Energy metabolism (encompassing energy assimilation, conversion and utilization) plays a
central role in all life processes and serves as a link between the organismal physiology …

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

Temperature is a critical abiotic factor sha** the distribution and abundance of species,
but the mechanisms that underpin organismal thermal limits remain poorly understood. One …

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 …

Increasing temperatures under climate change are thought to affect individual physiology of
fish and other ectotherms through increases in metabolic demands, leading to changes in …

The physiological causes of intraspecific differences in fitness components such as growth
rate are currently a source of debate. It has been suggested that differences in energy …

Mitochondrial performance may play a role in setting whole-animal thermal tolerance limits
and their plasticity, but the relative roles of adjustments in mitochondrial performance across …

Many animals experience periods of food shortage in their natural environment. It has been
hypothesised that the metabolic responses of animals to naturally‐occurring periods of food …

Standard metabolic rate (SMR) and maximum metabolic rate (MMR) typically vary two-or
threefold among conspecifics, with both traits assumed to significantly impact fitness …

Mitochondrial metabolism varies significantly between individuals of the same species and
can influence animal performance, such as growth. However, growth rate is usually …
