ALLOMETRIC SCALING OF TOTAL METABOLIC ENERGY PER LIFESPAN IN LIVING ORGANISMS

The purpose of the study is to establish and calculate the relationship between the total metabolic energy per lifespan and the body mass of Ectotherms, Mammals and Aves (n=278 living organisms) with 21 orders of magnitude variation between their body mass- from Bacteria to Elephas maximum and Struthio camelus. The study shows the existence of a linear relationship between the total metabolic energy per lifespan Pls (kJ), and the body mass M (kg) of all species from type: Pls=AlsM 1.0787±0.11 with R2=0.980, coefficient Als=15.18×105kJ/kg, standard error of the exponent SE=±0.11 and 95% confidence interval of the exponent (0.968 - 1.188). The same relationship for Ectotherms, Mammals and Aves without Protozoa (n=260) is of type: Pls=AlsM 1.0089±0.042 with R2=0.897, Als =14.16×105 kJ/kg, SE= ±0.042, and 95% confidence interval of exponent (0.967-1.051). In all combinations between Ectotherms, Mammals and Aves the exponent is near to 1.0. The linear coefficient Als is the total metabolic energy, exhausted during the lifespan per 1kg body mass of given organism and appears to be relatively constant parameter, because of rising 10 times only from Ectotherms to Mammals and Aves, despite of 21 orders of magnitude difference between body mass of organisms.
