行为的进化既能影响形态,也能受形态的影响。方法和数据可用性的最新进展促进了在许多情况下对物理形态和行为功能的大规模研究,但动物形态和物体操纵(特别是建筑中使用的物体)之间的关系仍然很大程度上未知。在这里,我们采用了 5924 种鸟类使用的新的筑巢材料全球数据库以及系统发育随机森林模型来评估喙形状与这些筑巢材料之间的联系。我们发现喙的形态,加上物种的饮食和材料的获取,可以预测巢穴材料的使用,并且准确率很高(68-97%)。然而,这种关系很大程度上是由系统发育信号和抽样偏差驱动的。因此,我们得出的结论是,虽然巢穴材料使用的变化与不同鸟类的喙形状有关,但这些相关性受到这些物种的生态环境和进化历史的调节。本文是主题“巢的进化生态学:跨分类方法”的一部分。
The evolution of behaviour can both influence, and be influenced by, morphology. Recent advances in methods and data availability have facilitated broad-scale investigations of physical form and behavioural function in many contexts, but the relationship between animal morphology and object manipulation—particularly objects used in construction—remains largely unknown. Here, we employ a new global database of nest materials used by 5924 species of birds together with phylogenetically informed random forest models to evaluate the link between beak shape and these nest-building materials. We find that beak morphology, together with species diet and access to materials, can predict nest-material use above chance and with high accuracy (68–97%). Much of this relationship, however, is driven by phylogenetic signal and sampling biases. We therefore conclude that while variation in nest material use is linked with that of beak shape across bird species, these correlations are modulated by the ecological context and evolutionary history of these species. This article is part of the theme issue ‘The evolutionary ecology of nests: a cross-taxon approach’.
