Allometric Scaling in Biology
The design of living beings is not only a matter of molecular biology but also of geometry and physics. This was once more demonstrated with a biophysical model by G. B. West et al. (1) that had been fine-tuned to predict the famous scaling law of metabolism (2), namely a 3/4 power relation between body mass and energy consumption. While properties and predictions of the model are remarkable, a...
متن کاملAllometric scaling in-vitro
About two decades ago, West and coworkers established a model which predicts that metabolic rate follows a three quarter power relationship with the mass of an organism, based on the premise that tissues are supplied nutrients through a fractal distribution network. Quarter power scaling is widely considered a universal law of biology and it is generally accepted that were in-vitro cultures to ...

متن کاملThe perils of allometric scaling.
Dear Editor, I read with interest the paper by Chia and Aziz.1 Using allometric scaling, the authors adjusted peak oxygen uptake (VO2max) for the confounding influence of body mass and found that mass exponents differed markedly for male and female athletes. I believe the mass exponent generated for the female athletes is the suspect. In the first place, Chia regressed VO2max on body mass (Fig....
متن کاملAnalytic theories of allometric scaling.
During the 13 years since it was first advanced, the fractal network theory (FNT), an analytic theory of allometric scaling, has been subjected to a wide range of methodological, mathematical and empirical criticisms, not all of which have been answered satisfactorily. FNT presumes a two-variable power-law relationship between metabolic rate and body mass. This assumption has been widely accept...
