In the Anthropocene, in which we now live, climate change is impacting most life on Earth.
Microorganisms support the existence of all higher trophic life forms. To understand how …

Much of the Earth's surface, both marine and terrestrial, is either periodically or permanently
cold. Although habitats that are largely or continuously frozen are generally considered to be …

Important findings from the second decade of the 21st century on the impact of
environmental change on biological processes in the Antarctic were synthesised by 26 …

Rapid warming in the highly productive western Antarctic Peninsula (WAP) region of the
Southern Ocean has affected multiple trophic levels, yet viral influences on microbial …

Bacterioplankton (bacteria and archaea) are indispensable regulators of global element
cycles owing to their unique ability to decompose and remineralize dissolved organic matter …

The extent, duration, and seasonality of sea ice and glacial discharge strongly influence
Antarctic marine ecosystems. Most organisms' life cycles in this region are attuned to ice …

Heterotrophic marine bacteria play key roles in remineralizing organic matter generated
from primary production. However, far more is known about which groups are dominant than …

Southern Ocean primary productivity plays a key role in global ocean biogeochemistry and
climate. At the Southern Ocean sea ice edge in coastal McMurdo Sound, we observed …

Global warming in ocean ecosystems alters temperature, acidification, oxygen content,
circulation, stratification, and nutrient inputs. Microorganisms play a dominant role in global …

Despite the high abundance of Archaea in the global ocean, their metabolism and
biogeochemical roles remain largely unresolved. We investigated the population dynamics …
