Survival costs from OD_i-driven range of BCI_res. Each line plots the average relationship for a badger of a given age between BCI_res in a summer and b autumn and that individual’s probability of surviving to the next year. Points show individual BCI_res values for the badgers in this study; individuals are placed on the line corresponding to their age at the time of the study. Post-reproductive females have weaker associations between BCI_res and survival probability [4]; therefore, they are shown as open circles, with the difference in survival probability due to their reproductive status represented by an arrow from a closed circle on their corresponding age curve
