哺乳动物和鸟类最大和基础代谢率的标度
The Scaling of Maximum and Basal Metabolic Rates of Mammals and Birds
摘要：
异速生长是生物学中最普遍的定律之一。然而，它的起源仍然是一个有争议的问题。最近的研究表明，最大代谢率的指数大于基础代谢率。这个不可预测的结果提出了一个挑战，可以决定哪个并发假设是正确的理论。在这里，我们表明，这两个标度律可以推导出一个单一的网络模型。除了基础代谢的3/4定律外，该模型还预测最大代谢率为$M^{6/7}$，最大心率为$M^{-1/7}$，肌肉毛细血管密度为$M^{-1/7}$，与数据一致。
英文摘要：
Allometric scaling is one of the most pervasive laws in biology. Its origin, however, is still a matter of dispute. Recent studies have established that maximum metabolic rate scales with an exponent larger than that found for basal metabolism. This unpredicted result sets a challenge that can decide which of the concurrent hypotheses is the correct theory. Here we show that both scaling laws can be deduced from a single network model. Besides the 3/4-law for basal metabolism, the model predicts that maximum metabolic rate scales as $M^{6/7}$, maximum heart rate as $M^{-1/7}$, and muscular capillary density as $M^{-1/7}$, in agreement with data.
