Environmental DNA (eDNA) detection has been proposed as a potential method for determining the presence, abundance, and biomass of species within aquatic habitats. However, it is unclear what spatial scale(s) eDNA ...

The rapidly accumulating post-consumer polyethylene terephthalate (PET) plastics pose a great threat to our environment as they constitute one of the most used products in our day-to-day life. As a result, degradation ...

Long-lived species such as turtles may appear to have healthy persistent populations if adults are consistently observed; however, study of size structures can reveal declining populations left vulnerable by limited ...

Scope: In eastern Canada, black spruce (Picea mariana)-Kalmia angustifolia forest revert into forest, or become Kalmia heath, or Kalmia-spruce shrub savannah (SS) depending on fire severity. My main research objective ...

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; ...

Heavy metal concentrations (As, Cd, Cr, Cu, Ni, Pb, and Zn) were investigated in water, peat, and macrophytes across three fens in Central Ontario in relation to the water parameters and peat properties to elucidate the ...

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) ...

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 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 ...
