The growth rims overlap the margins of the adjacent plates. From this observation a rule of plate overlap can be deduced for the whole theca. 3.

Ultrastructural characterization of asexual cysts ofGonyaulax polyedra Stein (Dinoflagellata)
Protoplasma, 1995In the bioluminescent dinoflagellateGonyaulax polyedra, the formation of asexual cysts was elicited either by addition of 5-methoxytryptamine or by transfer to short-day conditions under lower temperature and decreased light intensity. The resulting changes were followed in vivo by light microscopy, and analysed ultrastructurally by electron microscopy.

A revision of Pyrodinium bahamense plate (dinoflagellata)
Review of Palaeobotany and Palynology, 1985Abstract A detailed study of Pyrodinium bahamense Plate, based on samples from Puerto Rico and Jamaica (Antilles), is presented and compared with the toxic material from New Guinea and the Philippines. In the material from the Antilles a very wide variation in shape, development of spines (including the apical one) and membranes has been documented ...

Life Cycle of the pseudocolonial dinoflagellatePolykrikos kofoidii(Gymnodiniales, Dinoflagellata)
Journal of Phycology, 2013The athecate, pseudocolonial polykrikoid dinoflag‐ellates show a greater morphological complexity than many other dinoflagellate cells and contain not only elaborate extrusomes but sulci, cinguli, flagellar pairs, and nuclei in multiple copies. Among polykrikoids,Polykrikos kofoidiiis a common species that plays an important role as a grazer of toxic ...

Unarmoured Dinoflagellata from Two Small Mazurian Lakes
Phycologia, 1965Abstract Katodinium mazuricum and Gymnodinium luteofaba are described as new. Gymnodinium limitatum Skuja and G. bogoriense Klebs are reported for the first time since their original description.

The Occurrence of Mixed Infections ofSymbiodinium(Dinoflagellata) within Individual Hosts
Journal of Phycology, 2012Coral reef ecosystems depend on symbiosis between dinoflagellates of the genusSymbiodiniumFreudenthal and their various hosts. The physiological characteristics associated with a particular lineage or species ofSymbiodiniumcan determine a host's susceptibility to harmful bleaching.

Three New Species of the Genus Alexandrium (Dinoflagellata)
Transactions of the American Microscopical Society, 1994Three new species of the dinoflagellate genus Alexandrium are described. Alexandrium tamiyavanichi is in the subgenus Alexandrium in which the Po and 1' are connected. This species is closely related to A. cohorticula, but it differs by its general shape, the Po and 1', the shape of its left sulcal list, and some sulcal plates.
