Abstract: <p>Giardia intestinalis is the causative agent of a diarrheal disease in mammals, but the mechanisms of disease pathogenesis are unclear. While proteins secreted by Giardia affect the host cells, the potential of hormone secretion has not been investigated to date. Cytokinins (CKs) are classified as phytohormones, but little is known about their role beyond plants. Mass spectrometry-based… more Year: 2024, 2024

This paper presents two studies that explore (1) the relationship between these two models, and (2) the stability of the models and… more Year: 2024, 2024

Abstract: <p>This study aimed to explore relationships between impulsivity scores, cannabis use, and performance on vigilance, attention, and decision making tasks. We also investigated whether cannabis use related to self-reported risk taking behaviours, including risky driving, openness to engage with cryptocurrency markets, or gambling behaviour. The regular recreational cannabis users had… more Year: 2024, 2024

Abstract: <p>Population cycles are characterized by predictable temporal oscillations in population size and are influenced by densities of both predators and prey. These oscillations are influenced by the predator functional response, i.e. the influence of prey density on predator kill rate. The Canada lynx (Lynx canadensis) is a predatory mammal with cyclic northern populations driven by snowshoe… more Year: 2024, 2024

Abstract: <p>Institutional claims of university-community engagement in support of the public good and planning for teaching, learning, and research have largely remained in the realm of rhetoric. This thesis analyzes the 2019-2021 Trent University Lands and Nature Areas Plan and public consultation process, which at times was marked by the complete absence of consultation and at other times, wholly… more Year: 2024, 2024

Abstract: <p>We studied the physiological and molecular responses of lab-grown Daphnia pulex to shifts in dietary (carbon, nitrogen, phosphorus, and cyanobacteria) and growth media (calcium) nutrient supply using a set of potential biomarkers via qPCR. Each examined nutrient had a strong effect on Daphnia mass-specific growth rate, and we found significant dose-dependent effects of treatment level (… more Year: 2024, 2024

Abstract: <p>Understanding threats to declining species at multiple stages of their annual cycle is important for determining the cause of their declines and conserving their populations. To assess potential responses to changing habitat and predators under climate change, I compared the nest site characteristics, responses to human intruders, and migratory patterns between Short-billed Dowitchers… more Year: 2024, 2024

A disproportionate number of Indigenous men who are incarcerated have also been through the foster care and adoption system. A good deal of them are disconnected from their cultures, traditions and communities. For many the prisons are the first times that they encounter Indigenous Knowledge (IK),… more Year: 2024, 2024

Abstract: <p>Previous researchers have linked lower levels of stress and greater ability to mobilize energy toward a goal (self-motivation); confidence in their ability to complete/achieve a particular task or goal (self-efficacy), and ability to willfully control their thoughts, emotions and behaviour (self-control) to regular physical activity (PA). In an effort to provide further insight into the… more Year: 2024, 2024

Abstract: <p>A key knowledge gap in aeolian transport research concerns the adjustment of saltation processes to the extreme conditions found within high-latitude regions. A series of wind tunnel experiments were carried out under full climate control and over a wide range in humidity. Particle entrainment and transport within shearing flows of varied wind speed were monitored over beds of varied… more Year: 2024, 2024

Abstract: <p> Since the 1960s, post-secondary institutions (PSIs) across Chi'Mikinak (the Great Turtle) have been learning how to engage with Indigenous Knowledge Holders and their knowledges in academic programs and research, to decolonize, to support Indigenous-led initiatives, and make systemic, transformative, and reconciliatory change.

Abstract: <p>Dissolved organic matter (DOM) plays a vital role in lake ecosystems, yet its temporal and spatial variations in lakes remain poorly understood. This study investigates DOM dynamics in boreal lakes during the warm season and the Laurentian Great Lakes ice during winter. Sampling 10 boreal lakes in early and late June 2022, revealed subtle changes in DOM in the epilimnion and hypolimnion… more Year: 2024, 2024

Abstract: <p>AbstractOral Language and the Approximate Number System – A Preliminary Study
Janice Shewen
The approximate number system (ANS) involves the processing of rudimentary quantity and is
thought to be an innate developmental building block for mathematics and its sister construct, the
symbolic system. The conventional belief is that the ANS is language independent; however, this
notion is… more Year: 2024, 2024

To investigate this relationship, I conducted a
mixed-methods study. Twenty-five TCs were given a quantitative survey consisting of Likert
scales to measure their math anxiety levels and their pedagogical beliefs concerning
constructivism… more
