Document Summary
Body size and allometry the scaling of organismal structure and function. If you know the body size of an animal can predict other aspects (breathing rate with 95% accuracy, aging with ~60% accuracy) Allometry: study of the relationship between size and shape: scales linearly: isometric, allometric: doesn"t scale linearly (different) Scaling of respiration rate, enzyme concentrations in cells. Samaras thomas t. : human body size and the laws of scaling: physiological performance, growth, longevity and ecological ramifications. Nova publishers: taller humans tend to have shorter lifespans, basketball players who are very tall are prone to heart attacks. Competition for the smallest vertebrate bumblebee bat weighs only 2g in size: lower limit for an endothermic mammal/bird, about the size of the largest insect. Etruscan shrew weighs about the same amount but the tail causes it to exceed the bat. Ranges up to the blue whale 136 mil g.
