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) ... -
Bioenergetic evaluation of a whole-lake nanosilver addition on Yellow Perch (Perca flavescens)
(2018)Nanosilver (nAg) is an antibacterial and antimicrobial agent. Its wide use in hundreds of commercial products and industrial applications suggests a high potential for release into the environment. Previous research indicates ... -
Brook Trout abundance and distribution at multiple spatial scales in Lake Superior tributaries
(2023)Brook Trout (Salvelinus fontinalis) populations and habitat conditions are adversely affected by anthropogenic impacts that could impact abundance and distribution of Brook Trout at different spatial scales. My goal was ... -
Changes in yellow perch diets associated with nanosilver exposure in freshwater lakes
(2017)Freshwater lake experiments on the effects of nanosilver were completed at the Experimental Lakes Area in northwestern Ontario. Since nanosilver has antibacterial properties it is expected to have negative effects on ... -
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 ... -
The effects of invasive dreissenid mussels on the offshore food web of Lake Simcoe, Ontario
(2019)Dreissenid mussels have successfully invaded North America, including the Great Lakes and their surrounding waterbodies. With their establishment, there have been many notable impacts including the rerouting of energy flow ... -
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 ... -
The effects of nanosilver on northern pike
(2018)Nanosilver (nAg) is an effective anti-microbial agent that is being increasingly used in consumer products. With such an expansive list of products incorporating nAg, the risk of environmental release is high. Studies ... -
Efficacy of a multimolecular extraction from formalin-fixed paraffin-embedded tissue
(2021)As the genetic basis and gene expression components are being discovered for an increasing number of diseases and disorders there is a rising interest in using multiomic approaches to better understand these conditions. ... -
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 ... -
Exploring the effect of predator experience on Yellow Perch (Perca flavescens) behaviour and predator recognition
(2020)Recreational and commercial fisheries are important resources that can be vulnerable to disruption by invasive species, particularly the introduction of top predators into water systems that have not previously supported ... -
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 ... -
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 ... -
Movement, resource use, and life history strategies of Black Bay Walley (Sander vitreus)
(2019)Resource distribution across the landscape can drive movement strategy selection, from sedentary to highly mobile individuals. When paired with other forms of analysis, movement ecology can provide insight into the resource ... -
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 ... -
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 ... -
Walleye (Sander vitreus) movement ecology in Lake Winnipeg, Canada
(2020)Identifying differences in movement behaviour and the variance in behavioural strategies that may exist across a single species occupying a heterogeneous landscape can provide valuable ecological and evolutionary insights; ...
