Unexpected Levels of Biological Activity during the Polar Night Offer New Perspectives on a Warming Arctic
The current understanding of Arctic ecosystems is deeply rooted in the classical view of a bottom-up controlled system with strong physical forcing and seasonality in primary-production regimes. Consequently, the Arctic polar night is commonly disregarded as a time of year when biological activities...
