Survival with inbreeding index. Kaplan-Meier plot showing that highly inbred birds (IR>0.35, n=18, open markers) had lower proportional survival than relatively outbred birds (IR<0.35, n=294, closed markers; log rank: Χ2=8.37, p=0.004). Although presented categorically here for the purpose of illustration, inbreeding index was treated as a continuous variable in all other analyses.
