A test of the dear enemy phenomenon in the Eurasian beaver
(Journal article; Peer reviewed, 2002)We tested the hypothesis that Eurasian beavers, Castor fiber, display the dear enemy phenomenon; that is, they respond less aggressively to intrusions by their territorial neighbours than intrusions by nonterritorial ... -
Eurasian beavers (Castor fiber) behavioral response to simulated territorial intruders
(Journal article; Peer reviewed, 2000)Eurasian beavers (Castor fiber) live in family groups that defend territories against other conspecifics. Part of this territorial defence involves constructing scent mounds near the stream bank within territories and ... -
Factors affecting scent-marking behavior in Eurasian beaver (Castor fiber)
(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 ... -
Free-ranging Eurasian beavers, Castor fiber, deposit anal gland secretion when scent marking
(Journal article; Peer reviewed, 1998)Two adult free-ranging Eurasian Beavers (Castor fiber) were observed depositing anal gland secretion at the border of thei territory byeverting the "cloaca", protruding the anal gland openings and rubbing them against the ... -
Potential risks of olfactory signaling : the effect of predators on scent marking by beavers
(Journal article; Peer reviewed, 2006)Mammals scent mark their territories to advertise occupancy and ownership. However, signaling with scent for territorial defense can have a negative effect by advertising an individual’s presence and location to predators. ... -
Resident beavers (Castor canadensis) do not discriminate between castoreum scent marks from simulated adult and subadult male intruders
(Journal article; Peer reviewed, 2006)Subadult intruding beavers (Castor spp.) could be expected to pose a higher threat than adults to territory holders because, unlike adults who usually own a territory, subadults need to acquire a territory and a mate to ... -
Scent-marking in the Eurasian beaver (Castor fiber) as a means of territory defense
(Journal article; Peer reviewed, 1998)Beaver (Castor spp.) normally scent mark by depositing castoreum and/or anal gland secretion on scent mounds close to the water's edge. The aim of this study was to investigate the hypothesis that the Eurasian beaver (C. ... -
Sexual dimorphism in territorial scent marking by adult eurasian beavers (Castor fiber)
(Journal article; Peer reviewed, 2006)Mammalian scent marking is often associated with territorial defense. However, males and females may demonstrate different activity patterns and play different roles. Female mammals nurture the young during lactation, while ... -
Territoriality and group sizes in Eurasian beavers (Castor fiber): echoes of settlement and reproduction?
(Journal article; Peer reviewed, 2005)According to current theories of territoriality, an animal is expected to defend the smallest area that can provide resources for maximisation of reproduction, known as the lsquoeconomically defendablersquo area. In group ... -
Territoriality and time budgets in beavers during sequential settlement
(Journal article; Peer reviewed, 1994)Beavers (Castor fiber) were sequentially released into a previously unoccupied area. The settlement of the animals approximated an ideal despotic distribution: they successively settled in rich habitat and then in poor ... -
Tool-use in a display behaviour by Eurasian beavers ( Castor fiber )
(Journal article; Peer reviewed, 2007)Tool use is rare amongst rodents and has never been recorded in connection with agonistic displays. We witnessed a behaviour, stick display (StD), involving tool use in free-living Eurasian beavers (Castor fiber) that we ...
