Marine photosynthetic eukaryotes in polar systems: Unveiling phytoplankton diversity and composition in Antarctic waters

Antarctic waters are a particular marine environment mainly due to the strong seasonal variations that various parameters are subject to, like light availability and temperature. As in all oceanographic regions, food webs are sustained by photosynthetic microorganisms, which in the case of Antarctic...

As in all oceanographic regions, food webs are sustained by photosynthetic microorganisms, which in the case of Antarctic environments seem to be strongly dominated by its eukaryote component. Assessing the ecological role of photosynthetic microbial eukaryotes requires a basic knowledge of their diversity and community composition. This review integrates the available information regarding this component of Antarctic phytoplankton as a way to unveil its diversity and how they respond to the strong changes that occur in this environment.
