Microbiome analysis of social carpenter bees
Rachel Vannette and members of her lab, including 2021 cohort member Michael Yu, used 16S sequencing to determine that the social carpenter bees Xylocopa sonorina and Xylocopa tabaniformis orpifex share microflora species in their crop and gut, but also host microbiomes that vary by species and geographic location. Further, their results suggest that the microbiomes of bee species with simple social groups can have characteristics typically associated with bees that have more complex social structures.
