Adaptive variation of trembling aspen in Northwestern Ontario
(2015-08-05)
To demonstrate the pattern of adaptive variation of Populus tremuloides (Michx.)
to northwestern Ontario climate conditions, a statistical analysis was completed of
growth and phenology variables from 26 provenances. ...
Key factors influencing First Nation youth perspectives on forest management and capacity development in northern Ontario, Canada
(2018)
First Nation youth often play a central, though indirect, role in Ontario’s forest sector as the beneficiaries of capacity-building arrangements, employment opportunities and cultural-retention initiatives. Correspondingly, ...
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 ...
Inventorying cutover logging residues: A remote sensing approach
(2012-11-10)
The purpose of this study was to quantify the volume of logging residues within forest harvest blocks, using an airborne, remote sensing based method. The objective was to measure the volume using a field technique, and ...
Ecophysiological responses of black spruce (Picea mariana) seedlings to nutrient supply, N-P-K ratio and photoperiod at current and elevated CO2 concentration
(2012-11-10)
The relationship between plant growth and nitrogen supply is frequently used in growth models to predict growth performance under global climate change scenarios. However, the relationship may be changed under elevated ...
Pre-harvest lumber value recovery modeling: integrating sawline laser-scanning with an enhanced forest inventory
(2012-11-10)
Supply chain management research in forestry is becoming increasingly important in the forest sector worldwide. Predicting lumber value recovery from pre-harvest forest inventory forms an important aspect of forestry supply ...
A Comparison of beaver foraging behaviour in two national parks
(2012-11-10)
Strategies adopted by foraging herbivores are influenced by the availability of resources. Beavers (Castor canadensis) are important ecosystem engineers, having the ability to modify the landscape through the consumption ...
Growth and photosynthetic responses of white spruce seedlings to levels of trembling aspen and red raspberry cover
(2012-11-10)
The effect of competitve species upon crop tree regeneration and growth continues to receive attention from researchers due to the importance of the outcomes. This study stakes a new approach, by examining the combined ...
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 ...
Assessing above- and belowground competitive effects in pure and mixed stands of jack pine (Pinus banksiana) and black spruce (Picea mariana)
(2009)
Ecological principles of niche, competition and competitive reduction suggest that competition in mixed stands composed of pine and spruce may experience positive interactions through (1) vertical stratification of canopy ...
