Toxin profiles of five geographical isolates of Dinophysis spp. from North and South America [PDF]

Toxicon, 2011
Marine dinoflagellates of the genus Dinophysis can produce toxins of the okadaic acid (OA) and pectenotoxin (PTX) groups. These lipophilic toxins accumulate in filter-feeding shellfish and cause an illness in consumers called diarrhetic shellfish poisoning (DSP).

A survey ofDinophysisspp. and their potential to cause diarrhetic shellfish poisoning in coastal waters of the United States [PDF]

Journal of Phycology, 2023
AbstractMultiple species of the genusDinophysisproduce diarrhetic shellfish toxins (okadaic acid andDinophysistoxins,OA/DTXsanalogs) and/or pectenotoxins (PTXs). Only since 2008 haveDSPevents (illnesses and/or shellfish harvesting closures) become recognized as a threat to human health in theUnited States.

Kleptoplasty in Dinophysis spp : Ecological role and evolutionary implications

, 2010
This thesis deals with the question of whether planktonic protits of the genus Dinophysis have permanent plastids (=chloroplasts) or practice kleptoplasty, i.e. acquire plastids via predation on other microorganisms. Sequencing the plastid 16S rDNA of Dinophysis spp.

Dinophysis spp. cells concentrated from nature for experimental purposes, using size fractionation and reverse migration [PDF]

Aquatic Microbial Ecology, 1995
A method based on size fractionation plus reverse phototactic migration was used to collect large Dinophysis spp.-dominated populations. Cells were active and survived handling and transportation. Experiments involving various treatments for establishing permanent cultures are described; none have yet been successful.

Detecting toxic dinoflagellates (Dinophysis spp.) using electrochemical genosensors [PDF]

, 2023
Aquatic environments are important economic and ecological sources for human activities (e.g. fisheries, tourism, agriculture and aquaculture). However, the increase in those practices has, over the years, compromised the integrity of these ecosystems.

Influence of prey concentration, light intensity, and temperature on the growth and ingestion of the mixotrophic dinoflagellate Pyrophacus horologium, a predator of the harmful species Heterocapsa niei. [PDF]

J Phycol
Abstract Pyrophacus horologium belongs to the family Pyrocystaceae and was recently identified as a mixotrophic dinoflagellate capable of feeding on other dinoflagellates. In this study, the growth and feeding responses of P. horologium were investigated under various environmental conditions by providing Heterocapsa niei, its preferred prey.

Unveiling the phylogenetic position of the type species of the syndinean genus Amoebophrya and broad divergence of the A. ceratii complex. [PDF]

J Phycol
Abstract The syndinean genus Amoebophrya comprises endoparasitic dinoflagellates that infect various marine protists. Since the description of the type species, A. sticholonchae, a parasite of the radiolarian Sticholonche zanclea, an additional six Amoebophrya species have been formally described.
