A high-Arctic population of Pyla fusca (Lepidoptera, Pyralidae) on Svalbard?
Read more of: A high-Arctic population of Pyla fusca (Lepidoptera, Pyralidae) on Svalbard?Over 300 species of insect (including Collembola) are recorded from Svalbard. These include 11 species of Lepidoptera, the majority of which are occasional summer immigrants (Coulson and Refseth 2003). Those […]

What controls photochemical NO and NO2 production from Antarctic snow? Laboratory investigation assessing the wavelength and temperature dependence
Read more of: What controls photochemical NO and NO2 production from Antarctic snow? Laboratory investigation assessing the wavelength and temperature dependence[1] Laboratory experiments were conducted to determine the wavelength and temperature dependence of NO and NO2 release from Antarctic snow. This photochemically driven process has been observed during recent field […]

A placename geography for Antarctica
Read more of: A placename geography for AntarcticaPlacenames in Antarctica are uniquely complex. Antarctica’s distinctive political environment results in a situation where many national bodies confer names, but until recently there has been no coordination of this […]

Soil arthropods as indicators of water stress in Antarctic terrestrial habitats?
Read more of: Soil arthropods as indicators of water stress in Antarctic terrestrial habitats?Abiotic features of Antarctic terrestrial habitats, particularly low temperatures and limited availability of liquid water, strongly influence the ecophysiology and life histories of resident biota. However, while temperature regimes of […]

Maritime Antarctic climate change: signals from terrestrial biology
Read more of: Maritime Antarctic climate change: signals from terrestrial biologyThe simplicity of maritime Antarctic terrestrial ecosystems, combined with rapid changes in several environmental variables, creates a natural laboratory probably unparalleled worldwide in which to study biological consequences of climate […]

Long-term variation of the Antarctic Circumpolar Wave
Read more of: Long-term variation of the Antarctic Circumpolar Wave[1] During the period 1968-1999, the character of circum-Antarctic anomalies in sea level pressure, sea ice edge, and sea surface temperature changed substantially. An Antarctic Circumpolar Wave (ACW) is only […]

The genus Grimpoteuthis (Octopoda: Grimpoteuthidae) in the north-east Atlantic, with descriptions of three new species
Read more of: The genus Grimpoteuthis (Octopoda: Grimpoteuthidae) in the north-east Atlantic, with descriptions of three new speciesThe systematics and distribution of the cirrate octopod genus Grimpoteuthis in the north-east Atlantic are reviewed. Three new species are described and Grimpoteuthis wuelkeri (Grimpe, 1920) is redescribed. A new […]

Measurements of microbial protection from ultraviolet radiation in polar terrestrial microhabitats
Read more of: Measurements of microbial protection from ultraviolet radiation in polar terrestrial microhabitatsBiological dosimeters made from a monolayer of Bacillus subtilis spores were used to investigate the penetration of ultraviolet radiation into some widespread terrestrial microbial microhabitats at polar latitudes: at Mars […]
