Despite widespread concern about declines in pollination services, little is known the patterns of change most pollinator assemblages. By studying bee and hoverfly assemblages Britain Netherlands, we found evidence (pre-versus post-1980) local diversity both countries; however, divergent trends were observed hoverflies. Depending on assemblage location, frequent habitat flower specialists, univoltine species, and/or nonmigrants. In conjunction with this evidence, outcrossing plant species...
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...
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...
Abstract Concern about biodiversity loss has led to increased public investment in conservation. Whereas there is a widespread perception that such initiatives have been unsuccessful, are few quantitative tests of this perception. Here, we evaluate whether rates change altered recent decades three European countries (Great Britain, Netherlands and Belgium) for plants flower visiting insects. We compared four 20‐year periods, comparing periods rapid land‐use intensification natural habitat...
Insect pollination is important for food production globally and apples are one of the major fruit crops which reliant on this ecosystem service. It fundamentally that full range benefits insect to crop understood, if costs interventions aiming enhance be compared against themselves. Most previous studies have simply assessed yield ignored quality how these translate through economic values. In present study we examine influence services farmgate output two UK apple varieties; Gala Cox....
Abstract The global increase in the proportion of land cultivated with pollinator‐dependent crops implies increased reliance on pollination services. Yet agricultural practices themselves can profoundly affect pollinator supply and pollination. Extensive monocultures are associated a limited reduced pollination, whereas diversification enhance both. Therefore, areas where diversity has increased, or at least been maintained, may better sustain high more stable productivity crops. Given that...
Habitat loss poses a major threat to biodiversity, and species-specific extinction risks are inextricably linked life-history characteristics. This relationship is still poorly documented for many functionally important taxa, at larger continental scales. With data from five replicated field studies three countries, we examined how species richness of wild bees varies with habitat patch size. We hypothesized that the form this affected by body size, degree host plant specialization...
Understanding species distributions and the factors limiting them is an important topic in ecology conservation, including nature reserve selection predicting climate change impacts. While Species Distribution Models (SDM) are main tool used for these purposes, choosing best SDM algorithm not straightforward as plentiful can be applied many different ways. mainly to gain insight 1) overall distributions, 2) their past-present-future probability of occurrence and/or 3) understand ecological...
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 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...
Cultivation of pollinator-dependent crops has expanded globally, increasing our reliance on insect pollination. This essential ecosystem service is provided by a wide range managed and wild pollinators whose abundance diversity are thought to be in decline, threatening sustainable food production. The Western honey bee (Apis mellifera) amongst the best-monitored insects but state other less well known. Here, we review status trends all based publicly accessible databases published...
Summary 1. Habitat fragmentation can affect pollinator and plant population structure in terms of species composition, abundance, area covered density flowering plants. This, turn, may visitation frequency, pollen deposition, seed set fitness. 2. A reduction the quantity flower visits be coupled with a quality pollination service hence plants’ overall reproductive success long‐term survival. Understanding relationship between size and/or isolation limitation is fundamental importance for...
Abstract Pollinating insects provide crucial and economically important ecosystem services to crops wild plants, but pollinators, particularly bees, are globally declining as a result of various driving factors, including the prevalent use pesticides for crop protection. Sublethal pesticide exposure negatively impacts numerous pollinator life‐history traits, its influence on reproductive success remains largely unknown. Such information is pivotal, however, our understanding long‐term...
Insect pollinated mass flowering crops are becoming more widespread and there is a need to understand which insects primarily responsible for the pollination of these so conservation measures can be appropriately targeted in face pollinator declines. This study used field surveys conjunction with cage manipulations identify relative contributions different taxa two crops, beans oilseed rape. Flower visiting communities observed were distinct each crop; while visited by few bumblebee species,...
Many pollinator populations are declining, with large economic and ecological implications. Parasites known to be an important factor in the some of population declines honey bees bumblebees, but little is about parasites afflicting most other pollinators, or extent interspecific transmission vectoring parasites. Here we carry out a preliminary screening pollinators (honey bees, five species bumblebee, three wasp, four hoverfly genera bees) UK for We used molecular methods screen six bee...
Our review looks at pollinator conservation and highlights the differences in approach between managing for pollination services preserving diversity. We argue that ecosystem service management does not equal biodiversity conservation, maintaining species diversity is crucial providing resilience face of future environmental change. Management policy measures therefore need to focus on just human dominated landscapes but benefit wider including those specialised habitats. only by adopting a...
Biotic interactions have been considered as an important factor to be included in species distribution modelling, but little is known about how different types of interaction or strategies for modelling affect model performance. This study compares methods including interspecific models bees, their brood parasites, and the plants they pollinate. Host–parasite among bumble bees (genus Bombus : generalist pollinators parasites) specialist plant–pollinator between Centris Krameria flowers were...
