The role of hybridisation in the origin and evolutionary persistence of vertebrate parthenogens: a case study of Darevskia lizards

This work uses a set of microsatellite markers to characterise the origins of parthenogens in the lizard genus Darevskia, to study the distinctiveness of sexual and asexual taxa currently in sympatry, and to analyse the evolutionary consequences of interspecific hybridisation between asexual females and sexual males.

The ghost sex-life of the paedogenetic beetle Micromalthus debilis

An extraordinary case where sexual adults are resurrected in a species of beetle that reproduces by parthenogenetic paedogenesis, without the production of adults, and an ancient female sex ratio bias that predates the loss of adults is suggested.


Investigation of the variation and evolution of reproductive systems in Aptinothrips, a genus of grass thrips comprising four species, reveals different causes of asexuality in different species, opening new perspectives for studies on the maintenance of mixed sexual and asexual reproduction in natural populations.

Evolution and comparative ecology of parthenogenesis in haplodiploid arthropods

The results strongly suggests that transitions to parthenogenesis are more frequent in large sexual populations and/or that the risk of extinction of parthenogens with large population sizes is reduced.

Origin and Genetic Diversity of Diploid Parthenogenetic Artemia in Eurasia

The results indicate that there are at least two, possibly three independent and recent maternal origins of parthenogenetic lineages, related to A. urmiana and Artemia sp.

Exceptional cryptic diversity and multiple origins of parthenogenesis in a freshwater ostracod.

Hybrid asexuality as a primary postzygotic barrier between nascent species: On the interconnection between asexuality, hybridization and speciation

The results suggest that hybridization leads to sexual hybrids at the initial stages of speciation, but as the species diverge further, the gradual accumulation of reproductive incompatibilities between species could distort their gametogenesis towards asexuality.

Apomixis as a Facilitator of Range Expansion and Diversification in Plants

A seven-step evolutionary model is presented to explain the role of sex → apomixis shifts on geographical cytotype distributions, and the potential consequences of reversals apomIXis → sex on plant diversity.

A drastic change has occurred over a short period, involving the replacement of one strain and a corresponding change in reproductive mode along a riverine environment, and it is suggested that the parthenogenetic strains have increased in abundance primarily downstream.

Phenotypic Variation in an Asexual-Sexual Fish System: Visual Lateralization

Comparing the visual lateralization between Amazon mollies and sailfin molly from San Marcos, Texas shows similar levels of variation inVisual lateralization compared to the sailfinmolly, and further investigation into the source of this variation –clonal lineages or plasticity—is needed to better understand the coexistence of this asexual-sexual system.
