Interacting effect of parental relative telomere lengths (RTLs) on fledgling recruitment. (A) Predicted values of full model outcome showing an increase in fledgling recruitment as parental RTLs increase, but a diminishment again when both parents have very long RTLs. (B) Observed values of parental RTL and fledgling recruitment. Each point represents a mated pair, with the increasing darkness of the points indicating the increasing proportion of fledglings that recruited. Parents with similar and extreme RTLs have the lowest fledgling recruitment probabilities. Analysis was done on z-transformed values, but raw RTL’s are plotted here.
