“…In male junglefowl, winner and loser effects appear to have only a weak influence on dominance hierarchy formation, whereas genetic or developmental variation in aggressiveness is more important and shows consistency over time (Favati et al 2017(Favati et al , 2021Pizzari and McDonald 2019). These observations would agree with our results, provided that the distribution of acquired resources has roughly a linear shape.…”

Social hierarchies can increase reproductive skew in group-living animals. Using game theory we investigate how the opportunity for differently ranked individuals to acquire resources influences reproductive skew, costs of hierarchy formation, and winner and loser effects. Individuals adjust their aggressive and submissive behaviour through reinforcement learning. The learning is based on perceived rewards and penalties, which depend on relative fighting ability. From individual-based simulations we determine evolutionary equilibria of traits that control an individual's learning. We examine situations that differ in the extent of monopolisation of contested resources by dominants and in the amounts of uncontested resources that are distributed independently of rank. With costly fighting, we find that stable dominance hierarchies form, such that reproductive skew mirrors the distribution of resources over ranks. Individuals pay substantial costs of interacting, in particular in high-skew situations, with the highest costs paid by intermediately ranked individuals. For cases where dominants monopolise contested resources there are notable winner and loser effects, with winner effects for high ranks and very pronounced loser effects for lower ranks. The effects are instead weak when acquired resources increase linearly with rank. We compare our results on contest costs and winner-loser effects with field and experimental observations.

“…Although a wealth of literature has demonstrated how disparities in size can determine the outcome of agonistic interactions and therefore represent good proxies for RHP ( Briffa 2008 , 2013 ; Chamorro-Florescano et al 2011 ) it is by no means the only or the most important RHP determinant. Factors including skill ( Briffa and Lane 2017 ), aggression ( Favati et al 2021 ), physiological traits ( Briffa and Sneddon 2007 ), and personality ( Rudin and Briffa 2012 ) can all contribute to an individual’s RHP. Furthermore, some of these RHP components can vary significantly between the sexes and independently of size, as is the case for aggression in stalk-eyed flies ( Teleopsis dalmanni : Bubak et al 2016 ; Bubak et al 2019 ).…”

Fighting over defense chemicals disrupts mating behavior

Studies on intraspecific contest behavior predominantly focus on contests between individuals of the same sex, however contest behavior is also expected to occur between individuals of the opposite sex including possible mates. Here we investigate potential trade-offs between mating and fighting behavior in the turnip sawfly (Athalia rosae). Adults of this species collect chemical defense compounds (clerodanoids) directly from plants but also indirectly by nibbling on conspecifics that have already obtained clerodanoids, a highly aggressive behavioral interaction. An A. rosae individual without clerodanoids may therefore be the potential mate or attacker of an individual of the opposite sex that has gained clerodanoids. To test the effect of clerodanoids on agonistic and mating behavior we paired females and males with or without clerodanoid access in a two-way factorial design. We show that asymmetrical clerodanoid acquisition between female-male pairs causes an increase in agonistic nibbling behavior, irrespective of sex, and moreover that conflict between individuals delays mating behavior. Our study highlights the importance of investigating agonistic intersex interactions, which can occur when adults are able to acquire valuable non-reproductive resources from a potential partner.

“…Despite the well-documented effects of social isolation across taxa ( Gerall et al 1967 ; Kim and Ehrman 1998 ; Cacioppo and Hawkley 2009 ), prior studies that experimentally manipulate social experience largely assess its influence using simple mating and behavioral assays on either individual behavior or dyadic interactions ( Sakata et al 2002 ; Arnold and Taborsky 2010 ; Guevara-Fiore 2012 ; Řežucha and Reichard 2014 ; Lehtonen et al 2016 ; Favati et al 2021 ). While highly informative, these approaches do not reflect the full range of social and environmental pressures that most animals face under natural settings.…”

Living in groups can provide essential experience that improves sexual performance and reproductive success. While the effects of social experience have drawn considerable scientific interest, commonly used behavioural assays often do not capture the dynamic nature of interactions within a social group. Here, we conducted three experiments using a social network framework to test whether social experience during early adulthood improves the sexual competence of bed bugs (Cimex lectularius) when placed in a complex and competitive group environment. In each experiment, we observed replicate groups of bed bugs comprising previously socialized and previously isolated individuals of the same sex, along with an equal number of standardized individuals of the opposite sex. Regardless of whether we controlled for their insemination history, previously isolated males mounted and inseminated females at significantly higher rates than previously socialized males. However, we found no evidence of social experience influencing our other measures of sexual competence: proportion of mounts directed at females, ability to overcome female resistance, and strength of opposite-sex social associations. We similarly did not detect effects of social experience on our female sexual competence metrics: propensity to avoid mounts, rate of successfully avoiding mounts, opposite-sex social association strength, and rate of receiving inseminations. Our findings indicate that early social experience does not improve sexual competence in male and female bed bugs.
