ABSTRACT Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related services can be maintained by few abundant species or rely on high richness remains unclear. Using a database from 89 systems, we partition the relative importance of abundance for pollination, biological pest control final yields in context on-going land-use change. Pollinator enemy directly supported independent abundance. Up 50% negative effects landscape simplification was due losses service-providing organisms, with consequences yields. Maintaining service providers is therefore vital sustain flow key agroecosystem benefits society.
