  • Antarctic Dry Valley mineral soils contain unexpectedly high levels of microbial biomass 

    Cowan, Donald A.; Mamais, A.; Russell, Nick A.; Sheppard, Devon M. (Springer Verlag, 2002)
    We have applied bioluminescent ATP detection methods to microbial enumeration in Antarctic Dry Valley mineral soils, and validated our ATP data by two independent methods. We have demonstrated that ATP measurement is ...
  • Dissemination and survival of non-indigenous bacterial genomes in pristine Antarctic environments. 

    Ah Tow, Lemese; Cowan, Donald A. (Springer Verlag, 2005)
    Continental Antarctic is perceived as a largely pristine environment, although certain localized regions (e.g., parts of the Ross Dependency Dry Valleys) are relatively heavy impacted by human activities. The procedures ...
  • Endangered Antarctic microbial communities 

    Cowan, Donald A.; Ah Tow, Lemese (Annual Reviews, 2004)
    The Antarctic continent harbors a range of specialized and sometimes highly localized microbial biotopes. These include biotopes associated with desiccated mineral soils, rich ornithogenic soils, glacial and sea ice, ...
  • High 16S rDNA bacterial diversity in glacial meltwater lake sediment, Bratina Island, Antarctica 

    Sjoling, Sara; Cowan, Donald A. (Springer Verlag, 2003)
    The microbial diversity in maritime meltwater pond sediments from Bratina Island, Ross Sea, Antarctica was investigated by 16S rDNA-dependent molecular phylogeny. Investigations of the vertical distribution, phylogenetic ...
  • Micro-Eukaryotic diversity in Hypolithons from Miers Valley, Antarctica 

    Gokul, Jarishma K.; Valverde, Angel; Tuffin, Marla; Cary, Stephen Craig; Cowan, Don A. (Multidisciplinary Digital Publishing Institute (MDPI), 2013)
    The discovery of extensive and complex hypolithic communities in both cold and hot deserts has raised many questions regarding their ecology, biodiversity and relevance in terms of regional productivity. However, most ...
  • Non-specificity of Staphylococcus generic primers 

    Ah Tow, Lemese; Cowan, Donald A. (Society for General Microbiology, 2003)
    Our results allow us to conclude that there appears to be significant conservation between the tuf genes of Planococcus, Planomicrobium and Staphylococcus spp., and that although the primer set TstaG422/TStag765 has ...
  • PCR-based detection of non-indigenous microorganisms in ‘pristine’ environments 

    Baker, Gillian; Ah Tow, Lemese; Cowan, Donald A. (Elsevier, 2003)
    PCR-based technologies are widely employed for the detection of specific microorganisms, and may be applied to the identification of non-indigenous microorganisms in ‘pristine’ environments. For ‘pristine’ environments ...
