Fig. 3From: Differences in the oxidative balance of dispersing and non-dispersing individuals: an experimental approach in a passerine birdMean nestling body mass in relation to plot density for dispersing and philopatric foster mothers. Nestling body mass was measured at 12 days of age and corrected for between-year differences. Plot density quantiles were used to define three density classes for the sake of illustration (see Fig. 2)Back to article page
