Abstract: <p>There is a `universal' picture of a charged domain wall (CDW) in theoretical work, often depicted as residing in an infinite thickness film, charge neutral, and with no bias voltage applied. However, in experiment CDWs are shown with none of these assumptions. CDWs are produced in thin or ultra-thin films, the CDW is not charge neutral, and a bias voltage is being applied. We look… more Full Text: Models of Charged Domain Walls A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science.

To determine how shorebirds use migratory stopover sites, we tracked three species of shorebirds at two stopover sites in British Columbia, Canada from 2018-2021 during northward and southward migration using automated telemetry. Western Sandpipers (Calidris mauri) stayed longer… more Full Text: Length of stay and habitat use of shorebirds at two migratory stopover sites in British Columbia, Canada A thesis submitted to the Committee on Graduate Studies in partial fulfillment of the requirements for the degree of Master of Science in the Faculty …

Abstract: <p>ABSTRACT
Patients who undergo chemotherapy often complain of a persistent 'brain fog' that can be present up to years after treatment ends. This fog is expressed as marked impairments in areas of learning, memory and mental health. As it stands, researchers have yet to determine the mechanism at fault for these impairments. The present experiment investigates if the… more Full Text: The Effect of Systemic Temozolomide on Learning, Emotional Behaviour, and Hippocampal Synaptic Plasticity: Implications for chemotherapy-induced cognitive impairment A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the …

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 Full Text: SHORT-TERM IMPACTS OF AGRICULTURAL LAND USE CHANGE ON SOIL HEALTH AND NITROGEN CYCLING MICROBIAL COMMUNITIES A Thesis Submitted to the Committee on Graduate Studies In Partial Fulfillment of the Requirements for the Degree of Master of Science in the …

Abstract: <p>Advanced generation/backcrossed (non-F1) hybrids can be challenging to identify when their traits are similar to those of parental taxa, F1 hybrids, or both. This is particularly evident in the North American hybrid zone involving Typha latifolia, T. angustifolia, F1 T. × glauca and non-F1 hybrids. Cattails are challenging to differentiate based on gross morphological characteristics.… more Full Text: Accuracy and reliability of microscopic characteristics to identify Typha species and their hybrids A thesis submitted to the Committee on Graduate Studies in partial fulfilment of the requirements for the degree of Master of Science in the Faculty of …
