在不同的传粉者群落中，种间的相互作用可能会改变个体物种的行为并提高传粉效率。由于依赖授粉的农业生产正在增长，提高授粉效率可以在不增加农业强度或面积的情况下提高作物产量。在加利福尼亚杏树这种高度依赖蜜蜂授粉的作物中，我们探索了蜜蜂在单一（仅蜜蜂）和多样化（非apis蜜蜂存在）蜜蜂群落的果园中的觅食行为和授粉效果。在有非蜜蜂的果园中，蜜蜂的觅食行为发生了变化，单次蜜蜂的授粉效率高于没有非蜜蜂的果园。这一变化转化为这些果园中更大比例的果实。我们的田间实验表明，通过物种间的相互作用，传粉媒介多样性的增加可以协同增加传粉服务，从而改变显性传粉媒介物种的行为和最终的功能质量。另外，木质素木贼和蜜蜂的对照笼实验也支持了物种间功能协同作用的结果。我们的研究结果强调了生物多样性对生态系统服务的好处中一个很大程度上未被探索的促进成分，并代表了一种以可持续方式提高依赖传粉媒介的作物产量的方法。
In diverse pollinator communities, interspecific interactions may modify the behaviour and increase the pollination effectiveness of individual species. Because agricultural production reliant on pollination is growing, improving pollination effectiveness could increase crop yield without any increase in agricultural intensity or area. In California almond, a crop highly dependent on honey bee pollination, we explored the foraging behaviour and pollination effectiveness of honey bees in orchards with simple (honey bee only) and diverse (non-Apis bees present) bee communities. In orchards with non-Apis bees, the foraging behaviour of honey bees changed and the pollination effectiveness of a single honey bee visit was greater than in orchards where non-Apis bees were absent. This change translated to a greater proportion of fruit set in these orchards. Our field experiments show that increased pollinator diversity can synergistically increase pollination service, through species interactions that alter the behaviour and resulting functional quality of a dominant pollinator species. These results of functional synergy between species were supported by an additional controlled cage experiment with Osmia lignaria and Apis mellifera. Our findings highlight a largely unexplored facilitative component of the benefit of biodiversity to ecosystem services, and represent a way to improve pollinator-dependent crop yields in a sustainable manner.
