Microbiome composition shapes temperature tolerance in a Hawaiian picture-winged <i>Drosophila</i>.

ABSTRACT: Hawaiian picture-winged Drosophila are undergoing rapid biodiversity loss, with twelve species listed as endangered and others in decline. Gut microbiota are increasingly recognized as contributors to host adaptation that are capable of influencing stress tolerance, reproduction, and other fitness-related traits. We investigated the role of microbial communities in local adaptation using two populations of Drosophila basisetae from Hawaiian rainforests at 900 m and 1200 m elevation. Microbiome profiling of wild flies by high throughput amplicon sequencing revealed distinct bacterial and fungal communities between sites. Whole-genome resequencing of the two Drosophila populations identified weak but significant population genetic structure, with evidence of admixture an
