Patterns of reproductive isolation in toads.
PLoS ONE, 2008 Understanding the general features of speciation is an important goal in evolutionary biology, and despite significant progress, several unresolved questions remain.

What is reproductive isolation? [PDF]
J Evol Biol, 2022 Abstract Reproductive isolation (RI) is a core concept in evolutionary biology. It has been the central focus of speciation research since the modern synthesis and is the basis by which biological species are defined. Despite this, the term is used in seemingly different ways, and attempts to quantify RI have used very different ...

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 ...

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 ...

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.

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.
