    Through a collaboration with SPAWAR (Dawn Lawson), SERG (Tom Zink), the USGS and others, we had the opportunity to study the effects of a prescribed burn experiment on soil microbial communities in a perennial grassland on San Clemente Island. Prescribed fire is a potential tool for controlling exotic annual grasses and restoring the native perennial…

Our AGU Poster describes a snow microbiology research project and how the data were translated into oil paintings by Kim Reasor, shown below (click on her name to see…

  • Iron reduction in soils of the Alaskan Arctic

    Iron reduction in soils of the Alaskan Arctic

    From 2009-2012, we were funded by the NSF to study the importance of iron (Fe(III)) reduction as a dominant anaerobic process in soils of the Arctic Coastal Plain, near Barrow, Alaska. Fe(III) can serve as an alternative electron acceptor for anaerobic respiration when oxygen is depleted. What is special about Fe(III) is that it generally…
