Abstract: <p>Arctic breeding shorebirds are often considered alternate or secondary prey to avian and terrestrial predators that primarily feed on cyclic populations of rodents. Predation risk can strongly influence habitat selection; however, there is limited understanding of how nest placement by shorebirds and subsequent risk of nest predation are affected by spatiotemporal patterns involving the… more Year: 2024, 2024

Abstract: <p>Sexual agency is receiving more attention in sexuality research though its contribution to sexual well-being has yet to be determined. Sexual agency has been theorized as an overarching concept comprised of both internal and external components. Both feelings and behaviours in the sexual domain can be impacted by prevalent culturally prescribed sexual scripts. The present study assessed… more Year: 2024, 2024

The WWTP exported 354.1 ± 24.7 billion microplastic particles, or 296.7 ± 39.4 kg of microplastics; of this, 85.7% of counts and 86.6% of mass was exported via biosolids. As such, microplastic loads in biosolids need to be reduced before… more Year: 2024, 2024

Abstract: <p>Animal migration is defined as the seasonal movement from one independent and non-overlapping range to another. Understanding how and why animals migrate is important not only to understand their life history processes but also for informing other important ecological processes such as the spread of wildlife disease and habitat alteration. Animal migrations have been impacted by human… more Year: 2024, 2024

Abstract: <p>The neuronal ceroid lipofuscinoses (NCLs), commonly known as Batten disease, are a family of fatal neurodegenerative disorders that primarily affect children. Several subtypes of NCLs have been reported, each being caused by a mutation in a distinct ceroid lipofuscinosis neuronal (CLN) gene; this results in aberrant lysosome function and the accumulation of lipoprotein aggregates (known… more Year: 2024, 2024

However, how these changes have affected the diets and isotopic niches of predatory fish is largely unexplored. My diet study analysed stomach contents from five… more Year: 2024, 2024

Abstract: <p>Despite the extensive application of Baumrind's parenting style typology, some argue that it may not adequately capture the implicit warmth Chinese parents embrace. This study attempted to examine whether mind-mindedness could be a key indicator for helping children understand the benevolent intentions behind their mothers' authoritarian parenting practices. Specifically, this… more Year: 2024, 2024

Structure D-6, together with Structure D-7, comprise the site's only known ballcourt. Performance theory is used in tandem with the existing literature about the Mesoamerican ballcourt's crucial function within the legitimization strategies… more Year: 2024, 2024

Abstract: <p>Darwinian fitness is determined by the outcome of allocations of energy and nutrients to plant growth, survival, and reproduction. Allocations to reproduction differ from allocations to growth and survival because the products of reproduction (pollen, ovules, and fruits) are dispersed away from the plant and so the resources used to produce them cannot be re-allocated. As a result, and… more Year: 2024, 2024

Abstract: <p>Understanding tissue turnover rate is crucial for isotopic analysis. Collagen, a main component of bone, is often studied in archaeology and paleontology, yet bone collagen turnover rates across various skeletal elements, remain underexplored. This study addresses this by assessing collagen turnover rates in multiple human skeletal elements using the bomb carbon dating method. Seven… more Year: 2024, 2024

Abstract: <p>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… more Year: 2024, 2024

Abstract: <p>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… more Year: 2024, 2024

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… more Year: 2024, 2024

Abstract: <p>Agricultural and urban land uses have been linked to the recent resurgence of eutrophication and salinization issues in the lower Great Lakes. This thesis examined the relationship between watershed land use and stream nitrate-nitrogen (NO3-N), total phosphorus (TP), and chloride (Cl) concentrations across southern Ontario. Using a self-organizing map analysis, the watersheds were… more Year: 2024, 2024

Abstract: <p>Due to climate change and managed care, birds may face interacting effects of novel diets and environmental temperatures. I examined how captive zebra finches (Taeniopygia guttata) responded to a 6-month acclimation to either thermoneutral or cool temperatures when provided with saturated or unsaturated fatty acid enriched diets. Body mass was lower on the unsaturated fatty acid diet,… more Year: 2024, 2024

Abstract: <p>There is a `universal' picture of a charged domain wall (CDW) in theoretical work, often depicted as residing in an infinite thickness film, charge neutral, and with no bias voltage applied. However, in experiment CDWs are shown with none of these assumptions. CDWs are produced in thin or ultra-thin films, the CDW is not charge neutral, and a bias voltage is being applied. We look… more
