Iron (Fe) oxides are widely recognized to prevent the degradation of organic matter (OM) in
environments, thereby promoting the persistence of organic carbon (OC) in soils. Thus …

Wetlands are the largest and most uncertain biological source of atmospheric methane, with
hydrological fluctuations exacerbating this uncertainty. Here we critically explore the …

Permafrost thaw can stimulate microbial decomposition and induce soil carbon (C) loss,
potentially triggering a positive C-climate feedback. However, earlier observations have …

Soil organic carbon (SOC) is pivotal for both agricultural activities and climate change
mitigation, and biochar stands as a promising tool for bolstering SOC and curtailing soil …

Ice-rich Pleistocene-age permafrost is particularly vulnerable to rapid thaw, which may
quickly expose a large pool of sedimentary organic matter (OM) to microbial degradation …

Landscape-scale changes in the Arctic as a result of climate change affect the soil thermal
regime and impact the depth to permafrost in vulnerable tundra watersheds. When top-down …

Soil aggregates with spatially heterogeneous microenvironments influence microbial
communities and mineral protection in agricultural soils and play a pivotal role in soil …

Understanding the fate of organic carbon in thawed permafrost is crucial for predicting
climate feedback. While minerals and microbial necromass are known to play crucial roles in …

Thermokarst ponds (thaw lakes) are ubiquitous in northern landscapes. They are hotspots
for the biogeochemical processing of elements, such as carbon (C), nitrogen (N), sulfur (S) …

Future permafrost thaw will likely lead to substantial release of greenhouse gases due to
thawing of previously unavailable organic carbon (OC). Accurate predictions of this release …
