Abstract: Horses are quite unique. In most mammals, sexes segregate and maintain bonds only during the breeding season (Clutton-Brock, 1989). Some canids, a few rodents and primate species such as gorillas, hamadryas baboons and red howler monkeys are the exception, where the same males stay with the same females all year round and over many breeding seasons. Typically, both sexes disperse at puberty in these species. In horses, it was clearly shown that the causes for female dispersal were incest avoidance and not intra-specific competition (Monard, 1996). As a rule, this is confirmed for mammal species where tenure length by males exceeds the age at first reproduction in females (Clutton-Brock, 1989). When horses are allowed to choose their mating partner freely, the inbreeding coefficient of the offspring is lower than expected should they mate randomly (Duncan et al, 1984).

Abstract: (Accepted: 23 June 2005)
Summary
Much research in animal communication is aimed at understanding the functional design
features of animal vocal signals. Our detailed analyses of the vocalizations and behavioural
responses elicited in white-faced capuchins by predators and other disturbances point to two
call variants that differ modestly in their acoustic structure and that are accompanied by
functionally distinct behavioural responses. The first variant is given exclusively to avian
predators and is almost invariably accompanied by the monkeys immediate descent from
the treetops where it is most vulnerable; therefore, we label this call variant the aerial
predator alarm?. The second variant, that differs only slightly but noticeably from the first,
is given to a wide range of snakes and mammals, including a range of species that represent
no predatory threat to the monkeys. This second call is also associated with more variable
responses from calling monkeys, from delayed retreat from the source of disturbance, to
active approach, inspection, and sometimes mobbing of the animal involved. We therefore
label this variant more generally as an “alerting call”. Although some other primate species
show a more diverse system of anti-predator calls, and the capuchins themselves may yet
be found to produce a greater variety of calls, a system of two call variants with varying
degrees of predator specificity and behavioural response is not uncommon among primates
and appears functionally appropriate for capuchins. The basic structure of the alerting call
allows conspecific listeners to localize the caller and the source of disturbance readily, thereby
allowing listeners to approach and assist in mobbing in cases where the disturbance warrants
it, or to avoid the area in cases where the disturbance is identified as a predatory threat.
Conversely, the aerial predator alarm is inherently less localizable and therefore conveys the

Abstract: We performed experiments with cichlid fish to test whether several basic aspects of dominance were the same in isolated pairs as in pairs within a social group of three or four. We found that the social context, whether a pair was isolated or within a group, strongly affected the basic properties of dominance relationships. In particular, the stability of relationships over time, the replication of relationships in successive meetings, and the extent of the loser effect were all significantly less in socially embedded pairs than in isolated pairs. We found no significant winner effect in either isolated or socially embedded pairs. These findings call into question many current approaches to dominance that do not consider social context as an important factor in dominance behavior. These findings also cast serious doubt on the validity of empirical and theoretical approaches based on dyadic interactions. Among these approaches are game theoretic models for the evolution of aggressive behavior, experimental designs evaluating how asymmetries in attributes influence the outcome of dominance

Hemelrijk, C. K. (2002). Despotic societies, sexual attraction and the emergence of male 'tolerance': an agent-based model. Behaviour, 139(6), 729–747.
Abstract: During the period when females are sexually attractive – but only then – males of certain species of primates, such as chimpanzees, allow females access to resources. Because males are usually dominant over females, such male 'tolerance' is explained as a special, reproductive strategy to gain access to females. In this paper a simpler hypothesis is proposed on the basis of an individual-based model (called DomWorld): male 'tolerance' towards females arises in 'despotic' artificial societies as a kind of 'respectful timidity', because sexual attraction automatically increases female dominance over males as a side-effect. The model consists in a homogeneous, virtual world with agents that group and perform dominance-interactions in which the effects of victory and defeat are self-reinforcing. The artificial sexes differ in that VirtualMales have a higher intensity of aggression, they start with a greater capacity to win conflicts than VirtualFemales and they are especially attracted to the opposite sex during certain periods, whereas VirtualFemales are not. I shall explain how the introduction into DomWorld of the attraction of VirtualMales by VirtualFemales leads to female dominance, why it does so only in despotic, but not in egalitarian societies, and how it leads to other phenomena that are relevant to the study of primate behaviour.
