Facts

  • Litter weight amounts to 53,2
  • Females mature after opening eyes and while still unweaned. So called suckling maturity. (ref: BoycBoyc1988, Fran1956)
  • Age at weaning/maturity earlier for solitary mother than mothers in groups. (ref: BoycBoyc1988)
  • most numerous rodent in field ecosystems in most of europe; might reproduce all year round in favorable conditions; most dangerous pest of the field cultures. (ref: Migu1969)
  • food uptake by females increases slightly during pregnancy while it increases drastically during lactation. (ref: Migu1969)

Discussion

  • There is variability in reported timing of weaning and puberty;we assume that weaning and puberty happen at the same maturity level.
  • We assume that f=1 during lactation but that it differs afterwards in the different studies;this assumption makes a difference
