It was tested whether isolation from florally diverse natural and semi-natural areas reduces the spatial and temporal stability of flower-visitor richness and pollination services in crop fields.

Bees provide essential pollination services that are potentially affected both by local farm management and the surrounding landscape. To better understand these different factors, they modelled the relative effects of landscape composition , landscape configuration and farm management, and their interactions, on wild bee abundance and richness for 39 crop systems globally.
