Aquatic Food Web Ecology Lab, Dalhousie University

Research in the Aquatic Food Web Ecology Lab based at Dalhousie University in Halifax, Nova Scotia, Canada, focuses on the consequences of biodiversity loss to the functioning and stability of aquatic food webs. All of our work is done in a food web context, which means that its not just the numbers of species that we are interested in, but also the structure of the food webs in which those species are embedded. Most of our work is done in aquatic microcosms, small container ecosystems in which we can assemble food webs and then subject them to various types of disturbance regimes . We also use mathematical models to run "in silico" experiments, otherwise known as computer simulations, to study problems that are too complex or just not possible to conduct in natural systems.

baby salmon need trees!


Next time you are driving the "Sea to Sky" highway up to Whistler take a moment to think of the salmon fry and the foreshore development. Chum salmon fry NEED trees!
