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...
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...
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...
Crop productivity is improved by ecosystem services, including pollination, but this should be set in the context of trade-offs among multiple management practices. We investigated impact pollination services on coffee production, considering variation fertilization, irrigation, shade cover, and environmental variables such as rainfall (which stimulates flowering across all plantations), soil pH, nitrogen availability. After accounting for interventions, bee abundance production (number...
Ecologists have long suspected that species are more likely to interact if their traits match in a particular way. For example, pollination interaction may be the proportions of bee's tongue fit plant's flower shape. Empirical estimates importance trait-matching for determining interactions, however, vary significantly among different types ecological networks. Here, we show ambiguity empirical studies arisen at least parts from using overly simple statistical models. Using simulated and...
Insect pollination underpins apple production but the extent to which different pollinator guilds supply this service, particularly across varieties, is unknown. Such information essential if appropriate orchard management practices are be targeted and proportional potential benefits species may provide. Here we use a novel combination of effectiveness assays (floral visit effectiveness), field surveys (flower visitation rate) dependence manipulations (pollinator exclusion experiments)...
Abstract Apple is considered the most important fruit crop in temperate areas and profitable production depends on multiple ecosystem services, including reduction of pest damage provision sufficient pollination levels. Management approaches present an inherent trade‐off as each affects species differently. We quantified direct indirect effects management (organic vs. integrated management, IPM ) richness, 85 apple orchards three European countries. also how habit composition influenced...
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%...
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...
Pollinators face multiple pressures and there is evidence of populations in decline. As demand for insect-pollinated crops increases, crop production threatened by shortfalls pollination services. Understanding the extent current yield deficits due to identifying opportunities protect or improve quality through management therefore international importance. To explore "pollination deficits," where maximum not being achieved insufficient pollination, we used an extensive dataset on a globally...
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...
Abstract Hairiness is a salient trait of insect pollinators that has been linked to thermoregulation, pollen uptake and transportation, pollination success. Despite its potential importance in ecology, hairiness rarely included pollinator analyses. This likely due the lack standardized efficient methods measure hairiness. We describe novel methodology uses stereomicroscope equipped with live measurement module software quantitatively two components hairiness: hair density length. took...
Abstract Functional traits mediate the response of communities to disturbances (response traits) and their contribution ecosystem functions (effect traits). To predict how anthropogenic influence services requires a dual approach including both trait concepts. Here, we used response–effect conceptual framework understand local landscape features affect pollinator functional diversity pollination in apple orchards. We worked 110 orchards across four European regions. Orchards differed...
ABSTRACT Knowledge sharing between scientists and nonscientist stakeholders is necessary to implement research findings in an appropriate effective manner within the context of environment conservation sectors. Yet scientific ecological knowledge rarely shared transferred effectively. This special section has addressed a number opportunities barriers improvement communication transfer with respect environmental management tropical settings. A main challenge seen creating ‘impact‐metric’...
ABSTRACT Conserving tropical ecosystems is one of the foremost challenges 21st century. Lately, conservation efforts have focused on advancing through dialogue and interaction with among diverse stakeholders. Knowledge sharing, specifically transfer scientific knowledge, can raise ecological awareness stakeholders necessary to facilitate dialogue, yet communication research local rarely effectively implemented. Such a gap potentially undermines management natural resources. The papers in...
Climate change is altering the phenology of trophically linked organisms, leading to increased asynchrony between species with unknown consequences for ecosystem services. Although phenological mismatches are reported from several ecosystems, experimental evidence multiple services hardly available. We examined how shift apple trees affected abundance and diversity pollinators, generalist specialist herbivores predatory arthropods. stored potted in greenhouse or cold store early spring...
Abstract. Ecological intensification has been embraced with great interest by the academic sector but is still rarely taken up farmers because monitoring state of different ecological functions not straightforward. Modelling tools can represent a more accessible alternative measuring functions, which could help promote their use amongst and other decision-makers. In case crop pollination, modelling traditionally followed either mechanistic or data-driven approach. Mechanistic models simulate...
Abstract Pollination is an ecosystem service that directly contributes to agricultural production, and can therefore provide a strong incentive conserve natural habitats support pollinator populations. However, we have yet consistent convincing pollination valuations effectively slow the conversion of habitats. We use coffee in Kodagu, India, illustrate uncertainties involved estimating costs benefits services. First, fully account for obtained by agroforests are attributable from wild bees...
How does diversity in plant cultivars and endophyte infection affect higher trophic levels? We manipulated the number of (1 or 4) (-E, +E, both, -E +E) potted Lolium perenne plants left aphids their parasitoids to assemble naturally. Aphid biomass were not influenced by our treatments, while parasitised (mummies) was significantly on mixed stands than monocultures. The effect endophytes stronger monocultures with most mummies found endophyte-free stands. Although did differ among cultivars,...
