Wildfires mediate carbon transfer from land to lakes across boreal and temperate regions Mathilde Bélair Ian M. McCullough Jean-François Lapierre Communications Earth & Environment(2025) Increasing severity of large-scale fires prolongs recovery time of forests globally since 2001 ...
Canadian forests cover a vast area of nearly 362 million ha (ref.9), amounting to 8.5% of the global forested area10. These forests are an important sink of carbon, absorbing fossil carbon dioxide (CO2) from the atmosphere and slowing the pace of climate warming11,12. However, climate...
This includes the impacts of paleo-wildfires on surrounding marine basins by affecting sedimentation rates and nutrient input via soil degeneration and intensification of continental run-off. The Late Cretaceous was an important time of global climate shift, with the rise of angiosperm vegetation ...
(warming water temperatures, longer open water seasons, extreme hydrological events, intensifying wildfires). Canadian rivers are especially important to the overall biogeochemistry, hydrology, biodiversity, and ultimate health of aquatic and terrestrial ecosystems. While each of Canada’s provinces and ...
"Given the unpredictable behavior of wildfires and the number of significant wildfires in all areas of the province, we're bringing in the additional resources we need to keep people and communities as safe as possible," said Doug Donaldson, Minister of Forests, Lands, Natural Resource Operations...
Disturbances in northern forests are interconnected and often reinforce each other. As wildfires become more frequent, they accelerate permafrost thaw, and in turn, thawing permafrost contributes to conditions that promote further fire95. Drier soils and the increased likelihood of peat burning create a...
(2126 years old), and <F"Times">the four others originated from wildfires (80 years old). Nonlinear ageheight analyses were used to compare annual height and radial increment growth of black spruce (Picea mariana(Mill.) BSP), jack pine (Pinus banksianaLamb.), and trembling aspen ...
To achieve these objectives, we sampled six large wildfires one year after they burned in the Northwest Territories and northern Alberta, Canada, characterizing soil, vegetation, and fire properties, and sequencing microbial (bacterial/archaeal and fungal) communities using the ribosomal RNA gene. The...
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 contains half of global soil carbon (C). Wildfires advance thawing of...
Forest fires are responsible for 14~20% of the annual global burned area (Mouillot and Field2005; van der Werf et al.2006), which is between 50~90 Mha (Schultz et al.2008). In Canada, an average of about 8000 forest fires occurs each year burning 2 Mha of forests, most of which ...
