Statistical analyses
We assessed behavioural consistency (i.e., personality) by quantifying repeatability coefficient for the nine traits using the package ‘rptR in R v.4.0.2. (R Development Core Team, 2016; Stoffel et al., 2017). Repeatability coefficient (R) calculated as ratio of group level variance over the sum of group level and residual variance gives the information about how particular trait correlates between replication in one replication unit (in our case individual). The coefficient takes value between 0 and 1. In rpt models we set the bootstrap number to 1000 in order to properly estimate confidence intervals for repeatability coefficient.
