More than 15 years have passed since Canada's Species at Risk Act was enacted. To
evaluate scientific progress in support of the Act, we identified research accomplishments up …

Thermal tolerance and associated mechanisms are often tested via the critical thermal
maximum (CT max). The agitation temperature is a recently described thermal limit in fishes …

Metabolic rate and hypoxia tolerance are highly variable among individual fish in a stable
environment. Understanding the variability of these measures in wild fish populations is …

Fish gills are complex organs that have direct contact with the environment and perform
numerous functions including gas exchange and ion regulation. Determining if gill …

Anthropogenic stressors such as agriculture and urbanization can increase river turbidity,
which can negatively impact fish gill morphology and growth due to reduced oxygen in the …

Owing to climate change, most notably the increasing frequency of marine heatwaves and
long-term ocean warming, better elucidating the upper thermal limits of marine fishes is …

In thermally variable ecosystems, temperatures can change extensively on hourly and
seasonal timescales requiring ectotherms to possess a broad thermal tolerance (critical …

Marine ectothermic fishes—fishes that do not regulate internal body temperature
independent from the water temperature—are some of the most vulnerable organisms to …
