Temporal patterns of ungulate vehicle collisions in the Thunder Bay area
(2023)
Rising road densities, higher vehicle speed limits, and increased traffic volumes, combined with
growth in the density of various deer species, have increased the risk of wildlife-vehicle
collisions across the world. The ...
Comparison of stratification and scarification methods of Sorbus decora, Vitis riparia, and Rhus typhina
(2022)
This thesis investigates the effectiveness of three methods in breaking seed
dormancy of Sorbus decora, Vitis riparia, and Rhus typhina. The treatment methods
studied were mechanical scarification with sandpaper, ...
Indirect effects of climate change and forest fragmentation on breeding bird abundance in Ontario
(2022)
From data on forest breeding bird species in the Atlas of Breeding Birds of Ontario, this thesis summarizes population changes from 1981 to 2005 and all the direct and indirect
reasons that may lead to the decline of these ...
A spatial analysis of the relationship between forest demographic dynamics and diversity under climate change
(2023)
Forest dynamics arise from three demographic processes simultaneously, namely recruitment,
mortality and growth, all of which are expected to accelerate for the boreal forest under future
climate change. Tree species ...
Effects of nitrogen supply on the physiological and morphological responses to elevated [CO2] in yellow birch (Betula alleghaniensis Britt.)
(2023)
Ongoing climate changes can substantially impact soil nitrogen availability through its
effects on other environmental conditions such as temperature, precipitation, and the frequency
and intensity of extreme whether ...
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 ...
Exploring food system assessments as a contribution to sustainability and equity: a case study of the Thunder Bay + area food strategy community food system report card
(2023)
The corporate food regime has contributed to a number of negative outcomes that include
land, water, and ecosystem degradation; human health concerns; marginalization of smallholder
farmers and urban agriculture producers; ...
Effect of boreal forest disturbance due to logging at different spatial scales on migratory songbirds
(2024)
Boreal birds have experienced population declines that may be related to alteration of the forest
at a range of scales. Understanding how resource extraction may affect the distribution and
abundance of species is critical ...
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 ...
