	Title	Counter aggression and reconciliation in Assamese macaques (Macaca assamensis)			Type	Journal Article
	Year	2002	Publication	American journal of primatology	Abbreviated Journal	Am. J. Primatol.
	Volume	56	Issue	4	Pages	215-230
	Keywords	Aggression; Animals; Female; Macaca; Male; Phylogeny; Sex Factors; *Social Behavior; Social Dominance
	Abstract	Patterns of aggressive and affiliative behavior, such as counter aggression and reconciliation, are said to covary in the genus Macaca; this is referred to as the systematic variation hypothesis. These behavior patterns constitute a species dominance style. Van Schaik's [1989] socioecological model explains dominance style in macaques in terms of within- and between-group contest competition. Dominance style is also said to correlate with phylogeny in macaques. The present study was undertaken to examine phylogenetic and socioecological explanations of dominance style, as well as the systematic variation hypothesis. We collected data on counter aggression and reconciliation from a habituated group of Assamese macaques (Macaca assamensis) at the Tukeswari Temple in Assam, India. The proportion of agonistic episodes that involved counter aggression was relatively low. Counter aggression, however, occurred more often among males than among females, and it was most common when females initiated aggression against males. The conciliatory tendency for this group of Assamese macaques was 11.2%. The frequency of reconciliation was low for fights among males and for fights among females, but reconciliation was particularly rare for opposite-sexed opponents. Female social relationships were consistent with the systematic variation hypothesis, and suggest a despotic dominance style. A despotic dominance style in Assamese macaques weakens the correlation between dominance style and phylogeny in macaques, but it is not inconsistent with the socioecological model. Male-female relationships were not well explained by the despotic-egalitarian framework, and males may well have more tolerant social relationships than do females. Sex differences need to be considered when categorizing species according to dominance style.

	Title	Measuring social behavior: social dominance			Type	Journal Article
	Year	1986	Publication	Journal of animal science	Abbreviated Journal	J. Anim Sci.
	Volume	62	Issue	4	Pages	1120-1129
	Keywords	Aggression; Agonistic Behavior; Animals; Behavior, Animal; Cattle; Chickens; Competitive Behavior; Female; Horses; Male; Social Dominance; Swine
	Abstract	Social dominance develops more slowly when young animals are kept in intact peer groups where they need not compete for resources. Learned generalizations may cause smaller and weaker animals to accept subordinate status readily when confronted with strangers that would be formidable opponents. Sexual hormones and sensitivity to them can influence the onset of aggression and status attained. After dominance orders are established, they tend to be stable in female groups but are less so in male groups. Psychological influences can affect dominance relationships when strangers meet and social alliances within groups may affect relative status of individuals. Whether status associated with agonistic behavior is correlated with control of space and scarce resources needs to be determined for each species and each kind of resource. When such correlations exists, competitive tests and agonistic behavior associated with gaining access to scarce resources can be useful to the observer in learning about dominance relationships rapidly. Examples are given to illustrate how estimates of social dominance can be readily attained and some strengths and weaknesses of the various methods.

	Title	The organization of agonistic relations within two captive groups of Java-monkeys (Macaca fascicularis)			Type	Journal Article
	Year	1977	Publication	Zeitschrift für Tierpsychologie	Abbreviated Journal	Z. Tierpsychol.
	Volume	44	Issue	3	Pages	225-282
	Keywords	Age Factors; Aggression; Animals; Behavior, Animal/physiology; Competitive Behavior/physiology; Fear; Female; Haplorhini; Humans; Macaca/physiology; Macaca fascicularis/physiology; Male; Sex Factors; Social Behavior; Social Dominance
	Abstract	The paper offers a detailed quantitative descripition of the distribution of agonistic activities over the members of two groups of Java-monkeys (Macaca fascicularis). These groups lived in captivity and were well-established: i.e. they had an extensive network of genealogical relationships. The study pays special attention to agonistic interactions with three or more participants. Its main purpose is an analysis of the way dyadic agonistic relations (e.g. dominance relations) are affected by third group members and the relations among these. The paper presents data on the ontogeny of 'dependent dominance', the 'control role' of the alpha-male, and the functions of different types of alliances.

	Title	The integration of dominance and social bonding in primates			Type	Journal Article
	Year	1986	Publication	The Quarterly review of biology	Abbreviated Journal	Q Rev Biol
	Volume	61	Issue	4	Pages	459-479
	Keywords	Animals; Female; Humans; Male; Object Attachment; Primates; *Social Dominance
	Abstract	Social dominance is usually viewed from the perspective of intragroup competition over access to limited resources. The present paper, while not denying the importance of such competition, discusses the dominance concept among monkeys and apes in the context of affiliative bonding, social tolerance, and the reconciliation of aggressive conflicts. Two basic proximate mechanisms are supposed to provide a link between dominance and interindividual affiliation, namely, formalization of the dominance relationship (i.e., unequivocal communication of status), and conditional reassurance (i.e., the linkage of friendly coexistence to formalization of the relationship). Ritualized submission is imposed upon losers of dominance struggles by winners; losers are offered a “choice” between continued hostility or a tolerant relationship with a clearly signalled difference in status. If these two social mechanisms are lacking, aggression is bound to have dispersive effects. In their presence, aggression becomes a well-integrated, even constructive component of social life. In some higher primates this process of integration has reached the stage where status differences are strongly attenuated. In these species, sharing and trading can take the place of overt competition. The views underlying this “reconciled hierarchy” model are only partly new, as is evident from a review of the ethological literature. Many points are illustrated with data on a large semi-captive colony of chimpanzees (Pan troglodytes), particularly data related to striving for status, reconciliation behavior, and general association patterns. These observations demonstrate that relationships among adult male chimpanzees cannot be described in terms of a dichotomy between affiliative and antagonistic tendencies. Male bonding in this species has not been achieved by an elimination of aggression, but by a set of powerful buffering mechanisms that mitigate its effects. Although female chimpanzees do exhibit a potential for bonding under noncompetitive conditions, they appear to lack the buffering mechanisms of the males.

	Title	Primates--A natural heritage of conflict resolution			Type	Journal Article
	Year	2000	Publication	Science (New York, N.Y.)	Abbreviated Journal	Science
	Volume	289	Issue	5479	Pages	586-590
	Keywords	Aggression/psychology; Animals; Behavior, Animal; Conflict (Psychology); Female; Humans; Male; Primates; Social Behavior; Social Dominance
	Abstract	The traditional notion of aggression as an antisocial instinct is being replaced by a framework that considers it a tool of competition and negotiation. When survival depends on mutual assistance, the expression of aggression is constrained by the need to maintain beneficial relationships. Moreover, evolution has produced ways of countering its disruptive consequences. For example, chimpanzees kiss and embrace after fights, and other nonhuman primates engage in similar “reconciliations.” Theoretical developments in this field carry implications for human aggression research. From families to high schools, aggressive conflict is subject to the same constraints known of cooperative animal societies. It is only when social relationships are valued that one can expect the full complement of natural checks and balances.

	Title	Long-term memory of individual identity in ant queens			Type	Journal Article
	Year	2007	Publication	Biology Letters	Abbreviated Journal	Biol Lett
	Volume	3	Issue	5	Pages	459-462
	Keywords	Aggression; Animals; Ants/physiology; Conditioning, Operant; Evolution; Female; Memory; *Recognition (Psychology); Social Dominance
	Abstract	Remembering individual identities is part of our own everyday social life. Surprisingly, this ability has recently been shown in two social insects. While paper wasps recognize each other individually through their facial markings, the ant, Pachycondyla villosa, uses chemical cues. In both species, individual recognition is adaptive since it facilitates the maintenance of stable dominance hierarchies among individuals, and thus reduces the cost of conflict within these small societies. Here, we investigated individual recognition in Pachycondyla ants by quantifying the level of aggression between pairs of familiar or unfamiliar queens over time. We show that unrelated founding queens of P. villosa and Pachycondyla inversa store information on the individual identity of other queens and can retrieve it from memory after 24h of separation. Thus, we have documented for the first time that long-term memory of individual identity is present and functional in ants. This novel finding represents an advance in our understanding of the mechanism determining the evolution of cooperation among unrelated individuals.

	Title	Contrasts in social structure among black-and-white colobus monkey groups			Type	Journal Article
	Year	1976	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	24	Issue	1	Pages	84-92
	Keywords	Agonistic Behavior; Animals; Colobus; Copulation; Female; Haplorhini; Hierarchy, Social; Male; Social Dominance
	Abstract	Three types of Colobus guereza groups may be distinguished on the bases of size and composition, namely small one-male groups, large, one-male groups and multi-male groups. The social structure of each type of group is described in terms of the distribution of non-agonistic interactions, the frequency and distribution of agonistic behaviour and the organization of the roles of vigilance, territorial defence and leadership. A number of differences are found between the group types which appear to be related to the differences in group size and composition. It is suggested that these group types represent stages in the life-cycle of colobus groups, and that such an interpretation may help to resolve some of the conflicting reports in the literature.

	Title	6. Social dominance and serotonin receptor genes in crayfish			Type	Journal Article
	Year	2006	Publication	Current Topics in Developmental Biology	Abbreviated Journal	Curr Top Dev Biol
	Volume	74	Issue		Pages	177-199
	Keywords	Animals; Astacoidea/genetics/physiology; Humans; Receptors, Serotonin/genetics; Serotonin/physiology; *Social Dominance
	Abstract	Gene expression affects social behavior only through changes in the excitabilities of neural circuits that govern the release of the relevant motor programs. In turn, social behavior affects gene expression only through patterns of sensory stimulation that produce significant activation of relevant portions of the nervous system. In crayfish, social interactions between pairs of animals lead to changes in behavior that mark the formation of a dominance hierarchy. Those changes in behavior result from changes in the excitability of specific neural circuits. In the new subordinate, circuits for offensive behavior become less excitable and those for defensive behavior become more excitable. Serotonin, which is implicated in mechanisms for social dominance in many animals, modulates circuits for escape and avoidance responses in crayfish. The modulatory effects of serotonin on the escape circuits have been found to change with social dominance, becoming excitatory in dominant crayfish and inhibitory in subordinates. These changes in serotonin's effects on escape affect the synaptic response to sensory input of a single cell, the lateral giant (LG) command neuron for escape. Moreover, these changes occur over a 2-week period and for the subordinate are reversible at any time following a reversal of the animal's status. The results have suggested that a persistent change in social status leads to a gradual change in the expression of serotonin receptors to a pattern that is more appropriate for the new status. To test that hypothesis, the expression patterns of crayfish serotonin receptors must be compared in dominant and subordinate animals. Two of potentially five serotonin receptors in crayfish have been cloned, sequenced, and pharmacologically characterized. Measurements of receptor expression in the whole CNS of dominant and subordinate crayfish have produced inconclusive results, probably because each receptor is widespread in the nervous system and is likely to experience opposite expression changes in different areas of the CNS. Both receptors have recently been found in identified neurons that mediate escape responses, and so the next step will be to measure their expression in these identified cells in dominant and subordinate animals.
