Summary

Researchers in ecology and evolution are shifting from null hypothesis testing to model selection for data analysis. This approach confronts competing hypotheses simultaneously, offering a robust alternative for biological inferences.

Area of Science:

  • Ecology
  • Evolutionary Biology

Background:

  • Traditional null hypothesis testing is being re-evaluated in ecology and evolution.
  • A shift towards data-driven biological inferences is emerging.

Purpose of the Study:

  • To introduce and outline the steps of model selection.
  • To highlight the implementation of model selection in ecological and evolutionary research.
  • To present model selection as an alternative to null hypothesis testing.

Main Methods:

  • Simultaneously confronting multiple competing hypotheses with data.
  • Utilizing model selection to identify the single best model or to derive inferences from weighted model support.

Main Results:

  • Model selection is well-established in fields like molecular systematics and mark-recapture analysis.

  • The adoption of model selection is expanding into diverse areas such as molecular evolution and landscape ecology.

    • Conclusions:

    • Model selection provides a valuable alternative to traditional null hypothesis testing.
    • This approach is particularly beneficial when multiple hypotheses are plausible in ecological and evolutionary studies.
