Abstract:
|
Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to
food production. Whether crop yield–related ecosystem services can be maintained by a few dominant
species or rely on high richness remains unclear. Using a global database from 89 studies (with 1475 locations), we partition the relative importance of species richness, abundance, and dominance for pollination;
biological pest control; and final yields in the context of ongoing land-use change. Pollinator and enemy
richness directly supported ecosystem services in addition to and independent of abundance and dominance. Up to 50% of the negative effects of landscape simplification on ecosystem services was due to
richness losses of service-providing organisms, with negative consequences for crop yields. Maintaining
the biodiversity of ecosystem service providers is therefore vital to sustain the flow of key agroecosystem
benefits to society. |
