Overview

Randomized trial reveals habitat significantly influences microbiome diversity in Hawaiian Drosophila, suggesting ecological impacts on host adaptation.

Key Points

  • This study aims to explore how habitat and ecological factors shape the microbiome variation in endemic Hawaiian Drosophila.
  • Surveyed bacterial and fungal communities from over 500 wild flies across six Hawaiian islands.
  • Measured abiotic factors including elevation, temperature, rainfall, and evapotranspiration.
  • Analyzed microbiome variation against phylogenetic relatedness among species.
  • Microbiome variation is primarily influenced by abiotic factors like elevation, with less impact from host phylogeny.
  • Identical species in different locations showed diverse microbiomes, while distantly related species in the same habitat had similar microbiomes.
  • Endemic Drosophila species exhibit different microbiomes compared to invasive species based on diversity and composition.
