Ostrich Eggshell from the Far Eastern Steppe
This study uses stable isotope analysis on both the organic and inorganic fractions of ostrich eggshell obtained from archaeological excavations in Mongolia, northern China, and southern Siberia. By establishing the δ13Corg, δ15N, δ13Cinorg, δ18O isotopic compositions of the eggshell of the Asian ostrich (Struthio asiaticus), this study provides insight into the maximum northern range of the species, which I suggest reached Lake Baikal, Siberia through the late Pleistocene, up to the Last Glacial Maximum. Through these isotopic data, the interactions between S. asiaticus and human forager groups are explored, specifically the trade of ostrich eggshell by hunter/gatherer populations in the early/middle Holocene. Because of deviations from the correlation between δ18O and latitude observed for other sites, the site of Shabarakh-usu may have been an aggregation point for ostrich eggshell from other locations. Movement of eggshell is observable from north to south but not from south to north on the basis of eggshell δ18O. Finally, I am able to develop a hypothesis regarding the drivers of species extinction. Specifically, I discuss trade in eggshell leading up to extinction as evidence for human pressure on S. asiaticus at a time when environmental shifts likely isolated populations in small regions of habitable landscape. I therefore implicate both changing environmental conditions and human pressure in my proposed explanation for the extinction of S. asiaticus.

Managing Through Change
Arctic ecosystems are increasingly altered by climate change, and some wildlife species, like moose, are adapting to these new conditions. Indigenous knowledge and values, such as those held by Inuit, can provide insight into adaptive wildlife management and may improve ecosystem resiliency. This thesis seeks to address the following question: What is the potential role of Indigenous knowledge in managing wildlife under climate change? This thesis follows a qualitative exploratory design involving 1) a systematic literature review of the peer-reviewed literature and 2) a case study on moose in Nunatsiavut in which 35 interviews and participatory mapping were conducted with Inuit beneficiaries. The results demonstrate a range of potential roles for Indigenous knowledge and values in managing species impacted by climate change. The case study of moose in Nunatsiavut has applicability across the Canadian Arctic where the sustainability of harvested species is at risk. Author Keywords: Arctic, climate change, Indigenous knowledge, moose, Nunatsiavut, wildlife management
Surface temperature regulation during stress exposure
The influence of stress exposure on the body temperature of vertebrates has been known for nearly two-thousand years. While the proximate mechanisms supporting this phenomenon are well described, the ultimate mechanisms remain enigmatic. In this thesis, I propose a novel hypothesis which states that changes in body surface temperature (henceforth "surface temperature") following stress exposure occur to reduce energetic expenditure toward thermoregulation, thus freeing energy for use in the stress response (hereafter, the "Thermoprotective Hypothesis"). Using a paired experimental design, I first show that black-capped chickadees (Poecile atricapillus, Linnaeus, 1766) exposed to repeated stressors decrease their surface temperatures at low ambient temperatures, and increase their surface temperatures at high ambient temperatures relative to unstressed controls. These changes in surface temperature contribute to a relative reduction in heat loss in the cold, and a relative increase in heat dissipation in the warmth among stress-exposed individuals, thus reducing their energetic demands toward more costly thermoregulatory strategies. Next, I show that stress-induced changes in surface temperature are most pronounced in chickadees that experience naturally-occurring resource-restrictions, suggesting that this response occurs to balance allocation of energy among the stress response and thermoregulation (i.e. a true energetic trade-off ). Third, I show that the magnitudes of chronic, stress-induced changes in surface temperature are highly variable among, and highly consistent within, chickadees, therefore suggesting that this response could hold adaptive significance if such variation among individuals is heritable. Finally, using domestic pigeons (Columba livia domestica, Gmelin, 1789) as a model species, I show that stress-induced changes in surface temperature are highly pronounced at bare tissues with a critical role in thermoregulation for some avian species (the bill), when compared with responses at surrounding bare tissues (the eye region). Together, these findings strongly support the Thermoprotective Hypothesis and suggest that endotherms may trade energetic investment toward thermoregulation with that toward the stress response in resource-limiting environments.

An Exploration of Partnership Models for Urban Conservation Land Management in Ontario
Partnerships for management of public parks have a long history, but little attention has been given to the current models of partnerships during a period of municipal austerity in Ontario. Using a qualitative assessment of transcripts from representatives of 10 municipal partner groups, this research considers what some of the current models are, the impact that they may have, and how municipalities may foster these partnership arrangements. The participating organizations demonstrated that their governance models evolved to suit their mandate, activities, and scope of interaction with their municipality. Additionally, this research corroborates past findings that efficacy of an organization is tied to their ability to partner with other agencies and act as a capacity amplifier. These results demonstrate how municipal conservation partnerships can be effectively applied to create enhanced financial outcomes and improved community engagement, while delivering community based environmental programming.

Morphology, Production and Trade
The Africana IIA, an amphora subtype of the Africana II class, was produced in Africa Proconsularis (the present-day Tunisian Sahel) during the mid-Roman Imperial period (from the late 2nd c. A.D. to the middle decades of the 3rd c. A.D.), and was distributed around the western Mediterranean. Scholars have noted meaningful morphological variations on this subtype’s rim but had overlooked the information that these rims may convey. The preliminary analysis of the variations found on Africana IIA amphora rims yielded possible connections to various production sites or regions, distribution samples, and/or consumption sites, and suggested that at least some of the rim variants were indicative of origin. The rim variants also seemed to correlate to different trade routes, and potentially, different trade mechanisms, including private versus State interests.

Examining Strategies of New Public Management in Homelessness Policy
This research is a critical analysis of coordinated access as an approach to addressing homelessness focusing on Peterborough, Ontario as a case study. This study is situated in scholarship that explores the presence of strategies of New Public Management in social service and healthcare delivery. Balancing the methods of Smith’s (2005) Institutional Ethnography and Bacchi’s (2009) What is the Problem Represented to Be approach I investigate the way that Federal, Provincial and Municipal homelessness policies organize themselves as instruments of power and I connect this analysis to the accounts of staff working within the homelessness response system. I discover the frame of vulnerability through which homelessness is addressed to be an individualizing mechanism that facilitates the downloading of responsibility for social welfare to local governments without adequate resources. I argue that the consequence of an under resourced system is that only the most extreme forms of suffering can be addressed, and the tools used to decipher who is most vulnerable do not account for structural inequalities.

Nassau Mills Complex
The objective of this thesis is to develop and implement a heritage plan for the Nassau Mills Complex, a locally-significant Euro-Canadian historical site that operated on what is now Trent University’s campus in Peterborough, Ontario. Within the framework of public archaeology and Cultural Heritage Management (CHM), emphasis is placed on the importance of protecting the site and its historic remains in order for present and future generations to appreciate and enjoy. Data was gathered by way of field and archival research, as well as through consultations with various archaeological and museological professionals. Of particular concern is evaluating how the Complex is significant to Peterborough, how it should be commemorated, public engagement and the importance of information accessibility, and the potential issues that may arise as a result of this project. In addition, recommendations regarding how the site and its collections should be preserved and presented to the collective society are also examined.

Changes in the Representations of Women from the 1980s Turkish Cinema to New Turkish Cinema
The thesis examines the changes in the representations of women in Turkish cinema from the 1980s through the 2000s in terms of semiotic codes. To demonstrate the shifts of the representations of women over three decades, four films directed by two representative filmmakers of the 1980s and the 2000s are analyzed within the context of gender codes: A Sip of Love (Atıf Yılmaz/1984), The Night, Angel and Our Gang (Atıf Yılmaz/1994), The Third Page (Zeki Demirkubuz/1999) and Envy (Zeki Demirkubuz/2009). Using gender as code in deconstructing women’s characteristics and their representations in the films, the research highlights the structural image of women in the semiotic sense. The stereotypical representations in Turkish cinema question social norms, patriarchy, and Islamic norms in Turkey. Author Keywords: Gender codes, Islam, Patriarchy, Semiotics, The representations of women , Turkish cinema
Creation During Abandonment
This thesis addresses the excavation and analysis of the Hingston Group, a small courtyard group just south of the ceremonial core of the Ancient Maya city of Ka’kabish in North-Central Belize. I use settlement and household archaeological theory to understand the functions, occupation history, and status of this residential group. I also rely on entanglement theory, along with the hypothesizes presented by Palka (2003) and McAnany (1995), to create a possible interpretation for the reasons why we see what we do in the Hingston Group during its main period of occupation. The Hingston Group is composed of three structures and two chultuns (underground storage areas). Research teams excavated both chultuns during prior field seasons and found burials from the Postclassic and Late Formative Periods. This information led to the assumption that the occupation of these structures would correspond to one, or both, of these periods. However, we found that this courtyard group was occupied during a period when the rest of the core of Ka’kabish was abandoned. Along with this, excavators found an ephemeral occupation into the Colonial Period; these two new periods of occupation have expanded our understanding of the chronological history of Ka’kabish.

Prioritizing Restoration Potential within Protected Areas in Haliburton County, Ontario
Ecological restoration helps managers of protected areas respond to challenges presented by factors that threaten ecological integrity and respond to residual effects of previous land use. Many protected areas require restoration on sections of the property, due to previous land use. The objective of this thesis is to present criteria that assist ecological restoration professionals in assessing the potential of restoration projects within a protected area, based on the restoration wheels from the International Principles and Standards for the Practice of Ecological Restoration. The criteria were discovered from a review of the literature and reinforced from interviews with experienced restoration practitioners and a focus group session with key members of the Haliburton Highlands Land Trust (HHLT). Based on the combination of biophysical and socioeconomic values in the restoration wheels, they are presented in the form of a five-star assessment system to create long-term restoration goals for properties of the HHLT and protected areas in general. These long-term restoration goals can be utilized in conjunction with the wheels and five-star assessment tools to prioritize restoration projects Author Keywords: Determining Project Potential, Ecological Restoration, Evaluating Success, Haliburton, Land trusts, Restoration Wheels
Civic Agriculture
This thesis re-imagines the social sustainability of civic agriculture. This entails critically examining the idea of sustainability and exposing why a tendency to undertheorize its social dimension is problematic for how we think about sustainability, and consequently for how we do sustainability. What is demonstrated is that we can overcome this tendency by adopting Stephen McKenzie's understanding of social sustainability as a positive condition and/or process within a community. Once brought into contact with the concept of civic agriculture as presented by Thomas A. Lyson, and expanded upon by others, this broadened understanding of social sustainability reveals that we can think of civic agriculture as both a means to, and an expression of, social sustainability. Specifically, this thesis argues that it is civic agriculture's community problem-solving dimension which animates civic agriculture in such a way that it creates the sort of condition and/or enables the sort of process which reflect aspects associated with a substantive and/or procedural understanding of social sustainability. This re-imagining of the social sustainability of civic agriculture provides ways to defend civic agriculture from its critics and is exemplified by drawing from a personal encounter with civic agriculture. In the end, it is proposed that in light of this research there are now good reasons to re-examine civic agriculture and to critically re-imagine what qualifies who as a civic agriculturalist so that the contextual nature of the social sustainability of civic agriculture can be better respected. Author Keywords: civic agriculture, community problem solving, local food systems, social sustainability, Stephen McKenzie, Thomas A. Lyson
Signalling Beliefs in Ogilby's AFRICA
This study analyzes Christian European perceptions of group identity and beliefs in early modern geographic literature, as exemplified by John Ogilby’s Africa (1670), a selective translation of Olfert Dapper’s 1668 work, and its descriptions of West-Central Africa. Ogilby’s work, congruently with contemporary geographic literature, employed the Christian religion as a key marker of group identity, using it as a lens to interpret and define the collective identities of African societies it described. Using a theoretical framework derived from Daniel Bar-Tal’s Group Beliefs, the thesis demonstrates that Africa portrayed the officially Christian kingdom of Kongo as superior to its non-Christian neighbours, consistently represented in a negative light. This attitude reflected normative European beliefs of Christian superiority fanned by the period’s intense denominationalism and religious anxiety. Africa’s general ecumenism towards other Christian denominations and its maintained “othering” of non-Christian Africans was closely linked to Ogilby’s own sense of self-identity and group beliefs shaped by his life experiences in the seventeenth-century British Isles. Author Keywords: Africa, Christianity, Identity, Kongo, Ogilby, Syncretism
