Continent-wide risk assessment for the establishment of nonindigenous species in Antarctica
An evidence-based assessment demonstrates which parts of Antarctica are at growing risk from alien species that may become invasive and provides the means to mitigate this threat now and into the future as the continent's climate changes. Expand
Post-glacial regional climate variability along the East Antarctic coastal margin - evidence from shallow marine and coastal terrestrial records
We review the post-glacial climate variability along the East Antarctic coastline using terrestrial and shallow marine geological records and compare these reconstructions with data from elsewhere.Expand
Spatial and temporal variability of snow accumulation rate on the East Antarctic ice divide between Dome Fuji and EPICA DML
Abstract. To better understand the spatio-temporal variability of the glaciological environment in Dronning Maud Land (DML), East Antarctica, a 2800-km-long Japanese-Swedish traverse was carried out.Expand
Contribution of hydrogen bonds to protein stability
The goal was to gain a better understanding of the contribution of the burial of polar groups and their hydrogen bonds to the conformational stability of proteins, and to compare the results with previous studies of similar mutants in other proteins. Expand
Eukaryotic phylotypes in aquatic moss pillars inhabiting a freshwater lake in East Antarctica, based on 18S rRNA gene analysis
The 18S rRNA gene-based profiles demonstrated that redox-related factors may control distribution of some eukaryotic microbes in a whole moss pillar and suggested that fungi may contribute to carbon cycling in the moss pillar as parasites or decomposers. Expand
Phytoplankton blooms under dim and cold conditions in freshwater lakes of East Antarctica
Differences in the autumn and spring increases suggest that the spring algal community is more shade-adapted than the autumn algalcommunity, and Antarctic phytoplankton appears especially adapted to low-light levels and inhibited by strong light regimes. Expand
Ideal Osmotic Spaces for Chlorobionts or Cyanobionts Are Differentially Realized by Lichenized Fungi1[W][OPEN]
Through the analysis of cellular osmolarity, it was clearly shown that photobionts retain their original properties as free-living organisms even after lichenization. Expand
Distribution of aquatic mosses in the Soya Coast region, East Antarctica
The distribution of aquatic mosses among 1lakes in the Sôya Coast region, East Antarctica, was surveyed. Two species of mosses, Bryum pseudotriquetrum and Leptobryum sp. were found at the bottom ofExpand
Molecular and morphological analysis of an Antarctic tardigrade, Acutuncus antarcticus
A species of tardigrade from moss samples collected from Langhovde and Skarvsnes, near Syowa station, East Antarctic, is isolated, identical to that of Acutuncus antarcticus from King George island, South Shetland islands, and Morphological analyses via both light and scanning electron microscopy show general agreement with characteristics of A. antarctica. Expand
Recovery and reproduction of an Antarctic tardigrade retrieved from a moss sample frozen for over 30 years.
A considerable extension of the known length of long-term survival of tardigrades recorded in this study is interpreted as being associated with the minimum oxidative damage likely to have resulted from storage under stable frozen conditions. Expand
