土地使用的变化威胁着全球生物多样性，并可能通过有利于某些谱系而重塑生命之树。系统发育多样性的丧失是否会损害生态系统服务的提供仍然是未知的。我们使用广泛的基因组，社区和作物数据集来研究土地利用，传粉者系统发育结构和作物生产之间的关系，以解决这一知识差距。高度农业景观中的传粉者群落的进化历史减少了2.3亿年;这种损失与作物产量和质量下降密切相关。我们的研究链接到生态系统服务的破坏，在自然群落的系统发育结构的变化介导的。仅以物种数量来衡量保护成功与否，可能无法保护生态系统的功能及其赖以生存的生命的全部多样性。
Land-use change threatens global biodiversity and may reshape the tree of life by favoring some lineages over others. Whether phylogenetic diversity loss compromises ecosystem service delivery remains unknown. We address this knowledge gap using extensive genomic, community, and crop datasets to examine relationships among land use, pollinator phylogenetic structure, and crop production. Pollinator communities in highly agricultural landscapes contain 230 million fewer years of evolutionary history; this loss was strongly associated with reduced crop yield and quality. Our study links landscape-mediated changes in the phylogenetic structure of natural communities to the disruption of ecosystem services. Measuring conservation success by species counts alone may fail to protect ecosystem functions and the full diversity of life from which they are derived.
