We review current knowledge of non‐native marine species in the Antarctic region, the physical and physiological factors that resist establishment of non‐native marine species, changes to resistance under climate change, the role of legislation in limiting marine introductions, and the effect of increasing human activity on vectors and pathways ...

We emphasize the relevance of Antarctic fungi as sources of natural pigments and their potential in biotechnological application, with a deeper emphasis on UV radiation, Antarctic fungi as potential sources of pigments, pigments production by extremophilic fungi, the potential toxicity of derived pigments of fungi, pigment market, intellectual ...

The star shows the approximate location of the sampling point in relation to the Southern Antarctic Circumpolar Front (SACCF, in green), the Polar Front (PF, in yellow) and the maximum winter sea ice recorded in 2011 (Winter ice, in red).

Oct 22, 2009 · The red snow found in Langhovde, Antarctica, was investigated from several viewpoints. Various sizes of rounded red cells were observed in the red snow samples under microscopy. Pigment analysis demonstrated accumulation of astaxanthin in the red snow.

Nov 1, 2024 · IUCN Red List analysis shows 25 Antarctic species are candidates for protection. Climate change impacts mean the emperor penguin remains a priority for SPS status. SPS designation mechanisms for Antarctic terrestrial species should be reviewed.

Which is the major driver of PMC variability: Polar Vortex vs Solar Cycle? Did the Solar Cycle Signature Really Disappear? PMC Brightness correlation between lidar"

The Antarctic Treaty Consultative Meeting has taken steps to reduce microbial contamination of a small number of areas through the designation of ‘restricted’ zones within some Antarctic Specially Protected Areas (ASPAs) (e.g. ASPA 126 Byers Peninsula, Livingstone Island) .

This study has revealed that naturally red, exposed growth forms of Antarctic C. purpureus have higher levels of cell wall UVAC and lower intracellular UVAC as well as anthocyanin concentrations than its green, more shaded growth form. However, both colour morphs contained similar total UVAC concentrations.

Feb 14, 2025 · The striking red hues that occasionally stain the pristine white landscapes of Antarctica are a captivating phenomenon, often prompting questions about their origin and significance. This vibrant color, most famously seen at Blood Falls, is primarily due to the presence of iron salts that …

Sampling locations yielding invertebrate phylotypes in the Prince Charles Mountains, East Antarctica. (a) Prince Charles Mountains (PCMs) with sampling locations in overview, with (b) Mount Menzies (MM), (c) Mawson Escarpment (ME, including two locations north of the magnified area) and (d) Lake Terrasovoje (LT).Of 136 samples analysed in this study, 90 samples yielded invertebrate DNA, with ...
