Admixture of evolutionary rates across a butterfly hybrid zone

eLife, 2022
Hybridization is a major evolutionary force that can erode genetic differentiation between species, whereas reproductive isolation maintains such differentiation.

THE EVOLUTION OF STRONG REPRODUCTIVE ISOLATION [PDF]

Evolution, 2009
Felsenstein distinguished two ways by which selection can directly strengthen isolation. First, a modifier that strengthens prezygotic isolation can be favored everywhere. This fits with the traditional view of reinforcement as an adaptation to reduce deleterious hybridization by strengthening assortative mating. Second, selection can favor association

Divergent evolution of male aggressive behaviour : another reproductive isolation barrier in extremophile poeciliid fishes? [PDF]

, 2011
Reproductive isolation among locally adapted populations may arise when immigrants from foreign habitats are selected against via natural or (inter-)sexual selection (female mate choice).

Divergent adaptation promotes reproductive isolation among experimental populations of the filamentous fungus Neurospora

BMC Evolutionary Biology, 2008
Background An open, focal issue in evolutionary biology is how reproductive isolation and speciation are initiated; elucidation of mechanisms with empirical evidence has lagged behind theory.

Extensive historical and contemporary hybridization suggests premating isolation in Vermivora warblers is not strong: A reply to Confer et al.

Ecology and Evolution, 2021
We present comments on an article published by Confer et al. (Ecology and Evolution, 10, 2020). Confer et al. (2020) aggregate data from multiple studies of social pairing between Vermivora chrysoptera and V.

Reproductive Isolation during Domestication [PDF]

The Plant Cell, 2012
It has been hypothesized that reproductive isolation should facilitate evolution under domestication. However, a systematic comparison of reproductive barrier strength between crops and their progenitors has not been conducted to test this hypothesis. Here, we present a systematic survey of reproductive barriers between 32 economically important crop ...

QTL mapping reveals the genetic architecture of loci affecting pre- and post-zygotic isolating barriers in Louisiana Iris

BMC Plant Biology, 2012
Background Hybridization among Louisiana Irises has been well established and the genetic architecture of reproductive isolation is known to affect the potential for and the directionality of introgression between taxa. Here we use co-dominant markers to

Evolution and molecular bases of reproductive isolation. [PDF]

Curr Opin Genet Dev, 2022
The most challenging problem in speciation research is disentangling the relative strength and order in which different reproductive barriers evolve. Here, we review recent developments in the study of reproductive isolation in yeasts. With over a thousand genome-sequenced isolates readily available for testing the viability, sterility, and fitness of ...
