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 was not as sensitive to darkness and predominantly formed subsurface peaks, even below the euphotic zone. These occurrences were promoted by shallow stratification, Potentially toxic species identified in the Chesapeake include Dinophysis acuminata, D. acuta, D. fortii, D. caudata and D. norvegica. Toxicity Okadaic acid and dinophysistoxins, produced by Dinophysis spp., can accumulate in filter-feeders, such as bivalve shellfish, and adversely affect human health and marine life.

Binomial name. Dinophysis norvegica. Claparède & J.Lachm. Dinophysis norvegica is a species of dinoflagellate most commonly associated with diarrheal shellfish poisoning . 2008-02-01 · Dinophysis norvegica is one of the most abundant dinoflagellates in the open Baltic Sea in the summer and subsurface blooms of this species is a recurrent phenomena in the area (Carpenter et al., 1995, Gisselson et al., 2002, Salomon et al., 2003), however, little is known of its mode of nutrition Dinophysis norvegica is an armoured, marine, planktonic dinoflagellate species. This species is a bloom -forming toxic species associated with DSP events.

2016 Maine D. norvegica Bloom •From July 5 –August 29, 2016 a large monospecific bloom of D. norvegica occurred on the central coast of Maine. •Maine Department of Marine Resources (ME DMR) found levels of DSTs in excess of the 16 µg/100g OA eq.US guidance level by PPIA and closed shellfish harvesting on July 20.

The number of D. norvegica cells within one FP ranged from 0 to 32, with an aver-age of 19 ± 2.5 SE. This represents an ingestion rate of 400 to … Due to the increasing prevalence of Dinophysis spp. 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.

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. 2002). However, there is no information regarding the seasonal pattern of infec-tion of D. norvegica by the parasite in the Baltic Sea. D. norvegica is one of the most abundant dinoflagellates 3 August 1990 when Dinophysis norvegica occurred in red-tide proportions in the Bedford Basin.

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.
