物种相互作用受到当地多营养群落特征结构的影响。然而,目前尚不清楚互利相互作用是否能够在全球范围内驱动性状模式,其中气候限制和生物地理过程变得越来越重要。在这里,我们评估了食果鸟类和棕榈树(槟榔科)性状之间的全球关系,以及这些关系如何直接或间接地受到组合丰富度、气候和生物地理历史的影响。我们利用几乎所有鸟类食果动物的新的和扩展的张口大小数据集,并发现张口大小和果实大小之间的正相关关系,即性状匹配,它间接受到棕榈丰富度和气候的影响。我们还发现了性状匹配强度的纬度梯度,该梯度向热带地区增加,并且在动物地理领域之间有所不同。综上所述,我们的结果表明,营养相互作用对性状结构具有一致的影响,但非生物、生物地理和丰富度效应在塑造互利共生的功能生物地理学方面也发挥着重要的作用,尽管有时是间接的。
Species interactions are influenced by the trait structure of local multi-trophic communities. However, it remains unclear whether mutualistic interactions in particular can drive trait patterns at the global scale, where climatic constraints and biogeographic processes gain importance. Here we evaluate global relationships between traits of frugivorous birds and palms (Arecaceae), and how these relationships are affected, directly or indirectly, by assemblage richness, climate and biogeographic history. We leverage a new and expanded gape size dataset for nearly all avian frugivores, and find a positive relationship between gape size and fruit size, i.e., trait matching, which is influenced indirectly by palm richness and climate. We also uncover a latitudinal gradient in trait matching strength, which increases towards the tropics and varies among zoogeographic realms. Taken together, our results suggest trophic interactions have consistent influences on trait structure, but that abiotic, biogeographic and richness effects also play important, though sometimes indirect, roles in shaping the functional biogeography of mutualisms.
