News and Updates:

In a new publication, the Schuurlab shows that more carbon is being released from thawed permafrost than previously thought. The new paper in Nature Geoscience introduces a new way to track soil carbon in permafrost, which changes the understanding of how environmental change influences ecosystem carbon storage. The experiment builds on a long-term permafrost tundra warming study Schuur and collaborators are doing in Alaska.

New paper in PNAS

Rising temperatures in the tundra of the Earth’s northern latitudes could affect microbial communities in ways likely to increase their production of greenhouse gases methane and carbon dioxide, a new study of experimentally warmed Alaskan soil suggests. 

The new study was supported by the U.S. Department of Energy and the National Science Foundation, and reported July 8 in the early edition of the journal Proceedings of the National Academy of Sciences. Researchers from the University of Oklahoma, Michigan State University and Northern Arizona University collaborated with Georgia Tech on the study.

EOS Research Spotlight features the work 'Adding Depth to Our Understanding of Nitrogen Dynamics in Permafrost Soils' of former PhD student Verity Salmon. Read the Research Spotlight here (November 2018).

The article describes Salmon's work: The study offers critical insights into how warming temperatures in the Arctic could dramatically increase permafrost thaw and initiate profound changes in carbon and nitrogen cycling in tundra ecosystems. (Journal of Geophysical Research: Biogeosciences, 2018). Read the full paper here.

 

Christina Schädel and Ted Schuur are featured in an NAU news article (April 2018).

The article describes their most recent publication in the Proceedings of the National Acadmey of Sciences. The findings of the study, organized by the Permafrost Carbon Network, suggest that putting more effective greenhouse gas controls in place for the rest of this century could help mitigate the effects of climate change on the release of carbon from thawing soils of the northern permafrost region.

The research in our lab focuses on:

  • the interactions between terrestrial ecosystems and global change
  • the exchange of carbon between plants, soils, and the atmosphere
  • understanding the response of terrestrial ecosystems to changes in climate and disturbance regimes
  • responses of arctic ecosystems to climate change
  • radiocarbon dating
