Open AccessHoney bees and climate explain viral prevalence in wild bee communities on a continental scale
Viruses are omnipresent, yet the knowledge on drivers of viral prevalence in wild host populations is often limited. Biotic factors, such as sympatric managed host species, as well as abiotic factors, such as ...

Open AccessReduced nest development of reared Bombus terrestris within apiary dense human-modified landscapes
Wild bees are in decline on a local to global scale. The presence of managed honey bees can lead to competition for resources with wild bee species, which has not been investigated so far for human-modified la...

Open AccessMetabolomics-based biomarker discovery for bee health monitoring: A proof of concept study concerning nutritional stress in Bombus terrestris
Bee pollinators are exposed to multiple natural and anthropogenic stressors. Understanding the effects of a single stressor in the complex environmental context of antagonistic/synergistic interactions is crit...

Open AccessPattern of population structuring between Belgian and Estonian bumblebees
Several population genetic studies investigated the extent of gene flow and population connectivity in bumblebees. In general, no restriction in gene flow is considered for mainland populations of common bumbl...

Open AccessHoney bee-collected pollen is a potential source of Ascosphaera apis infection in managed bumble bees
The trade of bumble bees started in the early nineties for pollinator-dependent greenhouse plants. Nowadays, its rearing and transport have received public attention, since managed bees can transfer pathogens ...

Open AccessStressful conditions reveal decrease in size, modification of shape but relatively stable asymmetry in bumblebee wings
Human activities can generate a wide variety of direct and indirect effects on animals, which can manifest as environmental and genetic stressors. Several phenotypic markers have been proposed as indicators of...

Open AccessInfections of virulent and avirulent viruses differentially influenced the expression of dicer-1, ago-1, and microRNAs in Bombus terrestris
The microRNA (miRNA) pathway is well established to be involved in host-pathogen interactions. As key insect pollinators, bees are suffering from widely spreading viruses, especially honeybees and bumblebees. ...

Open AccessA century of temporal stability of genetic diversity in wild bumblebees
Since the 1950s, bumblebee (Bombus) species are showing a clear decline worldwide. Although many plausible drivers have been hypothesized, the cause(s) of this phenomenon remain debated. Here, genetic diversity i...

Open AccessDifferential expression pattern of Vago in bumblebee (Bombus terrestris), induced by virulent and avirulent virus infections
Viruses are one of the main drivers of the decline of domesticated and wild bees but the mechanisms of antiviral immunity in pollinators are poorly understood. Recent work has suggested that next to the small ...

Open AccessAbsence of Leishmaniinae and Nosematidae in stingless bees
Bee pollination is an indispensable component of global food production and plays a crucial role in sustainable agriculture. The worldwide decline of bee populations, including wild pollinators, poses a threat...
