    Direct and indirect effects of nest predation risk on Arctic breeding shorebirds: Does availability of alternative prey contribute to nest mortality?

    Year: 2024, 2024
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Huang, Richard Kin Keung, Thesis advisor (ths): Nol, Erica, Thesis advisor (ths): Brown, Glen, Degree granting institution (dgg): Trent University
    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

    The Interrelationships Between Sexual Agency, Sexual Consent Communication, Sexual Motivations, and Positive Sexual Evaluations

    Year: 2024, 2024
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Hébert, Kalyca-Lyn L., Thesis advisor (ths): Humphreys, Terry, Degree committee member (dgc): Navara, Geoff, Degree committee member (dgc): Milhausen, Robin, Degree granting institution (dgg): Trent University
    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

    Microplastics in Wastewater: Annual Trends and Biosolid Treatment Strategies.

    Abstract: <p>This thesis determined the temporal dynamics of microplastics in the biosolid and final effluent of a WWTP for one year (October 2020–September 2021). 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
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Sucharzewski, Stephen, Thesis advisor (ths): Northrup, Joseph M, Thesis advisor (ths): Patterson, Brent R, Degree committee member (dgc): Shafer, Aaron B, Degree granting institution (dgg): Trent University
    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

    Name(s): Creator (cre): Thanabalasingam, Aruban, Thesis advisor (ths): Huber, Robert J, Degree committee member (dgc): Yee, Janet, Degree committee member (dgc): Donaldson, Micheal, Degree granting institution (dgg): Trent University
    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

    Abstract: <p>Lake Huron's food web has experienced drastic changes in response to multiple stressors including declines in offshore productivity, decreased trophic transfer efficiency and a transformation of the benthic food web. 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

    Does Mind-Mindedness Matter? Understand the Connection Between Parenting Styles and Preschoolers' Internalizing and Externalizing Behavior Problems from a Cultural Lens

    Name(s): Creator (cre): Fu, Yuke, Thesis advisor (ths): Liu, Mowei, Degree committee member (dgc): Michael, Chan-Reynolds G, Degree committee member (dgc): Quan, Jeffry, Degree granting institution (dgg): Trent University
    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

    Do males really have it easier? The costs of reproduction in Sagittaria latifolia (Alismataceae)

    Year: 2024, 2024
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Gibson, Matthew Thomas, Thesis advisor (ths): Dorken, Marcel MD, Degree committee member (dgc): Emery, Neil NE, Degree committee member (dgc): Burness, Gary GB, Degree granting institution (dgg): Trent University
    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

    Assessing Human Bone Collagen Turnover Rate

    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

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

    Name(s): Creator (cre): Campbell, Michael John, Thesis advisor (ths): Mastromonaco, Gabriela F, Thesis advisor (ths): Burness, Gary, Degree committee member (dgc): McClelland, Grant B, Degree granting institution (dgg): Trent University
    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

    Models of Charged Domain Walls

    Year: 2024, 2024
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Carroll, Carson, Thesis advisor (ths): Atkinson, Bill, Degree granting institution (dgg): Trent University
    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
