For each cell, elemental maps were created and the cellular C, N, and P content was obtained. Three distinct morphospecies were documented in mid‐Atlantic surface waters: D. acuminata, D. norvegica, and a “small Dinophysis sp.” that was morphologically distinct based on multivariate analysis of morphometric data but was genetically consistent with D. acuminata. Dinophysis norvegica. Credit WHOI . The biological source of Dihydrodinopyhysistoxin-1 (aka dihydro-DTX1), a toxin that causes diarrhetic shellfish poisoning and once described from a marine sponge, is of yet unknown. norvegica, D. caudata) showed either small amounts of the same toxins (OA, DTXs, PTXs) present in the co-occurring Dinophysis species or no toxins at all Aug 31, 2020 A bloom of Dinophysis norvegjca, a dinoflagellate associated with diarrhetic shellfish poisoning, was reported by Subba Rao et al. (1993) in Potentially toxic species identified in the Chesapeake include Dinophysis acuminata, D. acuta, D. fortii, D. caudata and D. norvegica.

Dinophysis acuminata and D. norvegica have mainly been abundant from March to December, whereas D. acuta has typically occurred in late summer and autumn (August-December). For all three species we have observed a narrowing of the peak season since 2002 at the same time as they have become less abundant. 2019-jan-30 - Denna pin hittades av Kelly.

Observations of the dinoflagellate Dinophysis norvegica in the Baltic Sea during the summers of 1991–1993 indicate that maximal abundances (c 40–150 × 103 cells l-1) were found at the thermocline, dinoflagellate Dinophysis norvegica (Janson et al. 2000), with prevalence ranging from 0.2 to 6% during sum-mer months (Gisselson et al.

debilior) and even suggested separating them into D. norvegica and D. de-bilior. Dinophysis acuminata is best distinguished from D. norvegica and D. acuta by its small size and usually Our main conclusion is that D. norvegica, and probably all other species from the genus Dinophysis, is mainly phagotrophic and feeds on a larger prey than T. amphioxeia. Autotrophy through kleptoplastidy would be a secondary feature used as a complementary or short-term survival strategy. Global Biodiversity Information Facility.
