Assessment of black spruce portfolio trial survival and growth and implications for reforestation under climate change
(2018)The purpose of this study is to assess the performance of black spruce seedlings at a genetic trial designed to select seed sources adapted to several climate change scenarios. Height variability among trees is attributed ... -
An assessment of the utility of an unmanned aerial vehicle for measuring tree heights in a jack pine provenance trial
(2020)This independent study is an assessment of the utility of an unmanned aerial vehicle (UAV) for measuring the heights of jack pine (Pinus banksiana) trees in a provenance trial. An electronic hypsometer, the Haglöf Vertex ... -
Comparison of deer browsing intensity of tree seedlings in open and fenced plots in Southern Ontario, Canada
(2024)This study examined the intensity of browsing by white-tailed deer (Odocoileus virginianus) on tree seedling growth in wildlife management unit (WMU) 83B. The study was conducted in an island ecosystem that has regular ... -
Ecotypic variation of black spruce in northwestern Ontario
(2020)The success of reforestation can be improved by selecting the appropriate seed source for the site type. However, not much is known about the differences in using upland versus lowland black spruce seed sources when ... -
The effects of stratification methods on paper birch and yellow birch seed germination
(2022)This study examines the use of both a typical cold moist stratification method, and an alternative in their ability to affect germination rates in paper birch (Betula papyrifera) and yellow birch (Betula alleghaniensis). ... -
A framework for assessing skills training programs for building Indigenous capacity in natural resource development
(2019)Indigenous participation in natural resource development has become an integral part of the advancement of major projects both in Ontario and across Canada. This participation until the most recent decades was limited by ... -
The genetic diversity of eastern North American tree species as related to the extent of their spatial distribution during the Last Glacial Maximum
(2020)The distribution of boreal and temperate species during the last glacial maximum (LGM) in Eastern North America can have a significant effect on the genetic diversity of present day populations. Here, I modelled the LGM ... -
Genetic variation of functional traits related to drought tolerance in yellow birch seedlings
(2022)Understanding patterns of variation in drought-related traits of hardwood trees is crucial for conserving and managing North American temperate forests under climate change. In this study, I examined provenance variation ... -
Habitat composition and spatial response of white-tailed deer to forestry treatments in moose range, Grand Portage Indian Reservation, Minnesota
(2020)Moose (Alces alces L.) have long been an important subsistence species are of great cultural value to the Ojibwe peoples. White-tailed deer (Odocoileus virginianus Z.) have been implicated in negatively impacting ecosystems ... -
Interfamily variation in wood quality of black spruce in a northwestern Ontario progeny trial
(2020)The right trees for replanting must be selected to ensure optimal future forest conditions. Based on desired future outcomes, various progenies can be selected to suit these needs. In Canada, black spruce (Picea mariana), ... -
Intraspecific height variation of white spruce provenances in Ontario
(2020)Provenance tests in Ontario have been used for decades to evaluate the optimal seed sources for different environments. Understanding the genetics, adaptations and selection pressures of tree species using provenance ... -
Investigation of adaptive variation of black spruce in 29-year height growth of Black Spruce in a northwestern Ontario provenance trial
(2023)Seed sources from across northwestern Ontario were used to establish a black spruce provenance trial at the former Thunder Bay Forest Nursery located on 25th Sideroad, Thunder Bay. The heights of these trees were measured ... -
Jack pine fitness under current and future climate
(2020)Climate change has the potential to drastically alter the functioning of Canada’s forests and the species that live there. The importance of understanding patterns of adaptive variation in relation to climate is imperative ... -
Landscape genetic analysis of population structure and barriers to gene flow in boreal woodland caribou (Rangifer tarandus caribou)
(2023)This study examines patterns of population genetic structure and gene flow of boreal woodland caribou (Rangifer tarandus caribou), which are experiencing declining population sizes across North America. Compared to ... -
Lichen detectability under varying canopy closure
(2019)Monitoring lichen distribution is of increasing concern as mapping is critical in characterizing habitat for woodland caribou. Aerial photography collected using drones, the method used for this study, is a common method ... -
Literature review of aquatic invasive species management in the Great Lakes region
(2019)Invasive species are foreign organisms which out-compete and take over new landscapes and are ranked as one of the most destructive forms of habitat degradation (McCormick et al. 2009). Aquatic invasive species specifically ... -
Optimal black spruce seed sources for anticipated future climates
(2020)Climate change is occurring at an increasingly rapid pace. Many tree species, even those with wide seed dispersal and high genetic variability, are long-lived and unable to “keep pace” with these shifting climates. The ... -
Patterns of mercury accumulation in northern Ontario walleye and relationship with watershed characteristics
(2018)Mercury is a well known toxic contaminate that poses health risks to humans and wildlife. In Ontario 85% of consumption restrictions of fish from inland lakes is due to mercury contamination. The purpose of this study was ... -
Population genetics of caribou in the Brightsand range of Ontario
(2022)Boreal woodland caribou are listed as threatened in Ontario. This thesis examined whether the genetic diversity of boreal woodland caribou in the Brightsand Range differs comparing populations in portions of the range with ... -
Relationship between glacial refugial range and genetic diversity in eastern North American conifer species
(2020)The aim of this thesis is to relate genetic diversity to the extent of glacial refugia in several important North American conifer species. Refugial locations were hindcasted using MaxEnt software with occurrence points ...
