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 …

Sperm experience intense and varied selection that dramatically impacts the evolution of
sperm quality. Selection acts to ensure that sperm are fertilization-competent and able to …

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

Sexual reproduction and the exchange of genetic information are essential biological
processes for species across all branches of the tree of life. Over the last four decades …

Climate change driven ocean acidification and hypercapnia may have a negative impact on
fertilization in marine organisms because of the narcotic effect these stressors exert on …

Animal fertilization is governed by the interaction (binding) of proteins on the surfaces of
sperm and egg. In many examples presented herein, fertilization proteins evolve rapidly and …

Many marine invertebrate taxa are broadcast spawners, where multiple individuals release
their gametes into the water for external fertilization, often in the presence of gametes from …

At the end of the last century, sexual conflict was identified as a powerful engine of
speciation, potentially even more important than ecological selection. Earlier work that …

Proteins involved in reproduction often evolve rapidly, raising the possibility that changes in
these proteins contribute to reproductive isolation between species. We review the evidence …
