Food selectivity and grazing impact on toxic Dinophysis spp. by copepods feeding on natural plankton assemblages

Harmful Algae, 2006
Food selectivity and grazing impact by Acartia bifilosa, Temora longicornis and Centropages typicus on Dinophysis spp. plankton assemblages were experimentally investigated in the Baltic Sea. Toxin analyses were carried out on phyto- and zooplankton-dominated size fractions from field-collected samples to assess if toxins produced by Dinophysis spp ...

Biología, autoecología y toxinología de Dinophysis spp.: Resultados del proyecto DINOPHYSIS 2000.

, 2004
Los estudios de biología, autoecología y toxinología de especies del género Dinophysisse han visto muy limitados por la normalescasez de estas especies, la falta de cultivos estables de las mismas, y las limitaciones de las técnicas analíticas al uso, que requieren muestras de varios cientos de células. En el transcurso del proyecto DINOPHYSIS 2000

Does prey availability influence the detection of Dinophysis spp. by the imaging FlowCytobot?

Harmful Algae, 2023
The Imaging FlowCytobot (IFCB) is a field-deployable imaging-in-flow cytometer that is increasingly being used to monitor harmful algae. The IFCB acquires images of suspended particles based on their chlorophyll-a fluorescence and/or the amount of light they scatter (side scattering).

A Novel Pectenotoxin, PTX-12, in Dinophysis Spp. and Shellfish from Norway

Chemical Research in Toxicology, 2004
Two novel pectenotoxins (PTXs) were detected by LC-MS in solid phase extracts of net hauls taken at Flødevigen, Norway, in June 2002 that were dominated by Dinophysis acuminata and Dinophysis norvegica. The new compounds were isolated as minor components from a large collection of a Dinophysis acuta-dominated bloom obtained from Skjer, Sognefjorden ...

The occurrence of the Dinophysis spp. on the eastern Adriatic coast

2005
Ecology and ecophysiology of the dinoflagellate genus Dinophysis are poorly understand mostly because of failure of culture as well as their scarcity. Dinophysis acuta, D. acuminata, D. caudata, D. fortii, D. rotundata, D. sacculus and D. tripos are recorded in the coastal Adriatic water.

Role of turbulence in Dinophysis spp. growth, feeding, and toxin leakage in culture

Harmful Algae
Dinophysis, a mixotrophic dinoflagellate that is known to prey on the ciliate Mesodinium rubrum, and retain its chloroplasts, is responsible for diarrhetic shellfish poisoning (DSP) in humans and has been identified on all U.S. coasts. Monocultures of Dinophysis have been used to investigate the growth of Dinophysis species in response to variations in

Diarrheic toxins in field-sampled and cultivated Dinophysis spp. cells from southern Brazil

Journal of Applied Phycology, 2013
In southern Brazil, mixotrophic dinoflagellates belonging to the Dinophysis acuminata complex have recently been involved in diarrheic shellfish poisoning episodes through the production of lipophilic toxins such as okadaic acid (OA) and dinophysistoxin-1 (DTX-1).

MOLECULAR STUDY OF THE TOXIC ALGAE DINOPHYSIS SPP. FROM THE FRENCH COAST

Journal of Phycology, 2000
Dinoflagellates of the genus Dinophysis are agents of Diarrhetic Shellfish Poisoning (DSP). They occur along the French coast and affect shellfish exploitation during most of the year (during spring, summer and autumn). Because this species is difficult to cultivate, very little is known about this organism. The first problem is the species‐delineation

Toxicity of Dinophysis spp. in relation to population density and environmental conditions on the Swedish west coast

Harmful Algae, 2007
The aim of this study in the field was to investigate whether there are differences between the outer archipelago (Gullmar Fjord) and a semi-enclosed fjord system (Koljo Fjord) in occurrences of D. acuta and D. acuminata as well as in their content of diarrheic shellfish toxin (DST) per cell. When all data pairs of cell toxicity of D. acuminata and the
