Determinants of intra-specific variation in basal metabolic rate
M Konarzewski, A Książek - Journal of Comparative Physiology B, 2013 - Springer
Basal metabolic rate (BMR) provides a widely accepted benchmark of metabolic
expenditure for endotherms under laboratory and natural conditions. While most studies
examining BMR have concentrated on inter-specific variation, relatively less attention has
been paid to the determinants of within-species variation. Even fewer studies have analysed
the determinants of within-species BMR variation corrected for the strong influence of body
mass by appropriate means (eg ANCOVA). Here, we review recent advancements in studies …

Determinants of inter-specific variation in basal metabolic rate
CR White, MR Kearney - Journal of Comparative physiology B, 2013 - Springer
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
thermoneutral temperature. BMR is one of the most widely measured physiological traits,
and data are available for over 1,200 species. With data available for such a wide range of
species, BMR is a benchmark measurement in ecological and evolutionary physiology, and
is often used as a reference against which other levels of metabolism are compared. Implicit …
