We examined whether differences in thermal environment during egg incubation can permanently organize nonsocial behavior across different contexts and situations in a lizard. We incubated eggs of the Yucatan banded gecko at 3 temperatures (26, 28, and 30 °C) and raised juveniles under the same conditions until adulthood. We then subjected them to 3 behavioral tests within 2 different contexts: an open-field test and a test of antipredator behavior - stressful context (SC) and a test of feeding behavior (FB) - nonstressful context. Individuals (30 °C) of both sexes were consistently less active and showed lower frequencies of several stereotypic behaviors in the SC than did individuals (26, 28 °C). The FB revealed no effect of incubation temperature on behavior. Thus, study demonstrates that developmental plasticity may play an important role in producing variability in stress-induced behavior in lizards.
