Figure 1: The relationship between Carnushemapterus infestation and telomere shortening in wild jackdaws. (a) Correlation between telomere length at day 5 and day 30: the red diagonal line represents no difference (no change in telomere length) and further points below the line indicate more telomere shortening. Raw data points and regression lines for C. hemapterus presence (dashed line, filled circles) and absence (solid line, open circles) are shown. (b) Telomere shortening represented with boxplots showing the median (line), the interquartile range (box) and first and third quartiles (whiskers). The shaded area represents the data point distribution (violin plot) and raw data points are shown in grey. Note that for graphical purposes telomere shortening is plotted but in the analysis telomere shortening was modelled through an interaction with age.
