    Changes in microbial communities along redox gradients…

    In collaboration with Janet Jansson (now with PNNL), we published this study in Environmental Microbiology Reports, showing that redox gradients are a dominant force in structuring microbial communities in wet Arctic tundra soils.

  • Methane suppression by iron and humic acids in soils of the Arctic Coastal Plain

    Methane suppression by iron and humic acids in soils of the Arctic Coastal Plain

    Recently graduated Ph.D. Student, Kimberly Miller, published part of her dissertation in Soil Biology and Biochemistry, showing that the addition of alternative electron acceptors, ferric iron and humic acid, reduced methane fluxes in the tundra near Barrow, Alaska. This work resulted from our NSF grant to study the significance of iron and humic substances in…
