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.”

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.

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.

Washington [US], February 22 (ANI): The findings of a new study suggested that species on earth can rapidly adapt to an invader, and it is this evolutionary change in them that can affect how they deal with a stressful climate or competition.
