Bee declines driven by combined stress from parasites, pesticides, and lack of flowers
Conserving pollinator services for crops If pollination fails, ecosystems are eroded and we will lose reliable sources of many critical foodstuffs. Focusing on the pollination services provided byExpand

Neonicotinoid Residues in Wildflowers, a Potential Route of Chronic Exposure for Bees.
In recent years, an intense debate about the environmental risks posed by neonicotinoids, a group of widely used, neurotoxic insecticides, has been joined. When these systemic compounds are appliedExpand

Widespread contamination of wildflower and bee-collected pollen with complex mixtures of neonicotinoids and fungicides commonly applied to crops.
There is considerable and ongoing debate as to the harm inflicted on bees by exposure to agricultural pesticides. In part, the lack of consensus reflects a shortage of information on field-realisticExpand

Flight performance of actively foraging honey bees is reduced by a common pathogen
Summary Sudden and severe declines in honey bee (Apis mellifera) colony health in the US and Europe have been attributed, in part, to emergent microbial pathogens, however, the mechanisms behind theExpand

No effect of low-level chronic neonicotinoid exposure on bumblebee learning and fecundity
In recent years, many pollinators have declined in abundance and diversity worldwide, presenting a potential threat to agricultural productivity, biodiversity and the functioning of naturalExpand

Larval exposure to field-realistic concentrations of clothianidin has no effect on development rate, over-winter survival or adult metabolic rate in a solitary bee, Osmia bicornis
There is widespread concern regarding the effects of agro-chemical exposure on bee health, of which neonicotinoids, systemic insecticides detected in the pollen and nectar of both crops andExpand

Qualifying pollinator decline evidence—response.
Ghazoul is accurate in pointing out that we have no population data on the majority of pollinators, that the data we do have are biased toward a small number of taxa (bumblebees, honey bees, andExpand

Assessment of pollen rewards by foraging bees
Summary The removal of pollen by flower-visiting insects is costly to plants, not only in terms of production, but also via lost reproductive potential. Modern angiosperms have evolved variousExpand

Optimal search patterns in honeybee orientation flights are robust against emerging infectious diseases
Lévy flights are scale-free (fractal) search patterns found in a wide range of animals. They can be an advantageous strategy promoting high encounter rates with rare cues that may indicate preyExpand

Monitoring Neonicotinoid Exposure for Bees in Rural and Peri-urban Areas of the U.K. during the Transition from Pre- to Post-moratorium.
Concerns regarding the impact of neonicotinoid exposure on bee populations recently led to an EU-wide moratorium on the use of certain neonicotinoids on flowering crops. Currently, evidence regardingExpand
