Abstract: <p>Anthropogenic activities such as human activity and livestock grazing are responsible for the global rise in disturbance impacts on wildlife and may underlie regional changes in biodiversity and ecosystem dynamics. Few studies have tried to disentangle the effects of different anthropogenic activities on wildlife behaviour, leaving a major gap in our understanding of conservation and… more Full Text: Robust assessment of changes in wild mammal occupancy and activity relative to livestock and human disturbance.

Abstract: <p>In recent decades, declining calcium concentrations have been reported throughout lakes across the southern edge of the Canadian Shield. This raises concern as Daphnia populations have shown to be decreasing as they require calcium not only for survival but to mitigate predation risks. Therefore, the purpose of my thesis was to study the adaptability of Daphnia under calcium limitation… more Full Text: CALCIUM STRESS IN DAPHNIA PULICARIA AND EXPOSURE TO PREDATOR-DERIVED CUES: MAKING A BAD SITUATION WORSE?

Abstract: <p>This study examined the relation between complexity of pretend play during preschool and early academic skills two years later. Preschool children (n =19), aged 3 years, were observed during self-directed free play, which was then coded for complexity of symbolic thought with respect to symbolic agent (ability to direct self or other's play) and symbolic substitution (abstractness… more Full Text: Peers, Props & Play: Complexity of Pretend Play and Early Academic Skills A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Degree of Master of Science in the Faculty of Arts and Science TRENT UNIVERSITY Peterborough, …

Abstract: <p>Trait Emotional Intelligence (TEI) plays an important role in the health and wellness of children and adolescents. Not surprisingly, the literature on TEI and youth has expanded dramatically. Although the quality of this work continues to be uneven due to the continued proliferation of TEI-related measures with questionable psychometric features. One over-looked TEI measure in the field… more Full Text: i DEVELOPING SOCIAL-EMOTIONAL COMPETENCIES IN YOUTH: VALIDATION OF THE SHORT FORM FOR THE EMOTIONAL QUOTIENT INVENTORY YOUTH VERSION (EQ-i:YV-S) A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the …

Abstract: <p>Past research has predominately supported an association between insecure attachment and substance use. More recent research has found that while individuals with secure attachment may use substances, they do so with less risk. The current study attempted to replicate the finding regarding secure attachment and substance use and examined the motivational drives behind why students use… more Full Text: DRINK MY BEER, SMOKE MY WEED, MY GOOD FRIENDS ARE ALL I NEED: AN EXPLORATION OF HOW ATTACHMENT-MOTIVATION RELATIONSHIPS MAY INFLUENCE SUBSTANCE USE A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Degree of Master of …

Abstract: <p>Identifying population declines and mitigating biodiversity loss require reliable monitoring techniques, but complex life histories and cryptic characteristics of anuran species render conventional monitoring challenging and ineffective. Environmental DNA (eDNA) detection is a highly sensitive and minimally invasive alternative to conventional anuran monitoring. In this study, I… more Full Text: Comparative efficacy of eDNA and conventional methods for monitoring wetland anuran communities A thesis submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirement for the Degree of Master of Science in the Faculty of Arts …

Abstract: <p>The onset of neurodegenerative diseases such as Alzheimer's disease (AD) and amyotrophic lateral sclerosis (ALS) are typically characterised by the aggregation of protein biomarkers into cytotoxic fibrils. Novel means of analysing these biomarkers are needed to expand the literature toward earlier diagnosis of these conditions. Electrochemical sensors could offer the sensitivity and… more Full Text: ELECTROCHEMICAL BIOSENSORS FOR NEURODEGENERATIVE DISEASE BIOMARKERS: INVESTIGATIONS INTO THE ORIGIN AND DIAGNOSIS OF ALZHEIMER’S DISEASE AND AMYOTROPHIC LATERAL SCLEROSIS A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of …

Abstract: <p>Cardiovascular disease (CVD) prevention, treatment and outcomes in women remain largely inequitable globally. Unique sex-specific stages of life, including pregnancy conditions, and their influence on cardiac risk is a growing area of research (Norris et al., 2020). For example, preeclampsia is strongly associated with CVD risk. This connection has led to prevention interventions such as… more Full Text: Women’s Lived Experience of Risk in Pregnancy A thesis submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science TRENT UNIVERSITY Peterborough, Ontario, …
