Marine microbial eukaryotes are important primary producers and play critical roles in key
biogeochemical cycles. Recent advances in sequencing technology have focused attention …

Surveying microbial diversity and function is accomplished by combining complementary
molecular tools. Among them, metagenomics is a PCR free approach that contains all …

Ocean circulation and the formation and upwelling of water masses in the Southern Ocean
play a critical role in the exchange of heat and carbon with the atmosphere over glacial …

Polar oceans belong to the most productive and rapidly changing environments, yet our
understanding of this fragile ecosystem remains limited. Here we present an analysis of a …

Sea ice is a crucial component of the Arctic climate system, yet the tools to document the
evolution of sea ice conditions on historical and geological time scales are few and have …

Artificial reefs (ARs) are widely used for biodiversity conservation and coastal habitat
restoration. Although protists play an important ecological role in marine ecosystems, the …

Introduction of non-indigenous microbial organisms is forecast to pose a significant threat to
the northern Antarctic Peninsula (NAP) marine environments, but reliable data are still …

Planktonic protists are an essential component of marine pelagic ecosystems where they
mediate important trophic and biogeochemical functions. Although these functions are …

The Andvord fjord in the West Antarctic Peninsula (WAP) is known for its productivity and
abundant megafauna. Nevertheless, seasonal patterns of the molecular diversity and …

The deep sea is one of the largest but least understood ecosystems on earth. Knowledge
about the diversity and distribution patterns as well as drivers of microbial eukaryote …
