Three behavioural profiles resulting from hierarchical cluster analysis in wild-born animals.

<p>Following the MCA of the wild-born animals, a hierarchical cluster analysis was performed and resulted in 3 groups (n_H = 31, n_I = 8, n_J = 1). For each variable collected, the mean percentages of occurrence were calculated among the 3 groups. The radar profiles of group H (<b>panel </b><b>A)</b>, group I (<b>panel </b><b>B)</b>, and group J (<b>panel </b><b>C)</b> were created using a selection of collected variables (<b>panel </b><b>D</b>). The radar legend of the radars is explained on panel <b>D</b>. Each axis of the radar indicates the mean percentage of occurrence for a given variable: a behaviour (purple numbers from 1 to 7), a body posture (brown numbers from 8 to 12), a body orientation (red numbers from 13 to 17), a location in the cage (blue numbers from 18 to 19) or a distance to nearest peer (green numbers from 20 to 22). The abbreviations “B.”, “d.” and “env.” stand for “behaviour”, “distance” and “environment”. Significant p-values after Kruskal-Wallis tests are indicated by stars (*: p<0.05;**: p<0.01;***: p<0.001). On graphs <b>A and B</b>, significant p-values in Mann-Whitney U tests are indicated (p<0.05) by capital letters (H or I: versus cluster H or I respectively). As cluster J (<b>panel C</b>) contains only 1 animal, Mann-Whitney U tests could not be performed with its data.
