Journal ArticleDOI
Permafrost thaw and soil moisture driving CO2 and CH4 release from upland tundra
Susan M. Natali,Edward A. G. Schuur,Edward A. G. Schuur,Marguerite Mauritz,Marguerite Mauritz,John D. Schade,John D. Schade,Gerardo Celis,Gerardo Celis,Kathryn G. Crummer,Catherine Johnston,John Krapek,E. Pegoraro,E. Pegoraro,V. G. Salmon,Elizabeth E. Webb +15 more
TL;DR: In this paper, the effects of ecosystem warming, permafrost thaw, and soil moisture changes on organic carbon balance in an upland tundra ecosystem were examined at a water table drawdown experiment, established in 2011 and located within the Carbon in Permafrost Experimental Heating Research project.
Journal ArticleDOI
Greater temperature sensitivity of plant phenology at colder sites: implications for convergence across northern latitudes

Rumpf,Niels Martin Schmidt,Edward A. G. Schuur,Phillip R. Semenchuk,Tiffany G. Troxler,Jeffrey M. Welker,Christian Rixen +29 more
TL;DR: Examination of phenology data for 47 tundra plant species at 18 high-latitude sites along a climatic gradient suggests the possibility of convergence in flowering times and therefore an increase in gene flow across latitudes as the climate warms.
Journal ArticleDOI
Nitrogen availability increases in a tundra ecosystem during five years of experimental permafrost thaw.
V. G. Salmon,Patrick Soucy,Marguerite Mauritz,Gerardo Celis,Susan M. Natali,Michelle C. Mack,Michelle C. Mack,Edward A. G. Schuur,Edward A. G. Schuur +8 more
TL;DR: There is a strong positive relationship between the depth of permafrost thaw and N availability in tundra ecosystems but that this relationship can be diminished by interactions between increased thaw, warmer air temperatures, and higher levels of soil moisture.
Journal ArticleDOI
Direct observation of permafrost degradation and rapid soil carbon loss in tundra
César Plaza,César Plaza,César Plaza,E. Pegoraro,Rosvel Bracho,Gerardo Celis,Kathryn G. Crummer,Jack A. Hutchings,Jack A. Hutchings,Caitlin E. Hicks Pries,Caitlin E. Hicks Pries,Marguerite Mauritz,Susan M. Natali,Susan M. Natali,V. G. Salmon,V. G. Salmon,Christina Schädel,Elizabeth E. Webb,Edward A. G. Schuur +18 more
TL;DR: In this article, the authors quantified carbon in relation to a fixed ash content, which uses the relatively stable mineral component of soil as a metric for pool comparisons through time, and applied this approach to directly measure soil carbon pool changes over five years in experimentally warmed and ambient tundra ecosystems at a site in Alaska where permafrost is degrading due to climate change.
Journal ArticleDOI
Water-table height and microtopography control biogeochemical cycling in an Arctic coastal tundra ecosystem
David A. Lipson,Donatella Zona,Donatella Zona,Theodore K. Raab,Francis H. Bozzolo,Marguerite Mauritz,Walter C. Oechel +6 more
TL;DR: In this paper, the effects of experimental flooding, along with seasonal and spatial variation in soil chemistry and microbial activity in a DTLB, were reported. And the results indicated that the effects could have implications for C and nutrient cycling in high Arctic areas.
