	Title	Sexual preference of mares (Equus caballus) for individual stallions			Type	Journal Article
	Year	1993	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	38	Issue	1	Pages	1-13
	Keywords	Horse; Sexual behavior; Sexual preference; Vocalization
	Abstract	Eight mares were tested to determine if they remained near one of two stallions longer than would be expected if association was random. Six stallions were paired in 30 combinations and each mare was tested 30 times. The mares (Equus caballus) demonstrated a definite preference for individual stallions throughout the breeding season. This preference was influenced by the estrous state of the mare. During estrus, mares' preferences for stallions were positively correlated with the rate at which a given stallion vocalized. During diestrus, mares spent significantly less time in the proximity of stallions and did not exhibit any preference for individual stallions.

	Title	Significance of visual cues in choice behavior in the female zebra finch (Taeniopygia guttata castanotis)			Type	Journal Article
	Year	2002	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	5	Issue	2	Pages	91-95
	Keywords	Animals; Auditory Perception; Female; Male; Sexual Behavior, Animal; Social Behavior; Songbirds; *Visual Perception; Vocalization, Animal
	Abstract	Female zebra finches show a preference for male zebra finches over heterospecific males based solely on the auditory cues of males, such as songs. The present study was designed to investigate whether females show a similar preference for male zebra finches based solely on visual cues. Using a Y-maze apparatus, social preference of female zebra finches was studied between male zebra finches and male Bengalese finches in three experiments. In experiment 1, where female zebra finches could see and hear live male zebra finches and male Bengalese finches, the females preferred to associate with the male zebra finches. In experiment 2, using a sound-attenuated experimental apparatus, subjects could see, but not hear, male zebra finches and male Bengalese finches. The subjects did not show a significant preference for associating with zebra finches. In experiment 3, as in experiment 2, females could see live male zebra finches and male Bengalese finches in the sound-attenuated chambers. However, in experiment 3, the subjects also heard prerecorded auditory cues (i.e., songs and calls) of male zebra finches, which were presented simultaneously in both arms of the maze. Although the females could not use the auditory cues to identify the location of the male zebra finches, they preferred to associate with the male zebra finches rather than the male Bengalese finches. These results suggest that visual cues alone were effective in initiating choice behaviors by females and that auditory cues facilitate such visually based choice behaviors.

	Title	Social organization and reproduction in equids			Type	Journal Article
	Year	1975	Publication	Journal of Reproduction and Fertility. Supplement	Abbreviated Journal	J Reprod Fertil Suppl
	Volume		Issue	23	Pages	7-11
	Keywords	Animals; Behavior, Animal; Female; Male; Perissodactyla/physiology; Reproduction; Sexual Behavior, Animal; Social Behavior; Territoriality
	Abstract	There are two distinct types of social organization and, accordingly, two types of mating systems in equids. In the horse, Plains zebra and Mountain zebra, the adults live in non-territorial and cohesive one-male groups and in stallion groups. The family stallions have exclusive mating rights which are respected by all others. In Grevy's zebra and in the African and Asiatic wild asses, the stallions are permanently territorial and have exclusive mating rights within their territories. Ecological and evolutionary aspects are discussed.

	Title	Social organization of feral horses			Type	Journal Article
	Year	1982	Publication	Journal of Reproduction and Fertility. Supplement	Abbreviated Journal	J Reprod Fertil Suppl
	Volume	32	Issue		Pages	89-95
	Keywords	Animals; Animals, Wild; Female; Horses/physiology; Male; Sexual Behavior, Animal; Social Behavior; Territoriality
	Abstract	The basic social unit in feral horses is the family group consisting of one stallion, one to a few unrelated mares and their foals. Surplus stallions associate in bachelor groups. Stallions are instrumental in bringing mares together in a unit which then persists even without a stallion. The similarity of social organization in populations living in a variety of different habitats indicates that feral horses have reverted to the habits of their wild ancestors, and that domestication has had no influence on this basic behavioural feature.

	Title	Social structure			Type	Journal Article
	Year	1986	Publication	The Veterinary clinics of North America. Equine practice	Abbreviated Journal	Vet Clin North Am Equine Pract

	Keywords	Animal Communication; Animals; Animals, Domestic; Animals, Wild; Dominance-Subordination; Female; Hierarchy, Social; Homing Behavior; Horses; Male; Sexual Behavior, Animal; Social Behavior; Social Dominance
	Abstract	Socially feral horses live in stable social groups characterized by one adult male, a number of adult females, and their offspring up to 2 years of age. Extra males either live by themselves or with other males in bachelor groups. The bands occupy nondefended home ranges that often overlap. Many abnormal behaviors seen in domestic horses occur because some aspect of their normal social behavior cannot be carried out in captivity.

	Title	Suppression of behavioural and physiological oestrus in the mare by vaccination against GnRH			Type	Journal Article

	Abstract	OBJECTIVE: To examine the immunogenicity of an equine immunocontraceptive vaccine and its efficacy in controlling hormone-related behaviour. DESIGN: A total of 24 mares at two sites in Australia were vaccinated with an immunocontraceptive vaccine comprising gonadotrophin releasing hormone (GnRH) conjugated to a carrier protein in immunostimulating complex as an adjuvant. Twelve animals at each site received a placebo of adjuvant alone and served as controls for seasonal oestrus, hormonal and behaviour patterns. Animals were observed for injection site reactions, ovarian and follicular activity, and serum levels of antibody, 17beta-oestradiol and progesterone in the weeks following vaccination. Mares were also examined for oestrous behaviour by teasing with a stallion. RESULTS: All mares responded to vaccination. Two weeks following the second vaccination there was a peak in antibody response to GnRH that declined gradually over the following weeks. Commensurate with the elevated anti-GnRH antibody there was a marked effect on ovarian activity with a reduction in 17beta-oestradiol and progesterone levels in the 24 vaccinated mares. There was also a reduction of oestrus-related behaviour as determined by a teaser stallion. This effect lasted a minimum of 3 months and correlated with the initial level of antibody response. CONCLUSION: Following a conventional two-dose immunisation regime this commercially available equine immunocontraceptive vaccine was effective at inhibiting oestrous behaviour for at least 3 months. This vaccine has a high level of safety since there were no significant local reactions nor were there any adverse systemic responses to vaccination.

	Title	The nose knows who's who: chemosensory individuality and mate recognition in mice			Type	Journal Article
	Year	2004	Publication	Hormones and Behavior	Abbreviated Journal	Horm Behav
	Volume	46	Issue	3	Pages	231-240
	Keywords	Animals; Chemoreceptors/physiology; Discrimination Learning/physiology; Embryo Implantation/physiology; Female; Individuality; Major Histocompatibility Complex/physiology; Male; Mice; Neurons, Afferent/physiology; Nose/cytology/physiology; Perception/physiology; Pregnancy; Pregnancy Maintenance/physiology; Pregnancy, Animal/physiology; Receptors, Odorant/physiology; Recognition (Psychology)/physiology; Sexual Behavior, Animal/physiology; Smell/physiology; Urine/physiology; Vomeronasal Organ/cytology/physiology
	Abstract	Individual recognition is an important component of behaviors, such as mate choice and maternal bonding that are vital for reproductive success. This article highlights recent developments in our understanding of the chemosensory cues and the neural pathways involved in individuality discrimination in rodents. There appear to be several types of chemosensory signal of individuality that are influenced by the highly polymorphic families of major histocompatibility complex (MHC) proteins or major urinary proteins (MUPs). Both have the capability of binding small molecules and may influence the individual profile of these chemosignals in biological fluids such as urine, skin secretions, or saliva. Moreover, these proteins, or peptides associated with them, can be taken up into the vomeronasal organ (VNO) where they can potentially interact directly with the vomeronasal receptors. This is particularly interesting given the expression of major histocompatibility complex Ib proteins by the V2R class of vomeronasal receptor and the highly selective responses of accessory olfactory bulb (AOB) mitral cells to strain identity. These findings are consistent with the role of the vomeronasal system in mediating individual discrimination that allows mate recognition in the context of the pregnancy block effect. This is hypothesized to involve a selective increase in the inhibitory control of mitral cells in the accessory olfactory bulb at the first level of processing of the vomeronasal stimulus.

	Title	The other “closest living relative”. How bonobos (Pan paniscus) challenge traditional assumptions about females, dominance, intra- and intersexual interactions, and hominid evolution			Type	Journal Article
	Year	2000	Publication	Annals of the New York Academy of Sciences	Abbreviated Journal	Ann N Y Acad Sci
	Volume	907	Issue		Pages	97-113
	Keywords	Animals; Evolution; Female; Hominidae/physiology; Humans; Interpersonal Relations; Male; Pan paniscus/physiology; Sexual Behavior, Animal/*physiology
	Abstract	Chimpanzee (Pan troglodytes) societies are typically characterized as physically aggressive, male-bonded and male-dominated. Their close relatives, the bonobos (Pan paniscus), differ in startling and significant ways. For instance, female bonobos bond with one another, form coalitions, and dominate males. A pattern of reluctance to consider, let alone acknowledge, female dominance in bonobos exists, however. Because both species are equally “man's” closest relative, the bonobo social system complicates models of human evolution that have historically been based upon referents that are male and chimpanzee-like. The bonobo evidence suggests that models of human evolution must be reformulated such that they also accommodate: real and meaningful female bonds; the possibility of systematic female dominance over males; female mating strategies which encompass extra-group paternities; hunting and meat distribution by females; the importance of the sharing of plant foods; affinitive inter-community interactions; males that do not stalk and attack and are not territorial; and flexible social relationships in which philopatry does not necessarily predict bonding pattern.

	Title	The role of the Flehmen response in the behavioral repertoire of the stallion			Type	Journal Article
	Year	1989	Publication	Physiology & behavior	Abbreviated Journal	Physiol. Behav.
	Volume	45	Issue	6	Pages	1207-1214
	Keywords	Animals; Behavior, Animal/physiology; Circadian Rhythm; Discrimination (Psychology)/physiology; Estrus; Feces; Female; Horses/physiology; Male; Sexual Behavior, Animal/physiology; Smell/physiology; Taste/physiology; Urine
	Abstract	The role of the Flehmen response in equine behavior was investigated under field and laboratory conditions. In Experiment 1, a field study made of five stallions on pasture with between three and eighteen mares each during the season indicated the following: 1) The Flehmen response was most frequently preceded by nasal, rather than oral, investigation of substances; 2) The stallions' rate of Flehmen varied with the estrous cycles of the mares; 3) The rate of Flehmen response did not show a variation with time of day; and 4) The Flehmen response was most frequently followed by marking behaviors rather than courtship behaviors. The results suggest that the Flehmen response is not an immediate component of sexual behavior, e.g., courtship of the stallion but may be involved in the overall monitoring of the mare's estrous cycle. Therefore the Flehmen response may contribute to the chemosensory priming of the stallion for reproduction. In Experiment 2 stallions were presented with urine or feces of mares in various stages of the reproductive cycle as well as with their own or other males' urine or feces. The occurrence of sniffing and Flehmen was used to determine the discriminatory ability of the stallions. Stallions can differentiate the sex of a horse on the basis of its feces alone, but cannot differentiate on the basis of urine. This ability may explain the function of fecal marking behavior of stallions.
