The mechanisms of reproductive isolation are a collection of evolutionary mechanisms, behaviors and physiological processes critical for speciation. They...

exchange of genetic information between the two populations leading to reproductive isolation. If the two populations come into contact they will be unable to...

typological or morphological species concept. Ernst Mayr emphasised reproductive isolation, but this, like other species concepts, can be hard or even impossible...

Ecological speciation is a form of speciation arising from reproductive isolation that occurs due to an ecological factor that reduces or eliminates gene...

allochronic isolation, or temporal isolation) is a form of speciation (specifically ecological speciation) arising from reproductive isolation that occurs...

results of each experiment are provided by the reproductive isolation column. Pre-zygotic reproductive isolation means that the reproducing individuals in...

genetic incompatibilities to evolve. These incompatibilities cause reproductive isolation, giving rise to—sometimes rapid—speciation events.: 105  Furthermore...

changes in call frequency among sympatric morphs is correlated with reproductive isolation. A further well-studied circumstance of sympatric speciation is...

competitors existed at the time. A key innovation may result in reproductive isolation, whereby those individuals with the innovation no longer breed with...

In parapatric speciation, two subpopulations of a species evolve reproductive isolation from one another while continuing to exchange genes. This mode of...

natural selection increases the reproductive isolation (further divided to pre-zygotic isolation and post-zygotic isolation) between two populations of species...
