Linking pollinator abundance in field margins to crop pollination service

Crop pollination services are an often-used argument for supporting pollinators in agricultural landscapes. However, the link between pollinator occurrence in the proximity of fields and realized crop pollination service remains poorly studied. We examined how the abundance of different pollinator taxa in field margins predicts pollination services in adjacent insect-pollinated crop in boreal agricultural landscapes. Additionally, we studied how pollinators in field margins are affected by pesticide use and landscape structure. We conducted a field experiment in 34 spring-sown turnip rape (Brassica rapa ssp. oleifera) fields and their permanent margins in Southern Finland in summer 2017. Th…
