the intensity of similar or dissimilar components of the energy Energy expenditure is often used as a basis of ecological theory budget of different species or of the same species in different (e.g., Gadgil and Bossert 1970; Charnov 1976; Sibly and Calow environments. From this view, field measurements of energy 1986), and its study has been a means of examining the adjustexpenditure, as interesting as they are theoretically, are the ments made by vertebrates to the environments in which they… Expand

TLDR
The clearest demonstration of the direct impact of character states is the equality of energy expenditure in species convergent with species from other clades without any evidence of the clade to which the species belong. Expand
Ecological, functional, and thermodynamic prerequisites and consequences of the origin and development of homoiothermy: A case study of avian energetics
The study is based on the results of the integrated measurement of the energy expenditure at rest and common activity in birds belonging to various systematic groups that display considerableExpand
Determinants of inter-specific variation in basal metabolic rate
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.Expand

The factors influencing the basal rate of metabolism (BMR) in 639 species of mammals include body mass, food habits, climate, habitat, substrate, a restriction to islands or highlands, use of torpor,Expand
Comparative analyses of basal rate of metabolism in mammals: data selection does matter
TLDR
A new, expanded BMR database reflecting compliance with standard criteria is provided and potential effects of differential selectivity on the results of comparative analyses are examined to indicate a need for due diligence when selecting BMR estimates and caution regarding results with small sample sizes. Expand
Seasonal Metabolic Variation in Birds: Functional and Mechanistic Correlates
TLDR
The influence of seasonal changes in temperature and climate on metabolic rates in birds has been a topic of interest to ornithologists and ecophysiologists for decades, and resting metabolic rate is considered as the metabolic rate measured under the standard conditions. Expand
Reproductive Energy Expenditure, Intraspecific Variation and Fitness in Birds
TLDR
Several studies have focused on the existence of some absolute maximum sustainable metabolic rate (MR); (2) scaling of MR and body mass; or (3) the relationship between daily energy expenditure (DEE). Expand
Flexibility in metabolic rate in a small Afrotropical bird Zosterops virens.
TLDR
Flexibility in avian basal metabolic rate seems to be linked to flexibility in the masses of certain organs and in the metabolic intensities of certain tissues, and depends primarily on body mass, but also on various environmental factors, including thermal acclimation and seasonal acclimatisation. Expand
Basal metabolic rate of birds is associated with habitat temperature and precipitation, not primary productivity
TLDR
To assess the relationship between environmental characteristics and metabolic rate in birds, collated BMR measurements for 92 populations representing 90 wild-caught species and examined the relationships between BMR and NPP, Ta, annual temperature range, precipitation and intra-annual coefficient of variation of precipitation (PCV). Expand
Allometric scaling of mammalian metabolism
TLDR
The 3/4 power scaling of RMRpp is part of a wider trend where, with the notable exception of cold-induced maximum MR, large herbivores are therefore less likely to be postabsorptive when MR is measured, and are likely to have a relatively high MR if not post absorptionptive. Expand

Measurement of Basal Metabolic Rates: Don't Lose Sight of Reality in the Quest for Comparability
TLDR
Gallivan (1992) reaches the conclusion that all previous attempts to measure BMRs of cetacea are worthless because they do not conform to the original criteria set by Kleiber for measurement of basal metabolism. Expand

Periods of Nutritional Stress in the Annual Cycles of Endotherms: Fact or Fiction?
TLDR
The main thesis of this essay is that the diversity and potency of such compensatory mechanisms haveoften been underrated, and hence the frequency and intensity of nutritional stress in free-living animals have often been exaggerated. Expand
Basal metabolic rates and thermoregulatory abilities in four small mammals
TLDR
Basal metabolism, resting metabolism, thermal neutral zone, and conductance were assessed and compared and it was concluded that S. vagrans is as good a thermoregulator as are the rodent species studied. Expand
