By facilitating plant reproduction, pollinators perform a crucial ecological function that supports the majority of the world's plant diversity, and associated organisms, and a significant fraction of global agriculture. Thus, pollinators are simultaneously vital to supporting both natural ecosystems and human food security, which is a unique position for such a diverse group of organisms. The past two decades have seen unprecedented interest in pollinators and pollination ecology, stimulated in part by concerns about the decline of pollinator abundance and diversity in some parts of the world. This review synthesizes what is currently understood about the taxonomic diversity of organisms that are known to act as pollinators; their distribution in both deep time and present space; the importance of their diversity for ecological function (including agro-ecology); changes to diversity and abundance over more recent timescales, including introduction of non-native species; and a discussion of arguments for ...

传粉媒介多样性：分布、生态功能和保护

通过促进植物繁殖，传粉媒介发挥着重要的生态功能，支持世界上大部分植物多样性和相关生物，以及全球农业的重要组成部分。因此，传粉媒介对支持自然生态系统和人类粮食安全同时至关重要，这对于如此多样化的生物群来说是一个独特的位置。过去二十年来，人们对传粉媒介和传粉生态学产生了前所未有的兴趣，部分原因是对世界某些地区传粉媒介丰度和多样性下降的担忧。这篇综述综合了目前对已知充当传粉媒介的生物的分类多样性的了解；它们在深层时间和现在空间中的分布；它们的多样性对生态功能（包括农业生态）的重要性；最近时间尺度上多样性和丰度的变化，包括引入非本地物种；以及对……的论据的讨论
