Phaeocystis antarctica is a key planktonic plant species in the Antarctic ecosystem. Its complex life cycle involves solitary and colonial morphotypes.
In parts of the Southern Ocean it must cope with freezing water temperature and complete darkness during the austral winter. To understand how this species thrives in such an extreme environment, we conducted a series of experiments in the United States McMurdo Station using natural P. antarctica assemblages.
Our results showed that Phaeocystis antarctica can survive a long period of darkness and freezing, and quickly resume its photosynthetic capacity and growth upon return to spring-time conditions.
