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 Antiaggressive activity of central oxytocin in male rats Type Journal Article
Year 2013 Publication Abbreviated Journal Psychopharmacology
Volume 229 Issue 4 Pages 639-651
Keywords Oxytocin; Offensive aggression; Social exploration; Individual variability
Abstract Rationale A substantial body of research suggests that the

neuropeptide oxytocin promotes social affiliative behaviors

in a wide range of animals including humans. However, its

antiaggressive action has not been unequivocally demonstrated

in male laboratory rodents.

Objective Our primary goal was to examine the putative

serenic effect of oxytocin in a feral strain (wild type

Groningen, WTG) of rats that generally show a much

broader variation and higher levels of intermale aggression

than commonly used laboratory strains of rats.

Methods Resident animals were intracerebroventricularly

(icv) administered with different doses of synthetic oxytocin

and oxytocin receptor antagonist, alone and in combination,

in order to manipulate brain oxytocin functioning and to

assess their behavioral response to an intruder.

Results Our data clearly demonstrate that acute icv administered

oxytocin produces dose-dependent and receptorselective

changes in social behavior, reducing aggression

and potentiating social exploration. These antiaggressive

effects are stronger in the more offensive rats. On the other

hand, administration of an oxytocin receptor antagonist

tends to increase (nonsignificantly) aggression only in

low–medium aggressive animals.

Conclusions These results suggest that transiently enhancing

brain oxytocin function has potent antiaggressive effects,

whereas its attenuation tends to enhance aggressiveness. In

addition, a possible inverse relationship between trait aggression

and endogenous oxytocinergic signaling is revealed.

Overall, this study emphasizes the importance of brain

oxytocinergic signaling for regulating intermale offensive aggression.

This study supports the suggestion that oxytocin

receptor agonists could clinically be useful for curbing heightened

aggression seen in a range of neuropsychiatric disorders

like antisocial personality disorder, autism, and addiction.

Title Conflict and postconflict behaviour in captive black-and-white snub-nosed monkeys (Rhinopithecus bieti) Type Journal Article
Year 2004 Publication Primates Abbreviated Journal Primates
Volume 45 Issue 3 Pages 197-200
Keywords Aggression/psychology; Animals; Animals, Zoo/*psychology; Colobinae/*psychology; *Conflict (Psychology); Female; Male; Observation; Sex Factors; *Social Behavior; Time Factors
Abstract Black-and-white snub-nosed monkeys (Rhinopithecus bieti) have almost never been the subject of any behavioural observations in captivity. This study was aimed at providing preliminary information about agonistic and reconciliation behaviour in a group kept at the Kunming Institute of Zoology in China. Established procedures were used for this investigation (i.e., the postconflict/matched-control method and the time-rule method). Intra-group aggression rates were quite low. Postconflict affiliation as well as selective attraction of former opponents to each other following conflicts was demonstrated. Former opponents contacted each other earlier in postconflict periods than in matched-control periods. The average conciliatory tendency of all focal individuals combined was 54.5%. After an agonistic interaction, the first affiliative contact between former aggressors usually took place within the first minute. The behaviours most often shown as first affiliations after a conflict were body contact, mount, touch, and “hold-lumbar”, of which the latter is an explicit reconciliatory gesture. Furthermore, the adult male intervened non-aggressively in 84% of all conflicts (n=25) among the adult females. Overall, the patterns of aggression and reconciliation observed in R. bieti bear many of the traits that characterise tolerant primate species.

Title Conflict and post-conflict behavior in a small group of chimpanzees Type Journal Article
Year 2002 Publication Primates Abbreviated Journal Primates
Volume 43 Issue 3 Pages 223-235
Keywords Aggression; Animals; *Conflict (Psychology); Female; Housing, Animal; Male; Pan troglodytes/*psychology; *Social Behavior
Abstract Chimpanzee research plays a central role in the discussions of conflict negotiation. Reconciliation, or the attraction and affiliation of former opponents following conflict, has been proposed as a central element of conflict negotiation in chimpanzees and various other taxa. In an attempt to expand the database of chimpanzee conflict resolution, conflict and post-conflict behavior were recorded for a small group of socially housed chimpanzees at the Chimpanzee and Human Communication Institute, at Central Washington University. Data were collected over six 6-week periods between 1997 and 2000, for a total of 840 hours of observation, resulting in a substantial post-conflict (PC) and matched control (MC) data set. The data demonstrate this group's tendencies to maintain visual contact and closer proximity after conflicts. Dyadic corrected conciliatory tendencies ranged between 0 – 37.5% and averaged 17.25% across all dyads. Individual corrected conciliatory tendencies ranged between 5.8 and 32%. The results of this study combined with recent publications on captive and free-ranging chimpanzee post-conflict behavior suggest that variation in post-conflict behavior may be important to our understanding of chimpanzee conflict negotiation, and may also have implications for the design and management of captive chimpanzee enclosures and social groups, respectively.

Title Induced abortion and social factors in wild horses Type Journal Article
Year 1983 Publication Nature Abbreviated Journal Nature
Volume 303 Issue 5912 Pages 59-61
Keywords Abortion, Induced/*veterinary; Abortion, Veterinary/*etiology; Aggression/physiology; Animals; Evolution; Female; Horses/*physiology; Humans; Pregnancy; Sexual Behavior, Animal/*physiology
Abstract Much evidence now suggests that the postnatal killing of young in primates and carnivores, and induced abortions in some rodents, are evolved traits exerting strong selective pressures on adult male and female behaviour. Among ungulates it is perplexing that either no species have developed convergent tactics or that these behaviours are not reported, especially as ungulates have social systems similar to those of members of the above groups. Only in captive horses (Equus caballus) has infant killing been reported. It has been estimated that 40,000 wild horses live in remote areas of the Great Basin Desert of North America (US Department of Interior (Bureau of Land Management), unpublished report), where they occur in harems (females and young) defended by males. Here I present evidence that, rather than killing infants directly, invading males induce abortions in females unprotected by their resident stallions and these females are then inseminated by the new males.

Title Eavesdropping and animal conflict Type Journal Article
Year 2001 Publication Proceedings of the National Academy of Sciences of the United States of America Abbreviated Journal Proc. Natl. Acad. Sci. U.S.A.
Volume 98 Issue 16 Pages 9177-9180
Keywords *Aggression; Animals; *Behavior, Animal; *Conflict (Psychology); Models, Theoretical
Abstract Fights between pairs of animals frequently take place within a wider social context. The displays exchanged during conflict, and the outcome of an encounter, are often detectable by individuals who are not immediately involved. In at least some species, such bystanders are known to eavesdrop on contests between others, and to modify their behavior toward the contestants in response to the observed interaction. Here, I extend Maynard Smith's well known model of animal aggression, the Hawk-Dove game, to incorporate the possibility of eavesdroppers. I show that some eavesdropping is favored whenever the cost of losing an escalated fight exceeds the value of the contested resource, and that its equilibrium frequency is greatest when costs are relatively high. Eavesdropping reduces the risk of escalated conflict relative to that expected by chance, given the level of aggression in the population. However, it also promotes increased aggression, because it enhances the value of victory. The net result is that escalated conflicts are predicted to occur more frequently when eavesdropping is possible.
