Abstract: <p>Lake whitefish (Coregonus clupeaformis) recruitment has declined substantially in several regions of the Laurentian Great Lakes since the establishment of non-native dreissenid mussels in the early 1990's. In Lake Huron, the reasons for the observed recruitment declines are currently unknown and there is limited knowledge about larval life stage. In our study, we determined whether… more Full Text: Larval lake whitefish (Coregonus clupeaformis) recruitment dynamics in Lake Huron 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 …

I used generalized linear mixed models to determine the factors affecting between-year variation in fall fidelity and the habitat selection in movement paths. I assessed second and third-order habitat preference by… more Full Text: Yearly variation in fall movements of adult female American black bears (Ursus americanus) in central Ontario, Canada 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>A species of concern is caribou (Rangifer tarandus), a species in decline across most of the circumpolar North, including the island of Newfoundland. Resource exploitation across caribou ranges is projected to accelerate in the coming decades as oil extraction, roads, forest harvesting, and mining encroach upon their habitat. Hydroelectric corridors, in particular, are anticipated to… more Full Text: THE EFFECTS OF HYDROELECTRIC CORRIDORS ON THE DISTRIBUTION OF FEMALE CARIBOU (Rangifer tarandus) ON THE ISLAND OF NEWFOUNDLAND A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfilment of the Requirements for the Degree of Master of …
