... 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...

... capacity to produce heat is usually measured by the maximum metabolic rate in response to cold stress, often referred to as the peak metabolic rate ( Scholander et al.,1950 ; King and Farner,1961 ). However, because maximum metabolism is often elicited by protocols that feature gradually increasing cold...
