Overview

Analysis reveals insights into heritability of growth metrics in lizards, indicating climate may influence adaptive potential.

Key Points

  • Lower growth rates and larger asymptotic sizes were observed in lizards from colder environments, suggesting environmental impacts on growth.
  • Using two datasets, the study found significant heritability in growth curve parameters, varying by sex and environmental conditions.
  • Non-linear animal models indicated that the shape of growth curves holds more heritable genetic variance than the overall size differences.
  • The adaptive potential of growth varies between sexes, showing earlier advantages for males and later ones for females, influenced by their distinct life histories.
