A review of forestry’s impacts on methylmercury in aquatic ecosystems and recommendations for best management practices in Ontario’s boreal forest
(2023)Mercury contamination in freshwater fish of Northern Ontario is exceeding levels safe for consumption and is negatively impacting remote communities. This literature review examines the impacts of specific forest operations ... -
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 ... -
A review of the biological significance of coarse woody debris in forest ecosystems and its positive impact on forest characteristics
(2020)Coarse Woody Debris (CWD) is considered any woody decay that has fallen on the forest floor. This important piece of forest ecology has a large influence on a variety of forest characteristics. This thesis first evaluates ... -
Review the function of large aquatic plants in water pollution treatment
(2018)Being a worldwide problem, water pollution has a huge impact on the mankind. The world has invested a lot of manpower and material resources after the environmental governance. Environmental pollution control has a new ... -
Revision of the nearctic species of the Cicindela sylvatica group (Coleoptera: Cicindelidae)
(1983)Interspecific and intraspecific variation of C. longilabris Say and C. nebraskana Casey were studied by means of discriminant analysis of morphometric data and univariate analysis of qualitative characters of adult ... -
Rewording elder abuse : a test of six frameworks
(2001)The term “elder abuse” carries powerful connotations and preconceptions, making the topic a difficult one to broach. In order to effectively reach older adults, their family members and caregivers, educators would do ... -
RF coils design for small animal MRI lung imaging at 3T using hyperpolarized 129Xe and inert fluorinated gases
(2014-01-22)This thesis described the investigation, construction and testing of two sets of RF coils for their applications in novel lung MRI imaging techniques. In the first part of the thesis, a quadrature-driven birdcage coil for ... -
Riparian habitat and vegetation recovery of headwater streams after clearcut harvesting
(2009)In this thesis I examined two important aspects of clearcut harvesting along small headwater streams and their riparian zones. The objectives of the study were: 1) to investigate the impacts of clearcut harvesting on the ... -
Riparian vegetation patterns and links with surface waters in the boreal forest
(2007)Riparian areas in the Canadian boreal forest represent the transition zone between terrestrial and aquatic ecosystems. Factors that influence riparian vegetation communities and the associated interactions with boreal ... -
Riparian vegetation response to clearcutting along small streams of boreal forest / by Shekhar R. Biswas.
(2008)In this thesis I examined three important ecological questions to understand the role of forest management disturbance on unmapped small stream riparian plant communities: I) how do small stream riparian plant communities ... -
Rise of the machine: the making of the video game industry and military simulation
(2014-01-22)Rise of the Machine assesses the history and development of the home video game industry and its technological evolution from a military industrial structure that has its roots in the Second World War. The thesis focuses ... -
Rise up!? : an analysis of appreciative resistance in environmental education / by Blair Niblett.
(2008)This thesis explores the relationship between the concepts of education and activism. I suggest that educators can approach activism in ways that are consistent with the aims of education. In support of this suggestion, I ... -
Risk sensitive foraging by rats in the operant arena
(1988)The operant arena was used as the framework in which to study the theory of risk-sensitivity, A small colony of hooded rats was exposed to increasing work demands while given the choice between simultaneous fixed ratio ... -
Risk-sensitivity in a rat population under interval schedules of reinforcement : open and closed economies
(1995)A group consisting of eight male Hooded rats was tested for risk-sensitive foraging preferences in an eight station operant arena, under conditions of open and closed economies. The group could choose to forage at either ... -
Risky riding: a comparison between two personality theories on motorcyclist riding behaviour
(2018)Motorcyclists have the highest likelihood of being involved in a fatal crash of all vehicle passengers. Given the multiple human factors that contribute to crash involvement, few personality models have been utilized to ... -
Road-network location heuristics for the tactical harvest-scheduling model
(2022)In tactical planning in hierarchical forest management, cut-blocks are selected for maximizing revenue and road networks are allocated at minimal cost in order to maximize profit. The selected cut-block set and requisite ... -
