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.

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

The Evolution of Reproductive Isolation Beyond a Strong First Barrier in Speciation Between Micro‐Allopatric Host Races of a Phytophagous Ladybird Beetle, Henosepilachna diekei [PDF]
Ecology and EvolutionReproductive isolation often accumulates unevenly during speciation, with some barriers evolving early and others appearing only after further divergence.

Phylogenomic timetree-calibrated speciation clocks for Caenorhabditis nematodes reveal slow but disproportionate accumulation of post-zygotic reproductive isolation. [PDF]
PLoS GeneticsReproductive isolation and genomic divergence both accumulate over time in the formation and persistence of distinct biological species. The pace of "speciation clocks" quantified with pre-zygotic and post-zygotic reproductive isolation, however, differs

Reproductive isolation arises during laboratory adaptation to a novel hot environment [PDF]
Genome BiologyBackground Reproductive isolation can result from adaptive processes (e.g., ecological speciation and mutation-order speciation) or stochastic processes such as “system drift” model.

A history of studies of reproductive isolation between Drosophila pseudoobscura and D. persimilis [PDF]
FlyDrosophila pseudoobscura and D. persimilis are a sister species pair that have been used as a model for studies of reproductive isolation and speciation for almost 100 years owing to their close evolutionary history, well characterized genetic ...

Partial and asymmetrical reproductive isolation between two sympatric tropical shrub species: Cnidoscolus aconitifolius and C. souzae (Euphorbiaceae) [PDF]
Ecology and Evolution, 2023 Reproductive isolation is conferred by several barriers that occur at different stages of reproduction. Comprehensive reviews on the topic have identified that barriers occurring prior to zygote formation are often stronger than those that occur ...

Reproductive Isolation, Prezygotic
, 2016 Prezygotic isolation is one of the major forms of reproductive isolation which appears between developing species. Here the causes of prezygotic isolation in sexual species are described in detail.

Pre- and Post-Zygotic Barriers Contribute to Reproductive Isolation and Correlate with Genetic Distance in Cucumis [PDF]
Plants, 2023 Hybridization between Cucumis species, including cultivated melon (C. melo), is hampered by Interspecific Reproductive Barriers (IRBs). However, the nature of IRBs in Cucumis is largely unknown.
