A fungal pathogen provisionally identified as Neozygites cf. acaridis has recently been isolated from the Antarctic oribatid mite Alaskozetes antarcticus. The identification of the fungus is discussed with reference to […]
In 2005, Candida nivariensis, a yeast species genetically related to Candida glabrata, was described following its isolation from three patients in a single Spanish hospital. Between 2005 and 2006, 16 […]
We describe large-scale features of the Antarctic Circumpolar Current (ACC) in the Atlantic part of the Southern Ocean by merging Argo data and data obtained by novel animal-borne CTD sensors. […]
Aims: To exploit the cyanobacterial diversity of microbial mats growing in the benthic environment of Antarctic lakes for the discovery of novel antibiotic and antitumour activities. Methods and results: In […]
The Landsat Image Mosaic of Antarctica (LIMA) is the first true-color, high-spatial-resolution image of the seventh continent. It is constructed from nearly 1100 individually selected Landsat-7 ETM+ scenes. Each image […]
The Antarctic Treaty Summit, which will coincide with the fiftieth anniversary of the treaty’s signing, will be held at the Smithsonian Institution’s National Museum of Natural History, in Washington, D. […]
Interpretation of ice mass elevation changes observed by satellite altimetry demands quantification of the proportion of elevation change which is attributable to variations in firn densification. Detailed stratigraphic logging of […]
Predictions of sensitivity to climate change of polar benthos vary markedly depending on whether physiological or ecological/biodiversity criteria are considered. A realistic consensus view must be achieved as soon as […]
Studies of the recovery of the fauna following the 1967-70 eruptions at Deception Island, South Shetland Islands, have made it one of the best-studied marine sites of the Southern Ocean […]
Shelf and slope cryptofauna were sampled at the most northerly shelf environments within the Southern Ocean, Shag Rocks. The area is remarkably rich, with seven phyla, 10 classes, 40 families […]
It is widely believed that contemporary climate determines large-scale patterns of species richness. An alternative view proposes that species richness reflects biotic responses to historic climate changes. These competing “contemporary […]
A long-standing mystery in genome evolution is why short tandem repeats vary so much in length and frequency. Here, we test the hypothesis that body temperature acts to influence the […]
