“…These results represent a generalization of those in Gavrilets et al (2001;see also Gavrilets & Waxman 2002;Rowe et al 2003 and a review of similar models in Gavrilets & Hayashi 2005) for the case of more general functions j and w f . Other generalizations have also been explored.…”

We consider mathematical models describing the evolutionary consequences of antagonistic interactions between male offence, male defence and female reproductive tract and physiology in controlling female mating rate. Overall, the models support previous verbal arguments about the possibility of continuous coevolutionary chase between the sexes driven by two-way (e.g. between male offence and female traits) and three-way (e.g. between male offence, male defence and female traits) inter-sexual antagonistic interactions. At the same time, the models clarify these arguments by identifying various additional potential evolutionary dynamics and important parameters (e.g. genetic variances, female optimum mating rates, strength of selection in females and the relative contributions of first and second males into offspring) and emphasizing the importance of initial conditions. Models also show that sexual conflict can result in the evolution of monandry in an initially polyandrous species and in the evolution of random mating in a population initially exhibiting non-random mating.

“…The results of population crosses are not necessarily diagnostic of the existence of sexual conflict (Rowe et al 2003), so we do not claim that sexual conflict does or does not occur in these populations. Rather, our results indicate that if sexual conflict occurs, it must interact with ecological divergence to drive the evolution of reproductive isolation.…”

“…The results for parapatric pairs are in the same direction, but less definitive and relatively heterogeneous. The observed heterogeneity among population pairs might be expected for sexual forms of reproductive isolation if different traits and different mutations are involved in different populations (Schluter & Price 1993;Parker & Partridge 1998;Rowe et al 2003). Some specific pairs of parapatric populations exhibited significantly reduced female fecundity in between-population crosses, but most did not (table 2).…”

Speciation can involve the evolution of 'cryptic' reproductive isolation that occurs after copulation but before hybrid offspring are produced. Because such cryptic barriers to gene exchange involve post-mating sexual interactions, analyses of their evolution have focused on sexual conflict or traditional sexual selection. Here, we show that ecological divergence between populations of herbivorous walking sticks is integral to the evolution of cryptic reproductive isolation. Low female fitness following between-population mating can reduce gene exchange between populations, thus acting as a form of cryptic isolation. Female walking sticks show reduced oviposition rate and lower lifetime fecundity following between-population versus within-population mating, but only for mating between populations using different host-plant species. Our results indicate that even inherently sexual forms of reproductive isolation can evolve as a byproduct of ecological divergence and that post-mating sexual interactions do not necessarily evolve independently of the ecological environment.

“…This suggests that there is very limited variability in this trait within a single population. Thus, population crosses or gonopodium experimental manipulation would be required to assess the role that genital hooks play in mediating the success of forced matings (but see [59]). Our analysis also revealed corresponding patterns of trait diversification in female genital morphology (relative oviduct width).…”

Intraspecific evidence from guppies for correlated patterns of male and female genital trait diversification

et al. 2011

The role of sexual selection in fuelling genital evolution is becoming increasingly apparent from comparative studies revealing interspecific divergence in male genitalia and evolutionary associations between male and female genital traits. Despite this, we know little about intraspecific variance in male genital morphology, or how male and female reproductive traits covary among divergent populations. Here we address both topics using natural populations of the guppy, Poecilia reticulata, a livebearing fish that exhibits divergent patterns of male sexual behaviour among populations. Initially, we performed a series of mating trials on a single population to examine the relationship between the morphology of the male's copulatory organ (the gonopodium) and the success of forced matings. Using a combination of linear measurements and geometric morphometrics, we found that variation in the length and shape of the gonopodium predicted the success of forced matings in terms of the rate of genital contacts and insemination success, respectively. We then looked for geographical divergence in these traits, since the relative frequency of forced matings tends to be greater in high-predation populations. We found consistent patterns of variation in male genital size and shape in relation to the level of predation, and corresponding patterns of (co)variation in female genital morphology. Together, these data enable us to draw tentative conclusions about the underlying selective pressures causing correlated patterns of divergence in male and female genital traits, which point to a role for sexually antagonistic selection.
