Discussion

  • Males are assumed to differ from females by {p_Am} only
  • Time of birth in tL data is unkown; it assumed to be 250 d before the first data-point, to bring down v, but this might be an under-estimate
  • End of acceleration is assumed to coincide with puberty
  • mod_1: males have equal state variables at b, compared to females

Facts

  • Programmed death, not by ageing (Ref: Wiki)
  • Reduced ink sac, short or no plantonic stage (Ref: QuetOrdi2009)
