    Biogeochemical Responses to a Non-Industrial Wood Ash Addition in a South-Central Ontario Forest

    Year: 2024, 2024
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Conquer, Shelby M., Thesis advisor (ths): Watmough, Shaun A., Degree committee member (dgc): Yan, Norman D., Degree committee member (dgc): Eimers, M. Catherine, Degree granting institution (dgg): Trent University
    Abstract: <p>Recovery of forest soils from chronic acidification can be enhanced with the use of non-industrial wood ash (NIWA). Non-industrial wood ash is alkaline and contains high concentrations of macronutrients, but trace metal concentrations must be evaluated to limit risk of metal toxicity following application. Additionally, understanding how different forest ecosystem components respond to… more

    Legacy Effects Associated with the World's Largest Ongoing Liming and Forest Regeneration Program in Sudbury, Ontario, Canada

    Year: 2021, 2021
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Kellaway, Edward James, Thesis advisor (ths): Watmough, Shaun A., Degree committee member (dgc): Eimers, M. Catherine, Degree committee member (dgc): Basiliko, Nathan, Degree granting institution (dgg): Trent University
    Abstract: <p>Soil and tree chemistry were measured across 15 limed sites that were established 14 to 37 years ago within the Sudbury barrens in Ontario, along with two unlimed pre-treatment condition reference sites and an unlimed remnant pine forest. Soil pH and base cation (calcium (Ca), magnesium (Mg), and potassium (K)) concentrations were elevated in surface organic [FH] horizons up to 37-years… more

    Patterns of Vegetation Succession on Nickel-Copper Mine Tailings near Sudbury, Ontario

    Year: 2019, 2019
    Member of: Trent University Graduate Thesis Collection
    Name(s): Thesis advisor (ths): Watmough, Shaun A., Degree committee member (dgc): Basiliko, Nathan, Degree committee member (dgc): Hutchinson, Tom C., Degree granting institution (dgg): Trent University
    Abstract: <p>Natural establishment of vegetation on mine tailings is generally limited. Understanding the processes leading to vegetation germination and the survival mechanisms that vegetation species employ in these harsh environments is critical to future remediation efforts. As metalliferous mine tailings are generally nutrient-poor, high in harmful metals, and acidic, vegetation species require… more

    Effects of road salt sodium on soil: the influence of parent material

    Year: 2016, 2016
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Croucher, Kelli-Nicole, Thesis advisor (ths): Eimers, Catherine M., Degree committee member (dgc): Watmough, Shaun A., Degree committee member (dgc): Buttle, Jim, Degree granting institution (dgg): Trent University
    Abstract: <p>While previous studies have focused on how road salt affects water quality and vegetation, limited research has characterized road salt distribution through soil and the resulting impacts. The potential for sodium (Na+) to be retained and impact soil physical and chemical properties is likely to vary depending on the soil's parent material, and more specifically on the extent of… more

    Early Responses of Understory Vegetation to Above Canopy Nitrogen Additions in a Jack Pine Stand in Northern Alberta

    Year: 2014, 2014
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Melong, Nicole Victoria, Thesis advisor (ths): Watmough, Shaun A., Degree committee member (dgc): Sager, Eric P.S., Degree committee member (dgc): Emery, Neil R.J., Degree granting institution (dgg): Trent University
    Abstract: <p>Abstract</p><p>Early Responses of Understory Vegetation After One Year of Above Canopy Nitrogen Additions in a Jack Pine Stand in Northern Alberta</p><p>Nicole Melong</p><p>Nitrogen (N) emissions are expected to increase in western Canada due to oil and gas extraction operations. An increase in N exposure could potentially impact the surrounding boreal… more
