From: Evidence for a postreproductive phase in female false killer whales Pseudorca crassidens
Fecundity plots for female false killer whales from the South African (salmon curve, labelled SA), Japanese (green curve, labelled JP) and combined (mustard curve, labelled Comb) datasets. Survivorship (proportion of animals surviving to an age) was only calculated for the combined population (dashed black line, observed survivorship). The crosses (x) represent females of known age from the combined dataset that were found to be postreproductive according to the criteria defined in the text
