Supporting ecosystem services and conserving biodiversity may be compatible goals, but there is concern that service-focused interventions mostly benefit a few common species. We use a spatially replicated, multiyear experiment in four agricultural settings to test if enhancing habitat adjacent to crops increases wild bee diversity and abundance on and off crops. We found that enhanced field edges harbored more taxonomically and functionally abundant, diverse, and compositionally different bee communities compared to control edges. Enhancements did not increase the abundance or diversity of bees visiting crops, indicating that the supply of pollination services was unchanged following enhancement. We find that actions to promote crop pollination improve multiple dimensions of biodiversity, underscoring their conservation value, but these benefits may not be spilling over to crops. More work is needed to identify the conditions that promote effective co-management of biodiversity and ecosystem services.

生物多样性和生态系统服务的结果不匹配：测试作物授粉媒介和野生蜂生物多样性对生境增强的反应。

支持生态系统服务和保护生物多样性可能是兼容的目标，但人们关注的是，以服务为中心的干预措施大多会使一些常见物种受益。我们在四个农业环境中使用了一项空间复制的多年期实验，以测试与作物相邻的栖息地的增强是否会增加野生蜂的多样性以及作物内外的丰富度。我们发现，与对照边缘相比，增强的田间边缘在分类学和功能上具有更多的蜂群，多样性和组成上不同的蜜蜂群落。改良并没有增加参观农作物的蜜蜂的丰度或多样性，这表明强化后授粉服务的供应没有变化。我们发现，促进作物授粉的行动改善了生物多样性的各个方面，强调了其保护价值，但是这些好处可能不会溢出到农作物上。需要开展更多工作来确定促进有效地共同管理生物多样性和生态系统服务的条件。
