Table 1.

Results of full models corresponding to figure 2f–j. LMMs all included individual identity as random effects and assessed the effect on the response variable (change in the social metric) by the fixed effects of (i) ‘prop. assoc’ (i.e. the proportion of an individual's association held to removed/captured individuals), (ii) ‘treatment’ (i.e. whether the individual's flockmates were just captured or actually removed), (iii) the week in which the replica took place, and (iv) the interaction between ‘prop. assoc’ and ‘treatment’. The coefficient, standard error, t-value and the standard p-value are provided, along with the p-value calculated from the randomizations (p_rand).
