Indirect genetic effects (IGEs) occur when genes expressed in one individual affect the phenotype of a conspecific. Theoretical models indicate that the evolutionary consequences of IGEs critically depend on the genetic architecture of interacting traits, and on the strength and direction of phenotypic effects arising from social interactions, which can be quantified by the interaction coefficient C. In the context of sexually selected traits, strong positive C tends to exaggerate evolutionary change, whereas negative C impedes sexual trait elaboration. Despite its theoretical importance, whether and how C varies among geographically distinct populations is unknown. Such information is necessary to evaluate the potential for IGEs to contribute to divergence among isolated or semi-isolated populations. Here, we report substantial variation in C for a behavioural trait involved in sexual selection in the field cricket Teleogryllus oceanicus: female choosiness. Both the strength and direction of C varied among geographically isolated populations. C also changed over time. In a contemporary population of crickets from Kauai, experience of male song increased female choosiness. In contrast, experience of male song decreased choosiness in an ancestral population from the same location. This rapid change corroborates studies examining the evolvability of C and demonstrates how interpopulation variation in the interaction coefficient might influence sexual selection and accelerate divergence of traits influenced by IGEs that contribute to reproductive isolation in nascent species or subspecies.

“…Examples where social environments and IGEs are predicted to affect trait expression and evolution involve interacting phenotypes such as communication, signaling, aggression, dominance, learning, sexual conflict, and sexual selection Bleakley et al 2010;Wolf and Moore 2010). But despite the intended connection to behavioral ecology, research on IGEs has until recently been concentrated in the fields of quantitative and behavioral genetics.…”

“…Focal and interacting behaviors are frequently known in advance in behavioral ecology studies, which may account for the increasing popularity of estimating ψ. Other resources provide detailed mathematical treatment of ψ and guidance on how to estimate it (e.g., Bleakley et al 2010;Schneider et al 2017), so we confine our remarks to a brief conceptual overview highlighting the importance of the parameter (and its multivariate counterpart, Ψ Ψ) plus several recent studies that have estimated it.…”

Indirect genetic effects in behavioral ecology: does behavior play a special role in evolution?

Behavior is rapidly flexible and highly context-dependent, which poses obvious challenges to researchers attempting to dissect its causes. However, over a century of unresolved debate has also focused on whether the very flexibility and context-dependence of behavior lends it a unique role in the evolutionary origins and patterns of diversity in the Animal Kingdom. Here, we propose that both challenges can benefit from studying how indirect genetic effects (IGEs: the effects of genes expressed in one individual on traits in another individual) shape behavioral phenotypes. We provide a sketch of the theoretical framework that grounds IGEs in behavioral ecology research and focus on recent advances made from studies of IGEs in areas of behavioral ecology such as sexual selection, sexual conflict, social dominance, and parent-offspring interactions. There is mounting evidence that IGEs have important influences on behavioral phenotypes associated with these processes, such as sexual signals and preferences and behaviors which function to manipulate interacting partners. IGEs can also influence both responses to selection and selection itself, and considering IGEs refines evolutionary predictions and provides new perspectives on the origins of seemingly perplexing behavioral traits. A key unresolved question, but one that has dominated the behavioral sciences for over a century, is whether behavior is more likely than other types of traits to contribute to evolutionary change and diversification. We advocate taking advantage of an IGE approach to outline falsifiable hypotheses and a general methodology to rigorously test this frequently proposed, yet still contentious, special role of behavior in evolution.

“…Each individual in the colony has a genetic architecture that is derived from a solitary ancestor, but is now affected by the genotypes and the evolution of the social partners in the colony as well. Theory of indirect genetic effects is advanced Wade 2005, 2009;McGlothlin et al 2010;Wolf et al 1998), and considerable progress has been made in understanding social effects on individual phenotypes in simple social groups (Bleakley et al 2011). However, in settings as complex as insect societies, we understand very little apart from some pioneering work (Linksvayer 2006(Linksvayer , 2007(Linksvayer , 2008Van Zweden et al 2010) on how crucial colony level phenotypes arise from the interactions of individual genotypes in an shared, evolving social setting.…”
