The Antarctic marine environment, although rich in life, is predicted to experience rapid and significant effects from climate change. Despite a revolution in the approaches used to document biodiversity…
Genetic diversity is essential for maintaining healthy populations and ecosystems. Several approaches have recently been … developed to evaluate population genetic trends without necessarily collecting new genetic data. Such "genetic diversity … indicators" enable rapid…
Genomic adaptation and introgression can occur during the speciation process, enabling species to diverge in their frequencies of adaptive alleles or acquire new alleles that may promote adaptation to environmental changes.
Under the recently adopted Kunming-Montreal Global Biodiversity Framework, 196 Parties committed to reporting the status of genetic diversity for all species. To facilitate reporting, three genetic diversity indicators were developed…
In this paper, we report on fish by-catch during exploratory fishing activities undertaken in Divisions 58.4.1 and 58.4.2 during the period 2014 to 2020. Fish by-catch comprised 12 species or groups of species. In 2019 and 2020, exploratory fishing occurred exclusively in research block 58.4.
In this paper, we report on fish bycatch during exploratory fishing activities undertaken in Divisions 58.4.1 and 58.4.2 during the period 2016 to 2022. Fish bycatch was composed of at least 14 species or species groups. In 2021 and 2022, exploratory fishing occurred in Division 58.4.2 only…
Poa annua is the most widespread alien species in the sub-Antarctic, occurring on all major island groups and is invasive and spreading on the Antarctic Peninsula. P. annua colonises areas disturbed by human activity, seal wallows, penguin rookeries and glacial moraines.
As zooplankton is an important food source for consumers, and a major source of recruits to the benthic community, impacts on sensitive zooplankton communities have the potential to significantly alter nearshore marine ecosystems in Antarctica.
Understanding the sensitivity of Antarctic organisms to metal exposure is essential … for developing Antarctic specific Environmental Guidelines to manage contamination risks. For … the first time…
PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed 2.5-m optical/ … infrared telescope to be located at Dome C on the Antarctic plateau. Conditions at Dome C are known to … be exceptional for astronomy. The seeing (above ¡30m height), coherence time…
PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed 2.5-m optical/ … infrared telescope to be located at Dome C on the Antarctic plateau. The atmospheric conditions at Dome C … deliver a high sensitivity, high photometric precision, wide-field, high spatial resolution…
Compared to temperate and tropical relatives, some high-latitude marine species are large-bodied, a phenomenon known as polar gigantism. A leading hypothesis on the physiological basis of gigantism … posits that, in polar water…
PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed Australian/European optical/infrared … telescope for Dome C on the Antarctic Plateau, with target first light in 2012. The proposed telescope is 2.4m diameter, with overall focal ratio f/10…
