In the context of global warming, increasingly widespread and frequent freezing and thawing
cycles (FTCs) will have profound effects on the biogeochemical cycling of soil carbon and …

Methane emissions from organic-rich soils in the Arctic have been extensively studied due to
their potential to increase the atmospheric methane burden as permafrost thaws,–. However …

The fate of carbon sequestered in permafrost is a key concern for future global warming as
this large carbon stock is rapidly becoming a net methane source due to widespread thaw …

Permafrost-affected tundra soils are large carbon (C) and nitrogen (N) reservoirs. However,
N is largely bound in soil organic matter (SOM), and ecosystems generally have low N …

Climate change is rapidly transforming Arctic landscapes where increasing soil
temperatures speed up permafrost thaw. This exposes large carbon stocks to microbial …

Abstract Background Total DNA (intracellular, iDNA and extracellular, eDNA) from ancient
permafrost records the mixed genetic repository of the past and present microbial …

Arctic ecosystems are characterized by a wide range of soil moisture conditions and thermal
regimes and contribute differently to the net methane (CH 4) budget. Yet, it is unclear how …

In Arctic regions, thawing permafrost soils are projected to release 50 to 250 Gt of carbon by
2100. This data is mostly derived from carbon‐rich wetlands, although 71% of this carbon …

Lakes and ponds derived from thawing permafrost are strong emitters of carbon dioxide and
methane to the atmosphere, but little is known about the methane oxidation processes in …

Approximately 87% of the Arctic consists of low-organic carbon mineral soil, but knowledge
of microbial activity in low-carbon permafrost (PF) and active layer soils remains limited. This …
