Rhythms during the polar night: evidence of clock-gene oscillations in the Arctic scallop Chlamys islandica
Arctic regions are highly impacted by climate change and are characterized by drastic seasonal changes in light intensity and duration with extended periods of permanent light or darkness. Organisms use cyclic variations in light to synchronize daily and seasonal biological rhythms to anticipate cyc...
