Area of Science:

  • Animal Welfare Science
  • Herpetology
  • Zoo Biology

Background:

  • Evidence-based care is crucial for zoo animals, but understudied species lack sufficient data.
  • Preference tests offer a method to enhance animal care and welfare by understanding individual needs.

Purpose of the Study:

  • To assess substrate, enclosure feature, and lighting preferences of five aquatic turtles housed together.
  • To compare seasonal preferences for enclosure features and lighting in an indoor environment.

Main Methods:

  • Utilized 24-hour remote monitoring to observe five aquatic turtles (wood, Blanding's, and spotted turtles).
  • Assessed preferences for substrate, enclosure features (land, logs, water), and lighting (ambient, heat, UV).
  • Compared preferences between winter and summer months.

Main Results:

  • Wood and Blanding's turtles showed substrate preferences; spotted turtles did not.
  • Enclosure feature preferences remained consistent across seasons, but usage of land, logs, and water varied individually.
  • Turtles preferred ambient lighting over heat or UV lamps, consistent across seasons.

Conclusions:

  • Individual aquatic turtle preferences for substrates and lighting can be identified.
  • Consistent enclosure feature preferences suggest stable needs, but individual variation in use is notable.
  • Findings support the development of tailored, evidence-based care strategies to enhance turtle welfare in zoological settings.
