Sexual conflict and reproductive isolation in flies [PDF]

open access: yesBiology Letters, 2009
Sexual conflict is predicted to generate more rapid reproductive isolation between larger populations. While there is some empirical support for this, the data are inconsistent and, additionally, there has been criticism of some of the evidence.

The evolution of postpollination reproductive isolation in Costus [PDF]

open access: yesSexual Plant Reproduction, 2009
Reproductive isolation is critical to the diversification of species. Postpollination barriers may be important in limiting gene flow between closely related species, but they are relatively cryptic and their evolution is poorly understood. Here, we review the role of postpollination reproductive isolation in plants, including the various stages at ...

A standardised framework for classifying estimates of reproductive isolation. [PDF]

open access: yesEvol Lett
Understanding reproductive isolation (RI) between lineages is a central goal of speciation research. While the strength of RI has been estimated across a broad range of taxa, synthesizing these data remains challenging, partially because we lack a common

What is reproductive isolation? [PDF]

open access: yesJ 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 ...

Patterns of reproductive isolation in a haplodiploid mite, Amphitetranychus viennensis: prezygotic isolation, hybrid inviability and hybrid sterility

open access: yesBMC Ecology and Evolution, 2021
Background Evolution of reproductive isolation is an important process, generating biodiversity and driving speciation. To better understand this process, it is necessary to investigate factors underlying reproductive isolation through various approaches

Post‐pollination barriers contribute to coexistence of partially pollinator‐sharing Arisaema species (Araceae)

open access: yesEcology and Evolution, 2023
Reproductive isolation plays an important role in maintaining the species integrity of sympatric close relatives. For sympatric Arisaema species, interspecific gene flow is expected to be effectively prevented by pre‐pollination barriers, particularly ...

Postcopulatory, prezygotic reproductive isolation

open access: yes, 2023
Prezygotic reproductive isolation has traditionally been studied from a precopulatory perspective even though postcopulatory events have been known to influence success at fertilization.

Evolution of reproductive isolation in plants [PDF]

open access: yesHeredity, 2008
Reproductive isolation is essential for the process of speciation and much has been learned in recent years about the ecology and underlying genetics of reproductive barriers. But plant species are typically isolated not by a single factor, but by a large number of different pre- and postzygotic barriers, and their potentially complex interactions ...

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

open access: yesPLoS 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.
