Adaptability in moose (Alces alces L) : habitat selection in two landscapes in Newfoundland, Canada
(2014-01-22)Moose (Alces alces [L.]) exist circumglobally and in a vast array of different habitats. I explore differences in habitat selection in relation to differences in availability of forest stands by habitat type and number of ... -
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. ... -
Afforesting marginal agricultural lands in Southern Ontario : an investigation into the effects of planting method and vegetation management on three-year growth and development of bur oak (Quercus macrocarpa Michx.), red oak (Querus rubra L.), and, black cherry (Prunus serotina Ehrh.) plantations
(2009)Landowners in southern Ontario have become increasingly interested in afforesting marginal agricultural land. There are few appropriate, up-to-date research studies on afforestation practices to support current practice. ... -
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 ... -
Aquatic habitat use by North American moose (Alces alces) and associated richness and biomass of submersed and floating-leaved aquatic vegetation in north-central Minnesota
(2014-12-12)The North American moose (Alces alces) is a species of socio-economic importance that has undergone recent declines in some areas of its range and may be impacted by climate change through effects on physiology or habitat ... -
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 ... -
Assessment of fuel quality changes during storage of biofibre and its effect on cost
(2010)Bioenergy, energy produced from renewable biomass, can potentially replace fossil fuels and create employment in northwestern Ontario. However, the procurement of biomass for energy production can be uneconomical due to ... -
An assessment of juvenile lake sturgeon movement and habitat use in the Namakan River of Northwestern Ontario
(2013)The Namakan River of Northwestern Ontario is home to a recovering population of lake sturgeon (Acipenser fulvescens). Although the adult portion of this population has been well studied in recent years, very little information ... -
Bio based phenolic resins and adhesives derived from forestry residues wastes and lignin
(2012-11-10)The work presented here aims to produce bio-phenolic compounds from forestry biomass (residues, wastes and lignin), and substitute petroleum-based phenol with the bio-phenolic compounds to produce high quality bio-based ... -
Bottom-up and top-down forces shaping caribou forage availability on the Lake Superior coast
(2013-02-03)Woodland caribou (Rangifer tarandus) occupying the Lake Superior Coastal distribution, Ontario, exist in three subpopulations with distinct ranges and demographics. In this study, three ranges are analyzed in terms of ... -
Carbon dynamics of boreal mixedwoods in central Canada
(2009)Large amount of carbon (C) stored in boreal forest ecosystems plays an important role in the global carbon cycle. Forest ecosystem C is stored in four major pools: live vegetation (above-and below ground), dead woody ... -
Characteristics of connectivity between harvested landscapes and fixed-width riparian buffers
(2013-02-03)Fixed-width riparian buffers are a common best management policy enforced in forested landscapes on first and higher order streams. These buffer areas are delineated along stream banks in the field, based on the presence ... -
Characteristics of the boreal mixedwood forest associated with subnivean access by the American Marten (Martes americana)
(2012-11-10)Habitat selection by the American marten (Martes americana ), in studies throughout its range, has been associated with forest types that offer higher structural complexity. Such structure has been proposed to facilitate ... -
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 ... -
Charcoal in North American boreal forests: implications for carbon storage and management
(2014-01-22)Charcoal plays an important role in boreal soil function and carbon storage, and is present in most boreal forest soils as a result of naturally recurring wildfires. Charcoal management has been proposed as a potentially ... -
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 ... -
Comparative analysis of wood pellet parameters: Canadian case study
(2014-01-22)Canada is one of the world leaders in wood pellet production and export, however, domestic consumption is extremely low. In addition there is no national standard in Canada for wood pellets. The Canadian government announced ... -
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 ... -
A critical examination of chemical extremes in freshwater systems
(2015-06-15)The objectives of this thesis are to explore and identify: 1) the causative factors for extreme endpoints in freshwater chemistry, specifically eutrophication and acidification, and 2) the convergence of anthropogenic ...
