Sperm-Dependent Parthenogenesis and Hybridogenesis in Teleost Fishes
, 2009 In so-called unisexual teleost fishes, a broad spectrum of evolutionaty stages with varying amounts of sexual elements has evolved. These range from pure sperm-dependent parthenogenesis (gynogenesis) without or with different amounts of paternal leakage ...

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

Parthenogenesis in Mayflies (Ephemeroptera)
, 2020 The evolution and maintenance of sexual reproduction has been one of the major questions in evolutionary ecology for the last decades. Sex and reproduction are not synonymous, although they are often linked since the vast majority of animals reproduce ...

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.

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

Molecular ecology of facultative methanotrophs [PDF]
Methylocella spp. are facultative methanotrophs, able to grow not only on one carbon molecules e.g., methane or methanol, but also on multi-carbon compounds e.g., acetate, succinate and malate.
