Understanding the variables affecting reproductive success can aid conservation of grassland species. I investigated 1) whether artificial nest experiments accurately estimate the impacts of cattle… more Full Text: THE EFFECTS OF LOCAL, LANDSCAPE, AND TEMPORAL VARIABLES ON BOBOLINK NEST SURVIVAL IN SOUTHERN ONTARIO 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 …

Abstract: <p>Upland Sandpipers (Bartramia longicauda), like many grassland birds, are undergoing population decline in parts of their range. Habitat fragmentation and change have been hypothesized as potential causes of decline. I used citizen-science occurrence data from Wildlife Preservation Canada's Adopt-A-Shrike Loggerhead Shrike (Lanius ludovicianus) program in conjunction with validation… more Full Text: DETECTABILITY AND ITS ROLE IN UNDERSTANDING UPLAND SANDPIPER (Bartramia longicauda) OCCURRENCE IN THE FRAGMENTED LANDSCAPE OF SOUTHERN ONTARIO A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the …

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. I investigated… more Full Text: REGIONAL DIFFERENCES IN THE WHISTLES OF AUSTRALASIAN HUMPBACK DOLPHINS (GENUS SOUSA) A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree …

Abstract: <p>Road mortality is one of the leading causes of global population declines in reptiles and amphibians. Stemming losses from reptile and amphibian road mortality is a conservation priority and mitigation is a key recovery measure. I developed a model of road mortalities relative to non-‐mortalities, based on predictors varying across space (road surface type, traffic volume, speed limit,… more Full Text: FACTORS AFFECTING ROAD MORTALITY OF REPTILES AND AMPHIBIANS ON THE BRUCE PENINSULA A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of …

Abstract: <p>Pacific Rim National Park Reserve's 16 km of coastal beaches attract many thousands of people and shorebirds every year. To identify locations where shorebirds concentrate and determine the impact of human activity and habitat characteristics on shorebirds, I conducted shorebird and visitor surveys at 20 beach sectors during fall migration in 2011 to 2013 and spring migration in… more Full Text: HUMAN ACTIVITY AND HABITAT CHARACTERISTICS INFLUENCE SHOREBIRD HABITAT USE AND BEHAVIOUR AT A VANCOUVER ISLAND MIGRATORY STOPOVER SITE A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of …
