The improvement in body condition during the treatment period was significantly higher in the random group as compared with the other three groups (see sampling event ? social treatment interaction in the electronic supplementary material, table S3a). 232, s.e. = 0.074, t₂₃₆ = 3.123, p = 0.008), while body condition was not affected by the experimental treatment in the other three treatment groups (all p > 0.198).

The rate of increase in H/L ratio was significantly higher in the high-exploratory group, and marginally higher in the low-exploratory and variable groups as compared with the random group (see sampling event ? social treatment interaction in the electronic supplementary material, table S3b). Post-hoc tests showed a weak decrease in H/L ratio in the random group between the two sampling events (? = 0.378, s.e. = 0.166, t₂₃₅ = 2.270, p = 0.093), while it remained unchanged in the other three groups (all p > 0.484). H/L ratio decreased only in the random group, while increased in the other three groups (figure 1b).

The increase in oxidative damage during the treatment period was significantly higher in the low-exploratory group and marginally higher in the high-exploratory group as compared with the random group, while the variable and random groups did not differ (see sampling event ? social treatment interaction in the electronic supplementary material, table S3c). The post-hoc tests revealed that individuals from the variable group showed a age levels between the two sampling events (? = 0.439, s.e. = 0.179, t₂₃₃ = 2.452, p = 0.058), whereas birds from the other three treatment groups were not affected by the experimental manipulation (all p > 0.140). MDA levels (i.e. oxidative damage to lipids) increased in high- and low-exploratory groups, but decreased in the variable and random groups (figure 1c).

Individuals’ character was not associated with the private answers inside physiological status itself or perhaps in communication with public treatment, and therefore try dropped throughout the activities (dining table step 1, electronic supplementary procedure, table S3). Constitutive natural defense mechanisms increased through the treatment as the one another agglutination and you can lysis ratings more than doubled between them sampling situations, and you may males got higher looks position than just females (dining table step one, electronic second thing, table S3).

(b) Shannon diversity out-of group’s identity

To assess the role of personality diversity of experimental social groups, we tested whether the calculated Shannon diversity index predicted the individual’s physiological responses to social treatment. The sampling event ? Shannon diversity interaction was highly significant for body condition and oxidative damage (figure 2), while it was non-significant for H/L ratio and the activity of constitutive innate immunity as measured by agglutination and lysis (table 2, electronic supplementary material, table S4). The main effect of Shannon diversity was non-significant for each response variable (table 2, electronic supplementary material, table S4). Regarding the significant interactions, we found that body condition increased (? = 0.146, s.e. = 0.067, t_{twenty four.9} = 2.195, p = 0.038), while oxidative damage to lipids (i.e. MDA) decreased (? = –0.170, s.e . = 0.067, t_66.0 = 2.532, p = 0.014) with increasing personality diversity in the post-treatment sample (i.e. after exposure to social treatment), while these two response variables were unrelated to Shannon diversity in the pre-treatment sample (i.e. prior to social treatment; all p > 0.413; table 2, electronic supplementary material, table S4, figure 2). The other three response variables (i.e. H/L ratio and agglutination and lysis) were unrelated to Shannon diversity in either the pre-treatment or the post-treatment samples (all p > 0.231 and all p > 0.578, respectively).
