The InBIO Barcoding Initiative Database: DNA barcodes of Iberian Bees [PDF]

Biodiversity Data Journal
Bees are important actors in terrestrial ecosystems and are recognised for their prominent role as pollinators. In the Iberian Peninsula, approximately 1,100 bee species are known, with nearly 100 of these species being endemic to the Peninsula.

Evolution of Peripheral Visual System in the Apoidea: A Role for Food Item Mobility? [PDF]

Ecol Evol
Since larger compound eyes and ocelli altogether improve vision, one may expect that insects specialised in chasing very mobile resources possess such morphological optimisation. By analysing 77 species of bees and wasps, we have found that wasps had larger eyes, but not larger ocelli, than bees.

Morphology, pollen preferences and DNA-barcoding of five Austrian species in the Colletes succinctus group (Hymenoptera, Apidae) [PDF]

Deutsche Entomologische Zeitschrift, 2021
Most species of the Colletes succinctus group sensu Noskiewicz, 1936 are taxonomically uncertain. This study has chosen an integrative approach, including pollen analysis, morphology, male genitalia, morphometry, cuticle sculpture and DNA-barcoding (CO1)

Separating Sampling Bias From Abundance Shows That Different Methods Catch Different Wild Bees. [PDF]

Ecol Evol
Comparing community sampling methods' relative taxonomic biases is critical to interpreting the data they collect, but measuring bias explicitly is difficult when methods also produce different sample sizes. Here, we control for absolute abundance while comparing sample composition and richness of three common methods for sampling wild bee communities.

Multiple Key Hosts and Network Structure Shape Viral Prevalence Across Multispecies Communities of Bees. [PDF]

Ecol Lett
This study develops a quantitative framework that integrates field data, epidemiological models, simulations, and Bayesian inference to identify key viral hosts in multispecies bee communities. By estimating species‐specific R0 values from flower‐visitor networks and viral screening, we show that honeybees, as well as other wild bees, can drive the ...
