Table 1. Parameter estimates of fixed effects from the two mixed models explaining age, brood manipulation and parasite effects on telomere length (telomere model) and body mass (mass model) of nestling jackdaws. β = parameter estimate, SE = standard error, σ2 = residual variance, τ = variance, ICC = interclass correlation coefficient, CI = confidence interval. Significant parameter estimates are in bold, for variable names, in bold when significant for both models. Nestling mass was transformed to a standard normal distribution by age and brood size manipulation group. All other parameters were centered. Data on parasite infestation and telomere length for the telomere model was available for a subset of individuals present in the mass model.
