Coastal Antarctic ecosystems feature long periods of sea ice cover, strong seasonality in primary production, and low biodiversity relative to marginal ice zone regions. There are few records of annual cycles of biodiversity and abundance of neritic Antarctic zooplankton…
Bdelloid rotifers are an important component of the biodiversity of ice-free regions of Antarctica. Despite this, knowledge of how to establish and maintain cultures, and optimal conditions for growth, is limited.
Aim … To map presence, absence and ignorance of Antarctic seabird breeding occupancy at the spatial resolution of ice-free habitat sites to identify knowledge gaps and inform management and conservation. Location … East Antarctica between longitudes 30°?E and 150°?E.
Antarctica, Earth's least understood and most remote continent, is threatened by human disturbances and climate-related changes, underscoring the imperative for biodiversity inventories to inform conservation. Antarctic ecosystems support unique species and genetic diversity…
The sub-Antarctic region between 45-60°S is primarily ocean. However, there are a few small isolated islands, most of which are currently facing the combined pressures of climate change and introduced species.

The major phospholipids of Halorubrum lacusprofundi grown at 25 1C were archaeol phosphatidylglycerol, archaeol … phosphatidylglycerylsulphate and archaeol phosphatidylglycerylphosphate methyl ester.Glycolipids included a monoglycosyl archaeol and the sulphate ester of a diglycosyl archaeol.
Green sulfur bacteria (GSB) (Chlorobiaceae) are primary producers that are important in global … carbon and sulfur cycling in natural environments. An almost complete genome sequence for a … single, dominant GSB species (‘C-Ace’)…
Zooplankton and benthic invertebrates are important components of polar lakes and often form the highest trophic level in the aquatic food web. Their biodiversity decreases towards high latitudes…
Paratrochammina minutissima n. sp. is described from … Abraxas and Ace Lakes in the Vestfold Hills, East … Antarctica. The species is characterized by very small size … (120 mm diameter), 4K chambers in the final whorl…
Evidence is provided from a sediment core from saline Abraxas Lake, Vestfold Hills, that indicates that the lake existed through the Last Glacial Maximum. It can therefore be concluded that at least part of the Vestfold Hills also remained ice-free through the Last Glacial Maximum…
A new species of rotifer, Rhinoglena kutikovae … n.sp. (Monogononta: Epiphanidae), is described from a … freshwater lake in the Bunger Hills, East Antarctica. The … new taxon is characterized by the following combination of … characters:
Antarctica is a continent locked in ice, with almost 99.7% of current terrain covered by permanent ice and snow, and clear evidence that, as recently as the Last Glacial Maximum (LGM), ice sheets were both thicker and much … more extensive than they are now.
Exopolysaccharides (EPS) may have an important role in … the Antarctic marine environment, possibly acting as ligands … for trace metal nutrients such as iron or providing … cryoprotection for growth at low temperature and high … salinity. Ten bacterial strains…
