“…The social integration estimate then is an offset from the population average. In general, our social integration measures are similar to nodal in- and out-degree centrality in the social networks tradition (Hasenjager and Dugatkin, 2015).…”

Across multiple species of social mammals, evidence is accumulating that sociality is associated with fitness. In long-lived species, like primates, lifespan is one of the main fitness components. Here, we provide the first direct evidence that females who provide more in social services live longer. We used 18 years of data from the Lomas Barbudal Monkey project to quantify sociality in 11 capuchin (Cebus capucinus) social groups using three interaction types: grooming, support in coalitionary aggression, and foraging in close proximity. We analyzed each domain separately to understand how giving and receiving social favors impact survivorship. To estimate female sociality in each of these domains, we built an adaptation of the Social Relations Model. This approach enabled us to estimate individual rates of giving and receiving interactions and take into account the uncertainty in these estimates due to varying amounts of observations of each individual. Subsequently, we modeled adult females’ survival as a function of their sociality estimate, rank, age, group size, and maternal kin presence using a Bayesian Cox proportional hazards model. We found that females who provide more grooming to other group members survive longer. There was no strong evidence that females who receive more grooming, participate more often in coalitionary aggression, and forage more often in close proximity of others also have higher survivorship. These results add a neotropical primate species to the growing list of mammals, including humans, where greater sociality is associated with longevity.

Social interactions, through influence on behavioural processes, can play an important role in populations’ resilience (i.e. ability to cope with perturbations). However little is known about the effects of perturbations on the strength of social cohesion in wild populations. Long-term associations between individuals may reflect the existence of social cohesion for seizing the evolutionary advantages of social living. We explore the existence of social cohesion and its dynamics under perturbations by analysing long-term social associations, in a colonial seabird, the Audouin’s gull Larus audouinii, living in a site experiencing a shift to a perturbed regime. Our goals were namely (1) to uncover the occurrence of long-term social ties (i.e. associations) between individuals and (2) to examine whether the perturbation regime affected this form of social cohesion. We analysed a dataset of more than 3500 individuals from 25 years of monitoring by means of contingency tables and within the Social Network Analysis framework. We showed that associations between individuals are not only due to philopatry or random gregariousness but that there are social ties between individuals over the years. Furthermore, social cohesion decreased under the perturbation regime. We sustain that perturbations may lead not only to changes in individuals’ behaviour and fitness but also to a change in populations’ social cohesion. The consequences of decreasing social cohesion are still not well understood, but they can be critical for the population dynamics of social species.
