The Baltic Sea is one of the world’s largest
brackish water basins and is traditionally considered to be
species poor. Here, we assessed the diversity of the nanosized
eukaryotic microbial wintertime community, using
molecular ecological methods based on sequencing of
small-subunit ribosomal RNA gene clone libraries. The
results demonstrate that a rich community of small eukaryotes
inhabits the Baltic Sea ice and water during winter.
The community was dominated by alveolates and stramenopiles.
Ciliates and cercozoans were the richest groups
present, while in contrast to previous studies, diatoms
showed a lower richness than expected. Furthermore, fungi
and parasitic Syndiniales were present both in the water and
in the sea ice. Some of the organisms in the sea-ice community
were active, based on the RNA data, but a number of
organisms were inactive or remnants from the freezing process.
The results demonstrate that the sea-ice communities
in the Baltic Sea are highly diverse and that water and ice of
diVerent ages include diVerent protistan assemblages. Our
study emphasizes the potential loss in biodiversity through
diminishing ice cover as a result of climate change.
