We aimed to test the link between temperament traits and plasticity of defensive behavior in collared peccary. Twelve adult animals were submitted to three short-term challenges for temperament assessment. Each individual was submitted to four sequential tests with different degrees of risk, allowing the plasticity of defensive behavior to be assessed. The negatively correlated amounts of time spent on wariness and exploratory behaviors during the short-term challenges were combined to rate the animals in a one-dimensional shyness-boldness temperament continuum. Temperament traits do not imply total behavioral consistency, as peccaries show behavioral plasticity of defensive behavior across risk conditions. We verified a link between temperament traits and defensive behavior: the higher the shyness score, the more time collared peccaries spent on wariness behaviors in the higher risk condition. The significant correlations between temperament traits and behavioral plasticity of collared peccaries across risk conditions warrant further investigation to understand the impact of temperament trait and behavioral plasticity on their post-release success.
