“…Our study expands on former research in this field in terms of its scale, both temporally and in the range of behaviours examined, in a wild population, demonstrating that social phenotypes are a phenomenon in long-lived species occupying complex social environments. Indeed, given the results of our study and work conducted in taxa ranging from insects (23) to fish (24,25) to birds (19) to primates (20,89), consistent individual differences in social phenotypes seem the norm for group-living animals regardless of the degree of social complexity.…”

“…Importantly, we found consistent individual differences in multiple forms of social interaction. Much research to date on social phenotypes has focused solely on association patterns (19,25), or on single forms of dyadic interaction (20, 34), with a minority of studies examining consistency in multiple forms of social behaviours (89,98,99). Our study shows that consistent individual differences in social behaviour extends to patterns of aggression and affiliation, both of which should influence fitness more than association alone (43,44,85–88,100).…”

31Animals living in social groups navigate challenges when competing and cooperating with other group 32 members. Changes in demographics, dominance hierarchies or ecological factors, such as food 33 availability or disease prevalence, are expected to influence decision-making processes regarding social 34interactions. Therefore, it could be expected individuals show flexibility in social behaviour over time to 35 maximise the fitness benefits of social living. To date, research across species has shown that stable 36inter-individual differences in social behaviour exist, but mostly over relatively short data collection time 37periods. Using data spanning over 20 years, we demonstrate that multiple social behaviours are 38 repeatable over the long-term in wild chimpanzees, a long-lived species occupying a complex fission-39 fusion society. We controlled for temporal, ecological and demographic changes, limiting pseudo-40repeatability. We conclude that chimpanzees living in natural ecological settings have relatively stable 41 long-term social phenotypes over years that may be independent of life history stage or strategies. Our 42 results add to the growing body of literature suggesting consistent individual differences in social 43 tendencies are more likely the rule rather than the exception in group-living animals. 44 45

“…As urbanization is occurring at a rapid rate, it is important to consider how the behavior and stability of natural animal social groups are impacted by urban living. However, few studies have considered how social groups and behaviors may vary with differing environmental conditions (Belton, Cameron, & Dalerum, ; Blaszczyk, ; Stanley & Dunbar, ), and only two studies have considered how disturbances to the environment may influence the stability of networks (Formica, Wood, Cook, & Brodie, ; Krause et al, ). In this study, we provide the first assessment, to our knowledge, of variation in the characteristics and consistency of group foraging behaviors and temporal stability of individual social network position in wild urban and rural groups.…”

Urbanization and the temporal patterns of social networks and group foraging behaviors

Urbanization causes dramatic and rapid changes to natural environments, which can lead the animals inhabiting these habitats to adjust their behavioral responses. For social animals, urbanized environments may alter group social dynamics through modification of the external environment (e.g., resource distribution). This might lead to changes in how individuals associate or engage in group behaviors, which could alter the stability and characteristics of social groups. However, the potential impacts of urban habitat use, and of habitat characteristics in general, on the nature and stability of social associations remain poorly understood. Here, we quantify social networks and dynamics of group foraging behaviors of black‐capped chickadees ( N = 82, Poecile atricapillus ), at four urban and four rural sites weekly throughout the nonbreeding season using feeders with radio frequency identification of individual birds. Because anthropogenic food sources in urban habitats (e.g., bird feeders) provide abundant and reliable resources, we predicted that social foraging associations may be of less value in urban groups, and thus would be less consistent than in rural groups. Additionally, decreased variability of food resources in urban habitats could lead to more predictable foraging patterns (group size, foraging duration, and the distribution of foraging events) in contrast to rural habitats. Networks were found to be highly consistent through time in both urban and rural habitats. No significant difference was found in the temporal clumping of foraging events between habitats. However, as predicted, the repeatability of the clumping of foraging events in time was significantly higher in urban than rural habitats. Our results suggest that individuals living in urban areas have more consistent foraging behaviors throughout the nonbreeding season, whereas rural individuals adjust their tactics due to less predictable foraging conditions. This first examination of habitat‐related differences in the characteristics and consistency of social networks along an urbanization gradient suggests that anthropic habitat use results in subtle modifications in social foraging patterns. Future studies should examine potential implications of these differences for variation in predation risk, energy intake, and information flow.

“…In turn, the dynamics of social networks commonly affect individual fitness (survival or reproductive success) and can also influence ecological and evolutionary processes at the population level (Croft, James, & Krause, ; Kurvers, Krause, Croft, Wilson, & Wolf, ; Montiglio, McGlothlin, & Farine, ; Wey, Blumstein, Shen, & Jordán, ). Although several studies have focused on temporal changes in social networks (Bar Ziv et al, ; Blaszczyk, ; Maldonado‐Chaparro, Hubbard, & Blumstein, ; VanderWaal, Atwill, Isbell, & McCowan, ), most studies have utilized association networks based on physical contact, spatial proximity, or co‐occurrence. To date, only a small number of studies have focused on vocal networks in animal populations (Fernandez, Vignal, & Soula, ; Kulahci, Ghazanfar, & Rubenstein, ; Kulahci, Rubenstein, & Ghazanfar, ; Snijders & Naguib, ).…”

Vocal networks remain stable after a disturbance in Emei music frogs

Social network analysis has been widely used to investigate the dynamics of social interactions and the evolution of social complexity across a range of taxa. Anuran species are highly dependent on vocal communication in mate choice; however, these species have rarely been the subject of social network analysis. The present study used social network analysis to investigate whether vocal network structures are consistent in Emei music frog (Babina daunchina) after the introduction of a simulated exotic rival of varying competitiveness into the social group. We broadcasted six categories of artificial calls (either highly sexually attractive calls produced from inside male nests or calls of low sexual attractiveness produced outside nests with three, five or seven notes, respectively) to simulate an intruder with different levels of competitiveness. We then constructed vocal networks for two time periods (before and after the disturbance) and quantified three network metrics (strength, closeness, and betweenness) that measure different aspects of individual‐level position. We used the mean values of these network metrics to evaluate group‐level changes in network structure. We found that the mean strength, mean closeness and mean betweenness were consistent between two time periods in all ponds, despite the fact that the positions of some individuals had changed markedly after disturbance. In addition, there was no significant interaction effect between period and numbers of notes on the three network metrics. These finding suggest that the structure of vocal networks in Emei music frogs remain stable at the group level after a conspecific disturbance, regardless of the intruder's competitiveness.
