This review is focused on the questions of why fish exhibit heat failure at thermal extremes
and which physiological mechanisms determine the acute upper thermal tolerance. We …

A consequence of climate change is the increased frequency and severity of extreme heat
waves. This is occurring now as most of the warmest summers and most intense heat waves …

Although it is assumed that the outcomes from scientific research inform management and
policy, the so‐called knowledge–action gap (ie, the disconnect between scientific …

Emerging diseases are impacting animals under high‐density culture, yet few studies
assess their importance to wild populations. Microparasites selected for enhanced virulence …

Global climate change is altering freshwater ecosystems and affecting fish populations and
communities. Underpinning changes in fish distribution and assemblage‐level responses to …

Warming of aquatic environments as a result of climate change is already having
measurable impacts on fishes, manifested as changes in phenology, range shifts and …

Rising river temperatures in western North America have increased the energetic costs of
migration and the risk of premature mortality in many Pacific salmon (Oncorhynchus spp.) …

In several groups of anadromous fishes, but especially the salmonids, some populations
migrate from the ocean to fresh water many months prior to spawning. This “premature …

The life cycle of diadromous fishes such as salmonids involves natural mortality in a series
of distinct life history stages, occurring sequentially in different habitats. Decades of research …

Anthropogenic climate change is warming global temperatures, with significant implications
for salmonid fishes that depend on the availability of cold water during one or more life …
