“…Overall, the SAOM framework enables to study how individuals change their relationships in response to the present network structure, i.e., group behavior (29). Despite its strong potential, SAOMs have been less explored in animal studies compared to social sciences studies [barbary macaques: (26); black-capped chickadees: (30); bottlenose dolphins: (31); crickets: (27,32); farmed salmons: (33); fruit flies: (34); rooks: (35); spiders: (36); spotted hyenas: (24); vervet monkeys: (37)].…”

Understanding Allogrooming Through a Dynamic Social Network Approach: An Example in a Group of Dairy Cows

For gregarious species such as domestic cattle, the social environment is a very important determinant of their welfare and fitness. Understanding the complexity of cows' relationships can assist the development of management practices that are more integrated with the cows' social behavioral processes. The two aims of this study were: (1) to determine the dynamics of affiliative relationships, as indicated by allogrooming, by means of stochastic actor-oriented modeling, in dairy cows during early lactation; (2) to explore the underlying processes and the individual attributes, such as age, social rank and reproductive state, that could shape network pattern changes in grooming contacts between individual. We observed the allogrooming behavior of a dynamic group of 38 dairy cows for 4 h per day for 30 days. Using stochastic actor-oriented models, we modeled the dynamics of weekly contacts and studied how structural processes (e.g., reciprocity, transitivity, or popularity) and individual attributes (i.e., age, social rank, and reproductive state) influence network changes. We found that cows tended to groom individuals that had previously groomed them, implying a possible cooperation. Cows that groomed more actively did not appear to have a preference for specific individuals in the herd, and in return, tended to be groomed by fewer cows over time. Older individuals groomed more cows than younger ones, indicating that allogrooming could be related to seniority. Cows groomed mainly individuals of similar age, suggesting that familiarity and growing up together enhanced social grooming. Over time, cows with higher social rank were groomed by fewer cows and individuals recently reintroduced to the group groomed more herdmates. The study of social network dynamics can be used to better understand the complexity and non-linearity of cow relationships. Our findings, along with further research, can complement and strengthen the design of improved management practices that are more in line with the natural social behavior of cows.

“…Aggression is common in field crickets of the subfamily Gryllinae. It takes the form of several distinct behaviours that have been almost exclusively studied in male–male encounters: aggressive calling, antennal interaction, charging, mandibular contact and sparring (Alexander, 1961 ; Bailey & French, 2012 ; Bertram et al, 2011 ; Bunting & Hedrick, 2018 ; Fisher et al, 2019 ; Fuentes & Shaw, 1986 ; Hedrick & Bunting, 2014 ; Logue et al, 2010 ). Given that it is known to be adaptive in some contexts but thought to incur large fitness costs (Judge & Bonanno, 2008 ; Kuriwada, 2017 ), we were particularly interested in how previous patterns of intrasexual aggression related to male mating success.…”

Intrasexual aggression reduces mating success in field crickets

Aggressive behaviour is thought to have significant consequences for fitness, sexual selection and the evolution of social interactions, but studies measuring its expression across successive encounters—both intra‐ and intersexual—are limited. We used the field cricket Teleogryllus oceanicus to evaluate factors affecting repeatability of male aggression and its association with mating success. We quantified focal male aggression expressed towards partners and received from partners in three successive, paired trials, each involving a different male partner. We then measured a proxy of focal male fitness in mating trials with females. The likelihood and extent of aggressive behaviour varied across trials, but repeatability was negligible, and we found no evidence that patterns of focal aggression resulted from interacting partner identity or prior experience. Males who consistently experienced aggression in previous trials showed decreased male mating ‘efficiency’—determined by the number of females a male encountered before successfully mating, but the effect was weak and we found no other evidence that intrasexual aggression was associated with later mating success. During mating trials, however, we observed unexpected male aggression towards females, and this was associated with markedly decreased male mating efficiency and success. Our findings suggest that nonadaptive aggressive spillover in intersexual mating contexts could be an important but underappreciated factor influencing the evolution of intrasexual aggression.

“…Such social interactions can range from mating to agonistic. A common aspect of animal social networks is skewness in the number of interactions individuals have, with some individuals having many interactions while others have few (Fisher et al 2019;Krause et al 2015). More or few social interactions may have associated benefits or costs for an individual (Koto et al 2023;Ruan & Wu 2008;Snyder-Mackler et al 2020).…”

Social interactions are prevalent in animals, with some individuals participating in more interactions than others. However, the mechanisms underlying this heterogeneity in social interaction frequency and its potential fitness consequences remain poorly characterized. Here, we examine the effects of non-nutritive plant metabolites (‘clerodanoids’) on social networks and lifespan in the turnip sawfly. The adult sawflies facultatively acquire clerodanoids from non-host plant species. We found high variation in clerodanoid amounts in both wild-caught and lab-reared individuals. Furthermore, sawflies could acquire clerodanoids by nibbling on conspecifics that had prior access to these metabolites, with asymmetric clerodanoid access leading to increased agonistic interactions. Network analysis revealed more social interactions in sawfly groups where some or all individuals had prior access to clerodanoids, while groups with no prior access had fewer interactions. The number of social interactions depended on the clerodanoid status of the focal individual and also of other conspecifics. Finally, we observed a shorter lifespan in adults with prior clerodanoid access when paired with individuals without prior access, suggesting that social interactions to obtain clerodanoids have fitness costs. Our findings demonstrate that individual variation in non-nutritional sequestered plant metabolites can skew social interactions, with potential fitness implications that impact individual social niches.
