Basal rate of metabolism (BMR) is a physiological parameter that should be measured under strictly defined experimental conditions. In comparative analyses among mammals BMR is widely used as an index of the intensity of the metabolic machinery or as a proxy for energy expenditure. Many databases with BMR values for mammals are available, but the criteria used to select metabolic data as BMR estimates have often varied and the potential effect of this variability has rarely been questioned.

Coevolution of body size and metabolic rate in vertebrates: a life‐history perspective
TLDR
It is argued that scaling exponents of these allometries do not themselves mirror one universal law of nature but instead statistically approximate the non‐linearity of the relationship between MR and body mass, and that an explanation based on the theory of life‐history evolution is the best way forward. Expand
Energetic constraints on mammalian home‐range size
TLDR
The first quantitative support for the hypothesis that home‐range size is limited by metabolic rates, accounting for variation in body mass, is presented and suggests optimization of energy allocation where past selection promoted an increase in mobility at the lowest possible body maintenance costs.

Phylogenetic analysis of maximal oxygen consumption during exercise (V̇O2,max) and ecological correlates among lizard species
TLDR
Among species of lizards, helodermatids, varanids and skinks (which are mainly active foragers) have relatively high maximal aerobic capacity during forced exercise, whereas viviparous species have relatively low V̇O2,max. Expand
Assigning metabolic rate measurements to torpor and euthermia in heterothermic endotherms: “torpor”, a new package for R
TLDR
A novel method for distinguishing torpor from euthermia is proposed and the variation in M measured during euthermic rest and torpor at different ambient temperatures (Ta) is used to estimate the lower critical temperature of the thermoneutral zone (TNZ) and determine physiological state membership using a mixture model.

Allomaternal care, brains and fertility in mammals: who cares matters
TLDR
Using a sample of 478 mammals, it is shown that paternal care, which is both reliable and stable, shows correlated evolution with brain size, whereas alloparental Care, which fluctuates with varying availability of helpers, is correlated with higher fertility. Expand
Using Integrative Biology to Infer Adaptation from Comparisons of Two (or a Few) Species
TLDR
It is proposed that the philosophical principle of severity can be implemented in an integrative framework to generate strong inference of adaptation in studies that compare only a few populations or species. Expand
Animal life history is shaped by the pace of life and the distribution of age-specific mortality and reproduction
TLDR
Analysis of demographic data from 121 species shows that animal life history strategies vary across two axes of variation defined by the pace of life and the distribution of a species’ mortality and reproduction over their life course. Expand
Inter- and intra-specific variation in hair cortisol concentrations of Neotropical bats
TLDR
It is found that fecundity is an important ecological trait explaining interspecific variation in bat hair cortisol, and other ecological variables such as colony size, roost durability, and basal metabolic rate did not explain hair cortisol variation among species. Expand
Small Tropical Mammals Can Take the Heat: High Upper Limits of Thermoneutrality in a Bornean Treeshrew
TLDR
The research highlights the knowledge gaps in understanding of the energetics of mammals living in high-temperature environments, and questions the purported lack of variance in the upper critical temperatures of the thermoneutral zone in mammals, emphasizing the importance of further research in the tropics. Expand
Inter- and intra-specific variation in hair cortisol concentrations of Neotropical bats
TLDR
It is found that fecundity is an important ecological trait explaining inter-specific variation in bat hair cortisol, and other ecological variables such as colony size, roost durability and basal metabolic rate did not explain hair cortisol variation among species. Expand

The Functional Significance of Individual Variation in Basal Metabolic Rate
TLDR
By comparing groups of individuals, for example, lactating and nonlactating individuals, the patterns that emerge are broadly consistent with the hypothesis that BMR and SusMR are linked by morphology, with very little support for the suggestion that variation in RMRt (and thus BMR) is sustained by associations with SusMR.

The Allometry of Avian Basal Metabolic Rate: Good Predictions Need Good Data
TLDR
The analyses using a data set that included only BMR with n ≥ 3 were consistent with the conclusion that BMR does not differ between passerine and nonpasserine birds after taking phylogeny into account. Expand
Does Basal Metabolic Rate Contain a Useful Signal? Mammalian BMR Allometry and Correlations with a Selection of Physiological, Ecological, and Life‐History Variables
TLDR
Data from 619 species show that if variation associated with body temperature and digestive state are removed, the BMRs of eutherians, marsupials, and birds do not differ, and no significant allometric exponent heterogeneity remains between orders. Expand
Complications Inherent in Scaling the Basal Rate of Metabolism in Mammals
  • B. McNab
  • Biology, Medicine
  • The Quarterly Review of Biology

TLDR
The scaling of the basal rate of metabolism in mammals is reexamined and suggests that insight into the significance of scaling relations can be obtained by examining the residual variation around a scaling function as well as by examining conformation to the function. Expand
Basal Metabolic Rate: History, Composition, Regulation, and Usefulness
TLDR
It is suggested that in different‐sized mammals, the secretion/production of thyroid hormones is a result of BMR differences rather than their cause, and BMR is a useful concept in some situations but not in others. Expand
Determinants of intra-specific variation in basal metabolic rate
TLDR
It is concluded that within-species variation in BMR and its components have a clear genetic signature, and are functionally linked to key metabolic process at all levels of biological organization and the need to integrate molecular genetics with conventional metabolic field studies to reveal the adaptive significance of metabolic variation is highlighted.
