Evolutionary ecology of sexual reproduction: sexual selection, reproductive interference, and community structure<\/span><\/span><\/span><\/p>\n

In sexually reproducing organisms, mating with individuals of the opposite sex is necessary to produce offspring. Mating process raises competition for mating opportunities among same-sex individuals (i.e. sexual selection) and the conflict of evolutionary interest between the sexes (sexual conflict), which drive the evolution of reproductive traits. Because reproductive traits can mediate interspecific interactions (e.g. reproductive interference), reproductive trait evolution can eventually influence the community structure. In this talk, I present three different studies that are related to the evolutionary ecology of sexual reproduction, and by doing so I discuss ways in which sexual reproduction is relevant to the origin and\/or maintenance of biodiversity. First, I show a likely case of sexual conflict in a sexually reproducing dandelion, where the timing of flower closure is influenced by the identity of the pollen deposited on the stigma. Second, I present a case study of how reproductive trait evolution due to within-species sexual selection can mediate the strength of reproductive interference in a pair of seed beetle species. Third, I present a simulation model of secondary contact with genetically incompatible hybridization. This model suggests that habitat segregation can evolve without tradeoff in resource use ability and that habitat segregation is more likely to be found in nature than species recognition divergence, which has historically been more appreciated than habitat segregation in this context. I will also briefly present some of my ongoing projects and discuss future research plans.<\/span><\/span><\/span><\/p>\n
