and their toxins on every US coast in recent years, the need to identify and monitor for problematic Dinophysis populations has become apparent. Here, we present morphological analyses, using light and scanning electron microscopy, and rDNA sequence analysis, using a ~2‐kb sequence of ribosomal ITS1, 5.8S, ITS2, and LSU DNA, of Dinophysis Dinophysiaceae. Genus: Dinophysis. Species: D. norvegica. Binomial name. Dinophysis norvegica. Claparède & J.Lachm.

Autotrophy through kleptoplastidy would be a secondary feature used as a complementary or short-term survival strategy. The pigment composition of Dinophysis norvegica Ehrenberg from the central Baltic Sea differs from the normal pigment pattern found in dinoflagellates, which contain peridinin as a typical marker such as Dinophysis acuminata, which occurs within a wide range of temperature regimes (Kamiyama et al., 2010), whereas others, such as Dinophysis norvegica and Dinophysis tripos, apparently with more restricted environmental tolerances, mainly occur in boreal and tropical-temperate waters, respectively (Reguera et al., 2012). 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 … Scientific Name. Dinophysis spp..

Natural samples were collected from Trondheim fjord, Norway, to analyse nutrient (O, C, N, P) and toxin (dinophysitoxins [DXTs], okadaic acid [OA], pectenotoxins [PTXs]) content in D. norvegica … Dinophysis norvegica, in shellﬁsh in the Gulf of Maine USA. Also provided are data on accumulation of this compound in commercial shellﬁsh species as well as preliminary methods of analysis. 1998-04-01 Dinophysis norvegica constituted 50-74% of cells in these fractionated samples.For each sampling occasion, photosynthesis-photosynthetic photon flux density (PPFD) relationships (P-I) were studied for the original bloom as well as for the fractionated phytoplankton using the 14 C … Dinophysis norvegica Claparède and Lachmann, 1859Taxonomic Serial No.: 9932. Claparède and Lachmann, 1859. Although published as part of an earlier work ("Identifying Marine Diatoms and Dinoflagellates," 1996), the 1997 compilation was used here. The editor's forword notes that "All nomenclatural novelties were validated in the original 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.

73-75. alloxanthin in dinophysis norvegica (dinophysiales, dinophyceae) from the baltic sea Bettina Meyer‐Harms Institut für Ostseeforschung, Sektion Biologische Meereskunde, Seestr. 15, D‐18119 Rostock, Germany The pigment composition of Dinophysis norvegica Ehrenberg from the central Baltic Sea differs from the normal pigment pattern found in dinoflagellates, which contain peridinin as a typical marker pigment. In D. norvegica isolated by cell fractionation of field samples, the major carotenoid was alloxanthin, a typical cryptomonad pigment.
