Felids are the main group of animals, other than ungulates, that display flehmen behavior during sociosexual interactions. In ungulates the behavior is evoked most readily by olfactory investigation of urine and vaginal secretions, and is believed to be involved in the transport of fluid-borne chemical stimuli, such as sex pheromones, from the oral cavity to the vomeronasal organ. In this study of cats flehmen was virtually always preceded by nasooral contact with the stimulus material… Expand
Preliminary study of the development of the Flehmen response in Equus caballus
This study tested the flehmen response on male and female foals throughout their pre-pubertal period and found no significant differences between male andFemale foals for the following variables: latency to fleh men, duration of flehman, frequency of fleHmen and sniffs. Expand
Spontaneous discrimination of urine odours in wild African lions, Panthera leo
The results indicated that lion urine has the potential to signal depositor sex and social group, and that lions can use urine to discriminate males from females and residents from nonresidents, and demonstrate the functional relevance of scent marking in African lions. Expand
Nasopalatine Ducts and Flehmen Behavior in the Mandrill: Reevaluating Olfactory Communication in Old World Primates
Flehmen, particularly in a given male, occurred most often in response to odorants derived from male, as opposed to female, conspecifics, and elicited more responses than did odorants from contracepted females. Expand
Detection of estrus in Indian blackbuck: behavioural, hormonal and urinary volatiles evaluation.
The findings of the present study suggest that the non-invasive approaches like reproductive behaviours, faecal steroids and estrus-specific urinary volatiles could serve as good indicators for detection of estrus for blackbuck. Expand
Effects of androgens on behavioral and vomeronasal responses to chemosensory cues in male terrestrial salamanders (Plethodon shermani)
It is hypothesized that increased circulating androgen levels in male P. shermani enhance chemoreception through morphological, behavioral, and physiological mechanisms and whether androgens potentially modulate responsiveness of the VNO to female-derived (as opposed to male-derived) chemosensory cues.

The flehmen response and pseudosuckling in a captive, juvenile Southern sea otter (Enhydra lutris nereis).
Among the three sea otters currently housed at the Oregon Zoo, the juvenile female's flehmen response only occurred following interactions with the older female and was always preceded by the pseudosuckling or anogenital nosing, licking or nibbling behavior. Expand
Potential use of domestic cat (Felis catus) urinary extracts for manipulating the behavior of free-roaming cats and wild small felids
Cat urinary extract evoked careful sniffing and the flehmen response in the bobcat, a different species, suggesting that it may be useful in programs for conservation of small endangered felids. Expand
Responses of Eastern red-backed salamanders (Plethodon cinereus) to chemical cues of prey presented in soluble and volatile forms
It is indicated that soluble prey cues alone are sufficient to trigger salamander foraging behaviour, and that temperature influences this foraging response, which supports the notion that the vomeronasal system plays an important role in prey detection, but suggests that volatile cues are also investigated by some salamanders when soluble prey cue cues have been detected.

11 – Communication by Chemical Signals: Behavior, Social Recognition, Hormones and the Role of the Vomeronasal and Olfactory Systems
This chapter, which has a focus on vertebrates, starts with a discussion on terminology, especially the term pheromone. A major part of the chapter addresses the discrimination and recognition ofExpand
The characteristic response of domestic cats to plant iridoids allows them to gain chemical defense against mosquitoes
It is found that the iridoid nepetalactol is the major component of silver vine that elicits this potent response in cats and other felids and provides an important example of chemical pest defense using plant metabolites in nonhuman mammals. Expand


Flehmen in male goats: role in sexual behavior.
It was found that most flehmen responses were made after mounting or ejaculatory responses, suggesting that VNO stimulation, like regular olfactory stimulation, may function during copulatory activity to maintain sexual interest. Expand
Flehmen and vomeronasal organ function in male goats
It was concluded that, if the dye represented a behaviorally significant non-volatile material (sex attractant), only the goats that showed flehmen would have detected the material from VNO chemoreception. Expand
Flehmen Behavior and Vomeronasal Organ Function
The flehmen or lip-curl behavior displayed by males of most ungulate and felid species is a prominent, but poorly understood, aspect of sociosexual behavior. The behavior is sexually dimorphic inExpand
Effects of castration on sexual behavior of tropical male goats
Compared with observations on other species, an unusually high percentage of these goats showed a long-term retention of sexual activity after castration, however, there was a significant decrement in frequency of ejaculatory responses within one week afterCastration. Expand
Vomeronasal organ cannulation in male goats: Evidence for transport of fluid from oral cavity to vomeronasal organ during flehmen
A chronic cannulation procedure is described which allows for sampling vomeronasal organ (VNO) contents repeatedly in freely moving conscious subjects and the concentration of dye found in the VNO was markedly higher after the occurrence of flehmen than non-flehmen. Expand
Medial preoptic-anterior hypothalamic lesions and sociosexual behavior of male goats

The results illustrate the apparent universal effects of MP-AH lesions on copulatory behavior in mammalian species and point to a specific effect of the lesions in disturbing a male's copulating performance while sparing other expressions of sexual arousal. Expand
Medial preoptic-anterior hypothalamic lesions in prepubertal male cats: Effects on juvenile and adult sociosexual behaviors
Different behavioral systems influenced by theMP-AH area showed varying degrees of plasticity, as found in dogs, prepubertal MP-AH lesions enhanced and accelerated testosterone secretion in cats. Expand
Female sexual responses in male cats facilitated by olfactory bulbectomy and medial preoptic/anterior hypothalamic lesions.
The results support the concept that there exists, within the brains of male animals, the neural basis for the display of female as well as male sexual responses and that certain brain operations may potentiate the displayof female responses. Expand
The occurrence of flehmen in a marsupial — The hairy-nosed wombat (Lasiorhinus latifrons)
The evolution and occurrence of flehmen is discussed in terms of social structure at mating, and sexuality of adult males, in addition to its previously suggested role of aiding olfactory analysis of urine. Expand

The results demonstrate that androgenization involves both a suppression of female behavioural patterns, and the development of male patterns; these are not mutually exclusive. Expand
