First factorial plane of the multiple component analyses (MCA) in captive-and wild-born animals.
Behaviours, postures, distances to nearest peer, body orientations and locations expressed by the 40 socially-housed captive- (panel A) or wild- (panel B) born cynomolgus monkeys were submitted to MCA. The individuals are represented by bold black letters, accounting for the clusters to which they belong according to the cluster analysis following the MCA. Squares represent active modalities: grouped behaviours, grouped postures, distances to nearest peer, body orientations and locations in the cage. On each axis is reported the percentage of the total variance accounted for by each factor. The abbreviations “B”, “D”, “L” and “O” stand for “behaviour”, “distance”, “location” and “orientation”. See Table S1 and S2 for a detailed description of each variable.
