Relative telomere length (T/S ratio: mean ± s.e.) of male and female barn swallow nestlings 7 or 16 days after hatching.

<p>Values for relative telomere length at day 7 and day 16 for each individual are shown as a line.</p

Repeated-measures LMM analysis of relative telomere length at day 7 or 16 after hatching in relation to sex and brood size.

<p>Brood and nestling identity were included as a random effects. Two separate models both including sex and age, and also brood size or sibling sex ratio, respectively (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0142530#sec006" target="_blank">Statistical analyses</a>) did not disclose significant interaction effects. The effect of age was significant also after excluding the effect of sibling sex ratio. The analysis is based on 119 relative TL estimates from 60 nestlings, because the datum for one nestling at age 7 was missing.</p><p>Repeated-measures LMM analysis of relative telomere length at day 7 or 16 after hatching in relation to sex and brood size.</p

Relative telomere length (T/S ratio) of male and female barn swallow nestlings 16 days after hatching in relation to relative telomere length 7 days after hatching.

<p>The slope of the relationship for females (n = 29) was significantly larger than for males (n = 30).</p

Length of the wing chord (upper panel) or tail length (lower panel) at age 16 days in relation to relative telomere length (T/S ratio) on the same day.

<p>For wing length, the relationship was significantly positive for both males (n = 31) and females (n = 29), but was steeper in males. For tail length, the relationship for males (n = 31) was significantly positive and significantly steeper than in females (n = 29).</p

Linear mixed models of nestling morphology in relation to relative telomere length.

<p>For wing and tail length, the parameters are explicitly given to allow calculation of fitted phenotypic values. Non-significant interaction terms were removed from the final models (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0142530#sec006" target="_blank">Statistical analyses</a>). Coefficients for non-significant terms are not reported. Bolded P-values are discussed in the text.</p><p>*: these parameters are set to 0 as they are redundant.</p><p>a: t_25.3 = 5.11, P < 0.001</p><p>b: t_16.5 = 2.02, P = 0.060</p><p>c: t_51.4 = 4.30, P < 0.001</p><p>d: t_40.7 = 2.03, P = 0.049</p><p>e: t_51.6 = 4.39, P < 0.001</p><p>f: t_17.2 = 2.59, P = 0.019</p><p>g: t_51.6 = 2.86, P = 0.007</p><p>h: t_41.2 = -0.53, P = 0.597</p><p>Linear mixed models of nestling morphology in relation to relative telomere length.</p
