有令人信服的证据表明，更多样化的生态系统为人类带来更大的利益，这些生态系统服务已成为生物多样性保护的一个关键论点。然而，目前尚不清楚需要多少生物多样性才能以具有成本效益的方式提供生态系统服务。在这里，我们表明，虽然野蜂对作物生产的贡献是显着的，服务提供仅限于所有已知的蜜蜂物种的有限子集。在不同作物、年份和地理区域，访问作物的野蜂群落以少数常见物种为主，在作物上很少观察到受威胁物种。占主导地位的农作物授粉持续农业扩张下，许多很容易通过简单的保护措施，这表明具有成本效益的管理策略，以促进作物授粉应针对一组不同的物种比管理策略，以促进受威胁的蜜蜂。因此，保护蜜蜂的生物多样性需要的不仅仅是基于生态系统服务的论点。 保护生物多样性的一个论点是，它提供了有益的生态系统服务。然而，Kleijn等人表明，作物授粉的经济效益仅由一小部分相对常见的物种提供，认为受威胁的物种应单独考虑。
There is compelling evidence that more diverse ecosystems deliver greater benefits to people, and these ecosystem services have become a key argument for biodiversity conservation. However, it is unclear how much biodiversity is needed to deliver ecosystem services in a cost-effective way. Here we show that, while the contribution of wild bees to crop production is significant, service delivery is restricted to a limited subset of all known bee species. Across crops, years and biogeographical regions, crop-visiting wild bee communities are dominated by a small number of common species, and threatened species are rarely observed on crops. Dominant crop pollinators persist under agricultural expansion and many are easily enhanced by simple conservation measures, suggesting that cost-effective management strategies to promote crop pollination should target a different set of species than management strategies to promote threatened bees. Conserving the biological diversity of bees therefore requires more than just ecosystem-service-based arguments. One argument for conserving biological diversity is that it delivers beneficial ecosystem services. However, Kleijn et al. show that the economic benefits of crop pollination are delivered by only a small subset of relatively common species, arguing that threatened species should be considered separately.
