The designation of Thunder Bay’s Harbour as an Area of Concern (AOC) by the International Joint Commission prompted the need for Remedial Action Plans to improve historically significant habitats (RAP, 1991; RAP 2004). In ...

In recent years, human beings have done much damage to the lakes and wetlands, resulting in some irreversible effects. It is, therefore, necessary to restore and protect the remaining wetlands. The most representative ...

Understanding species interactions is critical to predicting the ecosystem-level impacts of anthropogenically-caused species extirpations. In particular, the loss of keystone species - those that have exceptionally large ...

The Canadian arctic and subarctic (areas north of 60° latitude) support distinct aquatic environments governed by the unique geomorphology and climate of the region. Historically, fish and fish habitat impacted by ...

The establishment of dreissenid mussels (zebra mussel, Dreissena polymorpha and the quagga mussel Dreissena rostriformis bugensis) in Lake Simcoe in 1997 and 2008, respectively, in Lake Simcoe has drastically altered ...

Environmental DNA (eDNA) has proven to be a valuable tool in detecting rare or invasive species, particularly within the Great Lakes and surrounding aquatic ecosystems. Recent work has shown that sedimentary eDNA (sedDNA) ...

With the increasing risk of anthropogenic impacts in boreal ecosystems there is a need for tools to rapidly assess impacts on organisms and properly inform resource managers. Though well-researched, the i-STAT a portable ...

For some potamodromous salmonid species, such as the Brook Trout, streams are a critical spawning habitat but also habitat for juveniles and stream residents to grow. Salmonids are coldwater fishes and cooler stream water ...

Invasive species are a major threat to aquatic ecosystems, costing an estimated $3.6 billion in impacts across Ontario. In particular, the predatory cladoceran Bythotrephes cederströmii (Bythotrephes hereafter) has had ...
