Moderate Population Structure in Drosophila sturtevanti from the South American Atlantic Forest Biome.

ABSTRACT: Drosophila sturtevanti is a widely distributed Neotropical species. In South America, it is abundant and adapted to different phytophysiognomies of the Atlantic Forest biome. Reproductive, chromosomal and enzymatic studies have indicated the existence of a differentiation among D. sturtevanti populations. In this work, the level of genetic diversity and the population genetic structure were analyzed using four population groupings. One hundred and twenty-six D. sturtevanti males collected from nine forest fragments were analyzed for 11 species-specific microsatellite loci. A total of 109 alleles, ranging from 2 to 16 alleles per locus, were detected. The highest mean observed heterozygosity -H _O was estimated in samples from the largest collection are
