Life History Traits in Two Drosophila Species Differently Affected by Microbiota Diversity under Lead Exposure.

ABSTRACT: Life history traits determine the persistence and reproduction of each species. Factors that can affect life history traits are numerous and can be of different origin. We investigated the influence of population origin and heavy metal exposure on microbiota diversity and two life history traits, egg-to-adult viability and developmental time, in Drosophila melanogaster and Drosophila subobscura, grown in the laboratory on a lead (II) acetate-saturated substrate. We used 24 samples, 8 larval and 16 adult samples (two species × two substrates × two populations × two sexes). The composition of microbiota was determined by sequencing (NGS) of the V3-V4 variable regions of the 16S rRNA gene. The population origin showed a significant influence on life history traits, though each t
