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...
Sustainable agricultural landscapes by definition provide high magnitude and stability of ecosystem services, biodiversity, crop productivity.However, few studies have considered landscape effects on the services.We tested whether isolation from florally diverse natural semi-natural areas reduces spatial temporal flower-visitor richness pollination services in fields.We synthesized data 29 with contrasting biomes, species, pollinator communities.Stability richness, visitation rate (all...
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...
Intensification or abandonment of agricultural land use has led to a severe decline semi-natural habitats across Europe. This can cause immediate loss species but also time-delayed extinctions, known as the extinction debt. In pan-European study 147 fragmented grassland remnants, we found differences in debt from different trophic levels. Present-day richness long-lived vascular plant specialists was better explained by past than current landscape patterns, indicating an contrast,...
Bee pollinators are currently recorded with many different sampling methods. However, the relative performances of these methods have not been systematically evaluated and compared. In response to strong need record ongoing shifts in pollinator diversity abundance, global regional initiatives must adopt standardized protocols when developing large‐scale long‐term monitoring schemes. We performance six (observation plots, pan traps, variable transect walks, trap nests reed internodes or paper...
Exotic plants often face different conditions from those experienced where they are native. The general issue of how exotics respond to unfamiliar environments within their new range is not well understood. Phenotypic plasticity has historically been seen as the primary mechanism enabling colonize large, environmentally diverse areas. However, work indicates that can evolve quickly, suggesting contemporary evolution may be more important in invasion ecology than previously appreciated. To...
Enhancing biodiversity in cropping systems is suggested to promote ecosystem services, thereby reducing dependency on agronomic inputs while maintaining high crop yields. We assess the impact of several diversification practices above- and belowground services by reviewing 98 meta-analyses performing a second-order meta-analysis based 5160 original studies comprising 41,946 comparisons between diversified simplified practices. Overall, enhances biodiversity, pollination, pest control,...
Drastic biodiversity declines have raised concerns about the deterioration of ecosystem functions and motivated much recent research on relationship between species diversity functioning. A functional trait framework has been proposed to improve mechanistic understanding this relationship, but rarely tested for organisms other than plants. We analysed eight datasets, including five animal groups, examine how well a trait-based approach, compared with more traditional taxonomic predicts seven...
Significance Decades of research have fostered the now-prevalent assumption that noncrop habitat facilitates better pest suppression by providing shelter and food resources to predators parasitoids crop pests. Based on our analysis largest pest-control database its kind, surrounding farm fields does affect multiple dimensions control, but actual responses pests enemies are highly variable across geographies cropping systems. Because often not enhance biological more information about local...
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...
There is a lack of quantitative syntheses fragmentation effects across species and biogeographic regions, especially with respect to life-history traits. We used data from 24 independent studies butterflies moths wide range habitats landscapes in Europe North America test whether traits associated dispersal capacity, niche breadth reproductive rate modify the effect habitat on richness. Overall, richness increased patch area connectivity. Life-history improved explanatory power statistical...
