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...
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...
Ecological intensification, or the improvement of crop yield through enhancement biodiversity, may be a sustainable pathway toward greater food supplies. Such increases especially important for 2 billion people reliant on small farms, many which are undernourished, yet we know little about efficacy this approach. Using coordinated protocol across regions and crops, quantify to what degree enhancing pollinator density richness can improve yields 344 fields from 33 pollinator-dependent systems...
SummaryIn this chapter we present a synthesis of recommendations for conducting field experiments with honey bees in the context agricultural pollination. We begin an overview methods determining mating system requirements plants and efficacy specific pollinators. describe evaluating pollen-vectoring capacity at level individuals or colonies follow optimum colony stocking densities. include sections post-harvest effects pollination, management (including glasshouse enclosure) on bee...
Stingless bees are an important asset to assure plant biodiversity in many natural ecosystems, and fulfill the growing agricultural demand for pollination. However, across developing countries stingless beekeeping remains essentially informal activity, technical knowledge is scarce, management practices lack standardization. Here we profited from large diversity of beekeepers found Brazil assess impact particular on productivity economic revenues commercialization bee products. Our study...
Background. Pollinators, which provide the agriculturally and ecologically essential service of pollination, are under threat at a global scale. Habitat loss homogenisation, pesticides, parasites pathogens, invasive species, climate change have been identified as past current threats to pollinators. Actions mitigate these threats, e.g., agri-environment schemes pesticide-use moratoriums, exist, but largely applied post-hoc. However, future sustainability pollinators they requires...
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...
Abstract Body size is an integral functional trait that underlies pollination‐related ecological processes, yet it often impractical to measure directly. Allometric scaling laws have been used overcome this problem. However, most existing models rely upon small sample sizes, geographically restricted sampling and limited applicability for non‐bee taxa. consider biogeography, phylogenetic relatedness, intraspecific variation are urgently required ensure greater accuracy. We measured body as...
While an increasing number of studies indicate that the range, diversity and abundance many wild pollinators has declined, global area pollinator-dependent crops significantly increased over last few decades. Crop pollination to date have mainly focused on either identifying different guilds pollinating various crops, or factors driving spatial changes turnover observed in these communities. The mechanisms temporal stability for ecosystem functioning services, however, remain poorly...
Over the last quarter century, increasing honey bee colony losses motivated standardized large-scale surveys of managed bees (Apis mellifera), particularly in Europe and United States. Here we present first survey stingless across Latin America. Overall, 1736 beekeepers 165 meliponiculturists participated 2-year (2016-2017 2017-2018). On average, 30.4% colonies 39.6% were lost per year region. Summer higher than winter (30.9% 22.2%, respectively) but not (18.8% 20.6%, respectively). Colony...
ABSTRACT Land use change threatens global biodiversity and compromises ecosystem functions, including pollination food production. Reduced taxonomic α‐diversity is often reported under land change, yet the impacts could be different at larger spatial scales (i.e., γ‐diversity), either due to reduced β‐diversity amplifying diversity loss or increased dampening loss. Additionally, studies focus on diversity, while other important components, phylogenetic can exhibit differential responses....
1. Aspects of the flowering biology wild cashew Anacardium occidentale , an andro monoecious, self‐fertile tree, were studied in north‐east Brazil, where this species is endemic. Comparison was made among two bee species, Apis mellifera and Centris tarsata their pollination flowers using a number measures including single visits to marked flowers. 2. Cashew protandrous within day. Male greatly outnumber hermaphrodite Stigmas lose receptivity rapidly pollen quickly removed from anthers yet...
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 Habitat degradation and climate change are currently threatening wild pollinators, compromising their ability to provide pollination services cultivated plants. Landscape genomics offers powerful tools assess the influence of landscape modifications on genetic diversity functional connectivity, identify adaptations local environmental conditions that could facilitate future bee survival. Here, we assessed range‐wide patterns structure, diversity, gene flow, adaptation in stingless...
