Mate preference for a phenotypically plastic trait is learned, and may facilitate preference-phenotype matching.
Fixed, genetically determined, mate preferences for species whose adult phenotype varies with rearing environment may be maladaptive, as the phenotype that is most fit in the parental environment may be absent in the offspring environment. Mate preference in species with polyphenisms (environmentally dependent alternative phenotypes) should therefore either not focus on polyphenic traits, be po...
متن کاملBateman's principle and immunity: phenotypically plastic reproductive strategies predict changes in immunological sex differences.
The sexes often differ in the reproductive trait limiting their fitness, an observation known as Bateman's principle. In many species, females are limited by their ability to produce eggs while males are limited by their ability to compete for and successfully fertilize those eggs. As well as promoting the evolution of sex-specific reproductive strategies, this difference may promote sex differ...
متن کاملPhenotypically plastic adjustment of sex allocation in a simultaneous hermaphrodite.
Sex allocation theory for simultaneous hermaphrodites predicts an influence of the mating group size on sex allocation. Mating group size may depend on the size of the group in which an individual lives, or on the density, but studies to date have not distinguished between the two factors. We performed an experiment in which we raised a transparent simultaneous hermaphrodite, the flatworm Macro...
متن کاملParallel evolution of sexual isolation in sticklebacks.
Mechanisms of speciation are not well understood, despite decades of study. Recent work has focused on how natural and sexual selection cause sexual isolation. Here, we investigate the roles of divergent natural and sexual selection in the evolution of sexual isolation between sympatric species of threespine sticklebacks. We test the importance of morphological and behavioral traits in conferri...
متن کاملParasites may contribute to ‘magic trait’ evolution in the adaptive radiation of three-spined sticklebacks, Gasterosteus aculeatus (Gasterosteiformes: Gasterosteidae)
In the past decade, there has been a new effort to understand the ecology that drives population divergence and speciation. It is well established in theory that speciation is most likely to occur when a trait that is under divergent natural selection in different populations is also used in mate choice. Such traits have been dubbed ‘magic traits’ (Gavrilets, 2004) and, although there appears t...
