DNA breakthrough detects genetic diversity of invasive fish

September 13, 2023 sarah JonasResearch Results

Ecologists have demonstrated that the genetic material that species shed into their environments can reveal not only the presence of the species but also a broad range of information about the genetics of whole populations — information that can help scientists trace the source of a new invasive population as well as prevent further invasion.
