Concern over global climate change is widespread, but quantifying relationships between temperature change and animal fitness has been a challenge for scientists. Our approach to this challenge was to study migratory Pacific salmon (Oncorhynchus spp.), fish whose lifetime fitness hinges on a once‐in‐a‐lifetime river migration to natal spawning grounds. Here, we suggest that their thermal optimum for aerobic scope is adaptive for river migration at the population level. We base this suggestion… 

Aerobic scope increases throughout an ecologically relevant temperature range in coho salmon

Coho salmon do not conform to existing predictions about the temperature dependence of aerobic scope in Pacific salmon, suggesting that when attempting to understand thermal optima for Pacific salmon and other species across life stages, AS is a useful metric of oxygen transport capacity but other thermally sensitive physiological indices of performance and fitness should be considered in concert.

Thermal sensitivity and flow-mediated migratory delays drive climate risk for coastal sockeye salmon

Climate change is subjecting aquatic species to increasing temperatures and shifting hydrologic conditions. Understanding how these changes affect individual survival can help guide conservation and

The upper limit for heart rate may emerge as a valuable, but simple predictor of optimal temperature in active animals, opening the possibility of using biotelemetry of heart rate in field situations to explore properly the full interplay of environmental factors on aerobic scope.

High river temperature reduces survival of sockeye salmon (Oncorhynchus nerka) approaching spawning grounds and exacerbates female mortality

Female and male survival differed but only when they experienced warm river temperatures, and it is suspected that females could be immuno- compromised and thus less resistant to pathogens whose rates of development are accelerated by warm temperatures.

Effects of river temperature and climate warming on stock‐specific survival of adult migrating Fraser River sockeye salmon (Oncorhynchus nerka)

Mean summer water temperatures in the Fraser River (British Columbia, Canada) have increased by ∼1.5 °C since the 1950s. In recent years, record high river temperatures during spawning migrations of

One size does not fit all: variation in thermal eco-physiology among Pacific salmonids

A more nuanced approach to west-coast salmonid conservation will be required to protect the most at-risk and vulnerable populations and incorporate population-specific traits and present and future watershed conditions.

Time to Evolve? Potential Evolutionary Responses of Fraser River Sockeye Salmon to Climate Change and Effects on Persistence

The results suggest that evolution of upriver migration timing could allow these salmon to avoid increasingly frequent stressful temperatures, with the odds of population persistence increasing in proportion to the trait heritability and phenotypic variance.

Abnormal Migration Timing and High en route Mortality of Sockeye Salmon in the Fraser River, British Columbia

Since 1995, several stocks of Fraser River sockeye salmon have begun upriver spawning migrations significantly earlier than previously observed, with high levels of en route and pre-spawning mortality, occasionally exceeding 90%.
