Comparing the impact of landscape on the gut microbiome of Apis mellifera in Atlantic Forest and Caatinga Biomes.

ABSTRACT: The composition of the gut microbiota in animals can be influenced by a variety of intrinsic and extrinsic factors in the host, such as diet, physiological state, and genetics. This study aimed to compare the structural composition of the gut microbiota of Apis mellifera bees from two distinct Brazilian biomes, the Atlantic Forest and the Caatinga, using high throughput 16 S rRNA sequencing. We identified a core microbiota composed of seven genera present in all samples: Lactobacillus, Commensalibacter, Rhizobiaceae, Snodgrassella, Gilliamella, Orbaceae and Bifidobacterium. These taxa accounted for 63% of all bacterial genera in the dataset. Interestingly, we observed a significantly differential abundance of the genus Apibacter between bees from the two biomes, with a marked increase in b
