Figure 1From: Reproductive cessation and post-reproductive lifespan in Asian elephants and pre-industrial humansAge-specific fertility, survival and offspring production until 80 years in Asian elephants and women. (a) Elephant and (b) human age-specific fertility of ever reproducing females (dashed line) and 4-year average (solid line) shown along survival of all females born into population (elephants: n = 3037; humans: n = 8943, narrow line) and ever reproduced females only (elephants: n = 1040; humans: n = 5336, bold line). (c) Elephant and (d) human number of offspring born at each age (elephants: n = 2727 calves for 1040 females; humans: n = 27,770 offspring for 5336 women).Back to article page
