Stability in biological systems requires evolved mechanisms that promote robustness. Cohesive primate social groups represent one example of a stable system, which persist spite frequent conflict. Multiple sources stability likely exist for any system and such robustness, or lack thereof, should be reflected thus detectable the group's network structure, at multiple levels. Here we show how structure group are linked to fundamental characteristics individual agents environmental contexts...
Studies of prosocial policing in nonhuman societies traditionally focus on impartial interventions because an underlying assumption that partial support implies a direct benefit to the intervener, thereby negating potential for being maintaining social stability group. However, certain types have significant be controlling conflict, e.g. non-kin subordinates. Here, we propose hypothesis some agonistic serve function maintains group stability. Using seven large captive groups rhesus macaques,...
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...
Background Although a wealth of literature points to the importance social factors on health, detailed understanding complex interplay between and biological systems is lacking. Social status one aspect life that made up multiple structural (humans: income, education; animals: mating system, dominance rank) relational components (perceived status, interactions). In nonhuman primate model we use novel network techniques decouple two rank (a commonly used measure in animal models) certainty...
The persistence of biological systems requires evolved mechanisms which promote stability. Cohesive primate social groups are one example stable systems, persist in spite regular conflict. We suggest that genetic relatedness and its associated kinship structure a potential source stability as is an important organizing principle many animal societies. investigated the effect average per matrilineal family on grooming agonistic interactions 48 matrilines from seven captive rhesus macaques....
Social stability in group-living animals is an emergent property which arises from the interaction amongst multiple behavioral networks. However, pinpointing when a social group at risk of collapse difficult. We used joint network modeling approach to examine interdependencies between two networks, aggression and status signaling, four stable three unstable groups rhesus macaques order identify characteristic patterns interdependence that are readily distinguishable groups. Our results...
We develop a three-step computing approach to explore hierarchical ranking network for society of captive rhesus macaques. The computed is sufficiently informative address the question: Is macaque more like kingdom or corporation? Our computations are based on approach. These steps devised deal with tremendous challenges stemming from transitivity dominance as necessary constraint relations among all individual macaques, and very high sampling heterogeneity in behavioral conflict data. first...
In social animals, group living may impact the risk of infectious disease acquisition in two ways. On one hand, connectedness puts individuals at greater or susceptibility for acquiring enteric pathogens via contact-mediated transmission. Yet conversely, strongly bonded societies like humans and some nonhuman primates, having close connections strong ties support can also socially buffer against transmissibility agents. Using network analyses, we assessed potentially competing roles...
The impact of anthropogenic environmental changes may impose strong pressures on the behavioral flexibility free-ranging animals. Here, we examine whether rates interactions with humans had both a direct and indirect influence duration distribution social grooming in commensal rhesus macaques (Macaca mulatta).Data were collected two locations city Shimla northern India: an urban setting temple area. We divided these series similar-sized physical blocks (N = 48) varying human-macaque...
Social relationships profoundly impact health in social species. Much of what we know regarding the affiliative on nonhuman primates (NHPs) has focused structure connections or quality relationships. These are often quantified by comparing different types behaviors ( e.g. , contact sitting, grooming, proximity) pooling into an overall measure affiliation. However, it is unclear how breadth many which ones) a dyad engages and fitness outcomes. We used novel network approach to quantify based...
Macaques live in close contact with humans across South and Southeast Asia, direct interaction is frequent. Aggressive a concern many locations, particularly among populations of rhesus longtail macaques that co-inhabit urbanized cities towns humans. We investigated the proximate factors influencing occurrence macaque aggression toward as well human to determine extent which behavior elicits vice versa. conducted 3-month study four free-ranging Dehradun, India from October-December 2012,...
Humans live in societies full of rich, complex relationships that influence health. The ability to improve human health requires a detailed understanding the interplay biological systems contributing disease processes including mechanisms underlying social contexts on these systems. Approaches empirically recognize inherent complexity life are therefore critical, and should be applied over span. A longitudinal computational science approach provides methods uniquely suited elucidate by which...
Abstract Despite increasing conflict at human–wildlife interfaces, there exists little research on how the attributes and behavior of individual wild animals may influence interactions. Adopting a comparative approach, we examined impact animals’ life-history social interactions between humans (peri)urban macaques in Asia. For 10 groups rhesus, long-tailed, bonnet macaques, collected behavior, spatial data, human–interaction data for 11–20 months pre-identified individuals. Mixed-model...
Abstract The signaling context has been found to change the meaning of silent bared‐teeth display (SBT) in pigtail macaques ( Macaca nemestrina ) such that SBT apparently peaceful contexts communicates subordination, a long‐term pattern behavior, whereas conflict it immediate submission PNAS , 104: 1581–1586). However, dependent nature not yet explored other species. We investigated usage with respect grooming, severe aggression, and signaler‐receiver sex, rank difference, body size seven...
Abstract In the wild, male rhesus macaques disperse at sexual maturity. captivity, however, males cannot from their natal groups. Thus, presence of in captive social groups is unnatural and has potential to negatively influence group dynamics stability. A primary difference between non‐natal (immigrant) that have opportunity form long‐term alliances with maternal kin as well nonkin. We investigated factors associated males' impact these on measures behavior, dynamics, found more frequently...
Abstract How the captive environment influences behavior of animals is relevant to well‐being animals. Captivity diverges from natural in many ways, and one goal enrichment practices encourage species‐typical these unnatural environments.

Groups having spent a greater proportion their time...
In a complex behavioral system, such as an animal society, the dynamics of system whole represent synergistic interaction among multiple aspects society. We constructed single-behavior social networks for purpose approximating from single interest: rhesus macaque Instead analyzing these individually, we describe new method jointly them in order to gain comprehensive understanding about whole. This modeling becomes valuable analytical tool studying nature any system. Here develop bottom-up,...
