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 ...

Mining operations in Ontario are subject to regulatory limits on effluent release into surrounding waterbodies designed to preserve aquatic life. However, said guidelines may not always be enough to prevent damage to the ...

In Canada, over 3 million freshwater lakes provide a wide range of ecological, financial, aesthetic, and public health services for their citizens, communities, and tourists. This is especially true for regions like ...

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 ...

Macrophytes are of significant importance to aquatic ecosystems, generating primary production in nearshore environments and providing physical structure and habitat for organisms in the littoral zone of lakes. Macrophyte ...

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 ...

Global climate change is occurring and observed warming patterns have had significant impacts on aquatic environments as trends in water temperature are closely related to trends in air temperature. In ectothermic organisms ...

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 ...

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) ...

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 ...
