A new model of ectothermic growth and metabolism is proposed. This model differs from most earlier models in representing explicitly the contribution of the "cost of growth" to ectotherm metabolism. It is shown that the cost of growth may constitute between 17 and 29% of the metabolism of an "average" ectotherm population. Furthermore, the metabolism of an "average" growing ectotherm may be between 40 and 79% greater than that of a non-growing ectotherm. As many environmental factors induce changes in metabolic rates of this magnitude, it is suggested that many factors which cause changes in metabolic rates do so indirectly by altering growth rates. In particular, it is suggested that body size, food availability and temperature often indirectly influence metabolic rates through their effects on growth rates, rather than by directly determining metabolic rates as has usually been assumed.
提出了一种新的变温动物生长和代谢模型。该模型与大多数早期模型的不同之处在于，它明确表示了“生长成本”对变温动物代谢的贡献。结果表明，生长成本可能占“平均”变温动物种群代谢的17%至29%。此外，“平均”生长的变温动物的代谢可能比不生长的变温动物高40%至79%。由于许多环境因素会引起如此大幅度的代谢率变化，因此有人认为，许多导致代谢率变化的因素是通过改变生长率间接实现的。特别是，有人认为，体型、食物供应和温度通常通过对生长率的影响间接影响代谢率，而不是像通常所假设的那样直接决定代谢率。
