Title Dominance, leadership, and aggression: animal behavior studies during the Second World War Type Journal Article
Year 1990 Publication Journal of the History of the Behavioral Sciences Abbreviated Journal J Hist Behav Sci
Volume 26 Issue 1 Pages 3-16
Keywords *Aggression; Animals; Behavior, Animal; *Dominance-Subordination; History, 20th Century; *Leadership; Political Systems; *Social Dominance; United States
Abstract During the decade surrounding the Second World War, an extensive literature on the biological and psychological basis of aggression surfaced in America, a literature that in general emphasized the significance of learning and environment in the origins of aggressive behavior. Focusing on the animal behavior research of Warder Clyde Allee and John Paul Scott, this paper examines the complex interplay among conceptual, institutional, and societal forces that created and shaped a discourse on the subjects of aggression, dominance, and leadership within the context of World War II. The distinctions made between sexual and social dominance during this period, distinctions accentuated by the threat of totalitarianism abroad, and the varying ways that interpretations of behavior could be negotiated attests to the multiplicity of interactions that influence the development of scientific research.

Title Comparison of social ranks based on worm-running and aggressive behaviour in young domestic fowl Type Journal Article
Year 2004 Publication Behavioural Processes Abbreviated Journal Behav. Process.
Volume 65 Issue 1 Pages 79-86
Keywords Aggression; Social behaviour; Dominance; Play; Chickens; Animal welfare
Abstract Worm-running is behaviour in which a chick runs carrying a worm-like object while flock mates follow and attempt to grab the object from its beak. We hypothesised that social ranks based on worm-running frequency are stable over time and are positively correlated with social ranks based on success in aggressive interactions when older. At 8-12 days of age, we scored worm-running in 17 groups of 12 female White Leghorn chicks during three 10-min tests. Based on instantaneous scans at 5-s intervals, the bird carrying the `worm' most often was placed in rank one and so on down the rank order. These tests were repeated at 68-70 days of age. An aggression index for each bird was calculated as the number of aggressive acts given, divided by the number given and received, during three 1-h observation periods when the birds were 68-70 days. Ranks obtained in worm-running tests were positively correlated over the two age periods (P<0.05) but were not correlated with ranks based on the aggression index (P>0.05). Our results indicate that worm-running ranks are not predictive of success in aggressive interactions. Instead, worm-running fits some criteria for play.

Title Aggression and dominance in matched groups of subadult Icelandic horses (Equus caballus) Type Journal Article
Year 2007 Publication Journal of Ethology Abbreviated Journal J. Ethol.
Volume 25 Issue 3 Pages 239-248
Keywords Equus – Dominance – Aggression – Hierarchy – Steepness
Abstract Abstract&nbsp;&nbsp;We studied sex differences in the nature of aggression and dominance behaviour in two newly formed groups of 1-year-old Icelandic horses. One herd contained nine geldings, the other nine mares. The groups were matched with regard to dominance-determining traits such as age, weaning age, composition of native herd, social experience, genetic origin, body condition and maternal dominance status. High-ranking individuals of both sexes were more aggressive, high-ranking males were older, and high-ranking females had a better body condition. Frequencies of aggressions were similar in both groups. The mares reacted significantly more by showing submission upon an aggression rather than by not responding or by escalating the aggression. For the geldings, this difference was not observed due to a lower tendency to submit. A linear dominance hierarchy was found in both groups. David`s scores provided additional information regarding cardinal rank distances and were used to calculate steepness of hierarchies. The female hierarchy was somewhat steeper compared to the male hierarchy, suggesting somewhat lower despotism among males. This was mainly a consequence of the lower unidirectionality in male submission. Male contests occurred predominantly between dyads at top and mid positions, suggesting a low degree of acceptance of the hierarchy.

Title Maternal behavior of Belgian (Equus caballus) mares Type Journal Article
Year 1994 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 41 Issue 3-4 Pages 161-189
Keywords Belgian; Draft horse; Ontogeny; Maternal aggression; Maternal behavior; Nursing behavior; Recumbency response
Abstract The relationship between ten Belgian mares and their offspring was studied from the first day of foal life to 17 weeks of age. Mares and foals spent more time at greater distances from each other as foals matured. Mares exhibited the recumbency response, being in closer proximity to their foals when foals were recumbent than when they were upright. Foals initiated the majority of nursing bouts. Frequency and duration of nursing bouts and percentage of time resting recumbently declined as foals matured. Foals also terminated the their foals, and they were most likely to do so in the first month of foal life. Maternal initiation of nursing. There was usually no discernible foal response to maternal aggression. Little difference between maternal behavior directed towards colts and fillies was found for all aspects of the study. Maternal behavior in the Belgian draft horse was similar to that reported for other equid breeds.

Title Social relationships in a group of horses without a mature stallion Type Manuscript
Year 2006 Publication The Importance of Social Relationships in Horses Abbreviated Journal
Volume Chapter 4 Issue Pages
Keywords Feral horses are social animals, which have to rely on survival strategies centered on the formation of cohesive social bonds within their bands. Many problems in the husbandry of social animals such as horses, are due to the fact that the limits of their adaptive abilities are exceeded. Evidence suggests that the fundamental social characteristics of domestic horses have remained relatively unchanged. The social structure, social strategies and social interactions were investigated (3 non-consecutive years, 24 hr per day for several weeks) in long term established groups of domestic horses (mares and geldings of all ages) and a few small introduced groups, kept in (semi)natural environments. The general aim was to investigate the social needs of domestic horses. The social life of domestic horses was characterised by long lasting bonds with preferred partners which were established and maintained by allogrooming, play, proximity and dominance behaviours. Bonding partners were mainly found within the same sex-age group, but adult geldings also bonded with sub-adult mares and geldings. Adult mares were clustered in a group, while the other animals formed a second group. Among the adult mares, subgroups according to reproductive state were formed. Individuals regulated their social network by interfering with interactions between other members of the herd, which in itself is complex. An intervention is a behavioural action of one animal that actively interferes with an ongoing interaction between a dyad with the apparent aim of altering that interaction. This was verified by post-hoc analyses of disturbed and undisturbed interactions. Interventions in allogrooming or play were performed significantly more often when at least one member of the initial dyad was a preferred partner of, or familiar to (within the small introduced bands) the intervener. The stronger the preferred association in allogrooming between the intervener and member(s) of the initial dyad, the higher the probability the intervener would displace one initial member and continue allogrooming with the other. Just five behaviours were extracted which reliably reflected the dominance relations among horses. Aggression with the hind quarters was used both offensively and defensively and therefore not suitable as a reliable parameter. Individual dominance relationships were related to social experience. The implications of these findings for horse husbandry were assessed. It is argued that the execution of affiliative behaviours may be rewarding in itself, and therefore always will be a highly motivated behaviour. It is shown that social positive physical interactions (allogrooming, play) with other horses is an ethological need and therefore indispensable in modern husbandry systems. Ethological needs are so important for the animal that husbandry systems that lack the possibilities to execute such behaviours will cause chronic stress. It is concluded that all horses need physical social contact, and that horses, which lack appropriate social learning experiences during ontogeny, may be hampered in their social functioning later in life. Solutions for problems, including dominance problems, in individual social housing and group housing are presented.
