大约 20 个生理变量的大小依赖性是从一个相当简单的能量预算模型中得出的。这个九参数模型基于对不同食物密度下生长和繁殖的详细观察，并具有状态变量大小和存储。对于同一物种的动物和不同物种的动物来说，某些变量的大小依赖性是不同的。例如，同一物种的动物的繁殖率往往会随着体型的增大而增加，但不同物种的动物的繁殖率会随着体型的增大而降低。这是因为参数值在一个物种内是常数，但对于不同物种的动物来说，其大小依赖于大小。尽管假定食物密度恒定的生长属于 von Bertalanffy 类型，并且常规代谢与体型成正比，但事实证明，无论是在物种内部还是在物种之间，呼吸作用都与体型的 3/4 次方成正比。经常发现大约 3/4 的值，但它一直被认为与 von Bertalanffy 增长不相容。
The size-dependence of some 20 physiological variables has been derived from a rather simple model for energy budgets. This nine parameter model is based on detailed observations on the growth and reproduction at varying food densities, and has the state variables size and storage. The size-dependence of some variables works out to be different for animals of the same species as opposed to animals of different species. The reproductive rate, for instance, tends to increase with size for animals of the same species, but to decrease with size for animals of different species. This is because the parameter values are constants within a species, but vary in a size dependent manner for animals of different species. Although growth at constant food density is assumed to be of the von Bertalanffy type, and routine metabolism to be proportional to size, respiration turns out to be about proportional to size to the power 3/4, both within and between species. The value of about 3/4 has frequently been found, but it has always been thought to be incompatible with von Bertalanffy growth.
