The role of male-male aggressive signals in reproductive isolation between two hybridizing warblers
… extensively studied for its role in pre-mating reproductive isolation between species. Sometimes song fails to effectively isolate a species and hybrids are produced, giving an opportunity to investigate the mechanisms of how song might act as a reproductive barrier. The ways in which two …

The Evolutionary Causes and Consequences of Mammalian Hybridization
… in mammals. Hybrid sterility is a common reproductive barrier between species that tends to preferentially manifest in the heterogametic sex and frequently genetically maps to the sex chromosomes. Thus, the sex chromosomes appear to play a special role in hybrid incompatibilities, and …

Investigation of multiple interspecific reproductive barriers in Solanum section Lycopersicon
Interspecific reproductive barriers (IRBs) act to prevent hybridization between close relatives and provide insight on how species maintain their integrity in nature. Wild tomato species (Solanum Section. Lycopersicon) are useful for studying IRBs. The monophyletic tomato clade includes 13 closely …

How Are Rare Species Maintained?: Reproductive Barriers Between Layia jonesii, a Rare Serpentine Endemic, and L. platyglossa
<p>Reproductive barriers are vital to generating new species as well as maintaining distinct species. Investigating reproductive barriers between closely related plant taxa helps us to understand how these barriers are maintained, particularly between rare and widespread relatives. <em>Layia …
