The binding of volatile semiochemicals to lipocalin proteins in many mammalian scent marks may provide a gradual release of volatile ligands, extending the life of airborne odour signals. We tested this by using menadione to displace semiochemical ligands from major urinary proteins (MUPs) in urine streaks obtained from adult male house mice, Mus domesticus, and assessed the responses of other males to these and to intact urine marks as they aged. Dominant male mice scent-mark their territories…

Unravelling the chemical basis of competitive scent marking in house mice

Competitive countermarking is stimulated by proteins or by nonvolatile protein-ligand complexes in male urine, while release of volatile ligands attracts attention to a competitor's scent marks.

Airborne molecules released from male mouse urine affect female exploratory behavior

The data show that male urine airborne molecules, effective at very low doses, mediate initial stimulus exploration by female mice.

Rodent Urinary Proteins: Genetic Identity Signals and Pheromones

Comparative studies of other rodents are starting to reveal considerable diversity in concentration, sexual ­dimorphism and polymorphic complexity of lipocalins in scent signals; these differences are likely to reflect species-specific requirements for recognition and ­assessment through scent.

Mice recognize recent urine scent marks by the molecular composition.

The principal component based on 2,4-dehydro-exo-brevicomin, linalool, and 2-sec-butyl-4,5-dihydrothiazole correlated negatively with countermarking and positively with the sniffing behavior, suggesting a semantic feature of fresh male mouse urine.

Regulation of volatile and non-volatile pheromone attractants depends upon male social status

Findings show that once male house mice become territorial and socially dominant, they upregulate the amount and types of excreted MUPs, which increases the intensities of volatiles and the attractiveness of their urinary scent to sexually receptive females.

The scent of urine spots of male mice, Mus musculus: Changes in chemical composition over time.

The release of the odorants in the headspace of a urine spot may code and transmit information on the deposition time of a dominant male mouse.

Structural and functional differences in isoforms of mouse major urinary proteins: a male-specific protein that preferentially binds a male pheromone.

An atypical MUP is purified and characterized from the urine of male C57BL/6J inbred mice, which is responsible for the binding of most of the male pheromone, 2-sec-butyl-4,5-dihydrothiazole, and which is also responsible for their slow release from scent marks.

Chemical communication in mammal population : urinary olfactory chemosignals in lactating female root voles (Microtus oeconomus Pallas)

It is suggested that the urine of lactating females possesses stronger sexual attraction cues because of the presence of (E)5-octadecene and (N)hexadecanoic acid, which are putative lactating pheromones, however, the specific function of the phersomones should be assessed further by bioassay.

Chemical composition of scent-gland secretions in an old world monkey (Mandrillus sphinx): influence of sex, male status, and individual identity.

The similarity of the findings to those for other mammals and in primates that are more distantly related to humans suggests a broader role for odor in primate communication than is currently recognized.



The priming effects of urine substrate marks on interactions between male house mice, Mus musculus domesticus Schwarz & Schwarz

This system appears to provide mice with up-to-date information concerning dynamic shifts in individual dominance and territory location, and individual males use this information to avoid a marked area, to evade a male likely to attack, or to challenge the dominance of a competitor, according to their own status and previous experience.

Quantitative chromatographic profiling of odours associated with dominance in male laboratory mice

The results demonstrate that murine semiochemicals are accessible to quantitative analysis at the level of the individual and also demonstrate that aggressive initiator ranks and encounter winner ranks are compatible with each other.

A human axillary odorant is carried by apolipoprotein D.

The results suggest a remarkable similarity between human axillary secretions and nonhuman mammalian odor sources, where lipocalins have been shown to carry the odoriferous signals used in pheromonal communication.

Odor-based discrimination between noncontiguous demes of wild mus

House mice ( Mus musculus ) avoid odors of members of neighboring social groups, or demes, with which they share common territorial boundaries, and recognition of group-odor complexes may be a factor in population dynamics of rodents.

Avoidance of Scent-Marked Areas Depends On the Intruder's Body Size

The prediction that male house mice of low body weight should be more likely to avoid scent-marked areas than males of high body weight was tested, and heavy mice were attracted to the artificially marked substrate.

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.
