摘要

我们对物种引进后不久的进化动力学知之甚少。Gray等人（2025）发现，非洲无花果蝇（Zaprionus indianus）在美国温带地区定居的一个季节内进化出更小的翅膀和更小的胸翼比，但在纬度上没有差异。这证明了该物种的快速适应能力和增强入侵性的潜力。

Digest: Rapid evolution of an annual invader, the African fig fly Zaprionus indianus.

Little is known about evolutionary dynamics shortly after species introduction. Gray et al. (2025) found that the African fig fly (Zaprionus indianus) evolved smaller wings and a decreased wing:thorax ratio within one season of colonizing a temperate region of the United States, but did not differ along a latitudinal cline. This demonstrates the species' capability for rapid adaptation and potential for enhanced invasiveness.
