disconnect between indigenous traditional connection with water due to water insecurity
(2023)people indigenous to what is now northern ontario have always had a traditional connection and relationship with water. in recent year, that relationship has been put through many obstacles amounting to water insecurity. ... -
the effects of a forest fires on water flow and quality in lakes surrounding a northern ontario mine
(2023)water quality and quantity can be greatly impacted following a forest fire, but fire impacts can vary based on fire intensity, watershed topography, and post-fire precipitation events. forest fires are an important ... -
opportunities for indigenous fire stewardship within ontario’s policy framework
(2023)indigenous people have used fire as a tool for thousands of years for resource management, community protection, and cultural purposes. the criminalization of the practice during colonization in combination with a history ... -
valorization of kraft lignin via alkaline and acid- mediated aerobic oxidation processes
(2023)lignin is a complex heterogeneous aromatic compound derived from renewable plant biomass. due to its aromatic backbone, it has grown interested in producing biochemicals and other polymeric applications. depending on the ... -
the phase behaviour of isopropanol/water/nacl mixtures at atmospheric pressure
(2023)alcohol-based biofuels will play a key role in substituting the fossil fuels used in transportation and power generation. compared to fossil fuels, alcohol-based biofuels have a lower carbon footprint and can be produced ... -
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 ... -
medical text simplification: bridging the gap between medical research and public understanding
(2023)text simplification is a subdomain of natural language processing that focuses on applying computational techniques to modify the content and structure of the text to make it interpretable while retaining the main idea. ... -
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 ... -
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 ... -
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, ... -
effects of the nitrogen deposition on the forest ecosystems: an overview
(2023)human activities exacerbate the production and emission of reactive nitrogen and lead to the increase and globalization of nitrogen deposition. at present, the interference of human activities in the global nitrogen cycle ... -
trends in breeding propensity of common loons (gavia immer) in relation to lake water clarity in and around algonquin provincial park
(2023)productivity of common loons has been in decline across most of canada for several decades. many environmental factors and human impacts on the breeding grounds may be causing the decline, and these factors are known to ... -
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, ... -
a review of silvics, stand dynamics, density management, and vegetation management in the ontario boreal forest
(2023)adaptive forest management requires constant re-evaluation of the efficacy and impact of current practices. continuous development of information is key to any adaptive management regime, especially in the face of ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
an exploration of image recognition in archaeological starch analysis
