Abstract


The studies of the craniometric features in European beaver (Castor fiber L.,1758) were performed using the material of 25 skulls, including 12 females and 13 males from the Pomorze and Kujawy region. For each skull 30 measurements were taken to provide the grounds for the variation in craniometric features and the significance of differences between sexes. In two cases there were observed significant and in three – highly significant differences between males and females of that species. Interestingly, in the shaft of the occipital bone there was found a profound and vast fossa of the skull base.

Key words: craniometry; skull; mandible; beaver

 

KRANIOMETRIČNE ZNAČILNOSTI V POPULACIJI EVROPSKEGA BOBRA (Castor fiber L., 1758)

Povzetek: Študija kraniometričnih značilnosti evropskega bobra (Castor fiber L., 1758) je bila izvedena na 25 lobanjah 12 samic in 13 samcev evropskega bobra s področij Pomorze in Kujawy na Poljskem. Na vsaki lobanji je bilo opravljenih 30 meritev, ki so bile podlaga za ugotavljanje raznolikosti v kraniometričnih značilnostih in njihovem pomenu pri razlikah med spoloma. V dveh primerih so opazili značilne in v treh primerih zelo značilne razlike med samci in samicami. Zanimivo je, da je v zatilnici najdena globoka in obsežna jama na bazi lobanje.

Ključne besede: kraniometrija; lobanja; mandibula; bober
