Abstract: <p>The present study examined the understanding and behaviours relating to sexual consent on, and offline among men who have sex with men (MSM) and heterosexual men internationally using a convergent parallel mixed-methods approach. Men of both sexual orientation groups presented challenges with negotiating sexual consent, and this was especially true if they scored higher on aggressive… more Full Text: TRENT UNIVERSITY Peterborough, Ontario, Canada “JUST SAY YES” - SEXUAL CONSENT AND BOUNDARY SETTING ON-AND OFFLINE: AN INTERNATIONAL PERSPECTIVE OF MEN OF VARYING SEXUAL ORIENTATIONS A thesis submitted to the committee of Graduate Studies in partial …

Abstract: <p>Damage to the hippocampus (HPC) typically causes retrograde amnesia for contextual fear conditioning. Reinstating the conditioning over several sessions, however, can mitigate the retrograde amnesic effects. Reinstatements, thus, establish a sufficiently strong memory in non-HPC systems to no longer require the HPC for expression, meaning that it has become HPC independent. This thesis… more Full Text: NON-HIPPOCAMPAL MEMORY SYSTEMS CONTRIBUTING TO REINSTATED CONTEXT MEMORY 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 TRENT …

Abstract: <p>Recently, a distinction has been made between cognitive theory of mind, the ability to make inferences about other's beliefs and thoughts, and affective theory of mind, the ability to make inferences about other's emotional states. The purpose of this study is to determine if the distinction between cognitive and affective theory of mind is developmentally appropriate and… more Full Text: COGNITIVE AND AFFECTIVE THEORY OF MIND IN CHILDREN AND YOUNG ADOLESCENTS 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 TRENT …

Abstract: <p>Total phosphorus (TP) concentrations have declined in many lakes and streams across south- central Ontario, Canada over the past three decades and changes have been most pronounced in wetland-dominated catchments. In this study, long-term (1980-2007) patterns in TP concentrations in streams were assessed at four wetland-dominated catchments that drain into Dickie Lake (DE) in south-… more Full Text: IMPACT OF WETLAND DISTURBANCE ON PHOSPHORUS LOADINGS TO LAKES 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 …

Abstract: <p>Migratory and sedentary ecotypes are phenotypic distinctions of woodland caribou.

Abstract: <p>Most delphinids produce narrowband frequency-modulated whistles with a high level of plasticity to communicate with conspecifics. It is important to understand geographic variation in whistles as signal variation in other taxa has provided insight into the dispersal capabilities, genetic divergence and isolation among groups, and adaptation to ecological conditions.

Abstract: <p>Trinucleotide repeats (TNRs) are a class of highly polymorphic microsatellites which occur in neutral and non-neutral loci and may provide utility for individual- and population-identification. Exonic trinucleotide motifs, in particular, offer additional advantages for non-human species that typically utilize dinucleotide microsatellite loci. Specifically, the reduction of technical… more Full Text: Exonic Trinucleotide Microsatellites: Applying Genomic and Bioinformatic Techniques to Wildlife Forensic Science 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>Ustilago maydis is a basidiomycete smut fungus and the causal agent of common smut of corn. Disease progression and fungal development in this pathogen occur in planta, terminating in the production of dormant teliospores. Dormant spores of many fungi are characterized by reduced metabolic activity, which is restored during spore germination. The transition out of dormancy requires the… more Full Text: NATURAL ANTISENSE TRANSCRIPTS TO NUCLEUS-ENCODED MITOCHONDRIAL GENES ARE LINKED TO Ustilago maydis TELIOSPORE DORMANCY A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science …
