“…Whether dyads were all-flatwing, all-normal-wing, or a mix had no apparent bearing on the likelihood that SSB would be expressed. These findings support the view that expression of SSB is influenced primarily by behaviour of the individual expressing it, rather than appearance or signalling of the male conspecific (Han, et al, 2016), and is consistent with interpretations of SSB as a spillover of ordinary courtship behaviour into a non-adaptive context Zuk, 2009, Logue et al, 2009), i.e. a behavioural syndrome (Sih, Bell, & Johnson, 2004;Boutin et al, 2016).…”

“…Recent studies have tested various adaptive and non-adaptive explanations offered for the evolutionary origins and persistence of these behaviours. These have provided some support for non-adaptive hypotheses of SSB resulting from mistaken identity (Harari, Brockmann, & Landolt, 2000;Sales et al, 2018), with influences of social environment (Bailey and French, 2012;Han and Brooks, 2015;Han, Santostefano, & Dingemanse, 2016) and mating system (MacFarlane, Blomberg, Kaplan, & Rogers, 2007). However, SSB might also play important roles in mediating male competition (Lane, Haughan, Evans, Tregenza, & House 2016;Kuriwada 2017) and increasing relative fitness under sexual selection of males that express it (McRobert and Tompkins, 1988;Steiner, Steidle, & Ruther, 2005;Preston-Mafham, 2006;Bierbach, Jung, Hornung, Streit, & Plath, 2013).…”

Male same-sex sexual behaviour (SSB), where males court or attempt to mate with other males, is common among animal taxa. Recent studies have examined its fitness costs and benefits in attempts to understand its evolutionary maintenance, but the evolutionary consequences of SSB are less commonly considered. One potential impact of SSB might be to facilitate the evolution of traits associated with less sexually dimorphic males, such as alternative reproductive tactics, by diverting costly aggression from other males. To test this, we capitalised on the recent rapid spread of a silent male morph of field cricket, Teleogryllus oceanicus, which is unable to produce characteristic male acoustic signals, benefits from satellite mating behaviour, and exhibits feminised appearance and cuticular hydrocarbon profiles. We tested the prediction that interactions involving these non-signalling, less sexually dimorphic male morphs would show heightened rates of SSB, which could reduce the strength of male-male competition and permit greater access to females. We found no evidence that SSB was more common in trials involving silent males. Instead, SSB was predicted by courtship of females presented during a pre-trial treatment. Our results provide evidence supporting the view that SSB represents a spillover of sexually selected courtship behaviour in a non-adaptive context, but do not support a strong role for SSB in the evolution of less ornamented males in this system.

“…We also note that the variance partitioning approach used to model IGEs in this paper is mathematically equivalent to the alternative (but complementary) ‘trait based’ approach advocated by others 15 , 18 , 36 . In this latter framework, an interaction effect coefficient ψ (‘psi’), captures the effect of a measured conspecific trait (or traits) on focal phenotype.…”

Behavioural ecology research increasingly focuses on why genetic behavioural variation can persist despite selection. Evolutionary theory predicts that directional selection leads to evolutionary change while depleting standing genetic variation. Nevertheless, evolutionary stasis may occur for traits involved in social interactions. This requires tight negative genetic correlations between direct genetic effects (DGEs) of an individual’s genes on its own phenotype and the indirect genetic effects (IGEs) it has on conspecifics, as this could diminish the amount of genetic variation available to selection to act upon. We tested this prediction using a pedigreed laboratory population of Mediterranean field crickets (Gryllus bimaculatus), in which both exploratory tendency and aggression are heritable. We found that genotypes predisposed to be aggressive (due to DGEs) strongly decreased aggressiveness in opponents (due to IGEs). As a consequence, the variance in total breeding values was reduced to almost zero, implying that IGEs indeed greatly contribute to the occurrence of evolutionary stasis. IGEs were further associated with genetic variation in a non-social behaviour: explorative genotypes elicited most aggression in opponents. These key findings imply that IGEs indeed represent an important overlooked mechanism that can impact evolutionary dynamics of traits under selection.

“…2). This would lead to females preferring to be near smaller females who are perhaps harder to distinguish from males, and vice versa for males (suggested by Han et al ., 2016, although they found no effect of partner body size on same-sex behaviour in water striders Gerris lacustris ). While we would expect chemical communication to be important for mate choice cockroaches (Schal et al ., 1984; as well as for other social interactions: Moore, 1997; Moore et al ., 1997b), it is possible individuals use both chemical cues and morphological traits when searching for a partner.…”

Direct and indirect phenotypic effects on sociability indicate potential to evolve

The decision to leave or join a group is important as group size influences many aspects of organisms’ lives and their fitness. This tendency to socialise with others, sociability, should be influenced by genes carried by focal individuals (direct genetic effects) and by genes in partner individuals (indirect genetic effects), indicating the trait’s evolution could be slower or faster than expected. However, estimating these genetic parameters is difficult. Here, in a laboratory population of the cockroach Blaptica dubia, I estimate phenotypic parameters for sociability: repeatability (R) and repeatable influence (RI), that indicate whether direct and indirect genetic effects respectively are likely. I also estimate the interaction coefficient (Ψ), which quantifies how strongly a partner’s trait influences the phenotype of the focal individual and is key in models for the evolution of interacting phenotypes. Focal individuals were somewhat repeatable for sociability across a three-week period (R = 0.095), and partners also had marginally consistent effects on focal sociability (RI = 0.045). The interaction coefficient was non-zero, although in opposite sign for the sexes; males preferred to associate with larger individuals (Ψmale = −0.130) while females preferred to associate with smaller individuals (Ψfemale = 0.032). Individual sociability was consistent between dyadic trials and in social networks of groups. These results provide phenotypic evidence that direct and indirect genetic effects influence sociability, with perhaps most evolutionary potential stemming from heritable effects of the body mass of partners. Sex-specific interaction coefficients may produce sexual conflict and the evolution of sexual dimorphism in social behaviour.
