Genetic switch lets marine diatoms do less work at higher CO2
Genetic switch marine diatoms higher CO2
2015/6/18
Diatoms in the world’s oceans exhale more oxygen than all the world’s rainforests. These tiny drifting algae generate about 20 percent of the oxygen produced on Earth each year, and invisibly recycle ...
The effects of Cu and Fe availability on the growth and Cu:C ratios of marine diatoms
The effects of Cu and Fe availability on the growth and Cu:C ratios of marine diatoms
2014/4/21
We investigated the effects of copper (Cu) and iron (Fe) availability on the growth rates, cellular Cu content, and steady-state Cu uptake rates of eight species of centric diatoms (coastal and oceani...
Extracellular production of superoxide by marine diatoms: Contrasting effects on iron redox chemistry and bioavailability
Extracellular production of superoxide marine diatoms Contrasting effects iron redox chemistry and bioavailability
2014/5/9
We report the extracellular production of superoxide in cultures of the marine diatoms Thalassiosira weissflogii and Thalassiosira pseudonana. In EDTA-buffered media with ~45 pmol L-1 iron (Fe)(III)',...
Effect of large marine diatoms growing at low light on episodic new production
large marine diatoms growing low light episodic new production
2014/5/20
Mesoscale eddies have been shown to be a common feature of open ocean regions such as the Sargasso Sea. By lifting nutrients up to the lower portions of the euphotic zone, these eddies can cause episo...
Light absorption and size scaling of light-limited metabolism in marine diatoms
Light absorption size scaling light-limited metabolism marine diatoms
2014/5/30
Previous studies have found that the size-scaling exponent of metabolic rates in unicellular algae often deviates from the exponent of -1/4 usually found for heterotrophs. This study confirms a signif...
