Zaprionus indianus. After almost two months, the invasive species were removed and the Drosophila were monitored for another two months, according to the study. In four months, the Drosophila flies rapidly adapted new traits in approximately nine generations, according to the study. After nine generations, the flies were larger, laid fewer eggs and developed faster than flies that were not exposed to the invasive species, said Tess Grainger, lead author and postdoctoral fellow at the University of British Columbia. “It’s another demonstration that evolution can happen within just a few generations, kind of substantial evolution, Grainger said. “That gives more evidence in favor of this idea that species could potentially rapidly adapt to changing climates.” ....
E-Mail Credit: Washington State University VANCOUVER, Wash. - Loss of biodiversity in the face of climate change is a growing worldwide concern. Another major factor driving the loss of biodiversity is the establishment of invasive species, which often displace native species. A new study shows that species can adapt rapidly to an invader and that this evolutionary change can affect how they deal with a stressful climate. Our results demonstrate that interactions with competitors, including invasive species, can shape a species evolution in response to climatic change, said co-author Seth Rudman, a WSU Vancouver adjunct professor who will join the faculty as an assistant professor of biological sciences in the fall. ....
Quick Evolutionary Change Could Help Species Deal with Stressful Climate Written by AZoCleantechFeb 23 2021 Biodiversity loss caused by climate change is an ever-increasing concern globally. Another significant factor inducing biodiversity loss is the establishment of invasive species, which usually dislodge native species.

A new study has demonstrated that species have the potential to adapt quickly to an invader and that this evolutionary change could have an impact on how they handle a harsh climate. Our results demonstrate that interactions with competitors, including invasive species, can shape a species’ evolution in response to climatic change. ....
