In this thesis I argue that Sing-Song: A Nursery Rhyme Book (1872) disrupts conventional narratives of the idealized maternal role in the Victorian era, "the angel in the house" by confronting and giving a voice to the often overlooked realities of maternal suffering. Rossetti accomplishes this by fostering the conversation regarding the challenges inherent in motherhood. Sing-Song has been dismissed by critics as inappropriate for its intended child audience. However, such assessments rely on outdated assumptions and fail to recognize the intention behind the poetry collection. The subtle coding of the rhymes for a maternal audience has largely been overlooked. Rossetti deliberately represents the psychological and emotional complexities of motherhood, offering a more realistic portrayal of the mental health challenges that may accompany the maternal experience. In turn, Sing-Song challenges the idealized mother figure of the Victorian era and represents a more nuanced understanding of motherhood.

My research into Et'sehch'i, the Traditional Dene Burial Practices, is a comprehensive study into how smaller groups, clans, of our northern Dene understood and handled matters of funerals. The research focuses on the Dene community of Radelie Koe, Fort Good Hope in the Northwest Territories of Canada, my home community. In these Pre-Contact times, there weren't any of the modern tools we are now familiar with. The dead were interred on outdoor stages, raised platforms.

The most important part of Et'sehch'i involved the matriarch or another Elder of the clan hand-picking individual youths to help keep the Community together. They kept together as a group, going around together, cutting wood for people, hauling water or ice and generally reinstalling joy into the People's lives. Another form of these coming-of-age ceremonials involved young girls becoming women. The research involves the ways in which the Dene handled anything to do with major changes throughout our history. It was mandated by the Elders Council and Band Council of Fort Good Hope and followed a community protocol of respect for culturally sensitive material. These traditions, following ethical standards, account in good part for our survival from a time we call "When the World was New", from dinosaurs to today's computers.

This dissertation focuses on the intersectionality between images posted on social media and social rules in the lives of young people. The findings are based on thirty-four qualitative interviews with young social media users where photo-based methodologies were employed. From these interviews, three key themes emerged: 1) Posting and sharing images are connected to identity exploration and formation, 2) Social rules around embodied emotions affect how youth present their emotions in online photographic material, and 3) The conflation of private and public spaces in the digital sphere complicates how social media users interact with images. While the findings presented are clear, this dissertation aims to take a holistic approach to understanding youth digital culture and avoids coming to conclusions that view social media as "good" or "bad" for youth. This tactic allows the findings to acknowledge the complexities of communicative digital spaces and understand the intricacies of social media in the daily lives of young people (boyd, 2014; Tilleczek & Campbell, 2019). This dissertation discusses both challenges youth face on social media when posting and viewing images, as well as how images can be used to defy social norms.

Fungi are a diverse group of organisms that play crucial roles in various ecological processes and have immense economic importance. Understanding the intricate mechanisms underlying fungal growth and development is fundamental to harnessing their potential and exploring their applications in different fields. Signalling molecules, such as hormones, have been identified as key regulators in fungal physiology, orchestrating intricate processes and modulating biological responses to the environment. Phytohormones, commonly associated with plants, have been proposed as potential myco-hormones due to their production in a wide variety of fungi. Metabolomic analyses were performed via LC-MS/MS to investigate the role of phytohormones, specifically cytokinins (CKs) and indole-3-acetic acid (IAA), along with lipids and energetic metabolites such as organic acids during the growth and development of the model fungus Sordaria macrospora. The results revealed a clear switch between CK ribosides and CK free bases during the ascosporegenesis stage, with increased levels of cZ and iP and decreased levels of iPR and cZR. A similar pattern was observed in the mutant strain smgpi1 but demonstrating higher levels of CK free bases and increased fruiting body formation compared to the wild type. These findings provide insights into the regulation of phytohormones especially during fungal fruiting body development. In terms of IAA, the levels increased during the transition to sexual development in all strains, with the per5 mutant, unable to produce lipids via the cytosol, demonstrating a higher concentration than the wild type. The interplay between energetic metabolites and IAA suggests a potential role in the transition to sexual development. Additionally, the dose-dependent effects of exogenous CK application were investigated, showing the potential of low concentrations, from 1 to 10 μM, of CKs in promoting biomass accumulation or sexual development. Furthermore, gene editing in S. macrospora was proposed as a future direction to explore the functions of CKs and other metabolites during fungal development. Overall, this research contributes to our understanding of phytohormone-mediated processes in fungi and opens avenues for future investigations in fungal biology.

Mortuary archaeology presents a unique opportunity to compare cultural and biological factors within burial assemblages. This study expands upon the previous bioarchaeological research in the eastern portion of the Southern Maya Lowlands through a comparative mortuary analysis that highlights burial trends between the site of Ka'kabish, Belize, and surrounding settlements. Ka'kabish spans from the Middle Formative through to the Postclassic periods (ca. 800 BC to AD 1500) and signifies a diverse social-strata with burials ranging from a variety of ritual and domestic complexes. Ka'kabish displays a preference for primary interments of non-extended positioning, greater chultun (subterranean chambers) use than displayed regionally, potential ancestor veneration, and demonstrates a transition from public, monumental burials, to private, domestic burials, from the Middle/Late Formative to the Postclassic periods. Inter-site comparisons demonstrate that Ka'kabish's mortuary patterns do not directly fit within a specific regional trend; rather, Ka'kabish displays a wide range of influences from many sites in the surrounding lowlands.

I tracked summer movements and activity of snowshoe hares (Lepus americanus) in southwestern Yukon, Canada, during their population cycle (2015–2022) to assess the primary drivers of movement. Hares exhibited variable movement and activity during the cycle, exhibiting increased home range size and higher daily displacement during low population densities. Males exhibited more dramatic increases in their home ranges (>3-fold), and had greater and more variable movement rates and time spent travelling than females. The ratio of predators to hares was highest at low hare densities when hares were moving most, and seasonal activity of hares seemed unrelated to that of predators. Differences between sexes imply that reproductive activities likely were the main driver of hare movement variation rather than food availability. These findings reinforce that, even in highly variable environments, potential rewards associated with successful mate search and reproduction may outweigh the risks associated with reproductive behaviour.

The ᐃᓕᓕᐗᔅᑭᔾ | Ililiwaskiy (Moose Cree First Nation Territory) in Ontario's James Bay region has long faced industrial impacts on its ecosystems. Community concerns about mercury in culturally important fish prompted an interdisciplinary study bringing together chemical analysis and community knowledge. Researchers partnered with Moose Cree members through workshops, training, and interviews, while sampling over 180 fish across six sites. Walleye showed the highest mercury levels, often exceeding Health Canada's 0.5 ppm guideline for large fish and the 0.2 ppm guideline for subsistence consumers, women, and children. Community input highlighted fish as both a cultural cornerstone and food source, while noting how land-based changes have impacted fishing practices. Findings reveal elevated mercury in traditional foods and broader impacts on land-based practices and food security. The project underscores the importance of rethinking risk assessments, mitigating risks from resource extraction, water management, and supporting Moose Cree leadership in stewardship.

Hybridization contributes to the genetic diversity and can impact speciation. This study investigates the genetic evidence of recent hybridization under climate change in sympatric populations of northern and southern flying squirrels in Ontario. Using low-coverage whole-genome sequences, my research examines the existing population structure and measures the genomic variation of the Glaucomys species. The global estimates of FST (0.308) and DXY (0.141) are indicative of substantial differentiation between the species. Measures of genetic diversity (π), differentiation (FST), and divergence (DXY) across the genome reveal insights into the divergent selection driving speciation. Results indicate an absence of contemporary hybridization or introgression at a site with longstanding sympatry. Across both species' genomes, signatures of selection align with four different scenarios for the formation of genomic landscapes of differentiation, shedding light on the complex speciation history of these flying squirrels. These findings enhance understanding of evolutionary dynamics, adaptation, speciation, and genetic differentiation.

Muskrat populations are declining across North America. In recent decades, hybrid cattail Typha x glauca has been invading wetlands in North America. This invasion is degrading wetland habitat, leading to reduced interspersion of water and vegetation. Muskrats are wetland-obligates and their populations are positively linked to marsh interspersion. Therefore, muskrat populations may be declining due to the invasion of T. x glauca and subsequent reduction in interspersion. To test this hypothesis, I first sampled marshes across south-central Ontario, comparing muskrat densities with the relative frequency of T. x glauca and the degree of interspersion. Second, I measured intensity of use by muskrats in a large wetland along a gradient of interspersion. My findings suggest that reduced interspersion may be contributing to muskrat population declines, but it is unclear to what degree T. x glauca is responsible. Further research is needed to understand the effects of wetland invasions on muskrat populations.

Is trauma representation possible without re-traumatization (of self or other)? Developed through the creation, performance, and critical analysis of Titty Cakes: A Recipe for Radical Acceptance—an autobiographical, ritual-performance rooted in lived experiences of breast cancer and gang rape—this thesis argues that trauma representation is (im)possible: possible only by accepting its impossibility. To navigate this paradox, I propose the ethics and aesthetics of absence: a performance theory that resists "trauma porn" by refusing direct representation in favour of rupture, remains, and ritual. Absence is neither void nor lack; it is an ethical imperative and aesthetic strategy through which trauma is held rather than exposed, allowing the unspeakable to be witnessed. Ritual becomes the vessel for this holding: it activates affect without spectacle, invites witness without voyeurism, and fosters communitas without demanding closure. Titty Cakes stages absence as presence; where the scar, not the wound, becomes the locus of meaning.
