Complex interactions underlie the correlated evolution of floral traits and their association with pollinators in a clade with diverse pollination systems.

Natural selection by pollinators is an important factor in the morphological diversity and adaptive radiation of flowering plants. Selection by similar pollinators in unrelated plants leads to convergence in floral morphology, or “floral syndromes.” Previous investigations into floral syndromes have mostly studied relatively small and/or simple systems; emphasizing vertebrate-pollination. Despite the importance of multiple floral traits in plant-pollinator interactions, these studies have examined few quantitative traits, so their co-variation and phenotypic integration have been underexplored. To gain better insights into pollinator-trait dynamics, we investigate the model system of the phlox family (Polemoniaceae), a clade of ~ 400 species pollinated by a diversity of vectors. Using a comprehensive phylogeny and large dataset of traits and observations of pollinators, we reconstruct ancestral pollination system; accounting for the temporal history of pollinators. We conduct phylogenet...

传粉者（pollinator）介导的自然选择是显花植物形态多样性与适应性辐射的重要影响因素。亲缘关系较远的植物若受到相似传粉者的选择作用，会引发花形态的趋同演化，即所谓"花部综合征（floral syndromes）"。过往针对花部综合征的研究多聚焦于规模相对较小且/或结构较为简单的类群，且多侧重脊椎动物传粉体系。尽管花部多性状在植物-传粉者互作中具有关键作用，但此类研究仅考察了少量数量性状（quantitative trait），因此性状间的协同变异与表型整合（phenotypic integration）的相关研究仍有待深入。为更深入地解析传粉者-性状动态关系，本研究以花荵科（Polemoniaceae）为模式类群：该类群包含约400个物种，传粉媒介多样。本研究依托一套完整的系统发育（phylogeny）树，以及大规模的性状与传粉者观测数据集，重建祖先传粉系统，并纳入传粉者的演化时间历史进行考量。我们开展系统发育...
