    Regional diet and isotopic niche of predatory fish following a regime shift in Lake Huron

    Year: 2024, 2024

    Name(s): Creator (cre): Taylor, Courtney Erin, Thesis advisor (ths): Dunlop, Erin S, Degree committee member (dgc): Lauzon, Ryan, Degree committee member (dgc): Raby, Graham, Degree committee member (dgc): Rennie, Michael, Degree granting institution (dgg): Trent University
    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

    Sex-specific spawning behaviour of lake whitefish in Lake Huron revealed by fine-scale acoustic telemetry

    Year: 2023, 2023

    Name(s): Creator (cre): Ryther, Camilla, Thesis advisor (ths): Dunlop, Erin S, Degree committee member (dgc): Lauzon, Ryan, Degree committee member (dgc): Raby, Graham D, Degree granting institution (dgg): Trent University
    Abstract: <p>Lake whitefish (Coregonus clupeaformis) are ecologically, economically, and culturally significant across their range, yet little is documented about the species' spawning behaviour. Recruitment of lake whitefish has dramatically declined over the past two decades across many regions of the Laurentian Great Lakes, most notably in lakes Huron and Michigan, prompting research efforts… more

    Eco-evolutionary Dynamics in a Commercially Exploited Freshwater Fishery

    Year: 2019, 2019

    Name(s): Creator (cre): Gobin, Jenilee, Thesis advisor (ths): Dunlop, Erin S, Thesis advisor (ths): Fox, Michael G, Degree committee member (dgc): Lester, Nigel P, Degree granting institution (dgg): Trent University
    Abstract: <p>Fisheries assessment and management approaches have historically focused on individual species over relatively short timeframes. These approaches are being improved upon by considering the potential effects of both broader ecological and evolutionary processes. However, only recently has the question been raised of how ecological and evolutionary processes might interact to further… more
