Discussion

  • mod_1: v is reduced
  • mod_2: food availability is taken variable in tW data
  • nod_4: 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
