Atlantic salmon become thermally stressed when water temperatures exceed 23° C. To
alleviate this stress, they behaviourally thermoregulate by moving to patches of cold water …

Behavioural thermoregulation is a survival strategy that occurs in response to an
exceedance of thermal stress‐inducing thresholds. When salmonids experience …

Adult Atlantic salmon (Salmo salar) return to natal rivers several months before spawning
and during summer can be subjected to temperatures that exceed their upper temperature …

Climate change is expected to increase the frequency and magnitude of extreme thermal
events in rivers. The Little Southwest Miramichi River (LSWM) and the Ouelle River (OR) are …

Thermal refuges are becoming increasingly influential for dictating the population status and
spatial distribution of cold-water stenotherm salmonids in the mid-to southern extent of their …

In response to high summer river temperatures, salmonids avoid heat stress by making use
of discrete units of cold water termed thermal refuges. Although recent research has …

Summer water temperatures within many temperate rivers regularly surpass the incipient
lethal temperature for juvenile Atlantic salmon (c. 27° C), causing widescale abandonment …

There has been considerable focus on winter studies of Atlantic salmon Salmo salar parr
during the last two decades. However, a lack of knowledge exists about the linkage between …

Anthropogenic influences, including climate change, are increasing river temperatures in
northern and temperate regions and threatening the thermal habitats of native salmonids …

Temperature is important to fish in determining their geographic distribution. For cool-and
cold-water fish, thermal regimes are especially critical at the southern end of a species' …
