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 …

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 …

Explaining variation in the fitness of organisms is a fundamental goal in evolutionary
ecology. Maintenance energy metabolism is the minimum energy required to sustain …

How does an animal age in natural conditions? Given the multifaceted nature of
senescence, identifying the effects of age on physiology and behavior remains challenging …

Metabolic rates can vary as much as threefold among individuals of the same size and age
in a population, but why such variation persists is unclear given that they determine the …

Metabolic cold adaptation (MCA), the hypothesis that species from cold climates have
relatively higher metabolic rates than those from warm climates, was first proposed nearly …

The form of the relationship between the basal metabolic rate (BMR) and body mass (M) of
mammals has been at issue for almost seven decades, with debate focusing on the value of …

Metabolic cold adaptation, or Krogh's rule, is the controversial hypothesis that predicts a
monotonically negative relationship between metabolic rate and environmental temperature …

Variation in aerobic capacity has far reaching consequences for the physiology, ecology,
and evolution of vertebrates. Whether at rest or active, animals are constrained to operate …
