There is increasing interest in documenting and explaining the existence of marked
intraspecific variation in metabolic rate in animals, with fishes providing some of the best …

Consistent individual differences (CIDs) in behavior are a widespread phenomenon in
animals, but the proximate reasons for them are unresolved. We discuss evidence for the …

The study of phenotypic evolution should be an integrative endeavor that combines different
approaches and crosses disciplinary and phylogenetic boundaries to consider complex …

ABSTRACT A common, long‐held belief is that metabolic rate drives the rates of various
biological, ecological and evolutionary processes. Although this metabolic pacemaker view …

Rates of aerobic metabolism vary considerably across evolutionary lineages, but little is
known about the proximate and ultimate factors that generate and maintain this variability …

It is often assumed that an animal's metabolic rate can be estimated through measuring the
whole-organism oxygen consumption rate. However, oxygen consumption alone is unlikely …

Mammals expend energy in many ways, including basic cellular maintenance and repair,
digestion, thermoregulation, locomotion, growth and reproduction. These processes can …

Metabolic rate reflects an organism's capacity for growth, maintenance and reproduction,
and is likely to be a target of selection. Physiologists have long sought to understand the …

Metabolic rates and life history strategies are both thought to set the “pace of life”, but
whether they evolve in tandem is not well understood. Here, using a common garden …

Basal metabolic rate (BMR) is the rate of metabolism of a resting, postabsorptive, non-
reproductive, adult bird or mammal, measured during the inactive circadian phase at a …
