Discussion

  • males and females assumed to have same parameters although slight differences are reported in maximum size and age at maturity have been reported in KrafKova2006.
  • The parameter t_0 is fixed at 2.5 months (treated as an observation).

Facts

  • The total gestation time includes 3.5 months of delayed implantation. (Ref: AnAge)
  • no (or very little) dimorphism between sexes (Ref: KrafKova2006)
