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...
Significance Growing concern about bee declines and associated loss of pollination services has increased the urgency to identify underlying causes. So far, identification key drivers decline populations largely been based on speculation. We assessed relative importance a range proposed factors responsible for wild show that preferred host plant species is one main with in The Netherlands. Interestingly, foraging crop families have stable or increasing populations. These results indicate...
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...
Declines in insect pollinators across Europe have raised concerns about the supply of pollination services to agriculture. Simultaneously, EU agricultural and biofuel policies encouraged substantial growth cultivated area pollinated crops continent. Using data from 41 European countries, this study demonstrates that recommended number honeybees required provide crop has risen 4.9 times as fast honeybee stocks between 2005 2010. Consequently, were insufficient >90% demands 22 countries...
Abstract Agricultural intensification and associated loss of high‐quality habitats are key drivers insect pollinator declines. With the aim decreasing environmental impact agriculture, 2014 EU Common Policy (CAP) defined a set habitat landscape features (Ecological Focus Areas: EFAs) farmers could select from as requirement to receive basic farm payments. To inform post‐2020 CAP, we performed European‐scale evaluation determine how different EFA options vary in their potential support...
Abstract The sustainability of agriculture can be improved by integrating management ecosystem services, such as insect pollination, into farming practices. However, large‐scale adoption services‐based practices in is lacking, possibly because growers undervalue the benefits services compared to those conventional Here we show that, under representative real‐world conditions, pollination and plant quality made similar contributions marketable seed yield hybrid leek ( Allium porrum )....
Agricultural expansion and intensification have boosted global food production but come at the cost of environmental degradation biodiversity loss. Biodiversity-friendly farming that boosts ecosystem services, such as pollination natural pest control, is widely being advocated to maintain improve agricultural productivity while safeguarding biodiversity. A vast body evidence showing agronomic benefits enhanced service delivery represent important incentives adopt practices enhancing However,...
ABSTRACT Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related services can be maintained by few abundant species or rely on high richness remains unclear. Using a database from 89 systems, we partition the relative importance of abundance for pollination, biological pest control final yields in context on-going land-use change. Pollinator enemy directly supported independent abundance. Up 50%...
Land-use change and global warming are important factors driving bee decline, but it is largely unknown whether these drivers have resulted in changes the life-history traits of bees. Recent studies shown a stronger population decline large- than small-bodied species, suggesting there may been selective pressure on large, not small species to become smaller. Here we test this hypothesis by analyzing trends body size 18 Dutch over 147-year period using specimens from entomological...
Abstract Pollination by insects is a key input into many crops, with managed honeybees often being hired to support pollination services. Despite substantial research management, no European studies have yet explored how and why farmers services few beekeepers use certain crops. Using paired surveys of in 10 countries, this study examines beekeeper farmer perceptions motivations surrounding crop pollination. Almost half the surveyed believed they had service deficits one or more their Less...
Abstract The decline of managed honeybees and the rapid expansion mass‐flowering crops increase risk pollination limitation in raise questions about novel management approaches for wild pollinators agroecosystems. Adding artificial nesting sites, such as trap nests, can promote cavity‐nesting bees agroecosystems, but effectiveness could be limited by availability floral resources surrounding landscape natural antagonists. In two European regions, we exposed nests paired field boundaries...
Conserving and restoring semi-natural habitat, i.e. enhancing landscape complexity, is one of the main strategies to mitigate pollinator decline in agricultural landscapes. However, we still have limited understanding how complexity shapes communities both crop non-crop whether responses vary with their association mass-flowering crops. Here, surveyed on leek crops nearby habitat landscapes varying complexity. Surveys were done before during bloom distinguished between pollinators that visit...
Wildflower strips have been heralded as a promising way to enhance ecosystem services by providing organisms which may help make farming less dependent on external inputs. However, recent studies show inconsistent effects delivery of and crop yield, warranting more detailed analysis the factors determining wildflower strips. We examined how natural enemy groups spider, carabid beetle staphylinid beetle, well aphid pest yield respond furthermore determined whether response enemies, aphids...
Abstract Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we limited our capacity to understand variation benefits yield, as well anticipate changes service, develop predictions, and inform management actions. Here, present CropPol, a dynamic, open, database It contains measurements...
Agricultural intensification has resulted in a decline insect biodiversity and threatens the provision of valuable ecosystem services. Agri-environment schemes (AESs) have been implemented an effort to conserve on farmland increase agricultural sustainability, but their effectiveness can vary widely. To better determine which factors influence AES effectiveness, relative roles local habitat features, quality, landscape context need be further explored. The aim this study was most important...
Reconciling biodiversity conservation with agricultural production requires a better understanding of how key ecosystem service providing species respond to intensification. Carabid beetles and spiders represent two widespread guilds biocontrol services. Here we surveyed carabid in 66 winter wheat fields four northwestern European countries analyzed the activity density diversity were related crop yield (proxy for land-use intensity), percentage cropland landscape complexity) soil organic...
