Barriers and Facilitators to Indigenous Knowledge Incorporation in Policy Making
The inclusion and application of Indigenous Knowledge (IK) has become a central and often demanded element of policy making involving Indigenous peoples. However, there are very few examples that exist in the literature and elsewhere that show how IK can be effectively integrated into decisions, policies, and programs. In response to these challenges, this research explored what processes are used to incorporate IK into policy and their effectiveness through the development of a framework that sought to identify critical factors related to IK inclusion. The framework was then applied to evaluate IK incorporation opportunities in the Nunatsiavut case, focusing on the development of the Nunatsiavut Government's Environmental Protection Act. The case study analysis was used to test and provide adaptations to the initial framework. This research identifies the importance of governance structures and processes, community participation and engagement approaches, and IK research and support programming in enhancing opportunities for IK to be integrated and reflected in policy outcomes. The Nunatsiavut case largely supported, but in some cases challenged critical factors of IK incorporation identified in the framework. The findings of this study are valuable for policy and decision makers (both Indigenous and non-Indigenous) regarding approaches and programs that can assist and support IK inclusion into policy processes and decisions.

Becoming Hybrid
Institutional military strategists are developing theories of asymmetric and unconventional warfare that complicate the notion of strategic agency, the idea that military action emanates from a coherent agential source or subjectivity. This thesis attempts to push the conceptual trajectories of the theories of Hybrid War, Unrestricted War and Onto-power towards an even more radical complication of the notion of strategy - towards an ecological understanding of war as an unwinnable, self-perpetuating process. Recent geopolitical events are meticulously examined, as are institutional doctrinal and theoretical frameworks that stop just short of imploding the conventional agential notion of strategy. Insights from the work of Gilles Deleuze and Felix Guattari, as well as Brian Massumi, particularly the concepts of multiplicity, assemblage, and ontopower, are employed in the thesis, which is itself a “heterogeneous assemblage” of elements ranging from Israeli war theory and Chinese military doctrine to etymology and post-structuralist philosophy. Author Keywords: Agency, Assemblage, Deleuze, Hybrid warfare, Multiplicity, Strategy
Becoming and Destiny in Deleuze and Guattari
This thesis is an investigation of the theme of freedom in the work of Gilles Deleuze and Felix Guattari. Chapter One investigates Deleuze and Guattari’s concept of becoming as it is articulated in their book A Thousand Plateaus, and seeks to resolve a problem related to their shifting descriptions of the role of agency in the process of becoming, at times described as voluntary, and at other times described as involuntary. We conclude that chapter with a defense of the claim that their shifting descriptions are unproblematic and are, in fact, attempts to illustrate the paradoxical experience of becoming. Chapter Two investigates Deleuze’s earlier text, The Logic of Sense, and attempts to make sense of his use of the term destiny. Our conclusion in that chapter is that destiny is neither necessity, pure self-authorship, nor passive resignation, but rather consists of a mixture of activity and passivity, willfulness and chance. Author Keywords: Agency, Becoming, Counter-actualization, Deleuze and Guattari, Destiny, Freedom
Behavioural ecology and population dynamics of freshwater turtles in a semi-urban landscape at their northern range limit
Species are faced with a variety of challenges in the environment, including natural challenges, such as variability in ambient temperature, and anthropogenic threats, such as habitat transformation associated with urbanisation. Understanding how animals respond to these kinds of challenges can advance the field of behavioural ecology and guide management decisions for wild species. Yet, we still have limited understanding of the extent of natural and human-caused impacts on animal behaviour and population dynamics, and lack robust assessment of behaviour in free-ranging animals. Using novel miniaturised biologging technologies, I characterised and validated behaviour in two freshwater turtle species: Blanding’s turtles (Emydoidea blandingii) and Painted turtles (Chrysemys picta). Further, I investigated how these two ectothermic species navigate a thermally heterogeneous landscape near their northern range limit, by comparing selected and available ambient temperatures. I showed that turtles preferred locations that were, on average, warmer and less variable in temperature than the available environment, and that this thermal sensitivity was greatest early in the year, and at fine spatial scales that likely matched the species' perception of the environment. Lastly, I assessed whether urban development was compatible with long-term viability of a Blanding’s turtle population, by monitoring habitat change and turtle survival over one decade of ongoing residential and road development. I found that Blanding’s turtle habitat quantity and connectivity declined in the area, which coincided with high road mortality and severe declines in turtle survival and population size, especially in adult females. I concluded that urban development and current road mortality rates are incompatible with the long-term viability of this at-risk turtle population. Overall, my findings demonstrate the importance of variation in the thermal environment and anthropogenic impacts on habitat in shaping the behaviour and population dynamics of this species-at-risk.

Beyond Beads
Burials at the Early Bronze Age IA (c. 3700-3400) cemetery of Fifa, Jordan included a variety of grave goods including beads. These were made of glazed steatite or carnelian. This thesis utilizes use-wear analysis, SEM-EDS, XRD, and a database of 5th and 4th millennium BCE beads in order to build life-histories for Fifa’s beads. Beyond focusing on how the beads were manufactured, where they were produced, how they travelled to the Fifa cemetery, and how they were used at the cemetery, the symbolic and contextual meanings of both types of beads are also explored. I argue that Fifa’s glazed steatite beads were manufactured in Upper Egypt while its carnelian beads were produced in Northwest Arabia. Their exchange facilitated economic and social connections. Both types of beads were likely used for their protective qualities with glazed steatite also potentially assisting in the successful reincarnation of deceased subadults.

Beyond Habitat
My objective was to understand how individual variation, in conjunction with variation in habitat, can affect individual and population-level variation in animal space use. I used coyotes (Canis latrans) as a model species to investigate the roles of hybridization, an inherited intrinsic factor, and spatial memory, a learned intrinsic factor, on space use. I used a diversity of methods and approaches, including meta-regression, multiple imputation, simulations, resource selection functions, step selection functions, net-squared displacement analysis, and survival analysis. A major contribution was my investigation of the performance of multiple imputation in a meta-regression framework in Chapter 2. My simulations indicated that multiple imputation performs well in estimating missing data within a meta-regression framework in most situations. In Chapter 3, I used published studies of coyote home range size in a meta-regression analysis with multiple imputation to examine the relative roles of hybridization and environmental variables on coyote home range size across North America. I found that hybridization with Canis species was a leading factor driving variation in coyote space use at a continental scale. In Chapter 4, I used telemetry data for 62 coyotes in Newfoundland, Canada, to investigate the influence of cognitive maps on resource use. I found that resident coyotes used spatial memory of the landscape to select or avoid resources at spatial scales beyond their immediate sensory perception relative to transient coyotes, presumably increasing their fitness. Taken together, my dissertation demonstrates that intrinsic factors, such as genetic ancestry and spatial memory, can have substantial influences on how animals use space at both individual and population levels, and at both a local and a continental scales.

Beyond Paris
A presidential spouse in an era of rigid gender norms, Jacqueline Kennedy frequently straddled the divide between celebrity, social acceptability, and personal desire. Yet, history remembers America's thirty-seventh First Lady more for her fashion and soft-spoken nature. Forgotten is that she was a `transitional' figure, who oversaw America's largest restoration of the White House and served as a `goodwill ambassador' for her husband. When three gunshots brought their tenure to an abrupt end, Jackie's focus shifted and she fixated on the creation of a legacy that immortalized JFK. `Camelot,' is a construct almost exclusively conceived and executed by the former First Lady. In this vein, the coming exploration delves into the private actions of Jackie during her time in as First Lady, contrasting them sharply with her public image. What emerges is a portrait the world seldom saw: one driven by raw intellect and a desire to be of service to her husband and country. Author Keywords: Camelot, First Lady, Jacqueline Kennedy Onassis, John Fitzgerald Kennedy, Restoration, White House
Bifacial Stone Tool Variability during the Late Paleoindian Period at Kruger 2 (BiEx-23), Eastern Townships, Québec
This thesis established the variability of Late Paleoindian bifacial stone tool assemblage from the Kruger 2 site. Kruger 2 is a basecamp occupied during the Pleistocene-Holocene transition in the Eastern Townships, Southern Quebec. The goal of this project is to quantify the variability observed in bifacial tools and to explain it. Geometrics Morphometrics and traditional attributed-base lithic analysis are used conjointly for this purpose. Geometrics Morphometrics are a set of methods that are used to distinguish groups based on their shape and to understand the differences between those groups. It is used to test the validity of the morpho-types used to classify bifacial tools found on Kruger 2 (bifaces, drills, Ste-Anne-Varney points, Agate Basin points, and other projectile points). In terms of explanation, the organization of technology postulates (sensu Nelson 1991) lies at the core of the research. The analysis involved defining the factors of biface shape variation and evaluating whether shape variation is caused primarily by raw material, function, tool life histories, or other design constraints. It was determined that all three of these factors contribute to shape differences. The data suggest that the primary factors are raw material availability and tool life histories – two factors intimately intertwined. In other words, it is the organization of technology that seems to be the driving explanatory force that accounts for shape variability.

Bio-based Polymers from Epoxidized Vegetable Oils Modified by Metathesis
The epoxides of oligomeric self-metathesized soybean oil (MSBO) and cross-metathesized palm oil (PMTAG) and canola oil (CMTAG) containing terminal double bonds were used to produce nonisocyanate polyurethanes (NIPUs) as well as anhydride, amine and thiol-cured epoxies. The synthesized NIPUs displayed metal adhesive properties for CMTAG and MSBO with MSBO being favoured probably due to its plasticizing nature as opposed to CMTAG. The relationship was reversed for the anhydride curing reaction where it was found that CMTAG, due to its lower degree of plasticizing content from the reduced dangling chains, produced higher tensile strengths than MSBO. Both MSBO and CMTAG led to fully cured amine and thiol products that were sticky gels, which prevented physical analyzses of their expected solidified products. PMTAG, due to its low number of reactive groups, was not suitable for the synthesis of these polymers.

Biodiversity patterns along a forest time series in a remediated industrial landscape
Sudbury, Ontario is an epicenter of research on industrially degraded landscapes. Regreening efforts over the past 40 years have changed the landscape, leading to an increase in forest cover in the “barrens”, that once covered more than 100,000 ha. This study characterized changes in plant and insect composition using a space for time approach in the pine plantations. A total of 25 treated sites were sampled and soil characteristics, understory plants and insect communities were assessed. All sites were contaminated with copper and nickel, but the metals had little influence on biodiversity. Vegetation diversity metrics were more strongly correlated with the pH of the organic soil horizons, while the insect community shows little response to site characteristics, and rather vegetation cover. Plant composition changes are similar to those in pine stands undergoing natural recovery and as liming effects fade there may be a decline in insect community richness.

Biogeography of Carabidae (Coleoptera) in the Boreal forest
Basic biogeographic information is lacking for many species, such as where species are found, and how they dispersed there. Using ground beetles collected during 2008-2015 from across northern Ontario and Akimiski Island, Nunavut, I present new information on ground beetle distribution in this eastern Nearctic boreal forest, including 2 first Canadian records, 9 first provincial and 48 first territorial records, as well as 74 new records that extend the known range of many large and common ground beetles several hundred kilometres. I used these distributions to redress the knowledge gap that includes fundamental distribution data, i.e. the Wallacean shortfall, and to inform later chapters in my thesis.In Chapter 3, I examine the range expansion pattern of Carabus granulatus, a non-native species, as it spread across northeastern North America and I provide a new range record. Northern Ontario is already under threat from non-native species entering the region and it is important to conduct studies in the region before more disturbance associated with development occurs. In Chapter 4, I examine the hypothesis that northern Ontario effectively acts as a climate plateau for poikilotherms, using the predictions from Bergmann's rule as my metric. The body length of ground beetles does not appear to change over the small temperature gradient that exists across northern Ontario latitudes, supporting the climate plateau hypothesis. In Chapter 5, I test hypotheses about dispersal mechanisms that contributed to post glacial re-establishment of ground beetles using predictions of geographic distribution patterns as metrics. I found that ground beetles were likely carried downstream by rivers which aided their dispersal northward from southern refugia. I infer from the current geographic distributions that flightless ground beetle species are still expanding their range in this boreal region. Finally, I argue that there is an urgent need for more basic research on species distributions while it is still possible in regions like northern Ontario, before increased industrial and agricultural development, and expanding resource extraction projects obliterate evidence of historic ecological processes.

Biology and Management of Stratiotes Aloides in the Trent River, Ontario
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 photosynthesis and turion germination to determine the light compensation point (5.2-5.4m) and maximum depth of colonization (4-6m) for S. aloides propagules using in situ incubations and controlled growth experiments. The effects of spring and fall chemical (Diquat) and physical (hand raking) treatments on S. aloides biomass, local macrophyte recovery and community dynamics in the Trent River were also measured. The target of a 75% minimum reduction in S. aloides biomass was not attained using any of the treatment methods and no perceivable recovery of the local plant community was observed. Significant S. aloides regrowth was recorded for both treatment methods regardless of application timing. Author Keywords: herbicide, invasive species, macrophyte, photosynthesis, propagule
