Although sexual interactions between species (reproductive interference) have been
reported from a wide range of animal taxa, their potential for determining species …

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 …

Reproductive isolation is an intrinsic aspect of species formation. For that reason, the
identification of the precise isolating traits, and the rates at which they evolve, is crucial to …

Sexual selection is a major force driving the evolution of diverse reproductive traits. This
evolutionary process is based on individual reproductive advantages that arise either …

Publisher Summary There is general recognition among evolutionists that no matter how
one defines a species, the boundaries between distinct, sexually reproducing species are …

Mechanisms that prevent different species from interbreeding are fundamental to the
maintenance of biodiversity. Barriers to interspecific matings, such as failure to recognize a …

Endosymbiotic reproductive manipulators are widely studied as sources of postzygotic
isolation in arthropods, but their effect on prezygotic isolation between genetically …

Genitalia appear to evolve rapidly and divergently in taxa with internal fertilization. The
current consensus is that intense directional sexual selection drives the rapid evolution of …

By tradition, speciation research has been focused on processes leading to either premating
or post‐zygotic reproductive isolation. The processes which generate isolation after mating …

Conspecific gamete precedence, the usage of conspecific sperm by a female that mates with
both a conspecific and a heterospecific male, has been found in many taxa. We construct a …
