The research program of my group is broadly defined by the ecology of aquatic communities, currently ranging from amphibian populations of California, the Pacific Northwest, and the far north, to the river and lake food webs that support salmon populations from California to Alaska. We rely heavily on field-based experimental manipulations to tease apart the mechanistic underpinnings of ecological patterns, from species physiology to food web interactions. However, we are also fundamentally committed to the growing necessity for understanding the dynamics of individuals, populations, and communities at the broad spatial and temporal scales relevant to the conservation and management of aquatic systems. This kind of applied ecological problem-solving requires tailoring a combination of approaches to each particular question; from lab-based physiological assays, behavioural observations, manipulative field experiments, landscape-scale surveys, paleoecological reconstructions, population dynamics modeling, and importantly, the emerging quantitative challenge of drawing all of them together.
- Multidisciplinary synthesis of oil sands impacts
- Evaluating threats to alpine amphibians now and in the future
- Impacts of dams and altered hydrology on sentinel river taxa
- How do we minimize trade-offs between small hydropower development and species conservation and ecosystem services?
- Spatial variability in the importance of terrestrial-aquatic coupling for top predators in river food webs.
- Ultraviolet radiation impacts to amphibians
My lab is a founding member of the Earth2Ocean Research Group (www.earth2ocean.org) at Simon Fraser. As a group, we are committed to training students to be excellent individual researchers with a strong quantitative focus as well as skilled collaborators that are motivated by ecological and conservation problems that often exceed our individual specialties or capabilities.
