No evidence for reproductive isolation through sexual conflict in the bulb mite Rhizoglyphus robini. [PDF]

PLoS ONE, 2013
Sexual conflict leading to sexual antagonistic coevolution has been hypothesized to drive reproductive isolation in allopatric populations and hence lead to speciation. However, the generality of this speciation mechanism is under debate.

Starvation-associated genome restructuring can lead to reproductive isolation in yeast. [PDF]

PLoS ONE, 2013
Knowledge of the mechanisms that lead to reproductive isolation is essential for understanding population structure and speciation. While several models have been advanced to explain post-mating reproductive isolation, experimental data supporting most ...

Genomic islands of speciation in Anopheles gambiae. [PDF]

PLoS Biology, 2005
The African malaria mosquito, Anopheles gambiae sensu stricto (A. gambiae), provides a unique opportunity to study the evolution of reproductive isolation because it is divided into two sympatric, partially isolated subtaxa known as M form and S form ...

Clustering of loci controlling species differences in male chemical bouquets of sympatric Heliconius butterflies

Ecology and Evolution, 2021
The degree to which loci promoting reproductive isolation cluster in the genome—that is, the genetic architecture of reproductive isolation—can influence the tempo and mode of speciation.

A single pleiotropic locus influences the rate of hybridization between two sibling species of Lygaeus bugs

Ecology and Evolution, 2020
The evolution of reproductive isolation lies at the heart of understanding the process of speciation. Of particular interest is the relationship between pre‐ and postzygotic reproductive isolation, and the genetic architecture of traits that contribute ...

Reproductive isolation of hybrid populations driven by genetic incompatibilities. [PDF]

PLoS Genetics, 2015
Despite its role in homogenizing populations, hybridization has also been proposed as a means to generate new species. The conceptual basis for this idea is that hybridization can result in novel phenotypes through recombination between the parental ...

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.

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.

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.

Clinal genomic analysis reveals strong reproductive isolation across a steep habitat transition in stickleback fish

Nature Communications, 2021
How ecological divergence causes reproductive isolation between populations in close contact remains poorly understood at the genomic level. This study presents a clinal investigation based on whole-genome sequencing to characterize reproductive ...
