Assessment and evaluation of soil health indicators with changes from boreal forest to agriculture in Thunder Bay, Ontario
(2022)The boreal forest is one of the most extensive biomes in Canada at an estimated 2.7 million ha. The requirement for a growing agricultural sector, along with a currently warming climate, has accelerated the conversion ... -
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 ... -
Assessment of hazard tree/snag detection using drone-based, multi-spectral sensors
(2022)Snags are an integral component of forest ecosystems as they provide habitat for a number of different species and add complexity to vertical forest structure. However, snags also may pose as potential hazards to people ... -
Assessment of lake trout (Salvelinus namaycush) mercury concentration across a gradient of food web complexity and environmental variables
(2023)Exposure to mercury has been linked to health risks in both people and wildlife. In Ontario, mercury pollution is to blame for 85% of the consumption restrictions on fish from inland lakes. Heavy metals like mercury ... -
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 ... -
Assessment using TerrSet geovisualisation of the temporal and spatial effectiveness of the prescribed burn program in re-establishing the oak savannah habitat at the Pinery Provincial Park
(2022)Oak savannah is a plant community of widely spaced deciduous trees with a canopy cover of between 25 to 35%, allowing grasses and other ground cover vegetation to thrive, providing habitats for numerous plant and animal ... -
The association of rat prevalence and composting in Thunder Bay’s urban neighbourhoods
(2023)Landfilling is the most common municipal solid and urban organic waste disposal method in North America and comes with numerous negative environmental side effects. Encouraging greater participation in community composting ... -
Autonomous surface vehicle for mechanized bathymetric surveys
(2022)This study evaluates the efficacy of an Autonomous Surface Vehicle (ASV) constructed from inexpensive consumer off the shelf components for suitability in surface-based bathymetry of large-scale tailing impounds found ... -
Barriers which preclude the formation of strong, comprehensive wildfire mitigation plans and strategies in Ontario: a knowledge gap analysis
(2023)As occurrences of wildland-urban interface (WUI) wildfires become more frequent throughout Ontario, there has been an increasing need for mitigative approaches towards managing wildfire on landscapes, especially where ... -
Behavioural analysis of meadow jumping mice; Zapus Hudsonius
(2020)Temperament studies of animals can provide unique insight on how behaviour, genetics and environmental factors interact to influence the evolution and dynamics of populations. This, in turn, can be used to predict how ... -
The behavioural effects of anthropogenic noise on Rainbow Trout in a holding facility
(2018)There is a growing concern within the scientific community about the effects of anthropogenic noise on fish. Pile driving creates large amounts of noise, and especially in the creation of bridges it has the ability to ... -
The benefits of implementing tire pressure control systems (TPCS) in northwestern Ontario
(2022)Transporting raw forest products to processing facilities is one of the highest costs of overall timber production. Many forestry contractors and log truck owners are looking for feasible ways to minimize forest road ... -
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 ... -
Biodiversity of ground beetles in young and old poplar stands
(2019)Ground beetles (Coleoptera: Carabidae) are a useful bioindicator group in forests in almost every part of the world. This thesis studied the biodiversity of carabid beetles in old and young age trembling aspen (Populus ... -
