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)...
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...
Assessing environmental control on dinoflagellate cyst distribution in surface sediments of the Benguela upwelling region (eastern South Atlantic)
environmental control dinoflagellate cyst distribution surface sediments the Benguela upwelling region
2014/4/21
Organic-walled dinoflagellate cyst assemblages in surface sediments of the Benguela Current Upwelling System (eastern South Atlantic) show geographic patterns that cannot entirely originate from cyst ...
Effect of turbulence on sedimentation and net population growth of the dinoflagellate Ceratium tripos and interactions with its predator, Fragilidium subglobosum
Effect of turbulence on sedimentation and net population growth of the dinoflagellate Ceratium tripos and interactions with its predator, Fragilidium subglobosum
2014/5/13
We investigated the effect of natural levels of turbulence on the vertical distribution and net population growth of the dinoflagellate Ceratium tripos and on the interaction with its predator, the mi...
Does the red tide dinoflagellate Karenia brevis use allelopathy to outcompete other phytoplankton?
red tide dinoflagellate Karenia brevis allelopathy outcompete other phytoplankton
2014/5/9
Monospecific blooms of phytoplankton can disrupt pelagic communities and negatively affect human health and economies. Interspecific competition may play an important role in promoting blooms, and so ...
