Although the frilled dogwinkle (Nucella lamellosa) is a well-studied intertidal snail, questions have remained regarding the purpose of some variations in shell form found commonly in individuals of this species. The function of axial lamellae, an external shell structure giving some individuals of this species a frilled appearance, has remained a mystery. As a part…
Appetite for destruction: Invasive European green crabs in Barkley Sound eat faster and grow bigger
Recreational fishing is popular throughout the world and has significant socioeconomic impacts. Catch-and-release fishing is beneficial for a number of reasons, but the immediate impact of hook removal is poorly understood. Melissa Thompson, a University of Alberta undergraduate student, during our 2017 Biology of Marine Fishes course (co-taught by Tim Higham and Sean Rogers), caught…

Multiple body parts must work together to accomplish a task. For example, the coordination of visual and locomotor systems is critical for animals that hunt for food. For fishes, both swimming and feedings systems must work together to capture prey. How this process impacts survival, or how it differs depending on ecological conditions, is…
I study the causes and consequences of biodiversity change in marine ecosystems, with the goal of developing science-based tools to inform conservation and restoration actions under global change. My students and I conduct collaborative research using a range of methods in the field and lab—behavioural observation, manipulative field experiments, theoretical and statistical models, and time series analyses along…
