Physical habitat associations of fish species in the Kivalliq region of Nunavut, Canada
(2020)
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 invasion of dreissenid mussels into Lake Simcoe and their effect on benthic invertebrates
(2021)
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 ...
Abundance, transportation, and preservation of Mysis diluviana eDNA in freshwater ecosystems
(2021)
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) ...
Evaluating the utility of a point of care device to assess physiological differences among wild boreal fishes
(2022)
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 ...
Salmonid thermal habitats in Lake Superior tributaries
(2020)
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 spiny water flea (Bythotrephes cederströmii) and their impacts on young-of-year walleye (Sander vitreus) growth
(2022)
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 ...
The effects of climate change on the growth and spawning phenology of fishes in aquatic boreal environments
(2022)
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 ...
Utilization of hydrodynamic modeling in predicting water quality and Brook Trout habitat: reclamation of a mine impacted Boreal Shield Lake
(2020)
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 ...
The effect of cottage development on aquatic macroinvertebrate communities and water quality in central Ontario lakes
(2023)
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 ...
Effects of macrophyte cutting on a whole lake ecosystem
(2023)
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 ...
