Parameter estimates and their standard errors from the best-fitting mortality function for the males (M) and females (F) of each population. The Kullback–Leibler Discrepancy Calibration (KLc) measures differences between the sexes: values closer to 0.5 indicate no difference. Numbers in bold indicate a difference between the means that is unlikely to occur if the distributions of the two variables were the same.
