Sources of elevated heavy metal concentrations in sediments and benthic marine invertebrates of the western Antarctic Peninsula
Read more of: Sources of elevated heavy metal concentrations in sediments and benthic marine invertebrates of the western Antarctic PeninsulaAntarctica 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 […]

Experimental studies on the cold tolerance of Alaskozetes antarcticus
Read more of: Experimental studies on the cold tolerance of Alaskozetes antarcticusThe 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 […]

Some factors affecting metabolic rate in an Antarctic mite
Read more of: Some factors affecting metabolic rate in an Antarctic mite1. 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 […]

Cold hardiness in a temperate cryptostigmatid mite
Read more of: Cold hardiness in a temperate cryptostigmatid miteThe 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 […]

Seasonal fluctuations in microbial activity in Antarctic moss peat
Read more of: Seasonal fluctuations in microbial activity in Antarctic moss peatThe 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 […]
