“…Behavioral advantages conferred to infected males by Wolbachia, such as increased competitiveness and mating rate, have been previously shown in Drosophila (Champion de Crespigny et al 2006;Panteleev et al 2007). In line with this, the shorter mating latency observed for infected males relative to uninfected males in the population CH, together with the tendency for these males to mate with more females than uninfected males in the mate choice test (about 64 %), may indicate that Wolbachia increased male competitiveness in this population, as found in other systems (Hosken et al 2008;Katsuki et al 2016). However, this tendency was not observed in the other populations studied here, and a previous study in T. urticae did not find an effect of Wolbachia on male competitiveness (Zhao et al 2013).…”

Arthropods are often infected with Wolbachia inducing cytoplasmic incompatibility (CI), whereby crosses between uninfected females and infected males yield unviable fertilized offspring. Although uninfected females benefit from avoiding mating withWolbachia-infected males, this behavior is not always present in host populations and its evolution may hinge upon various factors.Here, we used spider mites to test whether CI could select for mate preference in uninfected females in absence of kin recognition.We found that uninfected females from several field-derived populations showed no preference for infected or uninfected males, nor evolved a preference after being exposed to CI for 12-15 generations by maintaining uninfected females with both infected and uninfected males (i.e., stable "infection polymorphism"). This suggests that Wolbachia-mediated mate choice evolution may require very specific conditions in spider mites. However, after experimental evolution, the copulation duration of Wolbachiainfected control males was significantly higher than that of uninfected control males, but not than that of uninfected males from the "infection polymorphism" regime. This result illustrates how gene flow may oppose Wolbachia-driven divergence between infected and uninfected hosts in natural populations.

“…A positive relationship between a male's mating success and his paternity share, which would be expected to reinforce sexual selection on male mating success (14), has been found in several species, including junglefowl, Gallus gallus, guppies, Poecila reticulata, and fruit flies, Drosophila melanogaster (10,(29)(30)(31)(32). In other taxa, however, this relationship may be negative (33)(34)(35), indicating that precopulatory and postcopulatory episodes represent alternative pathways to male reproductive success, thereby creating opportunities for alternative male mating tactics. Finally, in other species, episodes of precopulatory and postcopulatory sexual selection are largely independent (17,36,37).…”

Structure of sexual networks determines the operation of sexual selection

Sexual selection is a fundamental evolutionary process but remains debated, particularly in the complexity of polyandrous populations where females mate with multiple males. This lack of resolution is partly because studies have largely ignored the structure of the sexual network, that is, the pattern of mate sharing. Here, we quantify what we call mating assortment with network analysis to specify explicitly the indirect as well as direct relationships between partners. We first review empirical studies, showing that mating assortment varies considerably in nature, due largely to basic properties of the sexual network (size and density) and partly to nonrandom patterns of mate sharing. We then use simulations to show how variation in mating assortment interacts with population-level polyandry to determine the strength of sexual selection on males. Controlling for average polyandry, positive mating assortment, arising when more polygynous males tend to mate with more polyandrous females, drastically decreases the intensity of precopulatory sexual selection on male mating success (Bateman gradient) and the covariance between male mating success and postcopulatory paternity share. Average polyandry independently weakened some measures of sexual selection and crucially also impacted sexual selection indirectly by constraining mating assortment through the saturation of the mating network. Mating assortment therefore represents a key-albeit overlooked-modulator of the strength of sexual selection. Our results show that jointly considering sexual network structure and average polyandry more precisely describes the strength of sexual selection.
