Les réservoirs de carbone en forêt boréale à l’est du Canada : acquis et incertitudes dans la modélisation face aux changements climatiques

VertigO, 2012
Climate change is of major concern for forest managers. The boreal forest is becoming increasingly central to discussions on carbon cycling because of its capacity to compensate for anthropogenic carbon emission.

Bottom-up drivers of future fire regimes in western boreal North America

Environmental Research Letters, 2022
Forest characteristics, structure, and dynamics within the North American boreal region are heavily influenced by wildfire intensity, severity, and frequency.

Interactions between carbon and nitrogen dynamics in estimating net primary productivity for potential vegetation in North America [PDF]

, 1992
We use the terrestrial ecosystem model (TEM), a process-based model, to investigate how interactions between carbon (C) and nitrogen (N) dynamics affect predictions of net primary productivity (NPP) for potential vegetation in North America. Data on pool

A pioneering pest: the winter moth (Operophtera brumata) is expanding its outbreak range into Low Arctic shrub tundra

Arctic Science, 2022
Climate warming allows generalist boreal consumers to expand into Arctic ecosystems. We present experimental and observational field data showing that a generalist boreal insect pest—the winter moth (Operophtera brumata Linnaeus, 1758)—is expanding its ...

Short‐term survival and growth of 32 native boreal plants on treated oil sands tailings

Agrosystems, Geosciences & Environment
The consolidation of oil sands tailings is a cost‐ and time‐consuming process that requires treatment via active (e.g., centrifugation) and passive (e.g., self‐weight consolidation) methods.

Contrasting foliar nitrogen nutrition of coexisting temperate and boreal trees across a modest temperature cline

Fundamental Research
The temperate-boreal forest ecotone represents a transition zone from temperate to boreal forest where nitrogen (N) is frequently limiting tree growth.

Silicified Wood‐Inspired, High‐Strength Fire‐Resistant Chitin‐Based Aerogels for Sustainable High‐Temperature Thermal Insulation

Advanced Functional Materials, EarlyView.
Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.

Northward shift of boreal tree cover confirmed by satellite record [PDF]

Biogeosciences
The boreal forest has experienced the fastest warming of any forested biome in recent decades. While vegetation–climate models predict a northward migration of boreal tree cover, the long-term studies required to test the hypothesis have been confined to

The bioclimatic extent and pattern of the cold edge of the boreal forest: the circumpolar taiga-tundra ecotone

Environmental Research Letters, 2020
Current configurations of forest structure at the cold edge of the boreal may help understand the future of ecosystem functioning in high northern latitudes.

Functional ecology of ectomycorrhizal fungi [PDF]

, 2012
Boreal forest ecosystems constitute a globally important carbon (C) sink, due to accumulation of complex organic matter, persistent to decomposition.
