Abstract: <p>In 2008, the first North American water soldier (Stratiotes aloides) population was discovered in the Trent River, Ontario. Water soldier is an invasive aquatic plant with sharp, serrated leaves that has the potential to spread rapidly through dispersed vegetative fragments. Although it is too late to prevent water soldier establishment in the Trent River, its local distribution remains… more Year: 2017, 2017

Abstract: <p>The release of domestic organisms to the wild is considered a threat to </p><p>biodiversity because the introduction of domestic genes through interbreeding can </p><p>negatively impact wild conspecifics via outbreeding and local extinction. In North </p><p>America, captive American mink (Neovison vison) are frequently escaping into the wild, </p… more Year: 2017, 2017

Abstract: <p>New archaeological material was discovered in 2006 by the Göksu Archaeological Project in an area of Southeastern Turkey known as Rough Cilicia. This thesis documents and explores the material remains from funerary contexts at the sites of Dağpazarı and Topkaya. Architectural analysis of the material from Dağpazarı demonstrates that the remains are of a monumental temple tomb dating to… more Year: 2017, 2017

Abstract: <p>Many consumers purchase sweatshop products, despite the hazardous conditions for workers. The psychological factors that influence (un) ethical garment purchasing are not well understood. Two studies explored consumers' knowledge, attitudes, and behaviour. University students (Study 1; N = 130) said they would pay more for ethically-labelled garments, particularly students who were… more Year: 2017, 2017

Abstract: <p>Canada prides itself on being a multicultural nation, but the stories of people who are not "Canadian-Canadians," as defined by Eva Mackey, are underrepresented in archives. This project investigates three local archives and one online archive in Peterborough, Ontario, employing Rita Dhamoon's practice of "accounts of meaning-making" to understand how archives… more Year: 2017, 2017

Abstract: <p>From 1949-1957, Prime Minister Louis St. Laurent was the face of the Liberal Party. Party branding was wholly devoted to his friendly, 'Uncle Louis' brand image. St. Laurent's image was manipulated and manufactured without public preconception, establishing the modern tactics of personal branding still used by his successors. This thesis studies the elections of 1949, 1953… more Year: 2017, 2017

Abstract: <p>In this thesis, we study modelling with non-linear ordinary differential equations, and the existence of positive solutions for Boundary Value Problems (BVPs). These problems have wide applications in many areas. The focus is on the extensions of previous work done on non-linear second-order differential equations with boundary conditions involving first-order derivative. The… more Year: 2017, 2017

I used generalized linear mixed models to determine the factors affecting between-year variation in fall fidelity and the habitat selection in movement paths. I assessed second and third-order habitat preference by… more Year: 2017, 2017

Abstract: <p>Stressors are often an inescapable part of an organism's life. While the effects of many stressors have been well studied individually, potential interactions between stressors exist that may result in greater than additive negative effects. Stressors may be linked by conflicting demands on energy budgets, interfering with important physiological pathways, or necessitating… more Year: 2017, 2017

Abstract: <p>Tree harvesting alters nutrient cycling and removes nutrients held in biomass, and as a result nutrient availability may be reduced, particularly in naturally oligotrophic ecosystems. Selection harvesting is a silvicultural technique limited to tolerant hardwood forests where individual or small groups of trees are removed creating a "gap" in the forest canopy. In order for… more Year: 2017, 2017

Abstract: <p>Volatility modelling is an important task in the financial markets. This paper first evaluates the range-based DCC-CARR model of Chou et al. (2009) in modelling larger systems of assets, vis-à-vis the traditional return-based DCC-GARCH. Extending Colacito, Engle and Ghysels (2011), range-based volatility specifications are then employed in the first-stage of DCC-MIDAS conditional… more Year: 2017, 2017

Abstract: <p>This thesis proposes an agro-ecological zoning (AEZ) methodology of southern Ontario for the characterization and mapping of agro-ecological zones during the historical term (1981-2010), and their shifts into the long-term (2041-2070) projected climate period. Agro-ecological zones are homogenous areas with a unique combination of climate, soil, and landscape features that are important… more Year: 2017, 2017

Abstract: <p>This thesis provides an in-depth and chronological study of the development of civil aviation in the Bechuanaland Protectorate (today's Botswana), and the role played by the British Government in the development of this form of transport. The thesis argues that Her Majesty's Government's neglect and very little interest in its protectorate's civil aviation represented… more Year: 2017, 2017

Abstract: <p>As an emerging contaminant, the antimicrobial agent silver nanoparticles (AgNPs) have been receiving considerable attention to determine their potential effects to aquatic ecosystems. However, estimates of aquatic consumer survivorship and other toxicological endpoints vary considerably among experiments, largely due to the environment in which the test takes place. Throughout this… more Year: 2017, 2017

Abstract: <p>The Oak Ridges Moraine (ORM) is a key hydrogeologic feature in southern Ontario. Previous work has emphasized the importance of depression-focused recharge (DFR) for the timing and location of groundwater recharge to the ORM's aquifers. However, the significance of DFR has not been empirically demonstrated and the relative control of land cover, topography, and surficial geology on… more Year: 2017, 2017

Abstract: <p>Invasive aquatic plants can create negative ecological, economic and social impacts when they displace local vegetation, interfere with shipping and navigation and inhibit water-based recreational activities. In 2008, the first North American occurrence of the invasive plant Stratiotes aloides (Water soldier) was identified in the Trent River, Ontario. This research measured offset… more Year: 2017, 2017

Abstract: <p>The global food system has been criticized for being environmentally, economically and socially unsustainable. As part of a local food movement, farmers' markets (FM) are undergoing a revival in response to the escalating food system globalization of the past century. Despite the prevalence of FMs as formalized organizations, there remains a significant range in their operational… more Year: 2017, 2017

Nevertheless, the parasite encodes several hemeproteins, including three members of the Type II cytochrome b5 sub-group of electron transport proteins found in anaerobic protist and amitochondriate organisms.… more
