Beaver colonies with close neighbors constructed more “scent mounds” than did isolated colonies, and the number of scent mounds at each active lodge is correlated with the distance to the nearest occupied lodge. The scent mounds were typically located at trails, also on lodges and dams. The beaver rebuilt experimentally removed scent mounds. Experimentally scent-marked unoccupied lodges were less often visited or inhabited than unscented control lodges. Resident beaver responded to artificial… 

Experimental habitat scenting inhibits colonization by beaver,Castor canadensis

The beaver is the first mammal to be shown experimentally to use intraspecific odor cues when settling in vacant habitat and Territorial pheromones may be useful as repellents for beaver or other rodents.

Factors Affecting Scent-Marking Behavior in Eurasian Beaver (Castor fiber)

It is concluded that scent marking apparently plays an important role in territory defense of the Eurasian beaver.

Scent-Marking in the Eurasian Beaver (Castor fiber) as a Means of Territory Defense

The main results showed that the number of scent marks in territories was significantly higher in spring, when dispersal of subadults normally occurs than during the rest of the year.

Potential risks of olfactory signaling: the effect of predators on scent marking by beavers

Beavers may be at great risk on territories with predators present because of the trade-off between predator avoidance and territorial defense, and the potential of predation risk as a powerful agent of counterselection on olfactory signaling behavior is demonstrated.

Resident beavers (Castor canadensis) do not discriminate between castoreum scent marks from simulated adult and subadult male intruders

There was no evidence that territorial beavers responded differentially to castoreum scent marks from intruders of different ages, and there was also no significant correlation between the mass of the scent donor and the response intensity.

The function of scent marking in beaver (Castor fiber) territorial defence

This thesis examines how scent marking in Eurasian beaver (Castor fiber) functions in territorial defence. Beavers usually deposit scent (castoreum and/or anal gland secretion (AGS)) onto small pil

Scent marking in gerbils and its possible functions

Results of the study partly support the scent-matching hypothesis and the status signaling hypothesis, but these hypotheses do not predict spatial distribution of scent marks in male gerbils, and do not account for function of scent marking in young individuals as well as an increase of scent-marking activity induced by novelty factors.

Phenolic compounds from male castoreum of the North American beaver,Castor canadensis

10 phenolic compounds have been identified in this study that were not reported in the previous papers concerning the constitution of castoreum that were either absent or not volatile enough to be detected by the methods used.

Spatial and behavioral changes by red foxes (Vulpes vulpes) in response to artificial territory intrusion

Radio-tracked dominant male and female urban foxes before and after synthetic fox urine was applied to approximately a third of their territories and compared spatial and behavioral reactions both before andAfter scent application and with foxes on territories where no urine is applied.

Conservation of the Eurasian beaver Castor fiber: an olfactory perspective

It is concluded that chemical analysis, olfactory studies and behavioural manipulations involving semiochemicals have important impacts on conservation and can generate practical solutions to problems including aiding animal capture, captive stress reduction, breeding pair formation and release site fidelity.



Territorial Function of Chin Gland Secretion in the Rabbit, Oryctolagus cuniculus (L.)

In the enclosure at Gungahlin, rabbits have been observed to mark objects in their territories with the secretion of the chin gland, as well as with urine and fæces.

Beaver Census Methods in the Rocky Mountain Region

  • K. Hay
  • Environmental Science
  • 1958
This paper is an evaluation of numerous beaver-census techniques as they apply to the Rocky Mountain region using the use of lodges, dams, slides, food caches, and scent mounds as indices of beaver numbers.

Bacterial contents of the anal and castor glands of beaver (Castor canadensis)

The bacterial fermentation hypothesis is rejected for castor gland section but remains possible for anal gland secretions based on variations seen in B. fragilis, which may be represented by several variants but facilities were not available for advanced anaerobic analysis.
