Along with reproduction, balancing energy expenditure with the limits of resource acquisition is essential for both a species and a population to survive. But energy is a limited resource, as we know well, so birds and mammals—the most energy-inten

The ability to account with precision for the quantitative variation in the basal rate of metabolism (BMR) at the species level is explored in four groups of endotherms: arvicoline rodents, ducks, melaphagid honeyeaters, and phyllostomid bats. An eff

An earlier analysis demonstrated that the mass-independent energy expenditure of five species of the genus Peromyscus Gloger, 1841 decreased with increasing aridity along a mesic–xeric climatic gradient. Each species was represented by two populati

The recently published results from our experimental study describing the thermal flexibility of the rockwren ( Xenicus gilviventris ), combined with the unique alpine ecology of this species, led us to raise the question, as the title of our article

The thermal physiology of the endangered New Zealand rockwren (Xenicus gilviventris) is examined. It is a member of the Acanthisittidae, a family unique to New Zealand. This family, derived from Gondwana, is thought to be the sister taxon to all othe

Brain mass has been suggested to determine a mammal's energy expenditure. This potential dependence is examined in 48 species of bats. A correlation between characters may be direct or derived from shared correlations with intervening factors without

The basal rate of metabolism (BMR) is the most reported estimate of energy expenditure in endotherms. Its principal determinant is body mass, but it also correlates with a variety of behavioral not determine basal rate, they are byproducts of the mec

The energy expenditure of the tūī (Prosthemadera novaeseelandiae), a meliphagid endemic to New Zealand, was measured and compared with 20 species of honeyeaters (family Meliphagidae) to determine whether its expenditure is influenced either by life
