Fig. 2From: Differences in the oxidative balance of dispersing and non-dispersing individuals: an experimental approach in a passerine birdROMs concentration (scaled within year) in relation to plot density for dispersing and philopatric females. Plot density quantiles were used to define three density classes for the sake of illustration (low density: < 63.32 % of nest boxes occupied, high density: ≥ 74.07 %)Back to article page
