Discussion

  • males are assumed to differ from females by {p_Am} only
  • functional response is assumed to reduce somewhat near fledging
  • mod_1: v is reduced
  • mod_2: Puberty is assumed to coincide with fledging with a waiting time to first brood
  • 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
