“…In catarrhine monkeys with female philopatry such as vervet monkeys, females are more central than males in affiliative and proximity networks (e.g., Blaszczyk, 2018; Jarrett et al, 2018; Lehmann & Ross, 2011; Sosa, 2016). High‐ranked individuals are usually more aggressive and groomed more than others, which increases their centrality in affiliative and aggression networks (e.g., Blaszczyk, 2018; Borgeaud et al, 2017; macaques: Wooddell et al, 2019). Ontogeny may also affect individuals' network position (Borgeaud et al, 2016, 2017).…”

Previous primate social network studies largely limited their focus to grooming and/or aggression networks, particularly among adult females. In addition, the consistency of individuals' network centrality across time and/or different networks has received little attention, despite this being critical for a global understanding of dynamic social structure. Here, we analyzed the grooming, aggression, and play social networks of a group of 26-28 wild vervet monkeys (Chlorocebus pygerythrus), including adults and juveniles, over two periods of 6 months. We collected data on grooming, play, and aggression using focal animal sampling with instantaneous recording and ad libitum sampling. We examined whether individuals' network centralities were consistent over the two periods and across networks, as well as the effect of age, sex, and dominance rank on three individual centrality metrics in each network and within each study period. We found that individuals were quite consistent in their network position from 1 year to the next despite changes in group composition. However, their network centralities were not correlated across networks, except for Strength and weighted Eigenvector centrality between grooming and aggression networks. We also found that in the aggression network, highrankers showed the highest centrality in most network metrics (e.g., Degree, Strength, and Eigenvector centrality) and compared to males, females were most central in 2017 but not in 2018. In the grooming network, high-ranking females had the highest Eigenvector centrality, whereas in the play network, juvenile males had the highest Eigenvector centrality. Our findings corroborate previous findings on vervet monkeys. In addition, they show that individuals' network centralities may vary among networks and over time; thus highlighting the effect of sociodemographics and behaviors' functions on the group level dynamics of social behavior.

Remarkably, at the planation edge, this relationship was reversed, possibly because high-and low-ranking females may use different strategies to handle the potentially stressful environment and intense feeding competition posed by the plantation.…”

Human-induced habitat alterations globally threaten animal populations, often evoking complex behavioural responses in wildlife. This may be particularly dramatic when negatively affecting social behaviour, which fundamentally determines individual fitness and offspring survival in group-living animals. Here, we provide first evidence for critical behavioural modifications in sociality of Southern pig-tailed macaques visiting Malaysian oil palm plantations in search of food. Specifically, we found significant reductions of positive social interactions, an increase of aggression and shifts in the macaques' social network structure, with the central positions of high-ranking adult females and immatures being passed to low-ranking individuals, likely resulting from socio-ecological risks posed by plantations. Deviations from natural behaviour also affected the smallest but crucial social units within groups, mother-infant pairs, with increased maternal protectiveness at plantations. We suggest that although primates can persist in human-altered habitats, their ability to adapt comes with a trade-off for their natural sociality, potentially hampering infant development and individual survival. Studies like ours remain critical for understanding species’ adaptability to anthropogenic landscapes, which may ultimately contribute to facilitating their coexistence with humans and preserving biodiversity.

“…This numerical system tracks rank changes over time by constantly updating values according to wins and losses. We rely on Elo-ratings computed for adult female monkeys from >4,000 dominance interactions in 30-min observation sessions between 2013 and 2016, following previously established methods (Wooddell et al, 2016(Wooddell et al, , 2017aWooddell, Kaburu, and Dettmer, 2019).…”

Intergenerational Effects of Early-Life Advantage: Lessons from a Primate Study

This paper uses three decades of studies with Rhesus monkeys to investigate the intergenerational effects of early life advantage. Monkeys and their offspring were both randomly assigned to be reared together or apart from their mothers. We document significant intergenerational effects of maternal presence. We also estimate, for the first time, the intergenerational complementarity of early life advantage, where the intergenerational effects of maternal rearing are only present for offspring that were mother-reared. This finding suggests that parenting is the primary mechanism driving the intergenerational effects. Our paper demonstrates how studies of primates can inform human development.
