Microbial Community Dynamics in Natural Drosophila melanogaster Populations Across Seasons

Environmental Microbiology, Volume 27, Issue 6, June 2025.
The characterisation of fungal and bacterial communities associated with three field populations of Drosophila melanogaster in Germany revealed consistent but also population‐specific changes across seasons. The seasonal microbiota variation was mostly driven by indicator species of Acetobacteraceae bacteria and Saccharomycetales yeasts.
