Abstract: <p>In order to effectively manage recreational fisheries, it is important to understand how the resource is being used. In this thesis, long-term creel census data, collected on Lake Opeongo in Algonquin Provincial Park, Ontario, Canada was used to assess fine-scale angler dynamics within a recreational Lake Trout (Salvelinus namaycush) fishery. The spatial distribution of angler reported… more Full Text: Understanding Angler Dynamics in a Recreational Lake Trout (Salvelinus namaycush) Fishery in Algonquin Provincial Park Using Long-Term Access Creel Data A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for …

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 …

This dissertation focuses on three experiments designed to test the hypothesis that plastic ability is limited by energetic constraints. Chapter 1 provides a general introduction to phenotypic plasticity research and the theoretical costs and limitations affecting the expression of plastic traits… more Full Text: CONSTRAINTS ON PHENOTYPIC PLASTICITY IN RESPONSE TO PREDATION RISK: CARRYOVER EFFECTS, MATERNAL INVESTMENT, AND THE STARVATION-PREDATION RISK TRADE-OFF A dissertation submitted to the Committee on Graduate Studies in partial fulfillment of the …

Abstract: <p>Recent declines in growth and condition of Great Lakes' lake whitefish (Coregonus clupeaformis) have been linked to ecosystem-wide changes stemming from the invasion of dreissenid mussels. To test the influence of invasive mussels on this commercially important coregonid species, we collected archived scale samples from ten Great Lake locations and analyzed long-term changes in… more Full Text: Widespread changes in growth, diet and depth distribution of lake whitefish (Coregonus clupeaformis) in the Great Lakes are linked to invasive dreissenid mussels A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the …
