Antarctic Terrestrial Microbiology
@inproceedings{Cowan2014AntarcticTM, title={Antarctic Terrestrial Microbiology}, author={Don A. Cowan}, booktitle={Springer Berlin Heidelberg}, year={2014} }
Ice-free soils might represent a very small proportion of the total land area of the Antarctic continent, but they harbour substantial and diverse microbial populations. Only since the advent of modern molecular phylogenetic methods has the true complexity of Antarctic soil microbiology been apparent. With this discovery has come a series of ‘revelations’: Antarctic soil communities are highly structured and physiologically complex, they are important functional components of the different soil…

Geomicrobiological Heterogeneity of Lithic Habitats in the Extreme Environment of Antarctic Nunataks: A Potential Early Mars Analog
- Environmental ScienceFrontiers in Microbiology
- 2021
Investigating the geomicrobiology of the permanently exposed lithic substrates of nunataks from Livingston Island finds stable isotopic ratios of total carbon and nitrogen, soluble anions concentrations, and the detection of proteins involved in key metabolisms via the Life Detector Chip suggest that microbial primary production has a pivotal role in nutrient cycling at these exposed areas with limited deposition of nutrients.

Current literature on the ecology, and the functional role played by cyanobacteria in various Arctic and Antarctic environments are reviewed, focusing on the ecological importance of cyanobacterial communities in Polar Regions and what is known regarding the toxins they produce.
Heterogeneity of Microbial Communities in Soils From the Antarctic Peninsula Region

The results suggest that in ice-free soils exposed for longer periods of time (millennia) microbial communities are significantly different along the soil profiles, however, in recently deglaciated soils the communities are not differentAlong the soil profile.
Hypolithic communities shape soils and organic matter reservoirs in the ice-free landscapes of East Antarctica
- Environmental ScienceScientific Reports

It is demonstrated that cryptic hypolithic varieties of BSC in the Larsemann Hills of East Antarctica contribute to the buildup of soil organic matter and produce several types of continuous organogenous horizons within the topsoil with documented clusters of at least 100 m 2 .

Functional Diversity of Microbial Communities in the McMurdo Dry Valleys, Antarctica
- Environmental Science
- 2016
The high throughput 16S rRNA gene sequencing showed Cyanobacteria, Actinobacteria and Proteobacteria were relatively dominant in hypolithic and soil communities, and these phyla also displayed the greatest functional diversity, suggesting that the metabolic plasticity for these taxa may be an important factor in their role as keystone species in these communities.

Microbial community composition in soils of Northern Victoria Land, Antarctica.

This work investigates soil microbial communities from low- and high-productivity habitats in an isolated Antarctic location to determine how the soil environment impacts microbial community composition and structure and adds to the recent literature suggesting that there is a higher biodiversity within Antarctic soils than previously expected.
Shifts in soil microorganisms in response to warming are consistent across a range of Antarctic environments
- Environmental ScienceThe ISME Journal
- 2012
This work finds significant increases in the abundance of fungi and bacteria and in the Alphaproteobacteria-to-Acidobacteria ratio, which could result in an increase in soil respiration and shifts toward generalist bacterial communities following warming weakened the linkage between the bacterial taxonomic and functional richness.
