The geochemistry of upland ponds, Taylor Valley, Antarctica
The McMurdo Dry Valleys of Antarctica are the largest ice-free region on the continent. These valleys contain numerous water bodies that receive seasonal melt from glaciers. For forty years, research emphasis has been placed on the larger water bodies, the permanent ice-covered lakes. We present results from the first study describing the geochemistry of ponds in the higher elevations of Taylor...
متن کاملDistribution of Siliceous-Walled Algae in Taylor Valley, Antarctica Lakes
The McMurdo Dry Valleys of Antarctica are a unique environment characterized by extreme lows in temperature and precipitation, which supports a low diversity microbial and multicellular fauna and flora. Terrestrial biomass is largely limited to soil microbes and mosses, while perennially ice-covered lakes host aerobic and anaerobic microbial communities, algae, and a low diversity eukaryotic fa...
متن کاملModeling the thickness of perennial ice covers on stratified lakes of the Taylor Valley, Antarctica
A 1-D ice cover model was developed to predict and constrain drivers of long-term ice thickness trends in chemically stratified lakes of Taylor Valley, Antarctica. The model is driven by surface radiative heat fluxes and heat fluxes from the underlying water column. The model successfully reproduced 16 a (between 1996 and 2012) of ice thickness changes for the west lobe of Lake Bonney (average ...
متن کاملMetabolic activity and diversity of cryoconites in the Taylor Valley, Antarctica
[1] Metabolic activity and biogeochemical diversity within cryoconites from the Canada, Commonwealth, Howard, and Hughes glaciers in the McMurdo Dry Valleys revealed the presence of a productive microbial refuge in this polar desert ecosystem. Fluorescent in situ hybridization showed a high percentage of Cytophaga-Flavobacteria cells in cryoconite sediments (87.2%), while b-Proteobacterial cell...
متن کاملThe Entrepreneurial Spirit of Rural Women: An Example from Iran
This study aimed to investigate the personality characteristics related to entrepreneurial spirit of rural women. The statistical population of the study included rural women in the central district of Nimrooz County in Sistan and Baluchistan Province (N=406). Krejcie and Morgan Table was used to determine the sample size. To this end, 186 participants were selected through stratified random sa...
