Schematic representation of how mean level, and within- and among individual variances were expected to differ between environments. Each dot with vertical line represents one theoretical individual. The black line represents the extent of variation in behaviour that is observed across observations of a single individual (i.e., within-individual variance, VR). The change in the length of black lines indicates the change in within-individual variance (VR) across environments. The variation among dots represents the variation among individuals in average phenotype (i.e., among-individual variance, VI). The dashed line indicates a change in population-level mean
