Carbon-fixation rates and associated microbial communities residing in arid and ephemerally wet Antarctic Dry Valley soils
(Frontiers, 2015)Carbon-fixation is a critical process in severely oligotrophic Antarctic Dry Valley (DV) soils and may represent the major source of carbon in these arid environments. However, rates of C-fixation in DVs are currently ... -
Diverse and highly active diazotrophic assemblages inhabit ephemerally wetted soils of the Antarctic Dry Valleys
(Blackwell Publishing Ltd, 2012)Eolian transport of biomass from ephemerally wetted soils, associated with summer glacial meltwater runoffs and lake edges, to low-productivity areas of the Antarctic Dry Valleys (DV) has been postulated to be an important ... -
Microbial community composition of transiently wetted Antarctic Dry Valley soils
(FRONTIERS RESEARCH FOUNDATION, 2015-01-28)During the summer months, wet (hyporheic) soils associated with ephemeral streams and lake edges in the Antarctic Dry Valleys (DVs) become hotspots of biological activity and are hypothesized to be an important source of ... -
Rapid microbial dynamics in response to an induced wetting event in Antarctic Dry Valley Soils
(Frontiers Media SA, 2019)The cold deserts of the McMurdo Dry Valleys (MDV), Antarctica, host a high level of microbial diversity. Microbial composition and biomass in arid vs. ephemerally wetted regions are distinctly different, with wetted ... -
The microbial ecology and colonisation of surfaces in selected hot springs - a molecular-and culture-based approach
(The University of Waikato, 2005)Traditionally, culture-based approaches have been used to investigate the microbial ecology of thermal habitats. The emergence of alternate molecular approaches based on DNA sequences has shown that terrestrial thermal ...
