Phytoplankton blooms were due to the diatom Thalassiosira pseudonana and the dinoflagellate Prorocentrum cordatum. Ecdysis, the process of extensive cell covering rearrangement, represents a remarkable physiological trait of dinoflagellates. More frequent and intense algal blooms, red tides (i.e. 2010). Noctiluca, Prorocentrum cordatum) and changes in species composition in phytoplankton resulted in deposition of surplus organic matter on the seafloor increasing the oxygen demand, with serious consequences for pelagic … This is a managed document. Statistical analyses showed that salinity and nutrients were the main factors affecting phytoplankton abundance and biomass. We analysed a unique (large) collection of phytoplankton monitoring data covering 86 coastal sites distributed over eight regions in North America and Europe, with the aim of investigating common patterns in the seasonal timing and species composition of the blooms.

The dynamics in the blooming concentrations of Pr. 1,4,6,8-10). Of the marine chronic toxicity data available, macroinvertebrates were the most sensitive species and dinoflagellates (Prorocentrum cordatum and Margalefidinium polykrikoides) were the least sensitive. Login. In addition, species diversity due to introduction of alien species is changing as well. 10). The marine environment of the surrounding sea around Jeju Island and Korean peninsula has been changing. The average length and width of nauplii were 0.473 and 0.150 mm, respectively. P. minimum reproduces asexually by binary fission. P. minimum can be confused with P. balticum; however, the former species differs by its larger size and different shape, and by having only one apical spine and a forked periflagellar collar ( Faust et al., 1999 ). Prorocentrum minimum is a bivalvate species often observed in valve view.

ABS compliance . The article reviews the up-to-date concepts of an ambiguous status of the widely spread, bloom-forming, potentially toxic mixotrophic dinoflagellates Prorocentrum cordatum in marine planktonic food webs, with special emphasis on the ecological prerequisites of their proliferation and possible scenarios underlying the development of harmful algal blooms and their top-down control in marine coastal waters. NB: Empty fields are hidden. In this study we examine how the projected climate change driven decrease in the Baltic Sea salinity can impact the growth, cell size and shape of the recently invaded dinoflagellate Prorocentrum cordatum. For more than 80 years there have existed two species Prorocentrum cordatum (Ostenfeld) Dodge (= Exuviaella cordata Ostenfeld, 1901, originally identified in Caspian Sea samples), and Prorocentrum minimum (Pavillard) Schiller (=Exuviaella minima Pavillard, 1916, the Gulf of Lion). This compound has frequently been used as a biomarker for the presence of (marine) algal matter in the environment, and is one of the ingredients for E number E499 .
