A Sceptics View: “Kleiber’s Law” or the “3/4 Rule” is neither a Law nor a Rule but Rather an Empirical Approximation

open access: yesSystems, 2014
Early studies showed the metabolic rate (MR) of different-sized animals was not directly related to body mass. The initial explanation of this difference, the “surface law”, was replaced by the suggestion that MR be expressed relative to massn, where the

Plasma metabolites reflect seasonally changing metabolic processes in a long-distance migrant shorebird (Calidris canutus) [PDF]

open access: yes, 2002
Migrant birds have tightly scheduled annual cycles consisting of several distinct life cycle (sub-)stages such as reproduction, migration, moult and overwintering, each of which have specific metabolic requirements (e.g., fattening during migration ...

Thyroid hormones correlate with basal metabolic rate but not field metabolic rate in a wild bird species.

open access: yesPLoS ONE, 2013
Thyroid hormones (TH) are known to stimulate in vitro oxygen consumption of tissues in mammals and birds. Hence, in many laboratory studies a positive relationship between TH concentrations and basal metabolic rate (BMR) has been demonstrated whereas ...

Basal metabolic rate in bronchial asthma and chronic obstructive pulmonary disease patients

open access: yesEgyptian Journal of Chest Disease and Tuberculosis, 2013
Patients with COPD and bronchial asthma have been reported to have an increase in the energy cost of breathing which is reflected by changes in their basal metabolic rates (BMR).
