Data from: Facultative use of thelytokous parthenogenesis for queen production in the polyandrous ant Cataglyphis cursor

open access: yes, 2013
The evolutionary paradox of sex remains one of the major debates in evolutionary biology. The study of species capable of both sexual and asexual reproduction can elucidate factors important in the evolution of sex.

The evolutionary significance of parthenogenesis and sexual reproduction in the Australian spiny leaf insect, Extatosoma tiaratum [PDF]

open access: yes, 2016
© 2016 Dr. Yasaman AlaviThe costs and benefits of sexual reproduction has long been a subject of debate in biology. The paradox arises from the fact that theoretically, sex is associated with many costs, yet it is the most prevalent mode of reproduction ...

Elimination of a specialised facultative symbiont does not affect the reproductive mode of its aphid host

open access: yes, 2007
International audience1. Microorganisms that manipulate the reproduction of their hosts through diverse mechanisms including the induction of parthenogenesis are widespread among arthropods. 2. The pea aphid, Acyrthosiphon pisum, shows a variation in its

The Dawn of Asexuality: Investigating the early stages of parthenogenesis in wild populations of Megacrania batesii

open access: yes
Theory predicts that reproducing parthenogenetically could confer advantages over sexual reproduction. Yet, paradoxically, parthenogenetic lineages rarely persist over evolutionary timescales. Facultative parthenogens – animals able to reproduce sexually

Sex ratio theory for facultative parthenogens: from fortuitously optimal stick insects to the origin of haplodiploidy in Hymenoptera

open access: yes
Sex ratio theory usually assumes obligate sex; rare exceptions with facultative sex typically consider idiosyncratic cases of cyclic parthenogens. Here, we construct a general theoretical framework for facultative parthenogens.

Evidence of facultative parthenogenesis in three Neotropical pitviper species of the Bothrops atrox group = Evidencia de partenogénesis facultativa en tres especies de crótalos neotropicales del grupo Bothrops atrox

open access: yes, 2020
: We examined four suspected cases of facultative parthenogenesis in three species of a neotropical lineage of pitvipers of the Bothrops atrox group. Reproduction without mating was observed in captive females of B. atrox, B. moojeni and B.

An Independent Observation of Facultative Parthenogenesis in the Copperhead (Agkistrodon contortrix)

open access: yes, 2015
Among reptiles, reproduction in the absence of males is often assumed to result from long-term sperm storage. Through the application of molecular genetic tools, biologists are beginning to recognize that facultative parthenogenesis can also explain such
