Area of Science:

  • Zoology
  • Physiology
  • Ecology

Background:

  • Athletic performance is crucial for survival and fitness, integrating various phenotypic traits.
  • Quantifying athletic performance in cryptic or slow-moving species like adult fire salamanders presents significant challenges.
  • Adult salamanders are less reactive than their larval stage, complicating performance assessments.

Purpose of the Study:

  • To present a rapid, simple, and low-cost method for measuring athletic performance in post-metamorphic fire salamanders (Salamandra salamandra).
  • To enable direct comparison of athletic performance between larval and terrestrial stages.
  • To facilitate studies on carryover effects in the eco-evo-devo of athletic performance.

Main Methods:

  • Terrestrial juvenile salamanders were induced to swim under controlled laboratory conditions.
  • An automatic point-mass tracking tool was employed to measure performance indicators.
  • The method ensures individuals perform at their maximal capacity, minimizing motivational variation.

Main Results:

  • Maximal and average performance indicators were successfully measured in post-metamorphic individuals.
  • The method provides objective and repeatable measures of athletic performance.
  • This approach allows for comparative analyses across different life stages.

Conclusions:

  • The developed method is effective for quantifying athletic performance in challenging species.
  • It offers a valuable tool for understanding the developmental and evolutionary basis of performance traits.
  • This technique supports research into the eco-evo-devo of animal performance.
