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 isolated ones; (2) the number of scent markings increased significantly with the number of neighboring territories and individuals, the mean distance to all other territories, duration of territory occupancy and length of wooded banks within the territory; (3) the number of… 
Scent-Marking in the Eurasian Beaver (Castor fiber) as a Means of Territory Defense
TLDR
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.
Odorant Source Used in Eurasian Beaver Territory Marking
TLDR
It is concluded that castoreum is the main scent signal used in the defense of beaver territories during winter.
SEXUAL DIMORPHISM IN THE DEVELOPMENT OF SCENT STRUCTURES FOR THE OBLIGATE MONOGAMOUS EURASIAN BEAVER (CASTOR FIBER)
TLDR
Although the combined weight of the scent structures did not differ between the sexes, males developed significantly larger anal glands but somewhat smaller castor sacs than females, and total investment to scent structures may be limited but allocation is flexible.
Territory and group sizes in Eurasian beavers (Castor fiber): echoes of settlement and reproduction?
TLDR
It is argued that the settlement pattern and reproductive history have a lasting impact in the territorial system of beavers due to a combination of the low adult mortality, high dispersal costs, and avoidance of resource depletion.
Scent Marking in Free-Ranging Mammals. Examples: Beaver or Badger
Scent marking plays a central role in the social organization and mating behavior of mammals. This exercise on scent marking can start as a general ecological project that addresses many aspects of
Sexual Dimorphism in Territorial Scent Marking by Adult Eurasian Beavers (Castor fiber)
TLDR
It is concluded that both males and females Eurasian beavers carry out territorial behavior by scent marking, but males carry a larger part of the territorial defense during summer when females lactate.
A test of the dear enemy phenomenon in the Eurasian beaver
Abstract 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 to
Couch potatoes do better: Delayed dispersal and territory size affect the duration of territory occupancy in a monogamous mammal
TLDR
The found that individuals that established in medium‐sized territories occupied them longer as compared to individuals in small or large territories, which suggests that large territories are more costly to defend due to an increased patrolling effort and small territories might not have sufficient resources.

Patterns of scent-mounding in a population of beaver (Castor canadensis)
TLDR
The most parsimonious interpretation of function of odor cues deposited on scent-mounds is the effect on the motivational state of residents and nonresidents, increasing the confidence and reducing anxiety in residents smelling their own scent-Mound and decreasing theconfidence and increasing the readiness to flee in trespassers encountering a strange scent- mound.
The social role of scent marking in beaver (Castor Canadensis)
TLDR
It is concluded that scent mounds serve in delineating family territories and are effective in deterring transient beaver from utilizing existing but uninhabited lodges.
A Reassessment of the Function of Scent Marking in Territories
The energetic costs and the risk of injury in agonistic encounters can be reduced by prior assessment of opponents: it will generally pay low quality animals to avoid combat with one of high quality.
Pheromonal activity of single castoreum constituents in beaver,Castor canadensis
TLDR
Behavioral activity of single components of beaver castoreum was demonstrated for the first time and the response was strongest in the densest beaver population.
Population Parameters and Colony Composition of Beaver (Castor canadensis) in Southeast Ohio
TLDR
The population dynamics of beaver was studied in SE Ohio from 1974 to 1978 and only one parentprogeny pair bond formed after the over-winter loss of the adult male, however.
Phenolic compounds from male castoreum of the North American beaver,Castor canadensis
TLDR
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.
SEX DIFFERENCES IN BEHAVIOR OF BEAVERS LIVING IN NEAR-BOREAL LAKE HABITAT
TLDR
Comparative studies of how female and male North American beavers (Castor canadensis) allocate time provide a basis for understanding their life history and suggest that there is a divisiveness in their active periods.
Beaver (Castor canadensis) responses to major phenolic and neutral compounds in castoreum
TLDR
To identify compounds/mixtures that evoked responses similar to those stimulated by castoreum, a chemically complex secretion from their castor sacs, recently identified phenolic compounds, some phenolics that had been determined to be biologically active in previous studies, the neutral compound borneol, and combinations of phenolic compound, neutral compounds, and the two combined were assayed.
