Mice living in tussock grass on a remote headland of the South Atlantic island of South Georgia (54°S) where the mean temperature is less than 2°C and the monthly average […]
Antarctica is one of the least anthropogenically-impacted areas of the world. Metal sources to the marine environment include localised activities of research stations and glacial meltwater containing metals of lithogenic […]
The cold tolerance mechanism of the Antarctic terrestrial mite Alaskozetes antarcticus (Michael) was investigated in cultured animals. Freezing is fatal in this species and winter survival occurs by means of […]
1. Determinations of live weight-specific oxygen consumption (metabolic rate) in adults of the Antarctic terrestrial mite Alaskozetes antarcticus (Michael) showed that starvation resulted in metabolic suppression. 2. Food materials were […]
The temperate cryptostigmatid mite Humerobates rostrolamellatus Grandjean tolerates temperatures below -20°C by supercooling. Glycerol is present in these animals after acclimation at 0°C. The significance of these findings is briefly […]
The Signy Island terrestrial reference sites epitomize unpolluted maritime Antarctic tundra. The extreme transition from the harsh Antarctic winter to the milder summer facilitates studies of the effects of freeze-thaw […]
During winter (1973), a very pure natural population of the diatom Navicula glaciei Van Heurck occurred in dense concentrations (up to 244 mg·m−2 chlorophyll a) in the sea ice at […]
The high-latitude atmosphere is a dynamic region with processes that respond to forcing from the Sun, magnetosphere, neutral atmosphere, and ionosphere. Historically, the dominance of magnetosphere–ionosphere interactions has motivated upper […]
Climate change at the Western Antarctic Peninsula (WAP) is predicted to cause major changes in phytoplankton community composition, however, detailed seasonal field data remain limited and it is largely unknown […]
