Discussion

  • Males are supposed to differ from females by {p_Am} only
  • In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3
  • A delay in the onset of growth had to be incorporated to match the tWw data
  • mod_1: males have equal state variables at b, compared to females

Facts

  • If eggs develop below 26 C males hatch, above 32 C females (Ref: ADW)
  • Males are smaller than females and reach puberty earlier (Ref: RoosKell1996)
