Environmental variability in aquatic ecosystems makes the study of ectotherms complex and
challenging. Physiologists have historically overcome this hurdle in the laboratory by using …

Freshwater fish face a variety of spatiotemporal thermal challenges throughout their life. On
a broad scale, temperature is an important driver of physiological, behavioural and …

The frequency of extreme thermal events in temperate freshwater systems is expected to
increase alongside global surface temperature. The Miramichi River, located in eastern …

Long-term temperature shifts associated with seasonal variability are common in temperate
regions. However, these natural shifts could place significant strain on thermal stress …

The temperature of the rivers in the Qilian Mountains, China varies widely from day to night,
and Gymnocypris chilianensis living in these rivers may experience a change of 10° C to 20° …

The role of temperature on biological activities and the correspondent exponential
relationship with temperature has been known for over a century. However, lacking to date is …

Many fish naturally encounter a daily cycle of hypoxia, but it is unclear whether this exposure
hardens hypoxia-intolerant fish to future hypoxia or leads to accumulated stress and death …

Higher water temperatures and pathogens are both significant factors that negatively affect
the welfare of teleost fish. In aquaculture, compared to natural populations, these problems …

Atlantic salmon populations are declining, and warming river temperatures in the summer
months are thought to be a significant contributing factor. We describe the time course of …

Although most animals live in complex, thermally variable environments, the impact of this
variability on specific physiological systems is still unresolved. The ectotherm heart is known …
