First successful culture of the marine dinoflagellate Dinophysis acuminata
The dinoflagellate genus Dinophysis in- cludes several species that cause diarrhetic shellfish poi- soning, none of which have yet been established in cul- ture. We report on the maintenance of
PARASITISM OF PHOTOSYNTHETIC DINOFLAGELLATES BY THREE STRAINS OF AMOEBOPHRYA (DINOPHYTA): PARASITE SURVIVAL, INFECTIVITY, GENERATION TIME, AND HOST SPECIFICITY1
TLDR
Results suggest that Amoebophrya strains have evolved somewhat divergent survival strategies that may encompass sexuality, heterotrophy during the “free‐living” dinospore stage, and dormancy.
Parasites and Phytoplankton, with Special Emphasis on Dinoflagellate Infections1
TLDR
Parasitism needs to be carefully considered in developing concepts about plankton dynamics and the flow of material in marine food webs, as work indicates that these parasites can have significant impacts on host physiology, behavior, and bloom dynamics.
Growth and grazing responses of the mixotrophic dinoflagellate Dinophysis acuminata as functions of light intensity and prey concentration
TLDR
Results indicate that Dinophysis species are typically prey-limited in the field, and suggest that D. acuminata is an obligate mixotroph that requires both light and prey for long-term survival.
PLASTID DYNAMICS DURING SURVIVAL OF DINOPHYSIS CAUDATA WITHOUT ITS CILIATE PREY 1
TLDR
The results indicate that D. caudata is an intriguing protist that would represent an interesting evolutionary adaptation with regard to photosynthesis as well as help us to better understand plastid evolution in eukaryotes.
DINOPHYSIS CAUDATA (DINOPHYCEAE) SEQUESTERS AND RETAINS PLASTIDS FROM THE MIXOTROPHIC CILIATE PREY MESODINIUM RUBRUM 1
TLDR
The results for D. caudata resolve the apparent discrepancy between morphological and molecular data by showing that plastids acquired when feeding on M. rubrum are structurally modified and retained as stellate compound chloroplasts characteristic of Dinophysis species.
Phytoplankton biomass and primary production in the marginal ice zone of the northwestern Weddell Sea during austral summer
TLDR
A comparison between the historical productivity data and the data shows that the most productive regions in the Southern Ocean are shelf waters and the marginal ice zone, with emerging evidence of frontal regions as another major productive site.
UREA DECOMPOSITION ACTIVITIES IN AN AMMONIUM ENRICHED FRESHWATER POND
TLDR
It is suggested that urea decomposition activity in an ammonium enriched freshwater pond is significantly elevated and controlled by the urea concentration, and that bactena might contribute substantially to u Andrea decomposition rate in a hypertrophic freshwater pond.
Antarctic Phytoplankton Assemblages in the Marginal Ice Zone of the Northwestern Weddell Sea
The waters around the northern tip of the Antarctic Peninsula show complex patterns of water circulation due to mixing of diverse water masses. Physicochemical properties of the different water types
