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 ...
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 ...
Neutrophils in the interface between innate and adaptive immunity in response to Haemophilus influenzae type a
(2022)
Haemophilus influenzae type a (Hia) is a bacterial human pathogen that has emerged as a
significant cause of invasive disease in Canadian Indigenous populations. Protection against
encapsulated bacteria such as Hia is ...
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 ...
Skeletal muscle adaptation in response to chronic oral corticosterone treatment in C57BL/6N mice
(2023)
Chronic exposure to elevated glucocorticoid levels represents a significant
concern for researchers, healthcare professionals, and the general public. In various
disorders and diseases (such as Cushing Syndrome and major ...
Pre-clinical assessment of the selective androgen receptor modulator RAD140 to increase muscle mass and bone mineral density
(2022)
Selective androgen receptor modulators (SARMs) are important hypertrophic
molecules that pose as potential treatments for many types of myopathy and osteopathy.
The aim of this study was to determine if the SARM RAD140 ...
