	Title	A brief note on some possible factors involved in the reactions of horses to humans			Type	Journal Article
	Year	2002	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	76	Issue	4	Pages	339-344
	Keywords	Horses; Aggressiveness; Behavioural reactions; Human-animal relationship
	Abstract	In order to investigate relationships of adult horses to humans, we developed a simple evaluation test and scores based on observations. The first reactions of 224 adult horses to the presence of an experimenter were observed and scored. All these horses belonged to the same riding school, had the same general housing conditions and were all geldings. The evaluation was based on the horse's posture. Individual differences that could be related to some extent to the breed but also to human factors emerged clearly. French saddlebreds showed more often friendly behaviour than Angloarabs, whereas thoroughbreds were more indifferent. Clear variations occurred between groups of horses that depended on different caretakers. In this school, one caretaker is responsible for the whole daily management of a group of horses and is probably a very important factor in their well-being. The effects of this daily relation to a human seemed to be involved in the reactions to a strange person. Further studies are required to investigate what, in practice, may be determinant.

	Title	*Behavioral patterns and communication in feral asses (Equus africanus)*			Type	Journal Article
	Year	1998	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	60	Issue	2-3	Pages	125-169
	Keywords	Equids; Feral asses; Behavior patterns; Facial expressions; Postures; Locomotion
	Abstract	The behavior of feral populations of the African wild ass (Equus africanus) were studied in the Northern Panamint Range of Death Valley National Monument for 20 months from 1970 to 1973 [Moehlman, P.D., 1974. Behavior and ecology of feral asses (Equus asinus). PhD dissertation, University of Wisconsin, Madison, 251 pp.; Moehlman, P.D., 1979. Behavior and ecology of feral asses (Equus asinus). Natl. Geogr. Soc. Res. Reports, 1970: 405-411]. Maintenance behavior is described and behavior sequences that were used in social interactions are quantified by sex and age class. Agonistic, sexual, and greeting behavior patterns are described and analyzed in conjunction with the responses they elicited. Mutual grooming mainly occurred between adult males, and between females and their offspring. Five types of vocalizations were distinguished: brays, grunts, growls, snorts, and whuffles. A second population was studied for 1 month on Ossabaw Island, GA (Moehlman, 1979). This population had more permanent social groups and had a higher rate of mutual grooming and foal social play.

	Title	Ontogeny of social awareness in domestic herbivores			Type	Journal Article
	Year	1998	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	57	Issue	3-4	Pages	233-245
	Keywords	Animal; Environment; Relationship
	Abstract	It is now well established that domestic animals construct responses to their environment that depend on experience and on integration of several features of the environment, including social partners. This ability to be aware of the environment is not fully developed at birth but improves and varies through the animal's life. This topic is discussed on the basis of social processes in sheep and cattle. Social relationships of an animal with its conspecifics develop with age; they do not merely depend on pre-programmed behaviours but rely at least in part on learning of characteristics of the partners. Soon after birth, a strong preferential bond establishes with the dam then to a lesser extent, the young associates to other members of the flock, especially other young. The attractiveness of the group varies later in life due to external events or to physiological state: the abrupt separation from the dam at artificial weaning strengthens bonds between peers, whereas around parturition, females are less disturbed by isolation from the group. More recently, the awareness of social partners has been described in non-social contexts: the animal modifies its responses to events according to the presence of partners, and also to their emotional state and behaviour. The effects of partners seem to depend on their relationship with the animal and also on the social motivation of that animal, which both vary during its life. We recommend study of the ontogeny of awareness using the model of social influences.

	Title	*Post-conflict friendly reunion in a permanent group of horses (Equus caballus)*			Type	Journal Article
	Year	2010	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	85	Issue	2	Pages	185-190
	Keywords	aggression; affiliative interactions; conflict resolution; horse; post conflict; behaviour; reconciliation
	Abstract	Gregarious animals living in permanent social groups experience intra-group competition. Conflicts over resources can escalate into costly aggression and, in some conditions, non-dispersive forms of conflict resolution may be favoured. Post-conflict friendly reunions, hence reconciliation, have been described in a variety of species. The aim of this study was to explore, for the first time, the occurrence of reconciliation in a group of domestic horses (Equus caballus) and learn more about strategies used to maintain group cohesion. The behaviour of seven horses living as permanent group in an enclosure for at least 2 years was observed by video for 108 h from June to August 2007. We used a Post-Conflict/Matched Control method to assess the existence of reconciliation and third-party affiliation. Behaviours recorded Post-Conflict, or during Matched Control periods, were classified as affiliative based on previous descriptions of visual communication patterns in horses. The proportion of attracted pairs over total post-conflict situations was significantly greater than the proportion of dispersed pairs, both during dyadic interactions (p < 0.001) and during triadic interactions (p = 0.002). The results of the present study show that both dyadic reconciliation and third-party post-conflict affiliative interactions form important social mechanisms for managing post-conflict situations in horses.

	Title	Decision-making processes: The case of collective movements			Type	Journal Article
	Year	2010	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	84	Issue	3	Pages	635-647
	Keywords	Consensus; Inter-individual relationships; Leadership; Self-organization; Social status
	Abstract	Besides focusing on the adaptive significance of collective movements, it is crucial to study the mechanisms and dynamics of decision-making processes at the individual level underlying the higher-scale collective movements. It is now commonly admitted that collective decisions emerge from interactions between individuals, but how individual decisions are taken, i.e. how far they are modulated by the behaviour of other group members, is an under-investigated question. Classically, collective movements are viewed as the outcome of one individual's initiation (the leader) for departure, by which all or some of the other group members abide. Individuals assuming leadership have often been considered to hold a specific social status. This hierarchical or centralized control model has been challenged by recent theoretical and experimental findings, suggesting that leadership can be more distributed. Moreover, self-organized processes can account for collective movements in many different species, even in those that are characterized by high cognitive complexity. In this review, we point out that decision-making for moving collectively can be reached by a combination of different rules, i.e. individualized (based on inter-individual differences in physiology, energetic state, social status, etc.) and self-organized (based on simple response) ones for any species, context and group size.

	Title	Deciding group movements: Where and when to go			Type	Journal Article
	Year	2010	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	84	Issue	3	Pages	675-677
	Keywords	activity synchronisation; aggregation rules; collective decisions; democracy; group decisions; sexual segregation; decision sharing; social choice theory
	Abstract	A group of animals can only move cohesively, if group members “somehow” reach a consensus about the timing (e.g., start) and the spatial direction/destination of the collective movement. Timing and spatial decisions usually differ with respect to the continuity of their cost/benefit distribution in such a way that, in principle, compromises are much more feasible in timing decision (e.g. median preferred time) than they are in spatial decisions. The consequence is that consensus costs connected to collective timing decisions are usually less skewed amongst group members than are consensus costs connected to spatial decisions. This, in turn, influences the evolution of decision sharing: sharing in timing decisions is most likely to evolve when conflicts are high relative to group cohesion benefits, while sharing in spatial decisions is most likely to evolve in the opposite situation. We discuss the implications of these differences for the study of collective movement decisions.

	Title	Dyadic relationships and operational performance of male and female owners and their male dogs			Type	Journal Article
	Year	2009	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	81	Issue	3	Pages	383-391
	Keywords	Dyadic interactions; Human-animal companions; Human-animal relationships; Human-dog dyads; Personality; Social stress
	Abstract	In the paper we investigate how owner personality, attitude and gender influence dog behavior, dyadic practical functionality and the level of dog salivary cortisol. In three meetings, 12 female and 10 male owners of male dogs answered questionnaires including the Neo-FFI human personality inventory. Their dyadic behavior was video-taped in a number of test situations, and saliva samples were collected. Owners who scored highly in neuroticism (Neo-FFI dimension one) viewed their dogs as social supporters and spent much time with them. Their dogs had low baseline cortisol levels, but such dyads were less successful in the operational task. Owners who scored highly in extroversion (Neo-FFI dimension two) appreciated shared activities with their dogs which had relatively high baseline cortisol values. Dogs that had female owners were less sociable-active (dog personality axis 1) than dogs that had male owners. Therefore, it appears that owner gender and personality influences dyadic interaction style, dog behavior and dyadic practical functionality.

	Title	Social relationships in a herd of Sorraia horses: Part II. Factors affecting affiliative relationships and sexual behaviours			Type	Journal Article
	Year	2006	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	73	Issue	3	Pages	231-239
	Keywords	Horse; Equus; Affiliative relationship; Rank; Kinship; Aggressiveness
	Abstract	The influence of age, dominance rank, kinship and aggressiveness over affiliative relationships and sexual behaviours were analysed in a herd of Sorraia horses, Equus caballus, kept under extensive management. Subjects were 10 adult mares 5-18 years old that had known each other since birth, and a stallion introduced into the group for breeding for the first time. Kinship coefficient and dominance rank were the most important factors affecting affiliative relationships. Bonds were reciprocal and stronger among mares with higher kinship. Mares spent more time in proximity to close-ranking and lower-ranking females. Mares with stronger affiliative relationships or higher relatedness were not less aggressive towards each other. Affiliative relationships between the stallion and the mares were not reciprocal: lower-ranking mares formed stronger bonds with the stallion but he preferred the less genetically related mares for proximity. However, the stallion was involved in sexual behaviours more frequently with the mares that were more genetically related to him. These results suggest that kinship beyond close relatives may affect affiliative relationships both among familiar and among unfamiliar horses. However, the influence of kinship does not imply that horses possess a kin recognition system and alternative explanations are discussed.

	Title	Behavioural asymmetry is involved in regulation of autonomic processes: Left side presentation of food improves reproduction and lactation in cows			Type	Journal Article
	Year	2005	Publication	Behavioural Brain Research	Abbreviated Journal	Behav. Brain. Res.
	Volume	161	Issue	1	Pages	75-81
	Keywords	Behavioural asymmetry; Somatic functions; Reproduction; Lactation
	Abstract	It is known that the right and left brain hemispheres differ in their ability to regulate autonomic processes in the organism. Direct unilateral stimulation of the brain provokes side-dependent endocrine, immune and other visceral reactions. Since brain hemispheres are mainly involved in the regulation of muscles and sensory organs on the contra lateral side of the body the activation of behavioural asymmetry stimulates the contra lateral half of the brain. The important theoretical and practical question of whether autonomic processes can be regulated via the behavioural asymmetry route remains unexplored. In this study, we report that the chronic presentation of an emotionally important stimulus--food--from the left side, improves reproductive performance in animals in a broad range of feeding conditions. The unilateral presentation of food can also influence lactation, but in this case the side-dependent effects are different under varying feeding conditions. This finding opens a simple practical approach to influence basic somatic functions in the organism.

	Title	“Leading According to Need” in Self-Organizing Groups			Type	Journal Article
	Year	2009	Publication	The American Naturalist	Abbreviated Journal	Am Nat
	Volume	173	Issue	3	Pages	304-312
	Keywords	behavioral synchrony, collective group decisions, democracy and egalitarianism in animals, public goods experiments, sexual segregation, social choice theory
	Abstract	Self‐organizing‐system approaches have shed significant light on the mechanisms underlying synchronized movements by large groups of animals, such as shoals of fish, flocks of birds, or herds of ungulates. However, these approaches rarely consider conflicts of interest between group members, although there is reason to suppose that such conflicts are commonplace. Here, we demonstrate that, where conflicts exist, individual members of self‐organizing groups can, in principle, increase their influence on group movement destination by strategically changing simple behavioral parameters (namely, movement speed, assertiveness, and social attraction range). However, they do so at the expense of an increased risk of group fragmentation and a decrease in movement efficiency. We argue that the resulting trade‐offs faced by each group member render it likely that group movements are led by those members for which reaching a particular destination is most crucial or group cohesion is least important. We term this phenomenon leading according to “need” or “social indifference,” respectively. Both kinds of leading can occur in the absence of knowledge of or communication about the needs of other group members and without the assumption of altruistic cooperation. We discuss our findings in the light of observations on fish and other vertebrates.
