Article
Full-text available
Dinoflagellate species of Dinophysis are obligate mixotrophs that require light, nutrients, and prey for sustained growth. Information about their nitrogenous nutrient preferences and their uptake kinetics are scarce. This study aimed to determine the preferred nitrogen sources in cultures of D. acuminata and D. acuta strains from the Galician Rías...
Article
Dinoflagellate species of Dinophysis, in particular D. acuminata and D. acuta, produce lipophilic toxins that pose a threat to human health when concentrated in shellfish and jeopardize shellfish exploitations in western Europe. In northwestern Iberia, D. acuminata has a long growing season, from spring to early autumn, and populations develop as s...
Article
Full-text available
Kleptoplastic mixotrophic species of the genus Dinophysis are cultured by feeding with the ciliate Mesodinium rubrum, itself a kleptoplastic mixotroph, that in turn feeds on cryptophytes of the Teleaulax/Plagioselmis/Geminigera (TPG) clade. Optimal culture media for phototrophic growth of D. acuminata and D. acuta from the Galician Rías (northwest...
Article
Full-text available
Dinoflagellates of the genus Dinophysis are the most persistent producers of lipophilic shellfish toxins in western Europe. Their mixotrophic nutrition requires a food‐chain of cryptophytes and plastid‐bearing ciliates for sustained growth and photosynthesis. In this study, cultures of D. acuminata and D. acuta, their ciliate prey Mesodinium rubrum...

Article
Full-text available
Photosynthetic species of the genus Dinophysis are obligate mixotrophs with temporary plastids (kleptoplastids) that are acquired from the ciliate Mesodinium rubrum, which feeds on cryptophytes of the Teleaulax-Plagioselmis-Geminigera clade. A metabolomic study of the three-species food chain Dinophysis-Mesodinium-Teleaulax was carried out using ma...
Article
Full-text available
The presence of the benthic dinophysoid dinoflagellate Sinophysis canaliculata has been reported in the Canary Islands (eastern central Atlantic) in live field observations and on fixed macroalgae samples from intertidal ponds (26 sampling sites from El Hierro, Tenerife, Gran Canaria, Fuerteventura and Lanzarote islands). In vivo Sinophysis cells w...

Full-text available
In the course of a recent sampling of benthic dinoflagellate communities in the Canary Islands (late summer 2015) we observed the widespread occurrence of Sinophysis on microalgae samples (Fig. 1).As far as we know, this benthic dinoflagellate genus has not been reported previously in these islands. The morphological traits of Sinophysis cells corr...

Full-text available
Dinophysis acuminata and D. acuta are the main producers of DSP toxins in western Europe. In western Iberia, these mixotrophic species exhibit important differences in their phenology, micro spatial-temporal distribution and impact in shellfisheries. -To understand these differences and the contribution of photosynthesis versus heterotrophy, a 21-d...
