  1. BM = body mass (in grams, centred value); IT = simultaneous infestation by I. trianguliceps larvae, nymphs or both; 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. Random effect = identity of the study site. σ2 = The variance attributable to random effect. sd = Standard deviation of σ2. The number of observations is 304.
