生态恢复植物种源的选择是一个备受争议的话题。在这场争论中，争论主要集中在植物的表现上，而很少关注种源对恢复生态系统其他成员的影响。另一方面，在专门侧重于支持相互作用的生物群的恢复项目中，例如，在田间种植野花以支持传粉者，往往不考虑种源的选择，部分原因是种源对传粉者的影响是未知的。在这个开创性的案例研究中，我们测试了传粉者是否区分不同种源的实验植物群落。我们建立了具有相同物种组成但来自三个不同种源的植物的实验植物群落。然后，我们记录植物物候和观察传粉者和花访客与这些实验社区和相关的传粉者访问的种源identity.The种源的实验植物群落的花传粉者相互作用的多样性和丰富度有很强的和显着的影响，与一个种源的相互作用的两倍，其他两个种源。这种效应是由种源间开花物候的差异驱动的。植物种源在与当地传粉者的相互作用方面存在很大差异。因此，植物种源的选择，应考虑在规划恢复项目，以支持传粉者。
The selection of plant provenance for ecological restoration is an intensively debated topic. Throughout this debate, arguments mostly focus on plant performance, but little attention is paid to the effects of provenance on other members of the restored ecosystem. On the other hand, in restoration projects that focus specifically on supporting interacting biota, for example, wildflower strips among fields to support pollinators, the provenance choice is often not considered, partly because the effect of provenance on pollinators is unknown. In this pioneering case study, we tested whether pollinators differentiate between experimental plant communities of different provenances.We established experimental plant communities with the same species composition but with plants originating from three different provenances. We then recorded plant phenology and observed pollinators and flower visitors interacting with these experimental communities and related the pollinator visitation to the provenance identity.The provenances of the experimental plant communities had a strong and significant effect on the diversity and abundance of flower-pollinator interactions, with one provenance interacting two times as often as the other two provenances. The effect was driven by the differences in flowering phenology among provenances.Synthesis and applications. Plant provenances substantially differ in their interactions with local pollinators. Therefore, the selection of plant provenance should be considered when planning restoration projects for the support of pollinators.
