My interests are landscape-level predator prey relationships and the community and behavioral ecology of fish and bird species. My past and ongoing research has focused on the distributional linkage between prey fish and piscivorous birds.
My M.Sc. research through the University of Victoria, British Columbia, examined the habitat use of the Pacific sand lance (Ammodytes hexapterus), a fish species that is an important link between secondary producers and top marine predators in the Pacific Northwest. My research contributed to creating a better understanding of habitat use of an endangered seabird, the marbled murrelet (Brachyramphus marmoratus), for which sand lance is a main prey item.
For my Ph.D. research, I have transitioned from studying marine systems to freshwater lakes of Arctic Alaska. My project explores the diet and habitat use of the yellow-billed loon (Gavia adamsii) on the North Slope. The yellow-billed loon is a species of conservation concern. One of the ten rarest bird species in North America, this species’ nesting habitat is potentially sensitive to oil and gas development, and adults are exposed to potential impacts at-sea such as incidental catch in fisheries.
The distributions of prey fish over the thousands of lakes dotting North Slope landscape are potentially important in determining habitat use for nesting yellow-billed loons. To help understand what habitat features are important for breeding loons, I am using a habitat modeling approach to examine the distribution and structure of fish communities in lakes, and then using this information, along with other environmental factors, to model the habitat use of nesting yellow-billed loons. To mechanistically connect landscape associations between fish species and breeding birds, I am using molecular techniques to determine the diet composition of loons.
