Projects

Below are some brief descriptions of ongoing projects in the CEE lab.

  • Variation in trophic ecology in Lake Superior

    Food web ecology Bioenergetics

    Lake Superior is one of the largest lakes in the world. While it can often be considered a homogeneous entity, in reality there is tremendous variation in the types of aquatic ecosystems it supports, and yet very little is known about how this variation affects rates of energy flow and the sources of energy among […]

  • Walleye habitat use

    Movement ecology

    The walleye population in Black Bay, Lake Superior, crashed in the mid-1960’s and has only shown signs of recovery within the past decade. To evaluate current restoration efforts and their impact on Walleye in Black Bay, we are examining the movement ecology of Walleye along the north shore of Lake Superior. This work is in […]

  • Predictors of fish productivity in boreal lakes

    Food web ecology

    We are using historical data form IISD-ELA on lakes that have undergone disturbance, as well as lakes with gradients of productivity to evaluate correlates and drivers of fish productivity. This is part of a larger effort involving researchers from the IISD-ELA,  University of Waterloo, Wilfrid Laurier University and the University of Manitoba.   Margaret Schweitzer is […]

  • Ecosystem-level effects of nanosilver release

    Contaminants Bioenergetics Food web ecology

    Nanosilver is an emerging contaminant with broad potential for environmental release; it is an antimicrobial that is in many, many consumer products and is easily released into wastewater streams through laundry (it’s in clothes, washing machines and detergents). It is clear that nanosilver acts differently on organisms than elemental silver, suggesting that a different set […]

  • Changes in the Lake Simcoe food web

    Food web ecology Bioenergetics

    Lake Simcoe is unique in that it is the only lake with legislation written regarding it’s protection. The Lake Simcoe food web has undergone numerous changes over the years, and our research has investigated primarily how it has changed as a result of species invasions. We have documented significant changes in the benthic communities in […]
