Overview

Randomized trial examines the impact of incubation temperature on habitat choice and fitness in lizards, suggesting long-term behavioral effects.

Key Points

  • The study aimed to determine how incubation temperatures during embryonic development influence adult habitat choice and associated fitness.
  • Eggs of the jacky dragon lizard were incubated at various ecologically relevant temperatures.
  • Adult lizards' habitat choice, movements, and perch heights were quantified approximately two years post-hatching.
  • Effects on fitness correlates, including growth rate and reproductive success, were assessed.
  • Lizards from cooler incubation temperatures moved more frequently and perched lower than those from warmer temperatures.
  • Individuals incubated at intermediate temperatures chose high-quality habitats more often than those from cool or warm treatments.
  • Body size was found to be the most significant factor associated with growth and reproductive success.
