Occurrence of behaviours in 40 captive- and 40 wild-born monkeys and statistical comparisons.

The mean percentages of occurrence (with regard to the 240 scans) and standard error means (SEM) per populations are reported below for a selection of collected variables. The behavioural diversity is the mean number of distinct behaviours observed during the 240 scans. The abbreviations “B.” and “d.” stand for behaviour and distance. Statistics and significant p-values in Mann-Whitney U tests comparing captive- and wild-born animals are reported in the right column (*: p<0.05;**: p<0.01;***: p<0.001).
