Juvenile social experience and practice have a switch‐like influence on adult mate preferences in an insect

Social causes of variation in animal communication systems have important evolutionary consequences, including speciation. The relevance of these effects depends on how widespread they are among animals. There is evidence for such effects not only in birds and mammals, but also frogs and some insects and spiders. Here, we analyze the social ontogeny of adult mate preferences in an insect, Enchenopa treehoppers. In these communal plant‐feeding insects, individuals reared in isolation or in groups differ in their mate preferences, and the group‐reared phenotype can be rescued by playbacks to isolation‐reared individuals. We ask about the relative role of signaling experience and signaling practice during ontogeny on the development of adult mating preferences in Enchenopa females. Taking advantage of variation in the signal experience and signaling practice of isolation‐reared individuals, we find switch‐like effects for experience and practice on female mate preference phenotypes, with individuals having some experience and practice as juveniles best rescuing the group‐reared preference phenotype. We discuss how understanding the nature and distribution of social‐ontogenetic causes of variation in mate preferences and other sexual traits will bring new insights into how within‐ and between‐population variation influences the evolution of communication systems.

“…In the context of socially induced plasticity, the developmental environment is recognized to have profound effects on the reproductive phenotype in adulthood. Such effects can influence mechanisms of sexual selection: a phenomenon that is exemplified by studies demonstrating specific mate choice preferences among females reared in different social contexts [13][14][15]. Moreover, exposure to different levels of perceived male-male competition during development can lead to adaptive responses in males.…”

Intergenerational response to sperm competition risk in an invasive mammal

et al. 2023

Studies of socially mediated phenotypic plasticity have demonstrated adaptive male responses to the ‘competitive’ environment. Despite this, whether variation in the paternal social environment also influences offspring reproductive potential in an intergenerational context has not yet been examined. Here, we studied the descendants of wild-caught house mice, a destructive pest species worldwide, to address this knowledge gap. We analysed traits that define a ‘competitive’ phenotype in the sons of males (sires) that had been exposed to either a high-male density (competitive) or high-female density (non-competitive) environment. We report disparate reproductive strategies among the sires: high-male density led to a phenotype geared for competition, while high-female density led to a phenotype that would facilitate elevated mating frequency. Moreover, we found that the competitive responses of sires persisted in the subsequent generation, with the sons of males reared under competition having elevated sperm quality. As all sons were reared under common-garden conditions, variation in their reproductive phenotypes could only have arisen via nongenetic inheritance. We discuss our results in relation to the adaptive advantage of preparing sons for sperm competition and suggest that intergenerational plasticity is a previously unconsidered aspect in invasive mammal fertility control.
