Understanding how pollen moves between species is critical to understanding speciation,
diversification, and evolution of flowering plants. For co-flowering species that share …

It is now well recognised that closely related species can hybridize and exchange genetic
material, which may promote or oppose adaptation and speciation. In some cases …

Because reproductive isolation often evolves gradually, differentiating lineages may retain
the potential for genetic exchange for prolonged periods, providing an opportunity to …

Evolution of a non‐recombining sex‐specific region on the Y (or W) chromosome (NRY) is a
key step in sex chromosome evolution, but how recombination suppression evolves is not …

New species arise through the evolution of reproductive barriers between formerly
interbreeding lineages. Yet, comprehensive assessments of potential reproductive barriers …

The disproportionately large involvement of the X‐chromosome in the isolation of closely
related species (the large‐X effect) has been reported for many animals, where X‐linked …

The existence of sexually antagonistic (SA) polymorphism is widely considered the most
likely explanation for the evolution of suppressed recombination of sex chromosome pairs …

Dispersal, when accompanied by reduced gene flow and natural selection, influences
speciation rates among groups of organisms. We used molecular phylogenetics, divergence …

Abstract Background and Aims When species cohesion is maintained despite ongoing
natural hybridization, many questions are raised about the evolutionary processes operating …

In order to investigate the role of differential adaptation for the evolution of reproductive
barriers, we conducted a multi‐site transplant experiment with the dioecious sister species …
