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 ...
Investigation of capacitor voltage balancing issues in a five-level inverter with multicarrier modulation schemes
(2023)
Five-level inverters are widely used in medium-voltage (MV) wind energy and
electric drive systems. However, the use of a large number of components (including passive
and active components) and complex control methods ...
Evaluating the effects of biomass harvesting on soil nutrient availability, foliar nutrition, and seedling growth in third-growth black spruce plantations in northwestern Ontario
(2023)
Residual forest biomass is a viable feedstock that can be used in the
bioenergy stream. There remains, however, a concern that excessive removal of
forest biomass may have negative impacts on forest biodiversity, ...
Evaluating the effects of clearcutting, wildfire, and bioenergy wood ash application on forest soils to improve emulation silviculture
(2023)
Ontario’s forest management guides promote the use emulation silviculture to manage
the province’s forests on a landscape scale based on natural disturbance regimes. While clearcut
harvesting can have similar effects to ...
The potential uses of virus-infected symbionts to improve drought and heat stress in trees for improvement, climate change resilience, and restoration
(2023)
With the rapid changes occurring to the climate of the boreal forest, many
populations of trees are facing increased stresses and seeing lower productivity and
survival. Conventional tree improvement programs take decades ...
The effect of ectomycorrhizal fungus Hebeloma longicaudum on drought stress of Pinus banksiana seedlings
(2023)
This study looks at the influence of the ectomycorrhizal fungus Hebeloma longicaudum
to form associations and impact growth of jack pine seedlings under simulated drought
conditions. Four treatment groups of jack pine ...
Driver and landscape-related factors associated with reported wildlife-vehicle collisions in Thunder Bay, Ontario
(2022)
The ever-expanding road network in Ontario has created serious implications for wildlife
and their movement within the province. This has led to the discovery of many factors that have
the potential to increase the risk ...
Tracking stand-level responses (mortality and recovery) in jack pine (Pinus banksiana Lamb.)- dominated stands following the recent jack pine budworm (Choristoneura pinus pinus F.) infestation across northwestern Ontario
(2023)
This study investigates the stand-level responses (mortality and recovery) in jack pine-dominated forests
following a recent infestation of the jack pine budworm across northwestern Ontario. The aim is to
understand the ...
Challenges with regenerating chipper debris pads: evaluating seedling performance nine years after planting
(2023)
Debris from in-bush portable chain flail chippers can alter the abiotic
environment factors within the mineral soil. Thus, chipper debris can create an
unsuitable seedbed for seedling growth and survival. In this thesis, ...
Wildlife management on urban golf courses: the case of the Ottawa Hunt and Golf Club
(2023)
Urban development has put increasing pressure on public greenspaces and the local
wildlife populations encompassing them. Golf courses are an accessible way for the public to
view the natural environment and wildlife ...
