“…This finding replicates those of our previous study in which we found behavioral repeatabilities to be relatively stable across acoustic and silent environments (Rudin et al. ). Conversely, our finding contradicts some other studies which found that, for example, in sticklebacks ( Gasterosteus aculeatus ) the repeatability of boldness was affected by social conditions (Jolles et al.…”

“…We have previously shown that variation in the social environment (using acoustic sexual signals) has a greater effect on the expression of behavior, than variation in a nonsocial environmental stimulus (mechanical shaking) (Rudin et al. ). Although we did not directly test for the presence of IGEs in this study, we show that besides behavioral expression, the social environment also has the potential to considerably affect the evolvability of behaviors.…”

“…Additionally, changes in the social environment, namely male acoustic sexual signals, appear to have a greater impact on the expression and repeatability of these behaviors than an abiotic startle stimulus (Rudin et al. ). Acoustic sexual signals affect traits such as female mate choice, alternative mating tactics, dominance, and aggression in crickets (Bailey et al.…”

“…), we expected crickets exposed to male acoustic sexual signals to be bolder and more explorative and active in an open area, but that the repeatabilities across these environments should be similar (Rudin et al. ). Furthermore, by estimating phenotypic and genetic covariances and correlations, we were able to draw inferences about the degree to which behaviors are free to evolve independently and whether the phenotypic gambit or Cheverud's conjecture apply.…”

The social environment is expected to have substantial effects on behavior, and as a consequence, its heritability and evolvability. We investigated these effects by exposing Australian field crickets (Teleogryllus oceanicus) to either silence or recordings of male acoustic sexual signals. We used a combined pedigree and full‐sib/half‐sib breeding design to estimate the repeatability, heritability, and evolvability of behaviors related to boldness, exploration, and activity. All behaviors measured were significantly repeatable in both social environments. Additionally, most behaviors showed significant heritabilities in the two environments. We found no difference in repeatabilities between the silent and the acoustic environment but did find significant differences in the heritabilities and evolvabilities between these environments. There was a high degree of similarity between the phenotypic covariance matrices across the two environments, while the genotypic covariance matrices were highly dissimilar. Reflecting this, we found significant genotype‐by‐environment interactions for most of the behaviors. Lastly, we found that the repeatable aspect of behavior (“personality”) was significantly heritable for most behaviors, but that these heritabilities were higher in the acoustic than in the silent environment. We conclude that the social environment can have a significant impact on the heritability and evolvability of behavior, and argue that evolutionary inferences from phenotypic studies should be made with caution.

Social modulation of individual differences in dance communication in honey bees

Division of labour is a hallmark of eusocial insect colonies, with different groups of workers engaged in different tasks at the same time. Foraging is a task done by older workers in honey bee colonies. Foragers use the waggle dance behaviour to inform and recruit nest mates to food sources in the environment. The recruitment process incorporates information about the food reward, the colony food stores and the environmental food availability and plays a major role in ensuring efficient exploitation of the food sources available to the colony. However, the role that individual foragers play in driving recruitment is largely unexplored. We observed the dance activity of individual foragers from the same foraging group and showed that there are consistent inter-individual differences within a foraging group leading to a division of labour in the recruitment activity. Next, we studied the effect of changing social interactions on these individual differences. Removing foragers from the group led to an increase in the dance activity of the group of remaining foragers. This was mainly driven by an increase in the dance activity of certain individuals within the foraging groups. In contrast, allowing recruits to join the foraging group had a strong negative effect on the dance activity of all the individual foragers. Our study shows that there is a fine scale division of labour in the recruitment activity within foraging groups and that this is further regulated by changing social interactions. Thus, a complex interplay between individual differences and social interactions drive recruitment activity in honey bees.
