Contemporary evolutionary theories propose that living in groups drives the selection of enhanced cognitive skills to face competition and facilitate cooperation between individuals. Being able coordinate both space time with others make strategic decisions are essential for cooperating within groups. Social tolerance an egalitarian social structure have been proposed as one specific driver cooperation. Therefore, is predicted be associated underpin communication coordination. should also...
Among nonhuman primates, the evolutionary underpinnings of variation in social structure remain debated, with both ancestral relationships and adaptation to current conditions hypothesized play determining roles. Here we assess whether interspecific higher-order aspects female macaque (genus: Macaca) dominance grooming show phylogenetic signals, that is, greater similarity among more closely-related species. We use a network approach describe characteristics structure, based on direct...
Why regularities in personality can be described with particular dimensions is a basic question differential psychology. Nonhuman primates also characterized terms of structure. Comparative approaches help reveal phylogenetic constraints and social ecological patterns associated the presence or absence specific dimensions. We sought to determine how different structures are related interspecific variation style. Specifically, we examined this 6 species macaques, because macaque style well...
While there is no consensus about the definition of complexity, it widely accepted that ability to produce uncertainty most prominent characteristic complex systems. We introduce new metrics purport quantify complexity living organisms and social organizations based on their levels uncertainty. consider three major dimensions regarding complexity: diversity number system elements categories these elements; flexibility which bears upon variations in combinability refers patterns connection...
We tested the social complexity hypothesis which posits that animals living in complex environments should use communication systems. focused on two components of vocal complexity: diversity (number categories calls) and flexibility (degree gradation between calls). compared acoustic structure signals groups macaques belonging to four species with varying levels uncertainty (i.e. complexity) tolerance (the higher degree tolerance, uncertainty): intolerant species, Japanese rhesus macaques,...
There is a vast and ever-accumulating amount of behavioural data on individually recognised animals, an incredible resource to shed light the ecological evolutionary drivers variation in animal behaviour. Yet, full potential such lies comparative research across taxa with distinct life histories ecologies. Substantial challenges impede systematic comparisons, one which lack persistent, accessible standardised databases. Big-team approaches building databases offer solution facilitating...
Abstract In nonhuman primate social groups, dominance ranks are usually assigned to individuals based on outcomes of dyadic agonistic encounters. Multiple approaches have been used, but currently there is no consensus. One approach, David's Scores (DS), offers dual advantages yielding cardinal scores that may in turn be used compute hierarchical steepness. Here we correlate rank orders yielded by DS with those both the traditionally I&SI approach and recently proposed parametric Bayesian...
Males living in multi-male groups are both strong rivals and potential allies. In several primate species they regularly interact through ritualized exchanges known as greetings. We studied five captive of Tonkean macaques (Macaca tonkeana) to test hypotheses regarding the social function found that greetings were mostly reciprocal interactions, often involved physical contact facial displays. Although initiated by higher-ranking individual each dyad, subordinates could initiate...
Celebrations and bursts of communal joy can occur spontaneously in human communities based on mechanisms emotional contagion. Some examples similar collective excitement have been reported animals when they reunite or anticipate rewards, but little is known about the processes meaning these multiple interactions. We experimentally studied such arousals two captive groups Tonkean macaques (Macaca tonkeana) within context reunions following temporary separation subgroups. compared behaviors...
Facial displays are important for communication, and their ontogeny has been studied primarily in chimpanzees macaques. We investigated the ontogeny, communicative function target of facial Cebus apella . Our results show that absent at birth develop as infants grow older. Lip-smacking appears first (at about 1 month age), followed by scalp-lifting, relaxed open-mouth, silent bared-teeth, open-mouth bared-teeth finally threat face. Infants perform most same contexts adults, with exception...
Whereas most experiments indicate that monkeys have no theory of mind, a study carried out by Wood and collaborators (2007) claimed they can make inferences about the intentions another individual. We applied experimental procedure devised these authors to investigate whether recognize goal-directed actions. tested 16 Tonkean macaques (Macaca tonkeana) 12 tufted capuchin (Sapajus apella). Each subject was submitted 24 trials in randomized order. The experimenter presented 2 containers, 1...
It was long assumed that only humans can distinguish the living from dead. Renewed interest in this question over last decade has led several authors to assert non-human primates are also aware of death. We investigate issue by comparing behaviours monkeys and great apes toward helpless conspecifics, basing our analysis on published reports. first examine mothers towards body their dead offspring. They may carry corpse for days or more before abandoning it. groom, inspect protect it,...
Abstract The theory of sexual selection predicts that females should be discriminatory in the choice partners. Females can express their two ways. In direct mate choice, they show preferences for certain indirect select partners by displaying sexually attractive traits, thus eliciting contest competition between males. We focused on a primate species which advertise timing ovulation and studied balance these strategies. tested predictions related to three hypotheses about female namely...
Many studies investigate the decisions made by animals focusing on their attitudes toward risk, that is, risk-seeking, risk neutrality, or aversion. However, little attention has been paid to extent which individuals understand different odds of outcomes. In a previous gambling task involving 18 lotteries (Pelé, Broihanne, Thierry, Call, & Dufour, 2014), nonhuman primates used probabilities gains and losses make decision. Although use complex mathematical calculation for decision-making...
Decision outcomes in unpredictable environments may not have exact known probabilities. Yet the predictability level of matters decisions, and animals, including humans, generally avoid ambiguous options. Managing ambiguity be more challenging requires stronger cognitive skills than decision-making under risk, where decisions involve Here we compare capuchins, macaques, orangutans, gorillas, chimpanzees bonobos risky contexts. Subjects were shown lotteries (a tray potential rewards, some...
Abstract The investigation of vocal similarity between individuals has provided evidence the flexibility communication signals. This study evaluates impact group membership, affiliative bonds, kinship and dominance on acoustic in two primate species with different social styles, intolerant rhesus macaques tolerant Tonkean macaques. We focused fundamental frequencies contact calls emitted by adult females. Close promoted both species, also membership macaques, indicating involvement...
