Cryptic female choice (CFC) represents postmating intersexual selection arising from female-
driven mechanisms at or after mating that bias sperm use and impact male paternity share …

How barriers to gene flow arise and are maintained are key questions in evolutionary
biology. Speciation research has mainly focused on barriers that occur either before mating …

Interactions between sperm and the female reproductive tract (FRT) are critical to
reproductive success and yet are poorly understood. Because sperm complete their …

Proteins on gamete surfaces are major determinants of fertilization success, particularly in
free-spawning animals. Molecular analyses of these simple genetic systems show rapid …

Background Identifying traits that reproductively isolate species, and the selective forces
underlying their divergence, is a central goal of evolutionary biology and speciation …

In contrast to sexual selection on traits that affect interactions between the sexes before
mating, little theoretical research has focused on the coevolution of postmating traits via …

Mammalian sperm must spend a minimum period of time within a female reproductive tract
to achieve the capacity to fertilize oocytes. This phenomenon, termed sperm 'capacitation' …

Despite evidence that variation in male–female reproductive compatibility exists in many
fertilization systems, identifying mechanisms of cryptic female choice at the gamete level has …

Postcopulatory sexual selection is credited with driving rapid evolutionary diversification of
reproductive traits and the formation of reproductive isolating barriers between species. This …

In numerous species, egg chemoattractants play a critical role in guiding sperm towards
unfertilized eggs (sperm chemotaxis). Until now, the known functions of sperm chemotaxis …
