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...
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...
Animals pollinate 87% of the world's flowering plant species. Therefore, how pollinators respond to human-induced land-use change has important implications for plants and species that depend on them. Here, we synthesize published literature affects main groups pollinators: bees, butterflies, flies, birds, bats. Responses are predominantly negative but highly variable within across taxa. The directionality pollinator response varies according study design, with comparisons gradients in...
Pollinators such as bees are essential to the functioning of terrestrial ecosystems. However, despite concerns about a global pollinator crisis, long-term data on status bee species limited. We present study relative rates change for an entire regional fauna in northeastern United States, based >30,000 museum records representing 438 species. Over 140-y period, aggregate native richness weakly decreased, but declines were significant only genus Bombus . Of 187 analyzed individually, three...
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 phenology of many ecological processes is modulated by temperature, making them potentially sensitive to climate change. Mutualistic interactions may be especially vulnerable because the potential for phenological mismatching if species involved do not respond similarly changes in temperature. Here we present an analysis climate-associated shifts wild bees, most important pollinators worldwide, and compare these published studies bee-pollinated plants over same time period. We report...
Many, many more pollinators needed Numerous studies have shown that biodiversity is necessary for ecosystem function. The majority of these, however, taken place at relatively small experimental scales. Winfree et al. looked across than 3000 square kilometers relationships between and crop pollination (see the Perspective by Kremen). number wild bee species required successful rapidly increased with spatial scale, largely owing to variation in present sites degree which most abundant played...
Background. Up to 75% of crop species benefit at least some degree from animal pollination for fruit or seed set and yield. However, basic information on the level pollinator dependence contribution yield is lacking many crops. Even less known about how insect affects quality. Given that habitat loss agricultural intensification are decrease richness abundance, there a need assess consequences different components production. Methods. We used exclusion flowers inflorescences whole plant...
Despite considerable current interest in biological invasions, the common life-history characteristics of successful invaders remain elusive. The widely held hypothesis that have high reproductive rates has received little empirical support; however, alternative possibilities are seldom considered. Combining a global comparative analysis avian introductions (>2700 events) with demographic models and phylogenetic methods, we show although rapid population growth may be advantageous during...
Abstract Climate change has the potential to alter phenological synchrony between interacting mutualists, such as plants and their pollinators. However, high levels of biodiversity might buffer negative effects species‐specific shifts maintain at community level, predicted by insurance hypothesis. Here, we explore how enhance stabilise a valuable crop, apple its native We combine 46 years data on flowering phenology with historical records bee pollinators over same period. When key are...
Abstract International agreements aim to conserve 17% of Earth's land area by 2020 but include no area‐based conservation targets within the working landscapes that support human needs through farming, ranching, and forestry. Through a review country‐level legislation, we found just 38% countries have minimum requirements for conserving native habitats landscapes. We argue increasing at least 20% landscape where it is below this minimum. Such target has benefits food security, nature's...
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...
Summary Species interactions, ranging from antagonisms to mutualisms, form the architecture of biodiversity and determine ecosystem functioning. Understanding rules responsible for who interacts with whom, as well functional consequences these interspecific is central predict community dynamics stability. traits sensu lato may affect different ecological processes by determining species interactions through a two‐step process. First, life‐history govern distributions abundance, hence...
Reversing biodiversity declines requires a better understanding of organismal mobility, as movement processes dictate the scale at which species interact with environment. Previous studies have demonstrated that foraging ranges, and therefore, habitat use increases body size. Yet, ranges are also affected by other life-history traits, such sociality, influence need ability to detect resources. We evaluated effect size sociality on potential realized using compiled dataset 383 measurements...
For an animal invading a novel region, the ability to develop new behaviors should facilitate use of food resources and hence increase its survival in environment. However, need explore may entail costs such as exposing unfamiliar predators. These two opposing forces result exploration-avoidance conflict, which can be expected interfere with acquisition resources. consequences less dramatic highly urbanized environments where opportunities are common predation risk is low. We tested this...
The structure of plant–pollinator networks has been claimed to be resilient changes in species composition due the weak degree dependence among mutualistic partners. However, detailed empirical investigations consequences introducing an alien plant into are lacking. We present first cross-European analysis by using a standardized protocol assess which particular (i.e. Carpobrotus affine acinaciformis , Impatiens glandulifera Opuntia stricta Rhododendron ponticum and Solanum elaeagnifolium )...
Abstract Aim Pollination services are at risk from land use change and intensification, but responses of individual pollinator species often variable, making it difficult to detect understand community‐level impacts on pollination. We investigated changes in community composition functional diversity insect communities under a highly modified landscape. Location Canterbury region, South Island, New Zealand. Methods trapped pollinators every month for 1 year 24 sites across four types...
Abstract If climate change affects pollinator‐dependent crop production, this will have important implications for global food security because insect pollinators contribute to production 75% of the leading crops. We investigate whether warming could result in indirect impacts upon pollination services via an overlooked mechanism, namely temperature‐induced shifts diurnal activity patterns pollinators. Using a large data set on bee watermelon crops, we predict how might under various...
Summary Understanding the relationships between trait diversity, species diversity and ecosystem functioning is essential for sustainable management. For functions comprising two trophic levels, matching interacting partners should also drive functioning. However, predictive ability of unclear most functions, particularly crop pollination, where did not necessarily co‐evolve. World‐wide, we collected data on traits flower visitors crops, visitation rates to flowers per insect fruit set in...
