Individual differences in the energy cost of self-maintenance (resting metabolic rate, RMR)
are substantial and the focus of an emerging research area. These differences may …

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 …

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 …

An animal's relative social status has major short-and long-term consequences, yet its
determinants are rarely known. Here a strong relationship between status and standard …

" The objectives of comparative physiology are:(1) to describe the diverse ways which
different kinds of animals meet their functional requirements;(2) to elucidate evolutionary …

Publisher Summary The chapter begins with an overview of cost of living based on field
metabolic rates of small mammals. The chapter then goes on to discuss the importance of …

Abstract.—The disposable soma theory suggests that aging occurs because natural
selection favors a strategy in which fewer resources are invested in somatic maintenance …

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 …

Animal species of similar body mass vary widely in basal metabolic rate (BMR). A central
problem of evolutionary physiology concerns the anatomical/physiological origin and …
