  1. PrR is a measure of the proportion of adult female years lived post-reproductively. CB refers to captive-born elephants, WC to wild-caught. Ages B and M are the ages at 5 and 95% population fecundity, respectively, whilst eB and eM are the expected female lifespan at ages B and M (rounded to the nearest whole number)
