The antifeedant action of climacodon septentrionalis and two species of sphaerobolus to hyphal grazing by the fungus-feeding nematode aphelenchoides sp.
(2012-11-10)Fungi are ubiquitous in forest ecosystems and are, collectively, a major force in driving nutrient and organic matter availability and cycling. Some saprotrophic and mycorrhizal fungi are characterized by a perennial ... -
Characterization of rooting patterns in mixedwood forests of white spruce and trembling aspen: Is competition reduced belowground?
(2012-11-10)This study examined the rooting patterns of white spruce (Sw, Picea glauca (Moench) Voss) and trembling aspen (Pt, Populus tremuloides Michx.), and the effect of stand type upon such patterns. Specifically, contrasts were ... -
Ecophysiological responses of white birch seedlings to soil temperature and phosphorus supply under current and doubled carbon dioxide concentration
(2009)To investigate the responses of some physiological and morphological traits to different soil temperature and phosphorus supply under current and doubled carbon dioxide concentration ([CO2]), white birch (Betula papyrifera ... -
From coal to wood thermoelectric energy production: Socio-economic impacts in northwestern Ontario, Canada
(2016)The province of Ontario in Canada is the first North American jurisdiction with legislation in place to eliminate coal-fired thermoelectric production. Ontario Power Generation’s (OPG) coal-fired Atikokan Generating Station ... -
Global environmental change effects on forest dynamics: lessons from permanent sample plot networks
(2019)Global environmental change caused by anthropogenic emissions of greenhouse gasses is a major threat to forest ecosystems globally. Before we can begin to adequately mitigate these threats, we first must understand how ... -
Identification of boreal mixedwood forest structure cohorts in Northwestern Ontario using Ontario's forest resource inventory, Abitibi-Bowater's continuous forest inventory and stepwise discriminant function analysis
(2009)A model was developed to determine if Ontario's Forest Resource Inventory (FRI) could be used to classify boreal mixedwood stands in northwestern Ontario into structural cohorts as proposed in the Multi Cohort Forest ... -
Influence of regeneration method on juvenile jack pine clear wood static bending properties and specific gravity / by Karen L. Jackson.
(2008)The effects of regeneration method on three wood properties of jack pine, along different vertical positions, grown in northwestern Ontario were evaluated. A multi-staged nested sampling design was used to randomly select ... -
Integrating a tactical harvest-scheduling model with a log sort-yard location model
(2014-01-22)Failure to sort logs prior to their transportation to a mill can result in a loss of value in the forest products supply chain—for unsorted, higher value logs can be used in a low-value product where lower valued logs ... -
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 ... -
Investigating productivity and foliar nutrient status in second growth white spruce (Picea glauca) and trembling aspen (Populus tremuloides)
(2012-11-10)This thesis synthesizes two related papers investigating competitive interactions of second growth white spruce (Picea glauca [Moench] Voss) and trembling aspen (Populus tremuloides Michx.) at the Fallingsnow Ecosystem ... -
Linking environment, biodiversity, and ecosystem functions in forest ecosystems
(2014-12-16)The positive biodiversity and ecosystem functions relationship (BEF) has been well established, especially in controlled experiments. However, a coherent study to examine the multiple relationships in BEF in natural ... -
Modeling the woody biomass supply chain for energy production in northwestern Ontario
(2014-01-22)Efficient procurement and optimal utilization of woody biomass for bioenergy production requires a good understanding of biomass supply-chain management. The general objective of this research is to develop decision support ... -
Modelling the radial and longitudinal variation in wood density and its sensitivity to climate in black spruce (Picea mariana (Mill.) B.S.P.)
(2014-01-22)Wood density variation affects structural timber performance and is correlated with different sources (genetic diversity, stand dynamics and climatic effects) which, to date, have not been comprehensively quantified in ... -
Patterns and mechanisms of tree species diversity effects on fine root processes associated with stand development in boreal forests
(2018)Over the last two decades, one major advance in ecology has been the demonstration that biodiversity has positive effects on a broad range of ecosystem functions. However, diversity-ecosystem functioning studies for ... -
Understory species response to partial harvesting in boreal riparian buffers
(2009)In order to preserve valuable riparian functioning, forest harvesting in Canada attempts to protect riparian areas through the application of a no-harvest buffer zone around water bodies, and more recently through the ... -
Using Remote Sensing for Quantity Analysis of Chip Pile Inventory in Mill Yards
(2016)An integral part of proper wood chip inventory management is the ability to accurately monitor wood chip quantities. This thesis examines the use of a new method of capturing the volume of mill yard wood chip piles through ... -
Woody biomass-based bioenergy development at the Atikokan power generating station: local perceptions and public opinions
(2015-08-05)To tackle climate change, reduce air pollution and promote development of renewable energy, the Ontario government is investing in the conversion of the coal-based Atikokan Power Generating Station (APGS) in Atikokan, ...
