Widespread dispersal of the microsporidian Nosema ceranae, an emergent pathogen of the western honey bee, Apis mellifera.
The economically most important honey bee species, Apis mellifera, was formerly considered to be parasitized by one microsporidian, Nosema apis. Recently, [Higes, M., Martín, R., Meana, A., 2006.Expand

Nosema ceranae has infected Apis mellifera in Europe since at least 1998 and may be more virulent than Nosema apis
Nosema ceranae, a microsporidian formerly regarded as confined to its Asiatic host Apis cerana, has recently been shown to parasitise Apis mellifera and to have spread throughout most of the world inExpand

Cryptic species diversity in a widespread bumble bee complex revealed using mitochondrial DNA RFLPs
Cryptic species diversity is thought to be common within the class Insecta, posing problems for basic ecological and population genetic studies and conservation management. Within the temperateExpand

Queen-worker conflict over male production and the sex ratio in a facultatively polyandrous bumblebee, Bombus hypnorum: the consequences of nest usurpation.
Evolutionary conflicts among social hymenopteran nestmates are theoretically likely to arise over the production of males and the sex ratio. Analysis of these conflicts has become an important focusExpand

Rarity and decline in bumblebees - : A test of causes and correlates in the Irish fauna
Abstract Bees are believed to be in decline across many of the world’s ecosystems. Recent studies on British bumblebees proposed alternative theories to explain declines. One study suggested thatExpand

Estimating the density of honeybee colonies across their natural range to fill the gap in pollinator decline censuses.
Although pollinator declines are a global biodiversity threat, the demography of the western honeybee (Apis mellifera) has not been considered by conservationists because it is biased by the activityExpand

A sting in the spit: widespread cross‐infection of multiple RNA viruses across wild and managed bees
Summary Declining populations of bee pollinators are a cause of concern, with major repercussions for biodiversity loss and food security. RNA viruses associated with honeybees represent a potentialExpand
