Table 1.

Effects of population (range-core versus range-edge), source (captive-raised versus wild-caught) and their interaction (population × source) on behavioural traits during exploration (time spent moving, rate of movement), risk-taking (proportion to emerge and latency to emerge) and neophilia (proportion to approach novel object and time spent with novel object) trials. Results for main effects are based on analyses after exclusion of non-significant interaction terms. Statistically significant values (p < 0.05) are highlighted in bold text.
