众所周知，动物窝建筑的特点可以用安置在里面的后代获得的健康益处来解释。在这里，我们把重点放在一个很少被检验的建议上，即与建造和维护鸟巢相关的健康成本应该额外考虑到它的架构的各个方面。埋葬甲虫从一具小的脊椎动物身体上为它们的幼崽准备一个可食用的巢，方法是撕下任何毛皮或羽毛，并将肉卷成一个圆形的球。我们发现有证据表明，只有较大的甲虫才能建造圆形的身体巢，而且圆形的身体巢与较低的维护成本有关。然而，后代的成功并不能用巢的圆度来解释。因此，我们的实验罕见地支持了建造和维护成本是理解动物建筑的关键这一观点。
It is well-known that features of animal nest architecture can be explained by fitness benefits gained by the offspring housed within. Here we focus on the little-tested suggestion that the fitness costs associated with building and maintaining a nest should additionally account for aspects of its architecture. Burying beetles prepare an edible nest for their young from a small vertebrate carcass, by ripping off any fur or feathers and rolling the flesh into a rounded ball. We found evidence that only larger beetles are able to construct rounder carcass nests, and that rounder carcass nests are associated with lower maintenance costs. Offspring success, however, was not explained by nest roundness. Our experiment thus provides rare support for the suggestion that construction and maintenance costs are key to understanding animal architecture.
