Misleading Mollies
TLDR
It is discussed that effects of socially influenced mate choice are best explained as male adaptations to reduce the risk of sperm competition in a highly dynamic mating system with frequent multiple mating.
Chapter 5 Learning and Mate Choice
TLDR
This chapter illustrates how learning is involved in the mate choices of fishes and emphasizes the important roles that different kinds of learning, particularly social learning, play in sexual selection.
Chapter 12 Evolutionary conservation biology
TLDR
The geographic distribution of poeciliid biodiversity as well as associated threats are reviewed and the impact of nonnative poECiliids on native species and ecosystems is considered.
Behavioural individuality in clonal fish arises despite near-identical rearing conditions
TLDR
It is found that substantial individual variation in behaviour emerges among genetically identical individuals isolated directly after birth into highly standardized environments and increasing levels of social experience during ontogeny do not affect levels of individual behavioural variation.
Using asexual vertebrates to study genome evolution and animal physiology: Banded (Fundulus diaphanus) x Common Killifish (F. heteroclitus) hybrid lineages as a model system
TLDR
The cellular and molecular mechanisms leading to a sexual reproduction in vertebrates and the known genetic and epigenetic consequences of the loss of sex are reviewed and the current research on the genomic causes and consequences of a transition to asexuality is described.

THE EVOLUTIONARY ECOLOGY OF GYNOGENESIS
TLDR
Sperm dependency is not only the defining feature of the biology of gynogenetic metazoans, it is also a major puzzle in evolutionary biology and a serious challenge to theory.
Incorporation of subgenomic amounts of DNA as compensation for mutational load in a gynogenetic fish
TLDR
In the Amazon Molly fish Poecilia Formosa the authors have detected a process that appears to compensate for disadvantages of asexuality, namely incorporation of subgenomic amounts of DNA from a bisexual host species by microchromosomes.
Parasites in sexual and asexual mollies (Poecilia, Poeciliidae, Teleostei): a case for the Red Queen?
TLDR
The Red Queen hypothesis, which states that sex is an adaptation to fast-evolving parasites, is currently one of the most recognized explanations for the ubiquity of sex and predicts that asexual lineages should suffer from a higher parasite load if they coexist with closely related sexuals, is tested using four populations of the sexual fish species Poecilia latipinna and its asexual relative PoECilia formosa.
Benefit to male sailfin mollies of mating with heterospecific females.
TLDR
It is shown that males gain a benefit by mating with female gynogens in an asexual-sexual complex of fish, and gynogenetic species might persist because selection favors males to be sexually parasitized.
