Year: 2025, 2025
Member of: Trent University Graduate Thesis Collection
Name(s): Creator (cre): Foley, Kaylen, Thesis advisor (ths): Watmough, Shaun, Degree committee member (dgc): Power, Ian, Degree committee member (dgc): Thompson, Karen, Degree granting institution (dgg): Trent University
Abstract: <p>Forests play a critical role in the global carbon cycle, acting as carbon sinks that remove and store an estimated 0.4 to 4.1 Pg of atmospheric carbon annually. However, historical acid deposition and timber harvesting have disrupted nutrient cycles, leading to nutrient-deficient soils that hinder tree growth, particularly for sugar maple (Acer saccharum), a keystone species in Ontario… more

Investigation of Dynamics of Particulate Transport under Varying Climate Conditions

23232-Thumbnail Image.png
Year: 2024, 2024
Member of: Trent University Graduate Thesis Collection
Name(s): Creator (cre): Schweighofer, Christopher John, Thesis advisor (ths): McKenna Neuman, Cheryl, Degree committee member (dgc): Power, Ian, Degree committee member (dgc): Aherne, Julian, Degree granting institution (dgg): Trent University
Abstract: <p>A key knowledge gap in aeolian transport research concerns the adjustment of saltation processes to the extreme conditions found within high-latitude regions. A series of wind tunnel experiments were carried out under full climate control and over a wide range in humidity. Particle entrainment and transport within shearing flows of varied wind speed were monitored over beds of varied… more

Short-Term Impacts of Agricultural Land Use Change on Soil Health and Nitrogen Cycling Microbial Communities

23194-Thumbnail Image.png
Year: 2024, 2024
Member of: Trent University Graduate Thesis Collection
Name(s): Creator (cre): Kularathne, Ridmani Hansika, Thesis advisor (ths): Thompson, Karen, Degree committee member (dgc): Eimers, Catherine, Degree committee member (dgc): Power, Ian, Degree granting institution (dgg): Trent University
Abstract: <p>Glyphosate burndown and tillage, followed by the cultivation of cash crops, are frequently used techniques in LUC from perennial cropping systems (PS) to annual cropping systems (AS). Agricultural LUC can result in the loss of soil nitrogen (N) via emission of nitrous oxide (N2O), a potent greenhouse gas (GHG). The purpose of this thesis is to investigate the short-term impacts of… more
