“…Although many workers continue to test predictions of the good-genes and related hypotheses (e.g., Sardell et al 2014;Montoya and Torres 2015;Howie et al 2019), the claim that indirect selection on preference is expected to be relatively weak in some general or theoretical sense continues to be made (e.g., Kuijper et al 2012;Ryan and Cummings 2013;Rosenthal 2017;Fitzpatrick and Servedio 2018;Svensson 2019;Kelly and Adam-Granger 2020). The relative importance of direct and indirect selection on preference is an empirical question that can only be answered by careful comparisons of somatic and genetic benefits of mate choices in species representing a wide range of mating systems.…”

“…This conclusion was reached in an influential theoretical paper by Kirkpatrick and Barton (1997), and was later arrived at by a somewhat different line of reasoning by Cameron et al (2003). It has since become widely accepted (e.g., Kokko et al 2006;Hettyey et al 2010;Kuijper et al 2012;Ryan and Cummings 2013;Kiyose et al 2015;Rosenthal 2017;Fitzpatrick and Servedio 2018;Suzaki et al 2018;Svensson 2019;Kelly and Adam-Granger 2020;Madjidian et al 2020). For example, in a review of sexual selection theory, Kuijper et al (2012) cite both Kirkpatrick and Barton (1997) and Cameron et al (2003) in support of the statement that "even slight costs can override indirect benefits of choosiness, leading to the theoretical expectation that sexual selection driven only by indirect benefits of choosiness is rare in nature."…”

A reexamination of theoretical arguments that indirect selection on mate preference is likely to be weaker than direct selection

Female preference for male ornaments or displays can evolve by indirect selection resulting from genetic benefits of mate choices, or by direct selection resulting from nongenetic benefits or selection on sensory systems occurring in other contexts. In an influential paper, Kirkpatrick and Barton used a good‐genes model and evolutionary rates estimated from the fossil record to conclude that indirect selection on preference is likely to be weak compared to typical strengths of direct selection. More recent authors have extrapolated from Kirkpatrick and Barton's conclusions to suggest that the presence of preference‐trait genetic correlations in equations for indirect but not direct selection gives a purely theoretical basis to the conclusion that the former is likely to be weaker than the latter. Here, I challenge these views, and argue that the relative importance of direct and indirect selection on preference is an empirical issue that defies simple generalizations. First, I show that Kirkpatrick and Barton based their conclusion on a questionable claim about typical rates of evolution due to direct selection. Second, I argue that claiming that direct selection on preference is stronger than indirect selection because only equations for the latter contain a genetic correlation mistakes the mathematical simplicity with which direct selection is usually represented for evidence regarding its magnitude. By comparing a simple equation for the selection response of preference caused by somatic (“direct”) benefits to Kirkpatrick and Barton's result for the response to indirect selection, I show that indirect selection on preference is not inherently weaker than direct selection. I also point out an important but overlooked reason why selection on preference under the sensory bias hypothesis can be expected to be less effective in the long run than that from either somatic or genetic benefits of mate choices.

“…In other species, mating with more attractive partners can lead to direct effects for the partner, but not necessarily for the offspring. For example, in the field cricket, Gryllus firmus, mating with more attractive males led to a higher number of eggs laid by females but offspring did not show any fitness benefits (Kelly and Adam-Granger 2020). In A. rosae, parental clerodanoid exposure may affect other offspring traits, such as immunity (Bozov et al 2015), lifespan (Zanchi et al 2021), or traits exhibited in adulthood, e.g.…”

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.

“…Female guppies often choose mates based upon the varied expression of male secondary sexual traits, with males possessing novel or rare colour patterns acquiring more mates and siring proportionally more offspring (Hughes et al, 2013). Further, females mated to preferred males have a greater number of pregnancies, faster conception (Parrott et al, 2019), and produce larger broods (Kelly & Adam-Granger, 2020). Given the high level of intrapopulation variation in female-male trait preference (Brooks & Endler, 2001;Hughes et al, 2013), no single male phenotype will be attractive to all females (Brooks & Endler, 2001).…”

The effect of phenotypic heterogeneity on behaviours linked to invasive success

Every year thousands of species are transported and introduced to novel ecosystems around the globe by human activities (Havel et al., 2015;Hulme, 2009;Pimentel et al., 2004). Despite being considered an issue for biodiversity and conservation, the majority of introduced, non-native species fail to establish, or establish without becoming invasive (Holway & Suarez, 1999;Milbau & Stout, 2008).Nonetheless, even a small proportion of successful invasive species can become problematic and lead to severe ecological and economic impacts (Carter et al., 2021;Clavero & Garcia-Berthou, 2005;Park, 2004). Given the difficulty of eradicating invasive species, it is critical that we can accurately identify which species and/or populations pose the greatest risk of becoming problematic invasive species (Holway & Suarez, 1999). While the economic and ecological costs of invasive species are unequivocal, current ability to forecast species' invasive propensity remains limited. Namely, our understanding of how population-level traits contribute to a species' invasive success has not been fully explored. In this study, we address this knowledge gap by investigating the contribution of phenotypic
