RNA editing is abundant and correlates with task performance in a social bumblebee

open access: yesNature Communications, 2019
Bumblebee workers are genetically highly similar but they show different behaviors such as brood care and foraging. Here the authors report a high level of ADAR-mediated RNA editing in the bumblebee Bombus terrestris and its weak correlation to task ...

Accuracy of occurrence and abundance estimates from insect metabarcoding

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract DNA metabarcoding—high‐throughput sequencing of barcode regions from bulk samples—has become a key tool for insect biodiversity assessment. Yet, how methodological choices affect the accuracy of metabarcoding data remains insufficiently explored. In this paper, we ask: (1) How does the lysis method (non‐destructive lysis vs.

Annual flower strips under the ‘Sweden Blossom’ initiative – how do they perform for pollinators, natural enemies and herbivores?

open access: yesAgricultural and Forest Entomology, EarlyView.
Pollinator‐targeted annual flower strips increase abundances of pollinators but also natural enemies and herbivores. Natural enemies and herbivores disperse in a taxon‐specific manner into nearby crops. Pest control by ground‐dwellers slightly increases in crop areas near the flower strips.

Distinct virome compositions and lack of viral diversification indicate that viral spillover is a dead-end between the western honey bee and the common eastern bumblebee

open access: yesCommunications Biology
Pathogen spillover events are of global concern as they have the potential to cause significant harm to the novel host species. The potential of viral spillover from the western honey bee (Apis mellifera) to other insects is well established.

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

open access: yesAgricultural and Forest Entomology, EarlyView.
We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...

The dual crisis: Climate change simultaneously drives pollinator decline and Pest outbreaks

open access: yesAgricultural and Forest Entomology, EarlyView.
Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

Full classification of static spherical vacuum solutions to bumblebee gravity with general VEVs

open access: yesPhysics Letters B
The static spherical vacuum solution in a bumblebee gravity model where the bumblebee field Bμ has a two-component space-like, light-like, and time-like vacuum expectation value bμ is studied.

The Effect of Oral Administration of dsRNA on Viral Replication and Mortality in Bombus terrestris

open access: yesViruses, 2015
Israeli acute paralysis virus (IAPV), a single-stranded RNA virus, has a worldwide distribution and affects honeybees as well as other important pollinators.

Taxonomic and functional diversity of urban bees of the world

open access: yesConservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...
