The diversity and abundance of wild insect pollinators have declined in many agricultural landscapes. Whether such declines reduce crop yields, or are mitigated by managed as honey bees, is unclear. We found universally positive associations fruit set with flower visitation insects 41 systems worldwide. In contrast, increased significantly bees only 14% the surveyed. Overall, pollinated crops more effectively; an increase enhanced twice much equivalent bee visitation. Visitation promoted...
Abstract There is compelling evidence that more diverse ecosystems deliver greater benefits to people, and these ecosystem services have become a key argument for biodiversity conservation. However, it unclear how much needed in cost-effective way. Here we show that, while the contribution of wild bees crop production significant, service delivery restricted limited subset all known bee species. Across crops, years biogeographical regions, crop-visiting communities are dominated by small...
Significance Many of the world’s crops are pollinated by insects, and bees often assumed to be most important pollinators. To our knowledge, study is first quantitative evaluation relative contribution non-bee pollinators global pollinator-dependent crops. Across 39 studies we show that insects other than efficient providing 39% visits crop flowers. A shift in perspective from a bee-only focus needed for assessments pollinator biodiversity economic value pollination. These should also...
Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related services can be maintained by a few dominant species or rely on high richness remains unclear. Using database from 89 studies (with 1475 locations), we partition the relative importance of richness, abundance, dominance for pollination; biological pest control; final yields in context ongoing land-use change. Pollinator enemy directly supported...
Abstract Managing agricultural landscapes to support biodiversity and ecosystem services is a key aim of sustainable agriculture. However, how the spatial arrangement crop fields other habitats in impacts arthropods their functions poorly known. Synthesising data from 49 studies (1515 landscapes) across Europe, we examined effects landscape composition (% habitats) configuration (edge density) on margins, pest control, pollination yields. Configuration interacted with proportions non‐crop...
The European Commission asked EFSA to revise the risk assessment for honey bees, bumble bees and solitary bees. This guidance document describes how perform from plant protection products, in accordance with Regulation (EU) 1107/2009. It is a review of EFSA's existing document, which was published 2013. outlines tiered approach exposure estimation different scenarios tiers. includes hazard characterisation provides methodology covering dietary contact exposure. also recommendations higher...
The species richness of flower-visiting insects has declined in past decades, raising concerns that the ecosystem service they provide by pollinating crops and wild plants is threatened. relative commonness different with shared ecological traits can play a pervasive role determining functioning, but information on changes abundances pollinators over time lacking. We gathered data bumble-bee Swedish red clover fields during three periods last 70 years (1940s, 1960s present), seed yields...
Summary Growing evidence for declines in wild bees calls the development and implementation of effective mitigation measures. Enhancing floral resources is a widely accepted measure promoting agricultural landscapes, but effectiveness varies considerably between landscapes regions. We hypothesize that this variation mainly driven by combination direct effects measures on local availability surrounding landscape. To test this, we established wildflower strips four European countries, using...
Abstract Mass‐flowering crops ( MFC s) are increasingly cultivated and might influence pollinator communities in fields nearby semi‐natural habitats SNH s). Across six European regions 2 years, we assessed how landscape‐scale cover of s affected densities 408 adjacent s. In fields, bumblebees, solitary bees, managed honeybees hoverflies were negatively related to the landscape. s, bumblebees declined with increasing but increased. The all pollinators generally unrelated Although apparently...
Abstract Co‐flowering plant species commonly share flower visitors, and thus have the potential to influence each other's pollination. In this study we analysed 750 quantitative plant–pollinator networks from 28 studies representing diverse biomes worldwide. We show that for one another indirectly via shared pollinators was greater plants whose resources were more abundant (higher floral unit number nectar sugar content) accessible. The indirect also stronger between phylogenetically closer...
Abstract Sustainable agriculture requires balancing crop yields with the effects of pesticides on non-target organisms, such as bees and other pollinators. Field studies demonstrated that agricultural use neonicotinoid insecticides can negatively affect wild bee species 1,2 , leading to restrictions these compounds 3 . However, besides neonicotinoids, field-based evidence landscape pesticide exposure is lacking. Bees encounter many in landscapes 4–9 this colony growth development any remains...
Widespread contamination of ecosystems with pesticides threatens non-target organisms. However, the extent to which life-history traits affect pesticide exposure and resulting risk in different landscape contexts remains poorly understood. We address this for bees across an agricultural land-use gradient based on assays pollen nectar collected by Apis mellifera, Bombus terrestris Osmia bicornis, representing extensive, intermediate limited foraging traits. found that extensive foragers (A....
Summary The recent dramatic decline in farmland biodiversity is often attributed to agricultural intensification and structural changes the landscape. One suggested farm practice seen benefit reverse declines organic farming. Because farming viewed as a more sustainable form of agriculture it currently subsidized by European agri‐environment schemes. However, efficiency schemes preserve has recently been questioned, partly because their uptake highest extensively farmed heterogeneous...
