Limited population structure but signals of recent selection in introduced African Fig Fly (Zaprionus indianus) in North America.

ABSTRACT: Invasive species have devastating consequences for human health, food security, and the environment. Many invasive species adapt to new ecological niches following invasion, but little is known about the early steps of adaptation. Here, we examine the population genomics of a recently introduced drosophilid in North America, the African Fig Fly, Zaprionus indianus. This species is likely intolerant of subfreezing temperatures and recolonizes temperate environments yearly. We generated a new chromosome-level genome assembly for Z. indianus. Using resequencing data of over 200 North American individuals collected over 4 years in temperate Virginia, along with a single collection from subtropical Florida, we tested for signatures of population structure and adaptation within invasive populati
