On the Relation Between Basal and Field Metabolic Rates in Birds and Mammals
Abstract
Basal metabolic rate (BMR) is widely assumed to be an index of energy expenditure of free-living animals. However, few attempts have been made to check if the assumption is valid. In this study field metabolic rates (FMR) of 58 species of birds and mammals have been compared with their BMRs. FMR tends to increase with increasing body mass slower than BMR, but the difference was significant only in marsupials. A correlation between mass-independent FMR and BMR (residuals from regressions) is very high in eutherians (mainly rodents), but it is weak in birds and approaches zero in marsupials. The assumption of a proportionality between BMR and energy expenditure of animals does not have a sound experi-

In contrast to mammals, BMR and field metabolic rates may not be strongly correlated in birds, especially during breeding.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
