question: Is there high nucleotide diversity in the Drosophila suzukii species?
answer: Native to Asia, the soft-skinned fruit pest Drosophila suzukii has recently invaded the United States and Europe. The eastern United States represents the most recent expansion of their range, and presents an opportunity to test alternative models of colonization history. There are high levels of nucleotide diversity in this species and research suggests that the recent invasions of Europe and the continental United States are independent demographic events.
