  1. BM = the vole’s body mass (in grams, centred value); Session = trapping sessions (5 levels); I. ric abundance = the abundance of I. ricinus (nymphs and adults together) on vegetation (per 100 m of flag dragging) in the study site over the study period; I. ric_L infestation = simultaneous I. ricinus larva infestation. Random effect = identity of the study site. σ2 = The variance attributable to random effect. sd = Standard deviation of σ2. The number of observations is 551.
