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 ... -
Bioenergetic evaluation of a whole-lake nanosilver addition on Yellow Perch (Perca flavescens)
(2018)Nanosilver (nAg) is an antibacterial and antimicrobial agent. Its wide use in hundreds of commercial products and industrial applications suggests a high potential for release into the environment. Previous research indicates ... -
Characterizing the flow regime in Brook Trout (Salvelinus fontinalis) incubation habitats and the implications for management in a hydro-regulated river
(2018)Hydropower accounts for more than one third of Ontario Power Generation’s electrical production. Hydroelectric development often occurs on rivers that also support recreational fisheries. The construction and operation of ... -
The contribution of fish movement to ecosystem function in Lake Superior
(2023)Ecosystems are complex, highly interconnected systems in which organisms interact with their physical environment. Often, to simplify our understanding of their function, populations within ecosystems are treated as either ... -
Direct and indirect effects of post-fire conditions on successional pathways and ecological processes in black spruce-Kalmia forests
(2002)The goal of this thesis was to estimate the relative importance of the mechanisms by which forest stands of east-central Newfoundland are replaced by unproductive dwarf-shrub communities following wildfire. Sheep laurel ... -
Ecology and management of riparian zone vegetation along small coldwater streams in Northwestern Ontario
(2002)This thesis synthesizes three papers on the ecology of the riparian zone vegetation found along small coldwater streams in northwestern Ontario. The objectives of this thesis were 1 ) to describe the biodiversity and ... -
Edge effects at clearcut, fire and riparian buffers in the boreal forest of Northwestern Ontario
(2004)In the boreal forest of northwestern Ontario clearcutting and fire are two common edge-creating disturbances. Fundamental knowledge regarding the ability of fire and clearcut edges to minimize edge effects, preserve ... -
Effects of forest management, weather, and landscape pattern on furbearer harvests at large-scales
(2003)Over the past 50 years, Ontario’s forest landscape has changed due to ever increasing natural resource management. The natural vegetation pattern, forest composition, and the fire regime have been altered. Maintaining ... -
Effects of KNO3 and NaH2PO4 on lipid synthesis and CaCO3 accumulation in pleurochrysis carterae and newly identified algal shell coccolith structure
(2019)Due to the limited energy reserves and the increasing demand for energy, a large number of greenhouse gases such as CO2 have been released to the air. Therefore, there is an urgent need to find new sources of energy and ... -
Impacts of invasive spiny water flea (Bythotrephes cederströmii) on Walleye (Sander vitreus) mercury accumulation, ecosystem biomagnification, and bioenergetics
(2023)An evolving threat to freshwater ecosystems is invasive species. The spiny water flea (Bythotrephes) is an invasive zooplankter well known for its severe negative impacts on native freshwater zooplankton, but some knowledge ... -
Influence of overstory composition on understory vegetation and resource environment in the boreal forests of Canada
(2010)Study areas : Thunder Bay Region, Northwestern Ontario ; Northeastern Quebec. -
Invasive spiny water flea (Bythotrephes cederströmii) and their impacts on young-of-year walleye (Sander vitreus) growth
(2022)Invasive species are a major threat to aquatic ecosystems, costing an estimated $3.6 billion in impacts across Ontario. In particular, the predatory cladoceran Bythotrephes cederströmii (Bythotrephes hereafter) has had ... -
Movement, resource use, and life history strategies of Black Bay Walley (Sander vitreus)
(2019)Resource distribution across the landscape can drive movement strategy selection, from sedentary to highly mobile individuals. When paired with other forms of analysis, movement ecology can provide insight into the resource ... -
The parasite communities of two populations of walleye (Sander vitreus) from Black Bay and Circle Lake, Ontario, Canada
(2017)The parasite communities of fishes can provide important information on certain aspects of host biology such as where they have been, what they are eating, and what’s eating them. Unfortunately, fish parasite studies in ... -
Pattern and chronology of prebasic moult in wood-warblers (Parulidae)
(2003)This study compared the pattern and chronology of the prebasic moult in seven warbler species (Parulidae) at two locations in Ontario. Yellow Warblers {Dendroica petechia) were the earliest to start flight feather moult. ... -
Prediction of a modern gold mine's contaminant dispersion and deposition in a river mixing zone
(2000)Study site: Placer Dome Canada's Musselwhite Mine near Pickle Lake Ontario. -
Role of safe sites in black spruce recruitment and growth release in post-fire Kalmia heath
(2014-01-22)The goal of this thesis was to explain black spruce regeneration in postfire sheep laurel (Kalmia angustifolia L., hereafter referred to as Kalmia) dominated chronosequence in light of safe site density. The concept of ... -
Species richness, species incidence and turnover of amphibians in Northwestern Ontario : assessing the role of habitat characteristics
(2004)There has been recent global concern over the decline of some amphibian populations. The loss of amphibian species is of concern because they play a crucial role in ecosystem structure and are indicators of ecosystem ... -
Understanding drivers and correlates of fish productivity: Finding optimal indicators in freshwater fishes
(2024)Canadian freshwater commercial and recreational fisheries contribute $8.8 billion in revenue to the economy annually and are a significant subsistence food source for Indigenous communities. Fish production is recognized ... -
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 ...
