Behavioural profiles of the 5 clusters and statistical comparisons.

The mean percentages of occurrence (with regard to the 90 scans) and standard error means (SEM) per cluster are reported below for a selection of collected variables. The “behavioural diversity” is a mean number of distinct behaviours observed during the 90 scans. The “behavioural switch” between successive scans was calculated using a score for each scan: 0 if the behaviour was the same as in the previous scan, or 1 if it was different; the scores were added up within one session and transformed in a percentage with regard to the 15 scans of a session. The abbreviation “B.” stands for behaviour. Significant p-values after Kruskal-Wallis test are indicated by stars (*) in the left column (*: p(4,32)). Group sizes including these individuals are indicated in the corresponding columns. See Table S1 for full Kruskal-Wallis statistics.
