Landscape context affects the abundance and diversity of bees on annual crops in Europe
Résumé
(Introduction) In Europe, 80% of crop species are pollinated mostly by bees (e.g., Fig 1). Bee populations are declining worldwide (Biesmeijer et al. 2006), and this loss may alter the stability of the pollination service they provide (e.g. Chapin et al. 2001). It is therefore urgent to better understand the relationship between bee populations and biogeographic conditions. To explain the abundance and diversity of bees in agro-ecosystems, we looked at the landscape context around the fields
