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 …

Observations of climate impacts on ecosystems highlight the need for an understanding of
organismal thermal ranges and their implications at the ecosystem level. Where changes in …

Because of its profound effects on the rates of biological processes such as aerobic
metabolism, environmental temperature plays an important role in sha** the distribution …

Environmental signals act primarily on physiological systems, which then influence higher‐
level functions such as movement patterns and population dynamics. Increases in average …

Maximum (aerobic) metabolic rate (MMR) is defined here as the maximum rate of oxygen
consumption (O2max) that a fish can achieve at a given temperature under any ecologically …

The Commentary by Pörtner, Bock and Mark (Pörtner et al., 2017) elaborates on the oxygen-
and capacity-limited thermal tolerance (OCLTT) hypothesis. Journal of Experimental Biology …

Identifying factors that influence how ectothermic animals respond physiologically to
changing temperatures is of high importance given current threats of global climate change …

The problem of understanding the effect of the environment on fish activities and
performance, in any generalized way, remains intractable. Solving this issue is, however, a …

Intraspecific variation in key traits such as tolerance of warming can have profound effects
on ecological and evolutionary processes, notably responses to climate change. The …

With the occurrence of global change, research aimed at estimating the performance of
marine ectotherms in a warmer and acidified future has intensified. The concept of oxygen …
