    Year: 2022, 2022
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Steadman, Elizabeth Amber, Thesis advisor (ths): Nol, Erica, Degree committee member (dgc): Smith, Paul A, Degree committee member (dgc): Freeland, Joanna, Degree granting institution (dgg): Trent University
    Abstract: <p>Similar to other shorebird trends around the world, the Piping Plover population (Charadrius melodus circumcinctus) is projected to decline if concerted conservation efforts are relaxed. To date, there is insufficient understanding of the connection between habitat type, prey abundance, and chick behaviour of the Piping Plover breeding population in Ontario. The aim of my thesis was to… more

Records of prescription drug fulfillment at coarse Canadian geographic scales were obtained from Health Canada in order to track the use of these… more

    The Contributions of Mayflies (EPHEMEROPTERA: HEXAGENIA SPP.) and Other Invertebrates to the Seasonal Diet of Walleye (PERCIDAE: SANDER VITREUS)

    Year: 2022, 2022
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Ricker-Held, Ayden, Thesis advisor (ths): Beresford, Dave, Degree committee member (dgc): de Kerckhove, Dak, Degree committee member (dgc): Wilson, Chris, Degree granting institution (dgg): Trent University
    Abstract: <p>Walleye (Sander vitreus) are an ecologically and economically significant fish harvestedby recreational and commercial fisheries across Ontario. Adult Walleye are piscivores, but
    anecdotal evidence from anglers suggests that Walleye often target aquatic insects such as
    mayfly larvae (Ephemeroptera). My research examined the diet of Walleye caught from May to
    September in Lake St. Joseph… more

    Laura Michele Scott
    Behaviours that are repeatable across circumstances and time determine an individual's personality. Personality and behavioural variation are subject to selective pressures, including risks related to the use of different habitat types. I explored the… more

    Application of Data Science to Paramedic Data

    Year: 2022, 2022
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Smith, (John) Chris, Thesis advisor (ths): Burr, Wesley S, Degree committee member (dgc): Leyenaar, Matthew S, Degree committee member (dgc): Chan-Reynolds, Michael, Degree granting institution (dgg): Trent University
    Abstract: <p>Paramedic data has significant potential for research. Paramedics see many patients every year and collect a wide variety of crucial data at each encounter. This data is rarely used for good reason: it's messy and hard to work with. But like theunderdog character in a classic movie, with a little bit of work and a lot of understanding, paramedic data has significant potential to… more

    Name(s): Creator (cre): Smith, Graeme, Thesis advisor (ths): Murray, Dennis, Thesis advisor (ths): Hossie, Thomas, Degree committee member (dgc): Nol, Erica, Degree granting institution (dgg): Trent University
    Abstract: <p>Habitat loss and fragmentation have significantly contributed to amphibian population declines, globally. Evaluating the state of remaining habitat patches can prove to be beneficial in identifying areas to prioritize in conservation efforts. Pelee Island, Ontario is home to a complex of salamanders including small-mouthed salamanders (Ambystoma texanum), blue-spotted salamanders (A.… more

    Clonal structure and mating patterns in a natural population of Sagittaria latifolia

    Year: 2022, 2022
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Stephens, Samantha, Thesis advisor (ths): Dorken, Marcel, Degree committee member (dgc): Emery, Neil, Degree committee member (dgc): Bowman, Jeff, Degree granting institution (dgg): Trent University
    Abstract: <p>Increased plant size is expected to have negative consequences for mating by increasing pollen transfer among the same plant. However, recent theoretical studies have demonstrated that this may not be true for clonal plants. Instead, clonal expansion could enhance outcrossing opportunities without increasing selfing by reducing distances to potential mates. I investigated how the spatial… more

    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Whitsitt, Jonathan, Thesis advisor (ths): Im-Bolter, Nancie, Degree granting institution (dgg): Trent University
    Abstract: <p>Studies that have investigated the relation between social anxiety and theory of mind or executive function have shown that individuals with deficits in these cognitive processes have high levels of social anxiety. However, methodological problems make past findings questionable and difficult to interpret. The current study investigated whether deficits in theory of mind and executive… more

    Mfsd8 regulates growth and multicellular development in Dictyostelium discoideum

    Abstract: <p>The neuronal ceroid lipofuscinoses (NCLs), commonly known as Batten disease, are a family of inherited neurodegenerative lysosomal storage disorders. CLN7 disease is a subtype of NCL that is caused by mutations in the MFSD8 gene. MFSD8 encodes a lysosomal transmembrane protein that is predicted to play a role in transporting small substrates across membranes. However, little is known… more

    Abstract: <p>Understanding genetic structure, connectivity, and movement of a species iscritical to management and conservation. Genetic network approaches allow the analysis
    of genetic information with flexibility and few prior assumptions. In chapter one, I tested
    the ability of individual-based genetic networks to detect fine-scale structure and
    connectivity in relation to sampling efforts. My… more

    Year: 2022, 2022
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Holt, Ryan, Thesis advisor (ths): Bowman, Jeff, Thesis advisor (ths): Davy, Christina M, Degree committee member (dgc): Koen, Erin L, Degree granting institution (dgg): Trent University
    Abstract: <p>Roosts offer bats protection from predators, shelter from external environmental conditions, and a space where sociality, mating, and the rearing of young can occur. However, knowledge gaps still remain for many forest roosting species, such as the little brown bat (Myotis lucifugus) surrounding what roosts are selected, and what variables are influential at differing scales of selection… more

    Name(s): Creator (cre): Leuzzi, Marisa, Thesis advisor (ths): Agostino, Alba, Thesis advisor (ths): Im-Bolter, Nancie, Degree granting institution (dgg): Trent University
    Abstract: <p>Adolescence is a time when young people focus their attention on setting and pursuing long-term goals. Contemporary approaches of identity development focus on three pivotal processes underlying the identity formation process and the maintenance of one's identity (e.g., core values, etc.). These processes are commitment (commitments to a goal), in-depth exploration (exploration of… more
