摘要
种子植物的有性生殖依赖于花粉传递,传粉者是花粉传递的媒介。传粉者为野生植物和农作物提供的传粉服务,是我们绿色星球最重要的生态过程之一,在维持生物多样性和农作物生产方面具有重要作用。农业集约化、生境破碎、全球气候变暖等因素加剧了传粉者衰减和灭绝的风险,对生态系统的功能和农业生产造成了不利影响。为了维系植物与传粉者生态互作关系的稳定性,人们建立了一系列从局部地区到国际、由普通民众到科研人员参与的传粉者监测项目,以期掌握传粉生态系统的状况和发展趋势,为自然和农业生态系统的健康提供预警和反馈。本文强调了监测传粉者的首要前提条件,即正确区分传粉者和访花者;总结了监测传粉者的直接和间接方法,包括群落水平的直接观察监测,以及利用关联数据进行间接推断与调查;介绍了具有潜力的由大众参与的公众监测项目。针对7种常见传粉者类群,讨论了可行的适用于各类群的监测方法,为监测拓展到更多的传粉者类群提供了可能。期望能为生物多样性的保护、传粉者动态的精准监测提供建议与参考。
Sexual reproduction of seed plants depends largely on pollen transfer. The pollination service provided by pollinators for wild plants and managed crops is one of the most crucial ecological processes on our planet, as it plays an essential role in sustaining biodiversity and crop production. Factors such as agricultural intensification, habitat fragmentation, and global climate change have increased the risk of pollinator decline and extinction, which would have detrimental effects on ecological function and agricultural production. To maintain the stability of ecological interactions between plants and pollinators, a series of pollinator moni- toring schemes have been established, ranging from the regional to international scale. Participants including volunteer citizens and professional scientists have obtained the status and trends of pollination systems, thereby helping to provide early alerts and feedbacks for the risk of natural and agricultural ecological systems. In this view examining the methodologies of pollinator monitoring, we emphasize that it is necessary to distinguish pollinators from floral visitors. A diversity of direct and indirect methods for monitoring pollina- tors is summarized for seven types of animals （including Lepidoptera, Coleoptera, Hymenoptera, Diptera, Aves, Mammalia, and Lacertilia, respectively）. A simple monitoring program that includes volunteer participation is also recommended. Commonly used field monitoring strategies for seven groups of pollinators would be useful as references for monitoring additional pollinator faunas. The pros and cons of these diverse methods for protecting and monitoring pollinators are discussed, which is useful for the long-term detection of pollinator dynamics.
