- 요약Gut microorganisms play important roles in the health and development of many animals. The eusocial corbiculate bees, including honey bees and bumble bees, have recently been discovered to harbour a unique gut microbial community. In this dissertation, I characterize the novel bacterial species that make up the bee gut microbiota, with emphasis on their evolution and their relationship with the host organism. I axenically culture and formally describe three bee-associated bacterial species: Snodgrassella alvi, Gilliamella apicola, and Apibacter adventaris. Their genomes were sequenced, along with that of another dominant microbiota member, Lactobacillus Firm-5.I present evidence of metabolic complementarity and niche partitioning between S. alvi and G. apicola, suggesting a mechanism for their co-existence within the gut. In-vivo experiments with multiple strains of these bacteria from different bee species show that strains can be specialized, such that they can only colonize particular hosts. Finally, I conduct wide sampling across the corbiculate bee phylogeny and reveal a dynamic evolutionary history behind the microbiota, marked by multiple gains and losses of gut associates, and the presence of generalist strains as well as specialists.
