Young and old forest in the boreal: critical stages of ecosystem dynamics and management under global change [PDF]

open access: yesForest Ecosystems, 2018
The circumboreal forest encompasses diverse landscape structures, dynamics and forest age distributions determined by their physical setting, and historical and current disturbance regimes.

COMBINING YOLO V5 AND TRANSFER LEARNING FOR SMOKE-BASED WILDFIRE DETECTION IN BOREAL FORESTS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023
Wildfires present severe threats to various aspects of ecosystems, human settlements, and the environment. Early detection plays a critical role in minimizing the destructive consequences of wildfires.

The Potential of Carbon Nanoparticles as a Stimulant to Improve the Propagation of Native Boreal Forest Species: A Mini-Review

open access: yesFrontiers in Forests and Global Change, 2022
Boreal forests across Canada and other geographic areas globally have vast networks or densities of seismic lines, pipelines, access roads, utility corridors, and multipurpose trails collectively termed “linear disturbances” or “linear features ...

Coping with Risk. A Deep-Time Perspective on Societal Responses to Ecological Uncertainty in the River Dalälven Catchment Area in Sweden

open access: yesLand, 2021
In addressing the current climate crisis, research into how past societies have coped with risk and ecological uncertainty can provide old solutions to new problems. Here, we examine how human niche construction can be seen as risk management in the face

Forest disturbance by an ecosystem engineer: beaver in boreal forest landscapes [PDF]

open access: yes, 2013
Natural disturbances are important for forest ecosystem dynamics and maintenance of biodiversity. In the boreal forest, large-scale disturbances such as wildfires and windstorms have been emphasized, while disturbance agents acting at smaller scales have

Patterns of regional site index across a North American boreal forest gradient

open access: yesEnvironmental Research Letters, 2023
Forest structure—the height, cover, vertical complexity, and spatial patterns of trees—is a key indicator of productivity variation across forested extents. During the 2017 and 2019 growing seasons, NASA’s Arctic-Boreal Vulnerability Experiment collected

Estimating seasonal variations in cloud droplet number concentration over the boreal forest from satellite observations [PDF]

open access: yes, 2011
Seasonal variations in cloud droplet number concentration (<i>N</i><sub>CD</sub>) in low-level stratiform clouds over the boreal forest are estimated from MODIS observations of cloud optical and microphysical properties, using a ...

Modeling the effects of organic nitrogen uptake by plants on the carbon cycling of boreal forest and tundra ecosystems [PDF]

open access: yesBiogeosciences, 2013
Boreal forest and tundra are the major ecosystems in the northern high latitudes in which a large amount of carbon is stored. These ecosystems are nitrogen-limited due to slow mineralization rate of the soil organic nitrogen.

The Browning of Alaska’s Boreal Forest [PDF]

open access: yesRemote Sensing, 2010
We used twelve Landsat scenes from the 1980s–2009 and regional 2000–2009 MODIS data to examine the long-term trend in the normalized difference vegetation index (NDVI) within unburned areas of the Alaskan boreal forest. Our analysis shows that there has been a declining trend in NDVI in this region, with the strongest “browning trend” occurring in ...

Natural fire regime: a guide for sustainable management of the Canadian boreal forest

open access: yesSilva Fennica, 2002
The combination of certain features of fire disturbance, notably fire frequency, size and severity, may be used to characterize the disturbance regime in any region of the boreal forest.
