    • Factors affecting scent-marking behavior in Eurasian beaver (Castor fiber) 

      Rosell, Frank; Nolet, Bart A. (Journal article; Peer reviewed, 1997)
      We tested the hypothesis that a main function of territory marking in Eurasian beaver (Castor fiber) is defense of the territory. The results showed that. (1) beaver colonies with close neighbors scent-mark more often than ...
