The association between watershed characteristics and mercury concentrations in fish of Northern Ontario lakes
Many landscape, limnological, and ecological factors synergistically affect the mercury cycle and subsequently influence total mercury (THg) concentrations in fish. In Chapter 1, the associations between watershed and lake ...
Impacts of Mysis diluviana extirpation on a whole lake ecosystem
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 ...
Physical habitat associations of fish species in the Kivalliq region of Nunavut, Canada
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 ...
Abundance, transportation, and preservation of Mysis diluviana eDNA in freshwater ecosystems
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) ...
