The environmental filtering of species traits can influence the identity of their interaction partners and the contribution of species interactions to ecosystem functioning, but the extent to which this process is influenced by landscape composition and configuration remains unclear. We combined a field experiment with an agent-based model to assess how landscape structure and local flower patch isolation affect pollinator body-size distribution and plant–pollinator interactions, sampled at different spatial extents. We then evaluated how these changes in pollinator functional (i.e. body-size) diversity influence plant reproduction. We observed higher pollinator functional diversity in less-isolated patches, which promoted plant reproduction via a relationship between functional diversity and interaction complementarity. This complementarity occurred partly because larger pollinators interacted with more plant species. Moreover, we showed that patch configuration at the landscape level can change the direction of these local-scale patch isolation effects on pollinator body-size distribution, functional diversity and plant–pollinator interactions. Importantly, these relationships were robust to sampling spatial extent. Thus, management strategies to promote pollination should account for local resources and landscape structure, because response, effect and interaction traits like body size connect landscape filtering effects with local community responses and outcomes of interaction-based functions.

景观结构对传粉者特征、物种相互作用和授粉成功的尺度依赖性影响

物种特征的环境过滤可以影响它们相互作用伙伴的身份以及物种相互作用对生态系统功能的贡献,但这一过程在多大程度上受景观组成和配置的影响尚不清楚。我们将田间实验与基于代理的模型相结合,以评估景观结构和局部花斑隔离如何影响传粉者体型分布和植物-传粉者相互作用,在不同的空间范围内进行采样。然后,我们评估了传粉者功能(即体型)多样性的这些变化如何影响植物繁殖。我们在不太孤立的斑块中观察到更高的传粉者功能多样性,这通过功能多样性和相互作用互补性之间的关系促进了植物繁殖。这种互补性的发生部分是因为较大的传粉者与更多的植物物种相互作用。此外,我们表明,景观层面的斑块配置可以改变这些局部规模斑块隔离效应对传粉者体型分布、功能多样性和植物-传粉者相互作用的方向。重要的是,这些关系对于采样空间范围是稳健的。因此,促进授粉的管理策略应考虑当地资源和景观结构,因为响应、效果和交互特征(如体型)将景观过滤效果与当地社区响应和基于交互的功能的结果联系起来。我们表明,景观层面的斑块配置可以改变这些局部规模斑块隔离效应对传粉者体型分布、功能多样性和植物-传粉者相互作用的方向。重要的是,这些关系对于采样空间范围是稳健的。因此,促进授粉的管理策略应考虑当地资源和景观结构,因为响应、效果和交互特征(如体型)将景观过滤效果与当地社区响应和基于交互的功能的结果联系起来。我们表明,景观层面的斑块配置可以改变这些局部规模斑块隔离效应对传粉者体型分布、功能多样性和植物-传粉者相互作用的方向。重要的是,这些关系对于采样空间范围是稳健的。因此,促进授粉的管理策略应考虑当地资源和景观结构,因为响应、效果和交互特征(如体型)将景观过滤效果与当地社区响应和基于交互的功能的结果联系起来。
