Table 3.

Mean (± standard deviation) probability of obtaining a given response by admixed wolves vs. non-admixed wolves in captivity (in parentheses, for the two groups separately) in each experimental task (two asterisks denote behaviours significantly differing between admixed and non-admixed wolves, as assessed running generalized linear mixed models, whereas one asterisk denotes behaviours for which no models were run, while the behaviour was observed only in wolves or only in admixed wolves; cf. Table 1)
