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, ... -
Leaf morphological and anatomical variations of paper birch populations along environmental gradients across Canada
(2014-12-12)Leaf morphology and anatomy have been found to vary considerably among tree species, and leaf characteristics have widely been used for analyzing plant growth and resource use strategies because of their structural ... -
Limitations of forest overstory composition and age as proxies for habitat in a harvested boreal forest
(2014-12-11)Despite the importance of wildlife habitat protection in meeting land use management objectives, criteria for habitat identification are surprisingly amorphous. For example, while much current habitat modeling has tended ... -
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 ... -
Managing for Emerald Ash Borer in the urban forest
(2015)Urban forestry is a concept applied to many cities, municipalities, and communities around the world. It is the practice of managing the interface between urban infrastructure and environmental green spaces. An invasive ... -
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 ... -
Modeling uncertain demand in wood pellet supply chains: a case study from Northern Ontario
(2015-08-05)This thesis aims to enable Canadian wood pellet producers with the opportunity to offer competitive pricing through optimization of their value chains and supply chains, by employing an operational-level decision support ... -
Modelling barred owl habitat in Northwestern Ontario
(1996)With its large home range, dependence on large decadent trees for nest cavities, and association with mature mixedwoods, the Barred Owl (Strix varia) is vulnerable to habitat loss from forest harvesting. Study objectives ... -
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 ... -
Moisture reduction and nutrient retention associated with field-drying forest harvest residues on clearcut sites in Northwestern Ontario, Canada
(2012-11-10)The increased utilization of forest harvest residues as supplemental, inexpensive and renewable energy raises two key concerns: 1) continued removal may negatively affect long-term site productivity; and 2) because 50-60% ... -
Natural resource management and Indigenous food systems in Northern Ontario
(2014-12-16)The forests and freshwaters of Northern Ontario are complex socio-ecological systems that have provided opportunities to sustain local lives, economies, and cultures since time immemorial. Through nation-to-nation ... -
Nesting dynamics of the scarlet ibis (Eudocimus ruber) in Trinidad, West Indies
(2009)The effect of human disturbance on colonial waterbirds is a global issue. Many colonial waterbirds are migratory, and their protection depends on balancing conservation of their habitats and habits across many regions. ... -
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 ... -
Patterns and mechanisms of epiphytic macrolichen and abundance, diversity and composition in boreal forest
(2014-12-11)Epiphytes are important components of the forest ecosystem, but the mechanisms that control epiphyte diversity are not clear. Epiphytes are sensitive to disturbance, but their responses to stand-replacing fire are poorly ... -
Physical and mechanical property variation of black ash (Fraxinus Nigra M.) grown in the Thunder Bay seed zone
(2014-01-22)The identification of traditionally underutilized species with the potential for development and increased marketing potential has been recognized as a source of potential innovation in the Northwestern Ontario forest ... -
Physico-chemical properties of soils associated with logged forest and areas converted to teak (Tectana grandis Linn. F)
(1997)This rapid and extensive introduction of teak to satisfy a predicted wood shortage in Ghana has given rise to the question of the short/long-term effects that management of teak plantations might have on soil properties. ... -
Physiological and morphological responses of mountain maple (acer spicatum l.) seedlings to light under different carbon dioxide concentrations, soil temperature and soil moisture regimes
(2013-02-01)Determining the response of mountain maple (Acer spicatum L.) to increases in light is confounded by interaction with other environmental factors. Rising atmospheric carbon dioxide concentrations ([CO2]) and the accompanying ... -
Plant abundance, diversity, and composition following reclamation in Alberta's oil sands
(2014-12-18)The Alberta oil sands have caused an economic boom in the Canadian economy in recent years. Identifying the best strategy for vegetation recovery after oil sands extraction is critical to restoring the biodiversity and ... -
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 ... -
Predator mediated indirect effects of livestock on native prey
(2012-11-10)Livestock are common in many protected areas and due to their negative effects pose a considerable challenge to protected area managers attempting to conserve native ecosystems. Negative effects include resource competition ...
