A comparison of the effectiveness of ground versus aerial chemical site preparation
(2020)Silviculture operations in northwestern Ontario can include the use of chemical site preparation to remove competing herbaceous vegetation to promote the establishment of conifer seedlings. Aerial and ground applications ... -
Comparative analysis of soil properties influenced by wildfire and sustainable forest licence harvesting practices
(2019)This thesis outlines the main differences and similarities between current forest harvesting practices and wildfire disturbances in the boreal forest. Boreal harvesting is carried out in a way that looks very similar to ... -
Variation of fungal endophyte diversity between healthy branches of balsam fir and branches infected with fir broom rust
(2020)A total of 241 isolation attempts were made, with 233 yielding cultures from 61 branches collected from two balsam fir trees. The most commonly found fungal endophyte in healthy branches of balsam fir was Foveostroma ... -
An inquiry into the fungal diversity associated with the galls formed by Pemphigus betae Doane
(2020)Leaves affected by galls induced by the aphid Pemphigus betae were collected from a Populus balsamifera tree located near the community garden on the campus of Lakehead University Thunder Bay. Out of the galls that were ... -
Analyzing impacts of brush saw and herbicide treatments on branching and stem quality in northern Ontario jack pine plantations
(2020)In an industry where new science is ever-evolving, forest managers must constantly look towards research to guide best practices in achieving the highest quality forest product. Three common silvicultural treatments ... -
A comparison microplastics effects on atlantic cod (Gadus morhua) and blue mussels (Mytilus edulis)
(2020)This thesis explores the potential impacts that can occur in Atlantic cod and blue mussels resulting from the ingestion of microplastic particles based on a review of previously published studies. This thesis summarizes ... -
The effects of plantation spacing on Pinus resinosa wood density variation and managing for increased carbon sequestration
(2020)Pinus resinosa is found throughout a large portion of eastern North America. Dating back to the early settlement era, wood utilization has varied from solely infrastructure to bioenergy and carbon sequestration. Although ... -
Strategies to reduce the decline of wild bumble bees in North America: are they working?
(2020)Bumble bees are major pollinators of the world’s agricultural crops and wild plants and, as such, play a key role in maintaining economic prosperity and biodiversity. The decline of wild bumble bees in North America has ... -
Control measures of gypsy moth and the effect of STS modeling in Canada
(2020)Gypsy moths are an introduced invasive species which causes decline in oak and maple in southern Ontario. In 1869 the moth was introduced into Massachusetts by Leopold Trouvelot, whose mission was to start a silk industry ... -
Potential factors that influence the silvicultural status of a stand based on its silvicultural background
(2020)The silvicultural effectiveness monitoring program is important in determining the silvicultural status of a stand. Each stand can be classified as being a silvicultural success (SS), regeneration success (RS), or not ... -
The impact of invasive thistle species on dynamics of Cercopidae in the Stikine-Skeena region of northern British Columbia
(2020)During the Summer of 2019 I worked on suppressing invasive species spread in the Stikine-Skeena region of Northern British Columbia. I frequently observed invasive thistle species of the genus Cirsium hosting abundant ... -
Living in the plastic crisis: a study of student awareness & behaviour regarding single-Use plastics on Lakehead University Campus
(2020)Human induced plastic pollution is causing undeniable devastation among Earth’s natural resources. As research concerning the crisis begins to progress, it is important that its data includes human awareness and behaviours ... -
The effect of Bacillus thuringiensis serotype kurstaki (Btk) as an insecticide on jack pine budworm in the 2019 Northern Ontario spray program in comparison to historical use
(2020)Bacillus thuringiensis (Bt) has been used historically as an insecticide by the Ontario Ministry of Natural Resources and Forestry (OMNRF) to suppress jack pine budworm populations in dense outbreaks. In some previous ... -
