Correlation and interaction between temperature and freeze-thaw in representative regions of Antarctica

International Journal of Digital Earth, 2022
As the most sensitive and direct indicator of global climate change, the freezing and thawing of the Antarctic ice sheet is of great significance for research on surface mass and energy balance.

Global biogeographic patterns in bipolar moss species [PDF]

Royal Society Open Science, 2017
A bipolar disjunction is an extreme, yet common, biogeographic pattern in non-vascular plants, yet its underlying mechanisms (vicariance or long-distance dispersal), origin and timing remain poorly understood.

A Tropospheric Assessment of the ERA-40, NCEP, and JRA-25 Global Reanalyses in the Polar Regions [PDF]

, 2007
The reliability of the global reanalyses in the polar regions is investigated. The overview stems from an April 2006 Scientific Committee on Antarctic Research (SCAR) workshop on the performance of global reanalyses in high latitudes held at the British ...

Assessment of Cryospheric Parameters Over the Himalaya and Antarctic Regions using SCATSAT-1 Enhanced Resolution Data

Current Science, 2019
Antarctica is the focus of scientific studies considering the largest reservoir of terrestrial water in the form of ice and doubling of ice area during winter due to sea-ice growth.

Low genetic diversity in Antarctic populations of the lichen-forming ascomycete Cetraria aculeata and its photobiont [PDF]

Polar Research, 2012
Lichens, symbiotic associations of fungi (mycobionts) and green algae or cyanobacteria (photobionts), are poikilohydric organisms that are particularly well adapted to withstand adverse environmental conditions.

The first comprehensive description of the biodiversity and biogeography of Antarctic and Sub-Antarctic intertidal communities [PDF]

, 2016
Aim To describe the distribution of biodiversity and biogeographical patterns of intertidal organisms in southern temperate and polar waters. We hypothesized that there would be differences in community structure between the Antarctic, which is most ...

Multidecadal warming of Antarctic waters [PDF]

, 2014
Decadal trends in the properties of seawater adjacent to Antarctica are poorly known, and the mechanisms responsible for such changes are uncertain. Antarctic ice sheet mass loss is largely driven by ice shelf basal melt, which is influenced by ocean-ice

Evidence for strong environmental control on bacterial microbiomes of Antarctic springtails

Scientific Reports, 2021
Collembola are a key component of the soil biota globally, playing an important role in community and ecosystem dynamics. Equally significant are their associated microbiomes, that can contribute to key metabolic functions.

Antarctic extreme events

Frontiers in Environmental Science, 2023
There is increasing evidence that fossil-fuel burning, and consequential global heating of 1.1°C to date, has led to the increased occurrence and severity of extreme environmental events.
