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)
