Ecosystem and Watershed Ecology of Freshwater and Marine Ecosystems
My long-term research interest is to understand and model nutrient-foodweb dynamics of freshwater and marine ecosystems, and associated patterns of water quality, fisheries productivity, fate and transport of nutrients, energy and contaminants along aquatic foodwebs, and aquatic diversity. During the last decade, my research team has been approaching these fundamental ecological concepts and theories using ecosystem-level projects in coastal and interior BC, Alaska, northern Quebec and Ontario. Some of these projects are: nutrient limitation of aquatic productivity in coastal and interior lakes, delineation of aquatic foodweb structure and sources of energy along aquatic foodwebs using stable isotope geochemistry, linkages among foodweb structure, energy transfer efficiency and Hg accumulation in plankton and fish, ecosystem level impacts of fish farm on contaminants in traditional seafoods of aboriginal people, fish farm impacts on sea lice infection of juvenile Pacific salmon, nutrient-foodweb ecology of sockeye salmon ecosystems in Alaska and BC, foodweb dynamics and trophic interactions among juvenile Pacific salmon in the Bering Sea Ecosystem, resource partitioning between brook trout and juvenile Atlantic salmon in northern Québec streams, and the impact of selective sport fishing on foodweb structure, resource allocation and Hg accumulation in lake trout of selected Ontario lakes.
Besides these, my major interest has always been to link ecological understanding to aquatic resource management, and sustainable clean and healthy water for public health and safety. To achieve these, we have been working in partnership with several regional water supply authorities and over 20 communities in BC, and 16 aboriginal communities across Canada, and developing science and decision-making tools to reduce microbial and chemical health risks in source and tap water through best land- and water-use practices, optimization of disinfection byproducts and through tracking ssources of microbial and chemical pollution of source water. Our current research interest is also on the quality of water in the rural and slump communities in under-developed countries like Bangladesh, Haiti and Cambodia, where we are testing how the availability of safe household water leads to improved health and childhood education.
