Renewed interest in fission‐fusion dynamics is due to the recognition that such may create unique challenges for social interaction and distinctive selective pressures acting on underlying communicative cognitive abilities. New frameworks integrating current knowledge emerge from a fundamental rethinking of term “fission‐fusion” away its general use as label particular modal type system (i.e., “fission‐fusion societies”). Specifically, because degree spatial temporal cohesion group members...
Significance Although scientists have identified surprising cognitive flexibility in animals and potentially unique features of human psychology, we know less about the selective forces that favor evolution, or proximate biological mechanisms underlying this process. We tested 36 species two problem-solving tasks measuring self-control evaluated leading hypotheses regarding how why cognition evolves. Across species, differences absolute (not relative) brain volume best predicted performance...
Abstract Drought‐related tree mortality is now a widespread phenomenon predicted to increase in magnitude with climate change. However, the patterns of which species and trees are most vulnerable drought, underlying mechanisms have remained elusive, part due lack relevant data difficulty predicting location catastrophic drought years advance. We used long‐term demographic records extensive databases functional traits distribution understand responses 20–53 an extreme seasonally dry tropical...
Heart rate telemetry was explored as a means to access animal emotion during social interactions under naturalistic conditions. rates of 2 middle-ranking adult females living in large group rhesus macaques (Macaca mulatta) were recorded along with their behavior. changes types investigated, while controlling for the effects posture and activity. The risk aggression associated approach dominant individual expected provoke anxiety approachee. This prediction supported by heart increase after...
Consolation, i.e., postconflict affiliative interaction directed from a third party to the recipient of aggression, is assumed have stress-alleviating function. This function, however, has never been demonstrated. study shows that consolation in chimpanzees reduces behavioral measures stress recipients aggression. Furthermore, was more likely occur absence reconciliation, between former opponents. Consolation therefore may act as an alternative reconciliation when latter does not occur. In...
Abstract We studied the occurrence of social interactions characterizing post‐conflict situations in a group long‐tailed macaques. Victims agonistic conflicts showed reconciliation: they had more affiliative contacts with former aggressor after conflict than control periods. There was no evidence for consolation: victims did not contact other groups members aggressor, or specific subsets members, earlier exchange either their own kin aggressor's during Even though time spent allogrooming...
After an agonistic conflict between two animals, they may exchange affiliative social contacts. The function of this reconciliation behavior is thought to be the repair relationship opponents. We examined hypothesis that socially effective because it also lead a reduction victim's acute stress. Reconciliation was studied in well-established captive group long-tailed macaques (Macaca fascicularis). victim 10 min period after end interaction recorded and compared with control observation made...
Sociality exists in an extraordinary range of ecological settings. For individuals to accrue the benefits associated with social interactions, they are required maintain a degree spatial and temporal coordination their activities, make collective decisions. Such decision‐making has been focus much recent research. However, efforts largely have directed toward understanding patterns behaviour relatively stable cohesive groups. Less well understood is how fission–fusion dynamics mediate...
Raids into neighboring territories may occur for different reasons, including the increase of foraging and mating opportunities directly or indirectly through killing rivals. Lethal raids have been mainly observed in humans chimpanzees, with raiding males being reported to search purposefully neighbors. Here we report on first cases ever witnessed parties male spider monkeys, a species expected show such behavioral tendency, given its similarity chimpanzees critical socio-ecological...
The strategies used by individuals to deploy altruistic behaviors have long captured research attention. Two general mechanisms can account for the decision-making process underpinning deployment of among nonkin. first mechanism, referred here as "temporal relation between events," corresponds classical reciprocal altruism; such, it is strictly within-dyad and has a strong temporal component. second labeled "partner choice based on benefits received," relies across-dyad comparisons. Although...
Seyfarth's model assumes that female primates derive rank-related benefits from higher-ranking females in exchange for grooming. As a consequence, the predicts prefer high-ranking as grooming partners and compete opportunity to groom them. Therefore, allogrooming is expected be directed up dominance hierarchy occur more often between with adjacent ranks. Although data Old World generally support model, studies on relation rank New genus Cebus have found conflicting results, showing...
We argue that the study of social complexity can follow two different approaches, based on how it is seen from outside or experienced within. Recent focus has been former with emerging interactions group members. Here, we take view within and deal individual members may experience, exploring arising aspects structure organization. review a variety sources in terms variation between relationships, opportunities to interact members, role third parties. then examine individuals cope they face....
Abstract Conservation funding is currently limited; cost‐effective conservation solutions are essential. We suggest that the thousands of field stations worldwide can play key roles at frontline biodiversity and have high intrinsic value. assessed stations’ return on investment explored impact COVID‐19. surveyed leaders across tropical regions host primate research; 157 in 56 countries responded. Respondents reported improved habitat quality reduced hunting rates over 80% lower operational...
