Decoupling light harvesting, electron transport and carbon fixation during prolonged darkness supports rapid recovery upon re-illumination in the Arctic diatom Chaetoceros neogracilis
During winter in the Arctic marine ecosystem, diatoms have to survive long periods of darkness caused by low sun elevations and the presence of sea ice covered by snow. To better understand how diatoms survive...

Ultraviolet-B effects on photosystem II efficiency of natural phytoplankton communities from Antarctica
The impact of UVB on the Antarctic phytoplankton photosystem II repair cycle, involving the rapidly cycled D1 protein, was studied during summer 2002. On sunny and overcast days, phytoplankton (from 1-m depth)...
