“…In contrast to our expectation, clerodanoid uptake, which is known to enhance mate attractiveness in A. rosae (Amano et al 1999; preprint Paul and Müller 2021), had no effect on the measured traits in offspring of both sexes. This is surprising, because partner attractiveness has been shown to affect investment into offspring or/and offspring traits across a wide variety of species (Robart and Sinervo 2019), including also multigenerational consequences (Gilbert et al 2012; Wilson et al 2019). In other species, mating with more attractive partners has mostly direct effects for the partner, but not necessarily for the offspring.…”

Intergenerational effects, also known as parental effects in which the offspring phenotype is influenced by the parental phenotype, can occur in response to parental early life food-limitation and adult reproductive environment. However, little is known about how these parental life stage-specific environments interact with each other and with the offspring environment to influence offspring phenotypes, particularly in organisms that realize distinct niches across ontogeny. We examined the effects of parental early life starvation and adult reproductive environment on offspring traits under matching or mismatching offspring early life starvation conditions using the insect Athalia rosae (turnip sawfly). The parental early life starvation treatment had context-dependent intergenerational effects on life-history and consumption traits of offspring larvae, partly in interaction with offspring conditions (intragenerational effects) and sex, while there was no significant effect of parental adult reproductive environment. In addition, parental starvation led to differential expression of only few genes, while offspring larval starvation caused a pronounced differential gene expression and modulation of multiple pathways. Our findings reveal that parental starvation leads to intergenerational effects on offspring life-history traits, consumption patterns as well as gene expression, although the effects are less pronounced than those of offspring starvation.

“…Only females reared in an acoustic environment with variable-quality male calls showed higher offspring quality when mated with high-quality males. Differential female investment in offspring according to male quality is a widespread strategy, both before (e.g., Cunningham and Russell 2000) and after offspring birth (e.g., Robart and Sinervo 2019). Male traits perceived by females may influence female reproductive investment in egg number and size (e.g., Pischedda et al 2011;Poisbleau et al 2013), as well as in maternal care (e.g., Robart and Sinervo 2019).…”

Changes in resource allocation to the offspring and also in the quality of parental behaviors in response to male quality are known mechanisms of cryptic female choice (reviewed in Ratikainen andKokko 2010 andFirman et al 2018).…”

Pre-maturation social experience affects female reproductive strategies and offspring fitness in a highly polyandrous insect

The pre-maturation social environment experienced by females may affect their post-maturation reproductive strategies, including mating preferences and investment in offspring. Whether the pre-maturation social environment also affects other aspects of females’ reproductive strategies, such as the degree of polyandry and post-copulatory decisions, is still an open question. To address this question, we performed laboratory experiments using the cricket Teleogryllus commodus, a highly polyandrous species. Previous studies showed that juvenile females reared in an acoustic environment with recorded male calls with different rates (variable-quality, VQ) are more responsive to high-quality calls than females reared in an environment with recorded male calls with only high rates (high-quality, HQ). We exposed juvenile females to these same two acoustic environments and estimated their degree of polyandry, offspring fitness, and time of spermatophore retention. We found that the juvenile acoustic environment did not change a female’s mating rate, indicating that the higher responsiveness shown in a previous study does not translate into higher degree of polyandry. An increased number of mates reduced offspring fitness, suggesting that there is an optimum number of mates for females. Finally, females from the VQ group retained spermatophores for shorter periods and produced higher quality offspring when mated with high-quality males, suggesting that the pre-maturation acoustic environment interacts with the quality of the males to determine post-copulatory female decisions and eventually offspring fitness. Taken together, our results indicate that both the pre- and post-mating strategies of females are subject to socially induced plasticity.

“…However, the available evidence suggests that such kind of compensatory efforts do not usually overcome the associated in term of survival prospects (Gowaty et al , Harris and Uller ). Recent reviews consider the compensatory and the sexual selection models explaining differential investment as the two ends of a continuum of possible strategies from positive to negative differential allocation depending on the life history of organisms, rather than competing hypotheses (Harris and Uller , Haaland et al , Robart and Sinervo ). The ‘Haaland et al model’ () suggests, that most cost/benefit scenarios of parental investment bend towards positive differential allocation, especially when the investment produces higher benefits on offspring when mated with high quality partners than when mated with low quality ones.…”

Hoopoe Upupa epops male feeding effort is related to female cosmetic egg colouration

Avian eggshell colouration might function as a post‐mating sexually selected signal of female quality, influencing male parental investment and, hence, reproductive success. This hypothesis has been tested for intrinsic eggshell pigments as biliverdin (blue‐green colouration) and/or protoporphyrin (brown coloured spots), but never for colourations applied post‐laying. Post‐laying staining colouration due to, for instance, uropygial secretion of the female could reflect its phenotypic properties and, thus, might be a cue for male investment in reproduction. In hoopoes, the uropygial gland of incubating females hosts symbiotic bacteria that are responsible for the brown colour of their uropygial secretion and of the eggshells, as they cover their bluish‐grey eggshells with gland secretion after laying. The secretion protects embryos from pathogenic trans‐shell infections and, thus, egg colouration may function as a cue or even as a post‐mating sexually selected signal of antimicrobial potential in hoopoes. In a wild hoopoe population breeding in nest boxes in Spain, we test this hypothesis by exploring whether egg colour predicts male parental investment. In accordance with the hypothesis, we found that the amount of food provided by males to incubating females was higher in nests with less saturated eggshell colours. This relationship was affected by female body condition. High quality females in terms of body condition and/or in secretion colour obtained better males in terms of provisioning effort during incubation. Given that eggshell saturation is negatively related to density of bacterial symbionts in uropygial secretions, one possibility is that males may regulate their parental investment in accordance to the expected characteristics of mutualistic bacteria hosted in uropygial glands and deposited on eggshells. We discuss alternative explanations for our results, concluding that the post‐mating sexual selection hypothesis is the most likely but experimental modification of egg colour is needed to test it further.
