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 …

Adaptive explanations for both high and low body mass-independent basal metabolic rate
(BMR) in endotherms are pervasive in evolutionary physiology, but arguments implying a …

With some notable exceptions, small ectothermic vertebrates are incapable of endogenously
sustaining a body temperature substantially above ambient temperature. This view was …

on the topic that I also included within the present work. Kristian Köchy for a series of …

A major theme in evolutionary and ecological physiology of terrestrial vertebrates
encompasses the factors underlying the evolution of endothermy in birds and mammals and …

Small birds inhabiting regions with cold winter climates show seasonally flexible metabolic
phenotypes, with the winter phenotype characterized by increments of summit metabolic rate …

Survival of small birds in fluctuating environments is facilitated by seasonal metabolic and
morphological flexibility. Chinese bulbuls Pycnonotus sinensis show winter increases in …

Seasonal phenotypic flexibility in small birds produces a winter phenotype with elevated
maximum cold-induced metabolic rates (= summit metabolism, Ṁ sum). Temperature and …

The maximum intrinsic rate of population increase (r max) represents a population's
maximum capacity to replace itself and is central to fisheries management and conservation …

Metabolic rates are correlated with many aspects of ecology, but how selection on different
aspects of metabolic rates affects their mutual evolution is poorly understood. Using …
