“…Owren and Rendall (2001) notably illustrated their “structure-affective processing” hypothesis with calls produced by baboons and macaques, contact and threat calls having indirect affective effects, distress and alarm calls having direct affective effects. Interestingly, we found a similar pattern in red-capped mangabeys whose social organization is based on relatively frequent peaceful and agonistic interactions and on a strong hierarchy like most baboons and macaques (Rowell, 1988; Dolado and Beltran, 2012). In contrast, guenons' social organization is based on rare physical interactions and on a discrete hierarchy (Gautier-Hion and Gautier, 1978; Rowell, 1988; Lemasson et al, 2006), and they displayed a different pattern here, with threat calls having an acoustic structure more likely to have direct affective effects on listeners.…”

“…Like most forest guenons, De Brazza's and Campbell's monkeys' social organization is based on rare physical interactions and a discrete hierarchy (Gautier-Hion and Gautier, 1978; Rowell, 1988; Lemasson et al, 2006). Conversely, the social organization of red-capped mangabeys, like most baboons and macaques, is based on relatively frequent peaceful and agonistic interactions and a strong hierarchy (Rowell, 1988; Dolado and Beltran, 2012). …”

“…They originate from comparable African tropical forests, and were studied here in similar, controlled captive conditions. They present interesting differences in their social systems, in both social organization (discrete hierarchy in guenons vs. strong hierarchy in mangabeys, rare physical interactions in guenons vs. relatively frequent physical interactions in mangabeys) and social structure (small family groups for De Brazza's monkeys, medium-size harems for Campbell's monkeys, and large multi-male multi-female groups for red-capped mangabeys) (Gautier-Hion and Gautier, 1978; Mitani, 1989; Matthews and Matthews, 2002; Lemasson et al, 2006; Mwenja, 2006; Ouattara et al, 2009b; Dolado and Beltran, 2012). We decided to focus on females as we expected the influence of social factors on vocal variability to be more striking in this sex class whose role in mediating intra-group relationships is predominant (Rowell, 1988).…”

Social factors play a key role in the structuring of vocal repertoires at the individual level, notably in non-human primates. Some authors suggested that, at the species level too, social life may have driven the evolution of communicative complexity, but this has rarely been empirically tested. Here, we use a comparative approach to address this issue. We investigated vocal variability, at both the call type and the repertoire levels, in three forest-dwelling species of Cercopithecinae presenting striking differences in their social systems, in terms of social organization as well as social structure. We collected female call recordings from twelve De Brazza's monkeys (Cercopithecus neglectus), six Campbell's monkeys (Cercopithecus campbelli) and seven red-capped mangabeys (Cercocebus torquatus) housed in similar conditions. First, we noted that the level of acoustic variability and individual distinctiveness found in several call types was related to their importance in social functioning. Contact calls, essential to intra-group cohesion, were the most individually distinctive regardless of the species, while threat calls were more structurally variable in mangabeys, the most “despotic” of our three species. Second, we found a parallel between the degree of complexity of the species' social structure and the size, diversity, and usage of its vocal repertoire. Mangabeys (most complex social structure) called twice as often as guenons and displayed the largest and most complex repertoire. De Brazza's monkeys (simplest social structure) displayed the smallest and simplest repertoire. Campbell's monkeys displayed an intermediate pattern. Providing evidence of higher levels of vocal variability in species presenting a more complex social system, our results are in line with the theory of a social-vocal coevolution of communicative abilities, opening new perspectives for comparative research on the evolution of communication systems in different animal taxa.

“…Moreover, we found no dominance or kinship effects on any of the facial expressions displayed, presumably in relation with the sociality of red-capped mangabeys, which have been shown to adopt both despotic and egalitarian behaviors (Dolado and Beltran 2012). Despite a steep hierarchy within their groups, red-capped mangabeys have indeed relatively dynamic dominance relationships (Dolado and Beltran 2011) with some propensity to counter-attack, as do tolerant macaque species (de Waal and Luttrell 1989;Thierry 2007).…”

“…Since mangabeys did repeat their gestures in the absence of their goal being reached, our hypothesis on communication persistence as a function of recipient’s responsiveness seems partially verified, and two explanations could account to explain that the number of begging gestures decreased with time. This could be due to a decrease in their motivation to communicate with a non-responsive recipient, or be related to the steep hierarchical social system of red-capped mangabeys 76 , in which requesting something for too long from a higher-ranking individual (as could be the experimenter) would be avoided.…”

Sensitivity to recipient’s attention and responsiveness are critical markers of intentional communication. Although previous research showed that ape gestures can be intentional, few studies have yet addressed this question concerning monkeys. Here, we characterise the effect of a recipient’s presence, attentional state and responsiveness on the interspecific gestural communication of captive red-capped mangabeys ( Cercocebus torquatus ). Previous reports showed that they produced learnt begging gestures towards a human recipient preferentially when the latter was facing them. We used here a novel setup that allows subjects to move around an experimenter and to use different modalities (visual and acoustic) to communicate. We found that when the recipient was not facing them, mangabeys moved to a position in the visual field of their recipient rather than using attention-getters. Interestingly, unlike apes, they did not elaborate their communication visually or acoustically when the experimenter did not respond favourably to their begging. However, our results may suggest that begging gestures were goal-directed, since mangabeys inhibited them when the experimenter was not available to answer immediately (i.e. give a reward). Overall, red-capped mangabeys’ interspecific visual communication presented intentionality features, but their use of begging gestures was less flexible than that of great apes in similar situations.
