Venom profile of the European carpenter bee Xylocopa violacea: Evolutionary and applied considerations on its toxin components

open access: yesToxicon: X, 2022
Modern venomics is increasing its focus on hymenopterans such as honeybees, bumblebees, parasitoid wasps, ants and true wasps. However solitary bees remain understudied in comparison and the few available venom studies focus on short melittin-like ...

Solitary Bee Life History Traits and Sex Mediate Responses to Manipulated Seasonal Temperatures and Season Length

open access: yesFrontiers in Ecology and Evolution, 2019
The effects of climate change on solitary bee species, the most diverse and abundant group of wild pollinators, remain poorly understood, limiting our ability to forecast consequences for bee-plant interactions and pollination services.

Diverse microbiota identified in whole intact nest chambers of the red mason bee Osmia bicornis (Linnaeus 1758). [PDF]

open access: yesPLoS ONE, 2013
Microbial activity is known to have profound impact on bee ecology and physiology, both by beneficial and pathogenic effects. Most information about such associations is available for colony-building organisms, and especially the honey bee. There, active

Gut microbiota variation of a tropical oil-collecting bee species far exceeds that of the honeybee

open access: yesFrontiers in Microbiology, 2023
IntroductionInterest for bee microbiota has recently been rising, alleviating the gap in knowledge in regard to drivers of solitary bee gut microbiota. However, no study has addressed the microbial acquisition routes of tropical solitary bees.

EVALUATING SOLITARY BEE NESTING PREFERENCE – DOES THE GROUND COVER MATTER?

open access: yes, 2023
Solitary bees make up the majority of the world’s 20,000 total species of bees. Over 70% of solitary bees nest underground. Bee fitness is likely determined, in part, by the proximity to appropriate nesting sites. Identifying ground cover management that
