The temporal and vertical distribution of the infection of the dinoflagellate Dinophysis norvegica by the endoparasite Amoebophrya sp. was investigated at a fixed sampling location in the Baltic Sea during 2000 and 2001. Infected hosts were detected by epifluorescence microscopy after DAPI staining. Dinophysis acuminata and D. norvegica were found to be the two most abundant species of their genus, and made up most of the Dinophysis species detected during cell counts. Dinophysis acuminata and D. norvegica both showed a short-lived abundance increase in the late spring/early 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 Global Biodiversity Information Facility. Free and Open Access to Biodiversity Data. parasiten specialiserar sig enbart på Dinophysis norvegica eller angriper och dödar andra, nyttiga eller harmlösa alger också.

A total of 98% of the FP produced during the experiment contained D. norvegica. 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.

AU - Salomon, P. S. AU - Janson, S. AU - Graneli, Edna Dinophysis is a genus of dinoflagellates common in tropical, temperate, coastal and oceanic waters.

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 method (Steemann-Nielsen, 1952).

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. 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.
