Abstract: <p>Competition is known to impact population dynamics through both indirect and direct interactions, and direct interactions can often lead to injury in one or both parties. As such, response to injury through tissue regeneration can be important for surviving post-competitive interaction. However, the impacts of outside factors like temperature and genome size (e.g. polyploidy) are not… more Full Text: How Abiotic and Biotic Factors Can Alter the Competitive Landscape in an Aggressive Species Complex (Genus: Ambystoma) A thesis submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirement for the Degree of Master of Science in …

Abstract: <p>Blackfin Cisco (Coregonus nigripinnis), a deepwater cisco species once endemic to the Laurentian Great Lakes, was discovered in Algonquin Provincial Park in four lakes situated within a drainage outflow of glacial Lake Algonquin. Blackfin habitat preference was examined by analyzing which covariates best described their depth distribution using hurdle models in a multi-model approach.… more Full Text: HABITAT PREFERENCES AND FEEDING ECOLOGY OF BLACKFIN CISCO (COREGONUS NIGRIPINNIS) IN NORTHERN ALGONQUIN PROVINCIAL PARK A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science …

Abstract: <p>Nitrogen is a major constituent of agricultural fertilizers, and nitrogen inputs to stream water via runoff and groundwater lead to a variety of negative environmental impacts. In order to quantify the movement of nitrogen through aquatic food webs, fourteen streams with varying land uses across South-Central Ontario were sampled for two species of fish, freshwater mussels, and water for… more Full Text: CARBON AND NITROGEN ISOTOPE CHANGES IN STREAMS ALONG AN AGRICULTURAL GRADIENT A Thesis submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in …

Abstract: <p>My study was primarily focused on the comparison of life history traits between stocked American eel and their naturally recruited conspecifics in Lake Ontario and the upper St. Lawrence River (USLR/LO). I found that stocked eels experienced faster annual growth than their naturally recruited conspecifics and were comprised of a greater proportion of males. These findings indicate that… more Full Text: THE LIFE HISTORY STRATEGY, GROWTH, BODY CONDITION, AND DIET OF STOCKED AMERICAN EEL (Anguilla rostrata) IN THE UPPER ST.
