    Host Population Immunogenetics in a Changing World: Signatures of Selection in the Context of Endemic and Invasive Diseases in Wildlife

    Year: 2025, 2025
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Baecklund, Tristan Mackenzie, Thesis advisor (ths): Kyle, Christopher J, Degree committee member (dgc): Donaldson, Michael, Degree committee member (dgc): Shafer, Aaron, Degree committee member (dgc): Brown, Glen, Degree granting institution (dgg): Trent University
    Abstract: <p>Heterogeneous environments impose discordant selective pressures on natural populations, where disparate biotic/abiotic factors and variable population connectivity, yield mosaic patterns of genetic variation on the landscape. The ability to maintain or change genetic mosaics of populations becomes key to persistence, as species increasingly need to adapt to rapidly changing… more

    Abstract: <p>Measuring biodiversity has become increasingly complex as biologists and ecologists have gradually learned more about how biotic systems are structured and interact. Given the wide range of tools, techniques and approaches now in use to quantify biological diversity, it is useful to consider different "dimensions of diversity" to classify these measurements and provide context… more

    Abstract: <p>Climate change is a major conservation concern, especially for many cold-adapted species. The rate of warming due to climate change will likely outpace adaptive responses, and many populations will likely need to rely on phenotypic plasticity to cope with environmental warming. It is currently unclear whether plasticity in physiological responses to warming will be sufficient to offset… more
