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.

Traditional use of medicinal plants in the boreal forest of Canada: review and perspectives

Journal of Ethnobiology and Ethnomedicine, 2012
Background The boreal forest of Canada is home to several hundred thousands Aboriginal people who have been using medicinal plants in traditional health care systems for thousands of years. This knowledge, transmitted by oral tradition from generation to

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 ...

SAR Coherence Tomography For Boreal Forest With Aid of Laser Measurements [PDF]

, 2008
In this paper we evaluate X- and L-band SAR coherence tomography in boreal forest with the help of detailed digital terrain and canopy height models, produced by laser scanning.

The conservation of saproxylic beetles in boreal forest [PDF]

, 2006
Forest management has altered the age structure, tree species composition and dead wood availability of Swedish boreal forests. As a consequence, many saproxylic (wood living) insect species have decreased in abundance and many species are threatened ...

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.

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

Advanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...
