Impacts of multiple extreme winter warming events on sub‐Arctic heathland: phenology, reproduction, growth, and CO2 flux responses (2011, background): “Increased freeze–thaw cycles are assumed to have large impacts on soil microbial communities of these ecosystems that affect N cycling (Grogan et al., 2004; Schimel et al., 2007; Yergeau & Kowalchuk, 2008).”
Bioavailability of terrestrial organic carbon to lake bacteria: The case of a degrading subarctic permafrost mire complex (2009, neutral): “freeze-thaw boundary and in contact with the mineral horizon have the highest DOC concentrations despite the lower total organic carbon content, likely reflecting cryoturbation processes that not only can physically breakdown the larger molecules [Bockheim, 2007] but that can also lyse microbial cel”
