Fish and fishing practices in the upper severn river watershed: listening to stories and exploring changes over time
(2024)The effects of environmental change and proposed mining in remote northern Ontario has created an immediate need for the Keewaytinook Okimakanak Tribal Council (KOTC) member communities of the Upper Severn River watershed ... -
Effects of different intensities of thinning on ground beetles (Coleoptera : Carabidae) in a black spruce plantation
(2024)Thinning is a silvicultural practice implemented to maximize harvest productivity. However, biodiversity conservation is a growing trend, therefore it is important to understand the short, and long-term effects of thinning ... -
Cost-benefit analysis of scarification in the boreal forest
(2024)Soil scarification is a site preparation method that improves growing conditions for seedlings. The practice has associated benefits and costs putting its feasibility into question within the boreal forest. The costs ... -
Exploring supports for students’ complex climate emotions through interviews with Ontario Secondary Teachers
(2024)Young people are most vulnerable to the impacts of climate change and grapple with a range of challenging emotions regarding climate change. Climate change education aims to increase knowledge and engagement in climate ... -
Older age and poor health outcomes within Black communities: an assessment of risk during the COVID-19 pandemic
(2024)To assess the impact of the COVID-19 pandemic on older adults within Black communities in Canada, the study described self-reported health ratings before and during the pandemic, across age groups and assessed how old ... -
Biodiversity loss due to the increase of monoculture lawns
(2024)Lawns have evolved over time, starting as functional spaces in medieval gardens to appearing as the manicured, European-inspired landscapes we know today. The widespread use of monoculture lawns in North America signifies ... -
A review of the Toronto Zoo's head-starting program for recovery of the Blanding's turtle in Rouge Valley National Urban Park
(2024)Conservation reintroduction programs are valuable tools in supporting endangered or extinct species in the wild. With the many ways humans are causing adverse environmental impacts, it is crucial that we put effort into ... -
Energy density of fish within an aquaculture experiment
(2024)Understanding how small-bodied fish are affected by aquaculture is important to help complete the picture on how aquaculture affects all levels of the ecosystem. I analysed the energy density for small-bodied fish in the ... -
Economic risk analysis of the Bronze Birch Borer on the Thunder Bay campus of Lakehead University
(2024)Urban forests serve many purposes to a city, from parks to street trees to crown cover in downtown cores. Trees in urban environments are more prone to stress and pathogen due to the environment in which they live. Birch ... -
Health and management of trees planted in tree pits in Thunder Bay’s downtown north core
(2024)A survey of Thunder Bay’s downtown north core (formerly known as Port Arthur) examined 276 trees in an attempt to correlate the size and health condition of the trees with the size of the planting site. The largest and ... -
Variations of saproxylic beetle assemblages within the same white spruce logs across early and advanced decay classes
(2024)Saproxylic species play a multitude of essential ecological roles within the forest ecosystem by undergoing a distinct succession as deadwood decays in the early to late successional stages. As of 2024, knowledge regarding ... -
Evaluating feller buncher performance in interior British Columbia
(2024)This thesis examines the performance of harvesting equipment in British Columbia's forestry sector. The study examines two forest stands under CANFOR Ltd. in Prince George, British Columbia. It uses data from modern ... -
Assessing remote sensing estimations for burn area and tree mortality
(2024)Remote sensing tools will increase the ability of land managers to visually sample large areas more feasibly. This increase in applications of remote sensing such as UAV aerial LiDAR may require an assessment of ... -
The effects of lake acidification on small-bodied fish populations
(2024)Industrialization has had adverse effects on the environment. Through mining and burning of fossil fuels, acidic precursors are emitted into the atmosphere creating acid rain. Acid rain is then deposited into freshwater ... -
Comparisons of ground-dwelling beetle assemblages in different stand types at Jack Haggerty Forest
(2024)Beetles (Coleoptera) play an important role in Canada’s boreal forest as they aid in many forest processes. Ground-dwelling beetles are the focus of this study, and most of these beetles belong to the families Carabidae, ... -
Evaluating the application of LiDAR to measure wildland fire depth of burn In the Canadian boreal forest.
(2024)This study evaluates the accuracy of Light Detection and Ranging (LiDAR) technology in measuring the depth of burn (DoB) resulting from wildland fires in the Canadian boreal forest. An analysis of the correlation between ... -
Ore mineralogy of Mattabi Mine, Northwestern Ontario, Canada
(1990)The Mattabi Mine, a volcanogenic massive sulfide deposit located 60 km north of Ignace Ontario, in the Archean Superior province, produced 13.5 mt of ore with an average grade 7.5% Zn, 0.88% Cu, 0.77% Pb and 3.10 oz/t Ag ... -
Petrographic and fluid inclusion studies on the Metalore-Golden highway deposit, Thunder Bay District, Ontario
(1993)The gold-bearing Metalore shear zone and Golden Highway quartz-carbonate vein in the Beardmore-Geraldton Archean Greenstone Belt occur along the Paint Lake splay faults at the contact between metavolcanic rocks and ... -
Comparative analysis of remote sensing and ground-based surveys in determining merchantable volume of a boreal forest stand
(2024)Accurate volume estimations are pivotal for effective forest resource management, influencing stakeholders throughout the forestry industry. Traditionally, estimations relied on stem diameter measurements and geometric ...
