Cryptic Sexual Selection - More Control Issues 1
Identifying the evolutionary processes that cause genetic and phenotypic divergence among species is one of the fundamental goals of evolutionary biologists. Darwin (1871) first pointed out that male traits such as plumage coloration, which he hypothesized to influence sexual selection, rapidly diverge among closely related species. In an earlier book (Sexual Selection and Animal Genitalia; Ebe...
متن کاملThe evolution of alternative cryptic female choice strategies in age-structured populations.
Cryptic female choice is a potentially important aspect of the sexual selection process. According to the theory of sexual dialectics, postcopulation manipulation of relative male fertilization success can provide an avenue by which females can circumvent attempts by males to control female reproduction. Here I use stochastic models to investigate the evolution of cryptic female choice in popul...
متن کاملThe effect of cryptic female choice on sex allocation in simultaneous hermaphrodites.
Sex allocation theory for simultaneous hermaphrodites has focused primarily on the effects of sperm competition, but the role of mate choice has so far been neglected. We present a model to study the coevolution of cryptic female choice and sex allocation in simultaneous hermaphrodites. We show that the mechanism of cryptic female choice has a strong effect on the evolutionary outcome: if indiv...
متن کاملCriteria for demonstrating postcopulatory female choice.
The recent discussion of Birkhead (1998) may cause confusion regarding the nature of cryptic female choice and how to test for its occurrence. Here I attempt to (1) clarify the distinction between cryptic female choice and ‘‘sperm choice,’’ the primary focus of Birkhead’s discussion; (2) present more appropriate criteria for demonstrating cryptic female choice; (3) describe errors resulting fro...
متن کاملCryptic female choice during spermatophore transfer in Tribolium castaneum (Coleoptera: Tenebrionidae).
Sexual selection in both males and females promotes traits and behaviors that allow control over paternity when female mates with multiple males. Nonetheless, mechanisms of cryptic female choice have been consistently overlooked, due to traditional focus on sperm competition as well as difficulty in distinguishing male vs. female influence over processes occurring during and after mating. The f...
متن کاملNo evidence for external genital morphology affecting cryptic female choice and reproductive isolation in Drosophila.
Genitalia are one of the most rapidly diverging morphological features in animals. The evolution of genital morphology is proposed to be driven by sexual selection via cryptic female choice, whereby a female selectively uptakes and uses a particular male's sperm on the basis of male genital morphology. The resulting shifts in genital morphology within a species can lead to divergence in genital...
