Is Ambient Light during the High Arctic Polar Night Sufficient to Act as a Visual Cue for Zooplankton?
Publisher's PDF. The light regime is an ecologically important factor in pelagic habitats, influencing a range of biological processes. However, the availability and importance of light to these processes in high Arctic zooplankton communities during periods of 'complete' darkness (po...

Publisher's PDF. The light regime is an ecologically important factor in pelagic habitats, influencing a range of biological processes.
