“…Alternatively, some studies demonstrate that the same individuals can have both large weapons or bright colours and competitive ejaculates (i.e. additive relationship; Evans et al, 2003;Pilastro et al, 2004;Malo et al, 2005;Locatello et al, 2006;Hosken et al, 2008), and others have found no such relationship (Pischedda & Rice, 2012;Lewis et al, 2013;Travers et al, 2016). Parker et al (2013) suggested, based on theoretical analyses, that the degree to which males are able to monopolize access to females via precopulatory sexual selection (sensu Emlen & Oring, 1977) may determine the strength and direction of this trade-off among species.…”

Theory predicts trade-offs between pre- and post-copulatory sexually selected traits. This relationship may be mediated by the degree to which males are able to monopolize access to females, as this will place an upper limit on the strength of post-copulatory selection. Furthermore, traits that aid in mate monopolization may be costly to maintain and may limit investment in post-copulatory traits, such as sperm performance. Australian painted dragons are polymorphic for the presence or absence of a yellow gular patch ('bibs'), which may aid them to monopolize access to females. Previous work has shown that there are physiological costs of carrying this bib (greater loss of body condition in the wild). Here, we show that male painted dragons use this bright yellow bib as both an inter- and intrasexual signal, and we assess whether this signal is traded off against sperm performance within the same individuals. We found no relationship between aspects of bib colour and sperm swimming velocity or percentage of motile sperm and suggest that the bib polymorphism may be maintained by complex interactions between physiological or life-history traits including other sperm or ejaculate traits and environmental influences.

“…Post-copulatory processes can produce substantial variation in paternity among males and have the potential to reinforce or counteract the effects of precopulatory selection (Collet et al, 2012;Kvarnemo & Simmons, 2013). Hence, all episodes of sexual selection need to be examined to accurately assess male fitness (Lewis et al, 2013). The relationship between pre-and post-copulatory sexual selection has become a major issue because it informs on whether traits are exposed to similar selection pressures during different episodes of selection, and ultimately this relationship determines the net action of sexual selection (Arnold & Wade, 1984;Webster et al, 1995;Collet et al, 2012;Pischedda & Rice, 2012;Kvarnemo & Simmons, 2013;P elissi e et al, 2014;Devigili et al, 2015).…”

Genetic variation but weak genetic covariation between pre‐ and post‐copulatory episodes of sexual selection in Drosophila melanogaster

When females mate polyandrously, male reproductive success depends both on the male's ability to attain matings and on his ability to outcompete rival males in the fertilization of ova post-copulation. Increased investment in ejaculate components may trade off with investment in precopulatory traits due to resource allocation. Alternatively, pre- and post-copulatory traits could be positively related if individuals can afford to invest heavily in traits advantageous at both episodes of selection. There is empirical evidence for both positive and negative associations between pre- and post-copulatory episodes, but little is known about the genetic basis of these correlations. In this study, we measured morphological, chemical and behavioural precopulatory male traits and investigated their relationship with measures of male fitness (male mating success, remating inhibition and offensive sperm competitiveness) across 40 isofemale lines of Drosophila melanogaster. We found significant variation among isofemale lines, indicating a genetic basis for most of the traits investigated. However, we found weak evidence for genetic correlations between precopulatory traits and our indices of male fitness. Moreover, pre- and post-copulatory episodes of selection were uncorrelated, suggesting selection may act independently at the different episodes to maximize male reproductive success.

“…Courtship involves shortrange male pheromone (Grant 1974) and ultrasound production (Trematerra and Pavan 1995), but the actual behavioural interactions between males and females are very brief. However, successful coupling does require female cooperation, and females are able to reject matings (Grant 1974;Lewis et al 2013). Alternatively, the observed pattern could also be due to smaller females being less able to resist forced matings, as seen in other species (Arnqvist and Rowe 2005).…”

Operational sex ratio does not influence the evolution of male mate choice in the Indian meal moth

The strength of mate choice, pre-copulatory sexual selection more generally, is predicted to vary according to a range of social and demographic factors, including the operational sex ratio (OSR). The OSR influences the number of mating opportunities available to each sex, and can, therefore, strongly influence the degree of intrasexual competition and the cost of mate choice. Accordingly, many animals show short-term plasticity in the strength of mate choice in relation to changes in the OSR. However, whether such change persists over evolutionary time has rarely been tested experimentally. In this study, we examined how female mating success in relation to larval food level and body size differs according to the evolutionary history of their mates, in the Indian meal moth Plodia interpunctella. We used males from populations that have been reared at different adult sex ratios (and, therefore, OSRs) for 130 + generations. We found that small females were more likely to mate compared to large females; however, this effect could not be attributed exclusively to male mate choice. Larval food level also did not influence female mating success. Further, males from different sex ratio regimes did not differ in their likelihood of mating with small females, or those from high-food populations. We suggest that male post-copulatory choice is potentially more important than pre-copulatory choice in this species.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
