Environmental filtering across seasons and host-associated selection shape the gut microbiome of sympatric European Sepsis dung flies

The paper examines gut microbiomes of six sympatric dung fly species and finds seasonal variation strongly influences microbiome composition, while host-specific selection retains a core microbiome.

Male gut microbiome mediates post-mating sexual selection in Drosophila

The paper investigates how gut microbiomes affect sperm competition in Drosophila by testing synthetic bacterial consortia and identifies microbial effects on sperm transfer and viability.
