Abstract: <p>Trait variation in wild populations is shaped by the interaction of genetics and the environment. Given these interactions, this thesis explored trait variation in white-tailed deer from two angles: one focused on broad-scale environmental factors, the other on fine-scale genetic mechanisms. The first chapter investigated how climate and habitat variation influence antler size,… more Year: 2025, 2025

Abstract: <p>Rare earth elements (REEs) are in high demand globally for the green transition and high technologies. The growing demand leads to their release into aquatic ecosystems from various point and non-point sources, which creates urgency to investigate their fate and enrichment. This thesis further investigates the biogeochemical fate and REE uptake mechanisms throughout aquatic ecosystems.… more Year: 2025, 2025

A., Degree committee member (dgc): Summerfeldt, Laura J., Degree granting institution (dgg): Trent University Abstract: <p>Objective: The Coping Inventory for Stressful Situations (CISS) is a widely used measure of trait coping that was developed to assess three basic coping styles: task-oriented, emotion-oriented, and avoidance-oriented coping. This thesis examined the psychometric properties of a short form for the CISS (CISS-SF). Method: Data from a large longitudinal sample of adults were used to conduct… more Year: 2025, 2025

Abstract: <p>In today's digital era, smartphone use is having a profound effect on family life. There is growing concern about parental phubbing, which occurs when parents ignore their children in favour of using their phones. This study examined how parental phubbing was associated with children's problematic media use (PMU), and problem behaviours (internalizing, externalizing,attention)… more Year: 2025, 2025

From the method of the next generation matrix, a basic reproduction number is found that sets a threshold of disease persistence. It is shown that the disease disappears if $R_0<1$, which means that the disease-free equilibrium is globally asymptotically… more Year: 2025, 2025

Abstract: <p>Flavohemoglobins are enzymes primarily implicated in nitrosative stress due to their high nitric oxide (NO) dioxygenase activity and transcriptional upregulation in response to NO. Giardia intestinalis assemblages A, B, and E possess flavohemoglobins (gFlHb) that may function beyond their NO dioxygenase activity, potentially contributing to oxidative stress regulation, as transcriptional… more Year: 2025, 2025

Abstract: <p>Increasing wildfire frequency, driven by climate change, can change the concentration andcomposition of dissolved organic matter (DOM) exported from land into receiving waters by
removing terrestrial vegetation, changing soil hydrology, and interrupting microbial degradation.
In this thesis, I tested how wildfire impacts the molecular composition and reactivity of DOM. I
compared DOM… more Year: 2025, 2025

Abstract: <p>Understanding habitat needs of a species is critical, especially for species reintroduced to an area or expanding their range. I evaluated roost tree selection and survival probability of GPS-tagged eastern wild turkeys (Meleagris gallopavo silvestris) from 2017–2020 and 2022 in Peterborough County, Ontario, Canada. Fine-scale roost tree selection was associated with larger trees, with… more Year: 2025, 2025

Abstract: <p>Inserting a peripheral intravenous catheter (PIVC) can be a stressful moment in a patient's hospital stay, especially in patients with difficult intravenous access (DIVA). This study
investigated the applicability of a mid-range theory of trauma-informed care (BITTEN) to PIVC
insertion in DIVA patients. A qualitative, semi-structured interview was conducted with 17 DIVA
patients… more Year: 2025, 2025

Contextual fear conditioning (CFC) studies in rats demonstrate that distributing conditioning over multiple sessions makes a memory less vulnerable to HPC damage, and it has been suggested this occurs through incremental strengthening of the memory outside the HPC via separate… more Year: 2025, 2025

Abstract: <p>The prevalence of hypertension and mental illness among Black Canadians is a growing public health concern. There is a paucity of Canadian research exploring the lived experiences of Black individuals with both hypertension and anxiety, particularly in relation to how racism shapes access to healthcare. This study aimed to advance awareness and cultural understanding of systemic and… more Year: 2025, 2025

Abstract: <p>Risk-taking (e.g., dangerous driving, substance use) rises during adolescence and can result in both adaptive consequences (e.g., social acceptance) and maladaptive consequences (e.g., alcohol poisoning, premature death). Adolescents also experience an increase in self-conscious emotions, including shame. Shame-prone adolescents may engage in risk-taking to cope with negative self-… more Year: 2025, 2025

Abstract: <p>Many communities in Canada rely on water sourced from boreal forest headwaters for their drinking water. The Boreal Shield Ecozone is highly susceptible to climate change which threatens to exacerbate the effects of natural and human-driven disturbances such as wildfire, insect infestation and harvesting on water quality. Therefore, examining source water quality in headwater catchments… more Full Text: The effects of forest disturbance on dissolved organic carbon in the Algoma region, central Ontario A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of …
