Multiple factors contribute to reproductive isolation between two co-existing Habenaria species (Orchidaceae). [PDF]

open access: yesPLoS ONE, 2017
Reproductive isolation is a key feature that forms barriers to gene flow between distinct plants. In orchids, prezygotic reproductive isolation has been considered to be strong, because their associations with highly specific pollinators.

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 ...

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.

The evolution of reproductive isolation in Daphnia [PDF]

open access: yesBMC Evolutionary Biology, 2019
Abstract Background The process by which populations evolve to become new species involves the emergence of various reproductive isolating barriers (RIB). Despite major advancements in understanding this complex process, very little is known about the order in which RIBs evolve or their relative contribution to the total restriction of gene flow during

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

open access: yesPLoS 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 ...

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 ...

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

open access: yesEcology 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.
