Behavioral activity of single components of beaver castoreum was demonstrated for the first time. In four experiments samples were presented to free-ranging beaver in their family territories. First, responses to whole castoreum and anal gland secretion (AGS) from males and females were tested. Second, 24 compounds, known to be constituents of beaver castoreum, were individually screened for activity. Four of these consistently released immediate responses during the observation periods. These… 
Beaver (Castor canadensis) responses to major phenolic and neutral compounds in castoreum
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.
Neutral compounds from male castoreum of North American beaver,Castor canadensis
13 neutral compounds that had not been reported before for castoreum were identified, including two oxygen-containing monoterpenes and two linalool oxides that are not volatile enough to be detected by methods.
Bioactivity of beaver castoreum constituents using principal components analysis
North American beaver (Castor canadensis) were observed to sniff from the water and make land visits to some synthetic chemical components of castoreum placed on experimental scent mounds (ESM). In
Odorant Source Used in Eurasian Beaver Territory Marking
It is concluded that castoreum is the main scent signal used in the defense of beaver territories during winter.
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.
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.
Social Signals Involved in Scent-Marking Behavior by Cheek-Rubbing in Alpine Marmots (Marmota marmota)
Observing the response of free-ranging marmots to foreign scent marks, confirming the glandular source of the marking substance by histologic examination of the temporal gland, and identifying biologically active chemical fractions of the marked substance strongly suggests that the active territorial signal results from a synergistic interaction between several compounds.
Sexual Dimorphism in Territorial Scent Marking by Adult Eurasian Beavers (Castor fiber)
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.
Biotransformation of Aromatic Ketones by Linum usitatissimum
Acetophenone is a component of castoreum, the exudate from the castor sacs of the mature beaver [1]. Linum usitatissimum L. (Linaceae), known as flax or linseed, is a good source of oil and meal,

Abstract Using gas chromatography (GC) in conjunction with electron impact mass spectrometry and retention-time comparison, 94 compounds, ranging from 2-methyl-2-propenal to octadecanoic acid, were


A Field Bioassay of Beaver Castoreum and Some of Its Components
Beavers responded to test scents containing castoreum and the neutral and phenol components but not the carboxylic acid and amine components, and the function of odor profiles of beaver and scent mounds are discussed.

The evidence that female hamsters have a chemosensory function in reproduction is reviewed, and the recent identification of a vomeronasally detected pheromone, a protein that stimulates copulatory behavior in male hamsters is illustrated.
Chemical Communication in Galago Crassicaudatus: Investigation of the Chest Gland Secretion
The chest gland secretion appears to function as a relatively short-lived cue which facilitates communication between individuals found near each other; and a relatively persistant cue which may be used for territorial marking.
Odor Images: Responses of Beaver to Castoreum Fractions
The ideal way to bioassay a mammalian pheromone is to experiment with freely moving animals in a natural setting, and intact social units. The year-round family territories of the North American
Synthetic pheromones that promote inter-male aggression in mice.
Two volatile constituents of male mouse urine, dehydro-exo-brevicomin and 2-(sec-butyl)-dihydrothiazole, have been found active in bioassays of inter-male aggressive behavior and provoke fighting that is quantitatively and qualitatively comparable to that elicited by intact male urine.
Androgen steroids associated with boar odour as an aid to the detection of oestrus in pig artificial insemination.
The effect of aerosols containing different concentrations of 2 related steroids on the reaction to the “back pressure” test on pigs presented for insemination, in the absence of the boar, was compared with that of preputial fluid.
Chemical Signals in Callitrichid Monkeys — A Comparative Review
There are several groups of primates which provide clear morphological and behavioral evidence that chemical communication is of great importance in their social and sexual behaviors, and one of these is the family Callitrichidae, the South American marmosets and tamarins.
