Biological invasions offer unique insights into evolution. New ancient DNA and digitized specimen data help track evolutionary changes in invasive species over time.

Area of Science:

  • Evolutionary biology
  • Ecology
  • Conservation biology

Background:

  • Biological invasions provide natural experiments for studying rapid evolution.
  • Historically, limited data on early invasion stages hindered evolutionary research.
  • Recent advancements offer new ways to access historical population data.

Purpose of the Study:

  • To review the utility of temporal data in invasion science.
  • To highlight how historical specimens and data can illuminate evolutionary processes.
  • To connect contemporary and historical invasive populations for a complete picture.

Main Methods:

  • Utilizing ancient and historical DNA (aDNA/hDNA) technologies.
  • Leveraging digitized specimen data from global herbaria and museums.

  • Analyzing data from previous invasion studies.

    • Main Results:

    • Temporal data bridge the gap between historical and contemporary invasive populations.
    • Enables the study of adaptation mechanisms, evolutionary rates, and community shifts.
    • Overcomes limitations of previous research by providing historical population context.

    Conclusions:

    • Invasive species studies are crucial for understanding evolutionary mechanisms.
    • Temporal data are essential for unlocking the full potential of invasions as evolutionary experiments.
    • Integrating historical and modern data advances invasion science and evolutionary insights.
