Discussion

  • Males are assumed to differ from females by {p_Am} and E_Hp only
  • The observed high reproduction is hard to match by the abj model; may be that allocation to reproduction starts earlier than observed maturation, or that 1.72 mg per egg is overestimated
  • mod_1: males equal to females upto b

Facts

  • Death is programmed, not by ageing; reprod once just before death (Ref: Wiki)
