Notes for a Short Course: Studies in Geology, 1987
Dinoflagellates are single-celled organisms of the Division Pyrrhophyta. Most people, although not familiar with dinoflagellates, are familiar with their effects. Bioluminescent dinoflagellates cause a sparkling of the sea at night as the waves break, and certain dinoflagellates may produce blooms called “red tides,” which poison marine life or which ...

Most dinoflagellates are free-living single-celled organisms that inhabit aquatic environments with a mostly organic-walled cyst stage in their life cycle. The evolution of dinoflagellates through their cyst fossils goes back to Middle Triassic. The intricate Jurassic through Cenozoic organic walled cyst taxonomy allows a refined marine biostratigraphy.

Speciation and Symbiotic Dinoflagellates
Science, 1985Morphometric analyses based on three-dimensional reconstruction of the nuclei of four different strains of the symbiotic dinoflagellate Symbiodinium microadriaticum , the algae that inhabit corals, giant clams, and other marine invertebrates, revealed marked differences in chromosome numbers and chromosome volumes ...

Parasitic, amoeboid dinoflagellates
Nature, 1979SEXUAL reproduction has so far been unknown among the Dinococcales, unicellular brown algae belonging to the Dinophyceae (dinoflagellates). As we report here, however, the life cycles of two members of this group, Stylodinium sphaera and Cystodinedria inermis, include a parasitic amoeboid stage which brings about vegetative reproduction and also ...

Protist, 2001
Dinoflagellates possess two flagella; usually these are directed perpendicular to one another constituting a transversal flagellum and a longitudinal, trailing flagellum, respectively. The transversal flagellum causes the cell to rotate around its length axis.

Dinoflagellate Genome Evolution
Annual Review of Microbiology, 2011The dinoflagellates are an ecologically important group of microbial eukaryotes that have evolved many novel genomic characteristics. They possess some of the largest nuclear genomes among eukaryotes arranged on permanently condensed liquid-crystalline chromosomes.

Ultrastructure of the Dinoflagellate Amphiesma
1983Publisher Summary This chapter discusses the ultrastructure of dinoflagellate amphiesma. Amphiesma is a complete cell covering of a dinoflagellate. The chapter examines a number of amphiesmal structures and discusses the ontogeny of various components of amphiesma.

Dinoflagellates: A Selective Review
Proceedings of the Annual Meeting. American Association of Stratigraphic Palynologists, 1970Abstract A brief history of the investigation of fossil dinoflagellates and a summary of certain biological considerations are followed by a survey of recent progress along selected lines in the study of these organisms. Some of the new information that has come to light as a result of the reinforcing interplay between biological and paleontological ...
