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 […]
[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 […]
Placenames 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 […]
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 […]
The 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 […]
[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 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 […]
Biological 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 […]
Impact structures are a rare habitat on Earth. However, where they do occur they can potentially have an important influence on the local ecology. Some of the types of habitat […]
