Dissolved Organic Carbon Mobilization and Degradation Patterns in Retrogressive Thaw Slumps of the Peel Plateau, Northwest Territories, CanadaDownload
Anthropogenic climate change has affected the Canadian Arctic cryosphere, accelerating the development of retrogressive thaw slumps (RTS) across the Peel Plateau, NWT, Canada. RTS result from the thawing of ice-rich permafrost and develop due to ablation of ground ice exposed in the slump...
Microbial community dynamics from permafrost across the Pleistocene-Holocene boundary and response to abrupt climate changeDownload
Permafrost houses active microbial communities adapted to constant sub-zero temperatures and anaerobic conditions. These extreme conditions make permafrost an excellent archive for long-term DNA preservation. Recent studies in the laboratory have shown a shift in permafrost bacterial communities...
Polar warming will lead to increased labile organic carbon in Arctic soils, both from the release of organic carbon stored in permafrost and increased plant production. The impact of increasing organic carbon on Arctic soil microbial community composition and activity is of great interest...
