Discussion
- Males are assumed to differ from females by {p_Am} only
- mod_2: males have equal state variables at b, compared to females
- mod_3: Pseudo-data point k is used, rather than k_J; Parameter t_R is added, replacing clutch interval t_N. Postnatal T is based on PrinPres1991, see get_T_Aves. See further the revision page, theme puberty
Facts
- no change in yolk composition during development (Ref: PrinDiet1997)
