It is universally accepted that human motor performance is variable in both its timing and spatial qualities. However, it is unclear to what extent motor variability impedes performance when learning a new skill and to what extent it enables our ability to learn. The first experiment examined whether performance during a test task depended on whether participants practiced to constrain or vary the task-relevant parameter. Participants used their right hand to make simple point-to-point movements. Results demonstrated the importance of paying attention to test task demands to evaluate which form of practice is most beneficial. The second experiment examined whether levels of variability could be manipulated using a reward-based paradigm to enhance learning when adapting to a perturbation of a simple visually-guided reaching movement. A reward-based feedback task was designed to encourage exploration along the task-relevant dimension, specifically movement direction variability. Overall, I did not find any significant results.

Long-term studies of demographic processes such as survival and abundance conducted in unexploited systems provide unique insight into the natural population ecology of fish, but are rarely available. I used historical tagging records of a sanctuary population of brook trout (Salvelinus fontinalis) in Algonquin Park, Ontario to investigate long-term population dynamics in an unexploited population. Adult brook trout in Mykiss Lake (23.5ha) were surveyed and tagged biannually (May and October) between 1990 and 2004. Open-population capture-mark-recapture models were used to test the importance of time, size, sex and season on estimates of apparent survival and abundance. Seasonal population growth and recruitment were estimated and compared with large-scale climate indices. Time-dependent survival and abundance estimates fluctuated, with distinct periods of increase. Population growth and recruitment were positively correlated with summer NAO and ENSO values, whereas survival was negatively correlated. Seasonally, larger individuals experienced higher apparent survival during winter and decreased survival during summer. These findings provide valuable insights into the natural demography of unexploited brook trout populations, and should help inform sustainable management of inland fisheries.

Robert Bringhurst states that polyphonic art is a faithful, artistic reflection of the multiplicity of the world's ecosystems. This ecocritical perspective recognizes that human art informs our understandings of the world, and therefore artists have a moral obligation towards that world. In Chapter One I argue that mimesis should be reclaimed as a useful literary category since all art, regardless of intentions, has an effect on both culture and the natural world. In Chapter Two I argue that by reconnecting publishing craft and philosophy, our books can serve to bring us more in tune with the structures of the natural world. I conclude in Chapter Three by asking how a counterpublic consciousness can be cultivated, and how Bringhurst's mission of transforming culture might be fully realized. Altogether, this view of literature offers an antidote to Western culture's destructive tendencies towards the natural world.

Moose are an iconic species, known for their large size and impressive antlers. Eight subspecies are classified in circumpolar regions of the planet - four in North America. Two subspecies are similar in shape and size, the north-western moose (Alces alces andersoni) and the eastern moose (Alces alces americana). It was previously believed that these two subspecies meet in northern Ontario. Earlier genetic population studies used a small number of samples from Ontario, primarily in broad studies covering all of North America.

A comprehensive genetic study of moose populations in Ontario has not previously been conducted. We examined the genetic diversity and population structure at 10 polymorphic loci using 776 samples from Ontario, as well as outgroups from representative populations – Manitoba/Cape Breton, representing A. a. andersoni, and New Brunswick/Nova Scotia, representing A. a. americana. Results indicated three genetic populations in the province, in north-western Ontario, north-eastern Ontario and south-central Ontario. RST values, compared against both FST and Jost's D values for phylogenetic analyses, indicated no phylogenetic pattern which suggests no subspeciation present in the province.

Population movement patterns in Ontario were studied. Gene flow was estimated using genetic and spatial data. Isolation by distance was only seen within the first distance class of 100 kilometres and then not seen again at further distances, indicating that moose display philopatry. There were very few migrants travelling across the province, with a greater number moving gradually north and west, towards better habitat and food sources.

A forensic database in the form of an allele frequency table was created. Three loci showed very low levels of heterozygosity across all three populations. Probability of identity was calculated for the three populations and quantified. Samples with known geographic origins were run against the database to test for sensitivity, with identification of origin occurring at an accuracy level between 87 and 100%.

Within Ontario, there are not two different subspecies, as previously believed, but two different populations of the same subspecies meeting in northern Ontario. The genetic data does not support previous research performed in Ontario. The sample sizes in our research also provide a more comprehensive view of the entire province not seen in any previous studies. The comprehensive research enabled the building of a reliable forensic database that can be used for both management and forensic purposes for the entire province.

The dissertation explores the aesthetic anthropology of Georges Bataille and his collaborators in the Collège de Sociologie, a distinguished group of intellectuals including Roger Caillois, Michel Leiris, Pierre Klossowski, and Walter Benjamin among others. At the dissertation's outset the role, influence, discovery and indeed invention of the Marquis de Sade as the almost mythic prefiguring for so much French aesthetic thought in the period beginning after World War One and up until even the present day is advanced. Before Freud in Vienna, Sade in Paris: the central thematic axis of the following addresses Eros noir, a term for reflecting on the danger and violence of sexuality that Freud theorizes with the "death drive." The deconstruction of the nude as an object and form in particular in the artwork of Hans Bellmer and the writing and art of Pierre Klossowski comprises the latter two chapters of the dissertation, which provides examples of perversion through the study of simulacra and phantasms. The thwarted pursuit of community in the vacated space of Nietzsche's death of a God is a persistent leitmotif of the following in the account it offers of the thought of Georges Bataille and other members of the Collège de Sociologie. Eros noir, at the fatal cusp between ascendant manifest sex and a latent diminished Christianity, underwrites much of the French intellectual contribution to the symbology of cultural modernism.

A bedrock fracture hosting arsenic (As) contaminated groundwater was suspected to be transported to Ramsey Lake, a drinking water resource for more than 50,000 residents of Sudbury, Ontario. A high resolution, spatial, water quality mapping technique using an underwater towed vehicle (UTV) was used to identify sources of upwelling groundwater into lake water and localize the upwelling As contaminated groundwater vent site. The top 7 cm of lake sediments (in-situ) at this vent site were observed to adsorb 93 % of the dissolved As, thus inhibiting lake water quality degradation from this contaminant source. Sediment samples from this location were used in laboratory experiments to assess the potential for this system to become a source of As contamination to Ramsey Lake water quality and elucidate As(III) fractionation, transformation and redistribution rates and processes during aging. Arsenic speciation is important because As(III) has been shown to be more toxic than As(V). To accomplish this a sequential extraction procedure (SEP) that maintains As(III) and As(V) speciation in (sub)oxic sediments and soils was validated for the operationally defined fractions: easily exchangeable, strongly sorbed, amorphous Fe oxide bound, crystalline Fe oxide bound, and the residual fraction for total As because the characteristics of the reagents required to extract the final fraction do not maintain As species.

Batch reaction experiments using sediment spiked with As(III) or As(V) and aged for up to 32 d were sequentially extracted and analysed for As(III) and As(V). Consecutive reaction models illustrate As(III) is first adsorbed to the sediment then oxidized to As(V). Fractionation analyses show As(III) most rapidly adsorbs to the easily exchangeable fraction where it is oxidized and redistributes to the strongly sorbed and amorphous Fe oxide bound fractions. Oxidation of As(III) adsorbed to the amorphous and crystalline Fe oxide bound fractions is less efficient and possibly inhibited. Select samples amended with goethite provide evidence supporting Mn(II) oxidation is catalyzed by the goethite surface, thus increasing As(III) oxidation by Mn(III/IV) complexed with the strongly sorbed fraction. Although As immobilization through groundwater sediment interactions may be inhibited by increased ion activity, particularly phosphate or lake eutrophication, this threat in Ramsey Lake is likely low.

This thesis builds on scholarship that highlights how expected gender roles serve to both normalize and obscure forms of violence and hostility in health care workplaces. An analysis of 25 labour arbitrations involving cases of bullying reveals how gender relations is a factor in these grievances and relevant policies in Ontario health care facilities. Reinforced by underlying expectations around women as nurturing and men as aggressive, responses to bullying are found to reflect and reproduce embedded gendered power inequalities in labour. While bullying in the workplace is often treated in policy discussions as an individual and identity-neutral phenomenon, this research provides evidence to the contrary. As a consequence, we must interrogate existing legislation and policies, asking how we can develop approaches that account for, respond to, and mitigate the causes of bullying rooted in unequal power relations, including gendered ones.

I have two goals. One, to offer new insights into Vienna Actionism (VA) and their notorious performances, through Gilles Deleuze and Félix Guattari's notion of the body without organs (BwO); and two, not simply to provide descriptions of the Vienna Actionists' performances, but also to write what I am calling a thesis without organs.

Documents from the Vienna Actionists, specifically Muehl's Leda and the Swan (1964), Brus' Vienna Walk (1965) and Nitsch's O.M. Theatre (1960-present), become documents without organs; they are documents that do not simply document original performances, but re-perform original performances while acting as performances themselves. Challenging the notion of live performance as fundamentally separate from its documentation (as performance theorist Peggy Phelan argues) through what Philip Auslander calls the document's performativity and what Christopher Bedford calls a viral ontology of performance, my thesis becomes a performance in and of itself. A thesis without organs.

The purpose of this study was to explore the educational implications of a clearer understanding of the practice of using multiple, including Indigenous, knowledges when finding solutions to place-based environmental issues. The impetus for my research came from a growing sense of urgency to address environmental issues within both Indigenous and non-Indigenous communities. Some have argued that communities will be most successful in understanding and resolving such issues if ways can be found to work with different knowledges. However, the practice of bringing together multiple knowledges is not yet consistently effective. At the same time, there is a recognised need for individuals who are able to use different knowledges to address urgent environmental concerns. Unfortunately, there is minimal programming advice based on the perspective of individual practitioners available to guide post-secondary institutions wishing to meet this need. This lead to my first two research questions: and

In my project, I used a relational research approach that led to a third question: How is a complexity-inspired interpretive approach suitable for exploring these questions? I had coherent conversations with sixteen practitioners who were deliberately using multiple, including Indigenous, knowledges to find solutions to place-based environmental issues. Practitioners and I co-created a Know*ledge Constellation Story to describe how they think about using knowledges in their work. In a group coherent conversation with five educators who were familiar with Indigenous-and-Environmental education, we explored the educational implications of this story. Together, we finalised a Teaching-Learning Story of Re*constellating and identified ways to prepare students to practice re*constellating, including teaching strategies and program considerations.

The Know*ledge Constellation Story and the Teaching-Learning Story of Re*constellating will inform post-secondary Indigenous-and-Environmental education. Graduates from such programs will be better prepared to engage with communities to address environmental concerns, meet legislative and policy requirements, and support research efforts that would benefit from a clearer understanding of the practice of re*constellating.

Stopover ecology is a topic that surges in relevancy as choices made by migrants during stationary periods (stopover sites) may not only have important individuals' fitness consequences but also can affect population dynamics. I used MOTUS automated telemetry array to study fall stopover duration of Blackpoll Warbler (BLPW) and departure decisions of BLPW and Canada Warbler (CAWA) in relation to various predictors. I affixed radio-transmitters on 55 BLPWs and 32 CAWAs at two banding stations in Ontario in September-October 2014-2015. Radio-tagged individuals were tracked through the MOTUS network across southeastern Canada. I developed models relating age class, fat score, Julian date and stopover movement types to Blackpolls' stopover duration. I also examined whether there were species-related differences of wind selectivity when resuming migration. No explanatory variable significantly influenced BLPW's stopover duration. Both species tended to depart under increased tailwind assistance, but with no difference in the effect of wind conditions between the two species. This study provides further evidence supporting the relevance of local wind conditions as a key factor affecting the departure likelihood, especially when migrating birds face an ecological barrier.
