Abstract: <p>Microplastics, plastic particles less than 5 mm in diameter, are ubiquitous in the environment. This study estimated the abundance of microplastics (MP) in atmospheric deposition from four background monitoring stations in Muskoka-Haliburton, south-central Ontario, Canada and quantified the fate of microplastics to three background headwater lake catchments in Muskoka-Haliburton.… more Year: 2022, 2022

Abstract: <p>Human-wildlife interactions are inevitable and lead to decisions about wildlife. The current research investigated what demographic and psychological factors influence decisions in wildlife management. Also, a new measure, the Tolerance for Wildlife Scale, was developed. A student sample (n = 329) and a community sample (n = 213) completed measures on their nature relatedness,… more Year: 2022, 2022

Abstract: <p>Physical activity and classroom design changes are beneficial means to reduce stress, and enhance well-being. Results across some studies however, are mixed. Shanker Self-Reg™ supports the use of physical equipment and design as a means of managing arousal and tension levels. Previous research lacks rich description of educators' understanding of equipment and design, Self-Reg, and… more Year: 2022, 2022

Abstract: <p>Epilepsy is associated with a variety of cognitive, emotional, and pain-related symptoms, such as impaired memory and learning, increased risk of anxiety and depression, and increased pain sensitivity. Unfortunately, these symptoms are generally untreated with typical pharmacological interventions, which tend to target seizure activity (i.e., ictogenesis) and not the subsequent… more Year: 2022, 2022

Abstract: <p>Mining and resource development are growing industries in the Arctic, resulting in increased conflict with wildlife. Best practices for mitigation require an understanding of the potential ecological effects. One such effect concerns the flooding of terrestrial bird habitat from dewatering of lakes during mining pit development. I first assessed the efficacy of bird deterrents to… more Year: 2022, 2022

Abstract: <p>Maximum permitted SO2 emissions from an aluminum smelter in Kitimat, B.C., increased after modernization in 2015. An increase in acidic deposition can potentially acidify forest soils. Monitoring was conducted at two long-term soil monitoring plots at near (7 km) and far (41 km) sites downwind from the smelter. Change in soil properties was assessed between 2015 and 2018: for the near… more Year: 2022, 2022

Abstract: <p>Memories which typically require the hippocampus (HPC) can become represented in structures outside of the HPC, and therefore resistant to HPC damage, but, the properties of these memories are poorly understood. Some research has suggested that the HPC continually contributes to memories that are resistant to hippocampal damage, and without this support, they are weaker and more… more Year: 2022, 2022

Abstract: <p>Similar to other shorebird trends around the world, the Piping Plover population (Charadrius melodus circumcinctus) is projected to decline if concerted conservation efforts are relaxed. To date, there is insufficient understanding of the connection between habitat type, prey abundance, and chick behaviour of the Piping Plover breeding population in Ontario. The aim of my thesis was to… more Year: 2022, 2022

Abstract: <p>Medication used to treat human illness is one of the greatest developments in human history. In Canada, prescription drugs have been developed and made available to treat a wide variety of illnesses, from infections to heart disease and so on. Records of prescription drug fulfillment at coarse Canadian geographic scales were obtained from Health Canada in order to track the use of these… more Year: 2022, 2022

Abstract: <p>Walleye (Sander vitreus) are an ecologically and economically significant fish harvestedby recreational and commercial fisheries across Ontario. Adult Walleye are piscivores, but
anecdotal evidence from anglers suggests that Walleye often target aquatic insects such as
mayfly larvae (Ephemeroptera). My research examined the diet of Walleye caught from May to
September in Lake St. Joseph… more Year: 2022, 2022

Abstract: <p>The present study investigated the lived-experiences of individuals with workplace mental health injuries to better understand the thoughts, emotions, and behavioural processes that promote or inhibit help-seeking. This research investigated the interactions and relationships with relevant stakeholders and how they influence help-seeking. Qualitative methodology was employed by… more Year: 2022, 2022

Abstract: <p>AbstractDifferences and similarities in exploration and risk-taking behaviours
of two Myotis bat species.

Behaviours that are repeatable across circumstances and time determine an individual's personality. Personality and behavioural variation are subject to selective pressures, including risks related to the use of different habitat types. I explored the… more Year: 2022, 2022

Abstract: <p>Paramedic data has significant potential for research. Paramedics see many patients every year and collect a wide variety of crucial data at each encounter. This data is rarely used for good reason: it's messy and hard to work with. But like theunderdog character in a classic movie, with a little bit of work and a lot of understanding, paramedic data has significant potential to… more Year: 2022, 2022

Abstract: <p>Habitat loss and fragmentation have significantly contributed to amphibian population declines, globally. Evaluating the state of remaining habitat patches can prove to be beneficial in identifying areas to prioritize in conservation efforts. Pelee Island, Ontario is home to a complex of salamanders including small-mouthed salamanders (Ambystoma texanum), blue-spotted salamanders (A.… more Year: 2022, 2022

Abstract: <p>Increased plant size is expected to have negative consequences for mating by increasing pollen transfer among the same plant. However, recent theoretical studies have demonstrated that this may not be true for clonal plants. Instead, clonal expansion could enhance outcrossing opportunities without increasing selfing by reducing distances to potential mates. I investigated how the spatial… more Year: 2022, 2022

Abstract: <p>Studies that have investigated the relation between social anxiety and theory of mind or executive function have shown that individuals with deficits in these cognitive processes have high levels of social anxiety. However, methodological problems make past findings questionable and difficult to interpret. The current study investigated whether deficits in theory of mind and executive… more Year: 2022, 2022

Abstract: <p>The neuronal ceroid lipofuscinoses (NCLs), commonly known as Batten disease, are a family of inherited neurodegenerative lysosomal storage disorders. CLN7 disease is a subtype of NCL that is caused by mutations in the MFSD8 gene. MFSD8 encodes a lysosomal transmembrane protein that is predicted to play a role in transporting small substrates across membranes. However, little is known… more Year: 2022, 2022

Genetic network approaches allow the analysis
of genetic information with flexibility and few prior assumptions. In chapter one, I tested
the ability of individual-based genetic networks to detect fine-scale structure and
connectivity in relation to sampling efforts. My… more
