Below are some brief descriptions of ongoing projects in the CEE lab.
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 […]
It is becoming apparent that activity, movement and habitat use are a major component of fish life histories, but are rarely accounted for when considering life history relationships and tradeoffs generally. 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 […]
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. Haley Macleod is […]
At the IISD-ELA, we have initiated SHRRIMP; the Stenotherm Habitat Restoration through RecolonIzation of Mysis Project. The freshwater shrimp, Mysis diluvania, occupies many deep, stratified inland lakes on the boreal shield. It is a glacial relict species, and widely considered to be a “keystone” ecological species with regards to it’s effects in shaping zooplankton communities […]
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 […]
Recent investigations have demonstrated that invasive species (driessenids, Bythotrephes) can have potentially negative impacts on the growth of percid fishes in Minnesota and Wisconsin lakes. Current research is investigating the impacts of spiny water flea invasion on the growth and contaminant accumulation patterns of Walleye in Quetico Park, with generous support from the Quetico Foundation.
