The Amazon molly Poecilia formosa is a gynogenetic all-female ovoviviparous fish. Gynogenesis is a special form of parthenogenesis; sperm is needed to trigger embryogenesis. Males do not contribute to the genome of ameiotically produced all-female offspring. In this unique mating system, asexually reproducing females have to rely on heterospecific matings with males of two closely related sexual host species, P. latipinna and P. mexicana. This asexual / sexual species complex is a unique model… 
Geographic variation in female mate-copying in the species complex of a unisexual fish, Poecilia formosa
TLDR
This work shows that mate-copying is exhibited by the sexual species P. mexicana and P. latipinna, and the asexual P. formosa, the only known case of heterospecific mate- Copying in the Amazon molly and hypothesizes that an added benefit to males lies in the signal value of copulations.
Influence of male harassment and female competition on female feeding behaviour in a sexual–asexual mating complex of mollies (Poecilia mexicana, P. formosa)
TLDR
Differential interests between the sexes regarding the number of copulations can result in sexual harassment, and other factors such as food competition and female mate choice may affect female feeding efficiency.
Seasonal plasticity in male mating preferences in sailfin mollies
TLDR
Potential causes for the variation of a sexual preference for conspecific females and how nondiscriminating male mating behavior can be adaptive in this asexual--sexual mating complex are discussed.
Variation in male sailfin molly, preference for female size: does sympatry with sexual parasites, drive preference for smaller conspecifics?
TLDR
Variation in male preferences could have important ramifications for the maintenance of Amazon mollies, as well as for the evolution of female size.
Behavioural and life‐history regulation in a unisexual/bisexual mating system: does male mate choice affect female reproductive life histories?
TLDR
The findings of the present study confirm that male discrimination against unisexual females leads to reduced reproductive output in unisexuals, and the observed magnitude of differences in targeted life histories between the two types of females is unlikely to be the sole factor regulating stable coexistence in this system.
Effect of predation on male mating behaviour in a unisexual-bisexual mating system
TLDR
The results suggest that thecost of predation is higher than the cost of mating with heterospecifics, and that the presence of a refuge may reduce this cost, which could explain the continued maintenance of Amazon mollies.
Effects of Female-Female Aggression in a Sexual/Unisexual Species Complex
TLDR
It is shown that female competition can in fact be quantitatively measured and that these aggressive behaviors are costly to perform, but sexual competition, access to resources, and position within the shoal are all possible functions.
Turbidity affects association behaviour in male Poecilia latipinna
TLDR
How turbidity as a source of visual noise might affect communication among individuals and how this environmental factor might contribute to the stability of this sexual-asexual mating complex in nature are discussed.
How to go extinct by mating too much: population consequences of male mate choice and efficiency in a sexual–asexual species complex
TLDR
It is concluded that male behaviour does not fully prevent but delays extinction, yet this is highly relevant because low local extinction rates strongly promote coexistence as a metapopulation.
