Increased cellular brevetoxins in the red tide dinoflagellate Karenia brevis under CO2 limitation of growth rate: Evolutionary implications and potential effects on bloom toxicity
Increased cellular brevetoxins Karenia brevis
2014/4/2
Karenia brevis blooms impair human health, marine ecosystems, and coastal economies in the Gulf of Mexico
via their production of carbon-based neurotoxins (brevetoxins), which contain no nitrogen (N)...
Lower Cretaceous palynostratigraphy and dinoflagellate cyst palaeoecology in the Siberian palaeobasin
Lower Cretaceous palynostratigraphy dinoflagellate cyst palaeoecology Siberian palaeobasin
2009/12/2
Palynological analysis of Lower Cretaceous (Berriasian-Barremian) sections from North Siberia allows definition of detailed dinocyst and sporepollen zonations, which are calibrated against the establi...
A Late Holocene climate history from the Malangen fjord,North Norway,based on dinoflagellate cysts
Late Holocene climate history Malangen fjord dinoflagellate cysts
2009/12/2
The Malangen fjord, a high Boreal/low Arctic fjord in northern Norway, reflects Atlantic Water heat flux. Studies of dinoflagellate cyst assemblages,reflecting the fjord surface water masses, have bee...
Dinoflagellate cyst assemblages inshore and offshore Svalbard reflecting their modern hydrography and climate
Dinoflagellate cyst assemblages inshore and offshore Svalbard modern hydrography climate
2009/12/2
Thirty-six seabed samples from inshore and offshore Svalbard and the northern part of the Barents Sea were collected for dinoflagellate cyst (dinocyst) analysis. Svalbard is an important locality repr...
Dinoflagellate bioluminescence in response to mechanical stimuli in water flows
Dinoflagellate bioluminescence mechanical stimuli water flows
2009/11/9
Bioluminescence of plankton organisms induced by water movements has long been observed and is still under investigations because of its great complexity. In particular, the exact mechanism occurring ...
Effect of fully characterized unsteady flow on population growth of the dinoflagellate Lingulodinium polyedrum
characterized unsteady dinoflagellate Lingulodinium polyedrum
2014/4/18
Dinoflagellate population growth is inhibited by fluid motion, which is typically characterized by some average
flow property, regardless if the flow is steady or unsteady. This study compares the ef...
Sex-related differential mortality of a marine copepod exposed to a toxic dinoflagellate
Sex-related differential mortality marine copepod exposed toxic dinoflagellate
2014/4/21
In this study we hypothesized that the sexes of the copepod Acartia hudsonica experience different mortalities when exposed to the toxic dinoflagellate Alexandrium fundyense. In laboratory experiments...
Chemical defense of the red tide dinoflagellate Karenia brevis against rotifer grazing
Chemical defense red tide dinoflagellate Karenia brevis against rotifer grazing
2014/4/22
In order to test whether phytoplankton such as the red tide dinoflagellate Karenia brevis negatively affect rotifer grazers and what mechanisms are involved in these interactions, we conducted laborat...
Newly discovered reproductive phenotypes of a marine copepod reveal the costs and advantages of resistance to a toxic dinoflagellate
Newly discovered reproductive phenotypes the costs and advantages of resistance
2014/4/22
We document for the first time toxin-resistant reproductive phenotypes of copepods and we describe a novel
procedure to identify these phenotypes. Individual copepods of the species Acartia hudsonica...
Dinosterols or dinocysts to estimate dinoflagellate contributions to marine sedimentary organic matter?
Dinosterols dinocysts dinoflagellate marine sedimentary organic matter
2014/4/21
Dinosterol (4α,23,24-trimethyl-5α-cholest-22E-en-3β-ol) is frequently used as an alternative to dinoflagellate cyst (dinocyst) counting in paleoceanography to assess dinoflagellate inputs to marine se...
