...% and was unrelated to temperature, body mass, sex or ration size. Our findings suggest that sex has a negligible role in shaping SDA, nor is SDA a contributor to SSD for this species. Standard and maximum metabolic rates were similar between sexes but maximum metabolic rate decreased drastically with body mass...

... and this is the critical P O 2 for the maximum metabolic rate, P crit-max . For most terrestrial and shallow-living marine species, P crit-max is the current atmospheric pressure, 21 kPa. Any reduction in oxygen partial pressure from current values will result in a calculable decrement in maximum metabolic performance...

... in ecophysiology and conservation physiology studies; however, few studies have tested whether they yield comparable results. We examined whether two fundamental measures, standard metabolic rate (SMR) and maximum metabolic rate (MMR), vary based on the method employed. Ten bridled monocle bream ( Scolopsis...

Maximum metabolic rate of locusts during tethered flight ( Ṁ m O 2 ; μmol O 2 h −1 ) increased with body mass ( M b ; g) according to the allometric equation Ṁ m O 2 =994 M b...

This allometric study investigates the effect of body mass ( M b ) on oxygen consumption rate ( , μmol h –1 ) to establish resting metabolic rate ( ), maximum metabolic rate during hopping ( ) and maximum...

As explained above, T b decreases during the DU trials even before chicks reach their maximum metabolic rate. This failure to regulate T b might derive from the lag between the sensation...

We measured these variables in Phyllotis darwini , a murid rodent from central Chile, under conditions of warm and cold acclimation. In addition to standard statistical...

...Roberto F. Nespolo; Leonardo D. Bacigalupe; Pablo Sabat; Francisco Bozinovic SUMMARY The potential for thermal acclimation in marsupials is controversial. Initial studies suggest that the thermoregulatory maximum metabolic rate (MMR)in metatherians cannot be changed by thermal acclimation...
