Description
Summary:This work examines the microbial communities in two extremely acidic habitats:the terrestrial environment of the Paint Pots Mound (Kootenay National Park, BritishColumbia, Canada) and the sediments of an ultra-acidic lake in the Smoking Hills (CapeBathurst, Northwest Territories, Canada) area. While the acidification of both locationsoriginates from the natural pyrite ore oxidation processes, the sites show a dramaticcontrast in microbial compositions, function, complexity, and diversity. The chemicalcomposition of the sites is suggestive of that of acid mine drainage (AMD) systems;however, the habitats of the Paint Pots and Smoking Hills are pristine, unlike the majorityof AMD, and therefore offer a unique opportunity in microbial ecology research.The microbial communities of the sites are explored using metagenomics andstable isotope probing. Microbial load and diversity in both locations were low. However,despite their high acidity, metal, and sulfate content similarities, the habitats hostedcontrasting ...
