Patterns and mechanisms of understorey vegetation associated with stand development in boreal forests
(2018)
The understorey vegetation comprises the greatest plant diversity and contributes
substantially to ecosystem functioning and services in boreal forests. Although many studies
have examined patterns of understorey species ...
Trade-offs between economic gains and ecological functions following forest management alternatives in boreal forests
(2018)
Intensive forest management activities that maximize economic gains could negatively impact the long-term sustainability of ecological functions and associated ecosystem services. Understanding the trade-offs between ...
Past and future impacts of climate change on boreal forest timber supply
(2018)
The boreal forest is home to a thriving forest industry which requires stable, long term timber to remain viable. Anthropogenic climate change, caused by the release of greenhouse gasses, is occurring rapidly in northern ...
Effects of nutrient supply, soil temperature and root interactions on morphology, growth, biomass and physiological responses of black spruce and white spruce seedlings to CO2 elevation
(2012-11-10)
Changes in atmospheric CO2 concentration ([CO2]) and temperature may influence nutrient resources and how boreal species respond to their environment. The effects of increased [CO2] on plants are generally positive but can ...
Climate change-associated temporal increase of tree mortality and its consequences in central and western Canadian boreal forests
(2014-01-22)
Tree mortality influences forest structure, composition and ecosystem functions. To assess how recent climate changes affected tree mortality, observational studies conducted in old-growth forests have shown that tree ...
Foliar nutrient resorption and litterfall production with stand age, overstory composition, and disturbance origin in boreal forests
(2015-01-13)
Nutrient resorption (NuR) prior to developmental senescence allows for nutrient conservation in plants, driven primarily by genetics, development stage, climate and soil fertility, and litterfall is the vector for the ...
Impacts of invasive earthworms on carbon storage in southern boreal hardwood forests
(2017)
The introduction of invasive, non-native earthworms into forest ecosystems has increased as recreational, industrial, and commercial activities increase in northern Ontario. The presence of these ecosystem engineers in ...
The estimation of boreal forest properties using spectral indices
(2018)
The field of forestry has evolved to meet several objectives, including timber and other forest product production, tourism and recreation, habitat and wildlife management and climate change monitoring. As the field ...
Effect of harvest intensity on soil carbon and nutrients across global forests: a meta-analysis
(2018)
Logging residues can retain important nutrients for tree growth after biomass harvesting. However, increasing the harvest intensity may decrease soil nutrient stores stocks and affect biomass productivity. Using 2207 ...
Effects of mechanical site preparation on the growth of Jack Pine (Pinus banksiana)
(2018)
The boreal forest in Canada provides a large volume of timber for Canadians and other countries year after year and effective silviculture is the key to sustainable harvesting. Site preparation can be a critical step in ...
