, 2013 Half of the world's forest is in boreal and sub-boreal ecozones, containing large carbon stores and fluxes. Carbon lost from headwater streams in these forests is underestimated.

Land, 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

Estimating seasonal variations in cloud droplet number concentration over the boreal forest from satellite observations [PDF]
, 2011 Seasonal variations in cloud droplet number concentration (NCD) in low-level stratiform clouds over the boreal forest are estimated from MODIS observations of cloud optical and microphysical properties, using a sub-adiabatic cloud model to interpret ...

Comparison of boreal ecosystem model sensitivity to variability in climate and forest site parameters [PDF]
, 2001 Ecosystem models are useful tools for evaluating environmental controls on carbon and water cycles under past or future conditions. In this paper we compare annual carbon and water fluxes from nine boreal spruce forest ecosystem models in a series of ...

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

Overwintering fires in boreal forests [PDF]
Nature, 2021 Forest fires are usually viewed within the context of a single fire season, in which weather conditions and fuel supply can combine to create conditions favourable for fire ignition-usually by lightning or human activity-and spread1-3. But some fires exhibit 'overwintering' behaviour, in which they smoulder through the non-fire season and flare up in ...

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

Boreal forest fire emissions in fresh Canadian smoke plumes: C_1-C_(10) volatile organic compounds (VOCs), CO_2, CO, NO_2, NO, HCN and CH_3CN [PDF]
, 2011 Boreal regions comprise about 17% of the global land area, and they both affect and are influenced by climate change. To better understand boreal forest fire emissions and plume evolution, 947 whole air samples were collected aboard the NASA DC-8 ...

Fire, 2023 Soil organic carbon (SOC) is an important component of the ecosystem carbon pool, and fire is one of the important disturbances in forest ecosystems. With global warming, there has been a gradual increase in boreal forest fires, which has a nonnegligible

A phytosociological survey of the boreal forest (Vaccinio-Piceetea) in North America [PDF]
, 1998 A survey of syntaxa of vegetation of North American boreal forests (class Vaccinio-Piceetea) is presented. This phytosociological survey, carried out combining the Braun-Blanquet method with numerical syntaxonomical analyses (cluster and correspondence
