“…The squawks produced by Tibetan macaque males during copulations are similar to the squeak‐like ejaculation calls reported in other macaques [Formosan macaque, Hsu et al, ; rhesus macaque, Hauser, ; Manson, ; bonnet macaque, Hohmann, ; lion‐tailed macaque, Hohmann & Herzog, ], with the exception of one of the only terrestrial species, the stump‐tailed macaque. In the latter species, males make rhythmic pants and have more harsh calls in their repertoire with a limited use of coo calls similar to the terrestrial Barbary macaque [Bruce & Estep, ; Fischer & Hammerschmidt, ]. Although the squawk call type has similar analogues in other macaques, Tibetan macaque males seem to be unique in that they emit squawks during copulations.…”

Vocal repertoires are basic and essential components for describing vocal communication in animals. Studying the entire suite of vocal signals aids investigations on the variation of acoustic structure across social contexts, comparisons on the complexity of communication systems across taxa, and in exploration of the evolutionary origins of species-specific vocalizations. Here, we describe the vocal repertoire of the largest species in the macaque genus, Macaca thibetana. We extracted thirty acoustic parameters from call recordings. Post hoc validation through quantitative analyses of the a priori repertoire classified eleven call types: coo, squawk, squeal, noisy scream, growl, bark, compound squeak, leap coo, weeping, modulated tonal scream, and pant. In comparison to the rest of the genus, Tibetan macaques uttered a wider array of vocalizations in the context of copulations. Previous reports did not include modulated tonal screams and pants during harassment of copulatory dyads. Furthermore, in comparison to the rest of the genus, Tibetan macaque females emit acoustically distinct copulation calls. The vocal repertoire of Tibetan macaques contributes to the literature on the emergence of species-specific calls in the genus Macaca with potential insights from social, reproductive, and ecological comparisons across species.

“…Sexual interference (SI), which is defined as any disturbance directed at a mating pair by other individuals [Nishida, 1997], has been reported in several species of prosimians, New World monkeys, Old World monkeys, and apes [Brereton, 1994; Bruce & Estep, 1992; Dixson, 1998; Gouzoules, 1974; Henzi & Barrett, 2003; Kitchen et al, 2009; Manson, 1992; Niemeyer & Anderson, 1983; Smuts, 1987; van Schaik et al, 2004; Wasser, 1983]. Interference behavior can take several forms, including highly aggressive acts such as fighting, chasing, and threatening that serve to terminate mating activities (sexual interruption) as well as milder forms of interference such as touching, sniffing, playing with or climbing on the copulating pair (sexual harassment) [Bruce & Estep, 1992] that result in a reduced likelihood of mating to ejaculation. Sexual coercion also may be viewed as a type of precopulatory interference behavior, especially if it results in restricting a female's access to potential mating partners during her periovulatory period [Manson, 2011].…”

“…In the case of chacma baboons ( Papio ursinus ), for example, high ranking males were found to direct aggressive attacks at estrous females in an attempt to prevent them from mating with lower ranking resident males and nonresident males [Kitchen et al, 2009]. Alternatively, males may compete directly with each other to monopolize access to fertile females by exhibiting high levels of intra‐sexual intolerance and aggression, especially during the breeding season [Bruce & Estep, 1992; Dixson, 1998; Dunbar, 2000; Kummer, 1968; Pradhan & van Schaik, 2008; Preuschoft & Paul, 2000]. SI as a form of intra‐sexual reproductive competition among female primates has received less attention [Clutton‐Brock, 2009; Emery Thompson et al, 2008] despite the fact that in several taxa females attempt to gain reproductive advantages and control the mating opportunities of other females through ovulatory suppression [i.e.…”

Sexual interference (SI), which is defined as any disturbance directed to a mating pair by other individuals, has been reported in several primate species. It is widely suggested that successful harassers experience improved mating success by increasing their access to reproductive partners as well as by reducing the mating success of rivals. Although theories of primate sexual conflict highlight male intra-sexual mating competition, females also are reported to actively disrupt copulations between mating partners. In this study, we investigated SI in a multilevel troop of Golden snub-nosed monkeys (Rhinopithecus roxellana) inhabiting the Qinling Mountains, China. Behavioral observations of 11 one-male units (OMU) that comprised the multilevel troop were conducted from September 2007 to May 2008. During this period 17.1% of 652 documented intra-OMU sexual encounters were characterized either by mild or aggressive forms of harassment. Sexual harassment was typically performed by a single individual (91.9%), and in 75.7% of cases the harasser was an adult or sub-adult female. The frequency of female harassment was positively correlated with the number of adult and sub-adult females residing in an OMU, and resulted in a significant decrease in matings ending in ejaculation. We found that the amount of SI a female received was not a significant predictor of her reproductive success. However, females who conceived during the mating season directed higher levels of harassment at other females than females who did not conceive. We evaluate the strength of the sexual competition hypothesis and the hormonally modulated aggression hypothesis in explaining patterns of SI in female Golden snub-nosed monkeys.

“…Percentages of disrupted interactions, both total and per age class, were lower than in the northern species (COX & LE BOEUF 1977). In Primates rate of disruption seems to be linked to rank per se, and not to specific individual traits (BRUCE & ESTEP 1992), while in both species of elephant seals tendency and capability to disrupt varied also between high ranking males. Disruptors were older, more mature and more dominant than disrupted males, who usually were subadults, and disruption usually happened near harems, while interactions with isolated females were disrupted less frequently.…”

Female southern elephant seals are expected to adopt behaviours that reduce the costs of male harassment. We studied the strategies and tactics of harassment reduction in two populations, at Punta Delgada (Valdés Peninsula, Argentina) and at Sea Lion Island (Falkland Islands) during five breeding seasons in all. Females synchronized their breeding activities to reduce harassment risk, and rarely bred alone to reduce the likelihood of encounters with subadult males. Females showed a clear preference for larger harems, that guaranteed a reduced harassment risk: movements between arrival on land and parturition were mostly from smaller to larger harems, and the likelihood of abandonment was lower for large harems. Females protested against approaching males in the vast majority of interactions, regardless of the social context and the status of the interacting male, but protest varied with female breeding status and male phenotype. Frequency of protest of individual females decreased linearly from the beginning of oestrus to departure to sea. Interactions with mature males were less protested. The frequency of protest linearly decreased with increase in age class, and mating attempts by males of higher status and dominance rank were less often protested. Most of this variation with male phenotype, however, was due to the higher probability of older and more dominant males to interact with oestrus females that had an intrinsicly lower tendency to protest. Protest variation in relation to male phenotype was more parsimoniously explained as a consequence of differential access of males to oestrus females rather than of female selectivity. Protests had a role in disruption of mating attempts, although the phenotype of interactors was more important: adult, large and dominant males disrupted interactions regardless of incitation by female protest.
