We conclude that high plant diversity should ensure stable pollination services, mediated via spatio-temporal niche complementarity in flower visitation. Declining plant diversity has been shown to affect ecosystem processes such as plant-pollinator interactions, but it is currently not known if or how spatio-temporal niche partitioning of pollinators is affected by plant biodiversity. In a grassland biodiversity experiment, where we manipulated plant species richness and studied spatio-temporal resource use of pollinators, we found that complementarity of pollinator groups in space and time was stronger in species-rich mixtures.
