METABOLIC RATE AND ITS TEMPERATURE-ADAPTIVE SIGNIFICANCE IN SIX GEOGRAPHIC RACES OF PEROMYSCUS.

The metabolic rate characteristics of six races of Peromyscus, selected from a wide range of habitats, have been determined over the temperature range 0° to 35 °C. After acclimation to standardized laboratory conditions, critical temperatures and metabolic responses to temperatures below thermoneutrality were largely a function of body size: the larger the mouse, the greater its thermoregulatory efficiency. Body size per se is not correlated with the gross climate of the respective habitats. A single equation which predicts the metabolic rate of these races at any temperature between 0° and 27 °C, from a knowledge of body weight and body temperature, is derived.When considered as a single group, the basal oxygen consumption of all races varied with body weight0,60 over the body weight range of 14.7 to 36.0 g and was insignificantly different from the accepted interspecies approximation. The basal metabolic rates of each race showed no temperature-adaptive differences, especially when considered in relation to body composition. It is concluded that basal metabolic rate is nonadaptive to climate in these races of Peromyscus and consequently has played no important part in their distribution and speciation.

A simple water bath test for estimating the thermoregulation efficiency of man

A water bath test is described in which the left hand is cooled in water at 10 to 15‡C for 2 min, and the temperature then measured in the centre of the palm with a thermocouple every 15 sec. Temperature is plotted against time forming a rewarming curve. The curves for subjects suffering from diseases which may involve impaired function of the thermoregulation centre show certain features which do not occur in normal subjects. Examples are presented and the question is discussed whether the rewarming curve could serve as a test for the function of the thermoregulation centre.
