Most algae regularly experience periods of darkness ranging from a few hours to a few days.
During this time, they are unable to photosynthesize, and so must consume stored energy …

Diatoms, a key group of polar marine microbes, support highly productive ocean
ecosystems. Like all life on earth, diatoms do not live in isolation, and they are therefore …

Diatoms, the main eukaryotic phytoplankton of the polar marine regions, are essential for the
maintenance of food chains specific to Arctic and Antarctic ecosystems, and are …

Diatoms are phytoplanktonic organisms that grow successfully in the ocean where light
conditions are highly variable. Studies of the molecular mechanisms of light acclimation in …

Optical sensors for fluorescence of chlorophyll a (f-Chl a) and phycocyanin (f-PC) are
increasingly used as a proxy for biomass of algae and cyanobacteria, respectively. They …

Light underneath Antarctic sea‐ice is below detectable limits for up to 4 months of the year.
The ability of Antarctic sea‐ice diatoms to survive this prolonged darkness relies on their …

This study documents, for the first time, the abundance and species composition of protist
assemblages in Arctic sea ice during the dark winter period. Lack of knowledge of sea-ice …

Arctic microalgae experience long periods of continuous darkness during the polar night,
when they are unable to photosynthesize. Despite numerous studies on overwintering …

Antarctic algae are exposed to prolonged periods of extreme darkness due to polar night,
and coverage by ice and snow can extend such dark conditions to up to 10 months. A major …

In photosynthesis, a very small amount of the solar energy absorbed is transformed into
chemical energy, while the rest is wasted as heat and fluorescence. This excess energy can …
