身体大小和形状在生物体功能中起着重要作用，预计动物可能拥有适合其生态位的身体比例。四足动物的身体形状多种多样，但迄今为止，这种身体比例的多样性及其与生态的关系尚未被系统地量化。使用全身骨骼模型的410个灭绝和现存的四足动物，我们表明，异速生长的关系在各个身体部位不同，从而产生的变化，整体体型的大小增加。然而，我们也发现统计支持二次关系，表明在中小型与大型动物的差异缩放。运动和饮食组的比较突出了身体比例的关键差异，这可能是占据主要生态位的机械基础。我们的研究结果强调了身体比例在四足动物大规模生态多样性中的关键作用。在这里，作者研究了410个四足动物模型的身体大小，形状和部分比例与生态学的关系。他们发现变量异速生长关系，在小型和大型动物的差异缩放，和身体比例作为一个潜在的生态位占用机制。
Body size and shape play fundamental roles in organismal function and it is expected that animals may possess body proportions that are well-suited to their ecological niche. Tetrapods exhibit a diverse array of body shapes, but to date this diversity in body proportions and its relationship to ecology have not been systematically quantified. Using whole-body skeletal models of 410 extinct and extant tetrapods, we show that allometric relationships vary across individual body segments thereby yielding changes in overall body shape as size increases. However, we also find statistical support for quadratic relationships indicative of differential scaling in small-medium versus large animals. Comparisons of locomotor and dietary groups highlight key differences in body proportions that may mechanistically underlie occupation of major ecological niches. Our results emphasise the pivotal role of body proportions in the broad-scale ecological diversity of tetrapods. Here, the authors examine how body size, shape, and segment proportions correspond to ecology in models of 410 tetrapods. They find variable allometric relationships, differential scaling in small and large animals, and body proportions as a potential niche occupation mechanism.
