Discussion
- Males are assumed to differ from females by {p_Am} and E_Hp only
- In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3
Facts
- Between 23 and 28 C, males develop from eggs, below and above the range females (Ref: COSEWIC)
- Males are larger tha females (Ref: Wiki)
