Dinoflagellates are a major component of the modern plankton. Of the 2192 species of marine free-living dinoflagellates presently described, an increasing number are being shown to produce resting cysts (probably hypnozygotes) within their life cycle. With rare exception, only the resting cysts fossilize, so they are of central importance in tracing the history of dinoflagellates through geological time. Cysts of many of the more common dinoflagellate species have distinctive morphologies allowing their geographic and stratigraphic occurrences to be traced. An ever-increasing number of taxa are also being shown to produce distinctive cysts, potentially increasing our knowledge of the diverse representation of dinoflagellates through time. Here the...

Light and dark carbon uptake by Dinophysis species in comparison to other photosynthetic and heterotrophic dinoflagellates
Provedor de dados: 5
Autores: Graneli, Edna; Anderson, Donald M; Carlsson, Per; Maestrini, Serge Y.
The marine dinoflagellate genus Dinophysis includes species that are the causative agents of diarrhetic shellfish poisoning (DSP). Recent findings indicate that some Dinophysis species are mixotrophic, i.e. capable of both autotrophic and heterotrophic nutrition. We investigated inorganic (and organic) carbon uptake by several species of Dinophysis in the Light and dark using the 'single-cell C-14 method', and compared uptake rates with those of photosynthetic Ceratium species and heterotrophic dinoflagellates in the genus Protoperidinium. Experiments were conducted with water from the Gullmar Fjord and from the Koster Strait (Swedish west coast). Nutrient-enriched phytoplankton from surface water samples were concentrated (20 to 70 mu m) and incubated at...

Dinoflagelados (Peridiniales, Prorocentrales) do microplâncton na plataforma continental e talude do extremo sul do Brasil (inverno 2005, verão 2007)
Provedor de dados: 49
Autores: Islabão,Carolina Antuarte; Odebrecht,Clarisse.
Este estudo teve por objetivo identificar as morfo-espécies de dinoflagelados do microplâncton (&gt;20 μm) das Ordens Peridiniales e Prorocentrales ao largo do Cabo de Santa Marta Grande, CSMG (SC, 28º 40' S) e Albardão-Chuí, AC (RS, 34º 40' S) durante dois cruzeiros oceanográficos: inverno de 2005 e verão de 2007. Amostras de plâncton foram coletadas através de arrastos verticais com rede de plâncton (20 μm), preservadas com formalina 4% e analisadas ao microscópio invertido equipado com câmara digital. Quando necessário, a identificação de espécies de Peridiniales foi efetuada através do número e morfologia das placas da teca realçadas com Calco Flúor Branco MR2; espécies de Prorocentrales foram identificadas com base em seu tamanho, forma, presença de...
