Global carbon dioxide efflux from rivers enhanced by high nocturnal emissions
Carbon dioxide (CO2) emissions to the atmosphere from running waters are estimated to be four times greater than the total carbon (C) flux to the oceans. However, these fluxes remain poorly constrained because of...

Open AccessNorth American boreal forests are a large carbon source due to wildfires from 1986 to 2016
Wildfires are a major disturbance to forest carbon (C) balance through both immediate combustion emissions and post-fire ecosystem dynamics. Here we used a process-based biogeochemistry model, the Terrestrial ...

Open AccessForest fires in Canadian permafrost region: the combined effects of fire and permafrost dynamics on soil organic matter quality
Wildfires burn approximately 1% of boreal forest yearly, being one of the most significant factors affecting soil organic matter (SOM) pools. Boreal forests are largely situated in the permafrost zone, which c...

Open AccessThe impact of wildfire on microbial C:N:P stoichiometry and the fungal-to-bacterial ratio in permafrost soil
Wildfires thaw near-surface permafrost soils in the boreal forest, making previously frozen organic matter available to microbes. The short-term microbial stoichiometric dynamics following a wildfire are criti...
