Global invasions of the western honeybee (Apis mellifera) and the consequences for biodiversity
TL;DR: Although honeybee invasions seem to have had little if any effect on biodiversity of native pollinators so far, it is nevertheless caution against transporting honeybees around the globe, and particularly advise against importing foreign Apis species into tropical ecosystems.

Increased efficiency in identifying mixed pollen samples by meta-barcoding with a dual-indexing approach
Wiebke Sickel,Markus J. Ankenbrand,Gudrun Grimmer,Andrea Holzschuh,Stephan Härtel,Jonathan Lanzen,Ingolf Steffan-Dewenter,Alexander Keller +7 more
TL;DR: A new primer-adapter design for high throughput sequencing with the Illumina technology that uses a dual-indexing strategy, where sample-specific combinations of forward and reverse identifiers attached to the barcode marker allow high sample throughput with a single sequencing run.
Evaluating multiplexed next-generation sequencing as a method in palynology for mixed pollen samples
Alexander Keller,Nadja Danner,Gudrun Grimmer,Markus J. Ankenbrand,K. von der Ohe,W. von der Ohe,Simone Rost,Stephan Härtel,Ingolf Steffan-Dewenter +8 more
TL;DR: Next-generation sequencing of amplicons from the highly variable, species-specific internal transcribed spacer 2 region of nuclear ribosomal DNA presents a useful and efficient workflow to identify pollen at the genus and species level without requiring specialised palynological expert knowledge.
Honey bee foraging ecology: Season but not landscape diversity shapes the amount and diversity of collected pollen.
TL;DR: The observed increase in foraging distances with decreasing landscape diversity suggests that honey bees compensated for lower landscape diversity by increasing their pollen foraging range in order to maintain pollen amount and diversity.
Season and landscape composition affect pollen foraging distances and habitat use of honey bees
TL;DR: SNH and mass-flowering crops can reduce foraging distances of honey bees colonies at different scales and seasons with possible benefits for the performance of honey bee colonies.
